Canon 7D - The Brazil Field Report

Stephen Mick

Totally Usable
Some of you may be familiar with the type of work I do, others may not. Basically, my niche is adventure-sport and travel filmmaking, generally focused on fishing and water sports. My goal with this post is to provide some "field intel" on using the 7D and related gear, and hopefully to offer some insights on how to use the camera as a tool in some particularly challenging conditions. I hope some of you find this information useful.

Background
The Assignment:
- Follow professional bass angler Casey Ashley on a journey into the Amazon basin to catch tucunaré, or peacock bass, a big, angry, colorful fish found nearly exclusively in the jungle.

The Gear:
- Two Canon 7Ds
- Canon 17-55 EF-S f2.8
- Canon 16-35 f2.8L
- Canon 70-200 f2.8L IS
- Tokina 11-16 f2.8
- Sigma 30mm f1.4 (Courtesy of the Wookie)
- 77mm Singh-Ray VariND Filter
- Canon BG-E7 Battery Grip
- Zoom H4n
- Sennheiser MKE-400 Microphone
- Zacuto Z-Finder and Tactical Shooter
- Manfrotto 755CX3 Tripod with 701HDV Head
- Nexto NVS-2500 Video Pro Storage/Oflload Device
- Four 32GB SanDisk Extreme III CF Cards
- Scott A2 10-Weight Fly Rod and Waterworks Large Arbor Fly Reel
NOTE: I did take other gear (wireless mic, intervalometer, small portable light, etc.), but as I did not end up using them, I did not include them here.

The Location:
- Brazil's Rio Negro, an enormous river deep in the Amazon, near the border of Brazil, Venezuela and Colombia.

The Conditions:
- Hot. Hot. And more hot. Daily temperatures were in the upper 90s, with humidity in the 80-90% range. Shot mostly in full sun, with occasional cloud cover and the odd rain shower.


Field Report
Ergonomics
I start with this one, because for my style of shooting, it's absolutely key. There's no way around the fact that these HDSLRs are not designed as video cameras, but offer video capabilities as an "added bonus." And nowhere is this more apparent than in ergonomics. SLRs were made to grab single frames, or a series of frames, at a time, not for extended takes of hand-held shooting. And the weight distribution changes significantly depending on which lenses you have on the camera. Slap the 17-55mm on the 7D and you could shoot hand-held without a stabilizer. Swap the 70-200mm on there and you're asking for pain.

The key to making this camera work from an ergonomic standpoint is to use a rig that lets you have one hand free at all times. With the Tactical Shooter, I ended up using a number of different configurations depending on the lens I was using. This allowed me to always have a hand "at rest" while supporting the camera with the other hand and my shoulder. Whatever rig you choose, test it out at home before using it in the field. After a few days, I had pretty well dialed-in my stabilizer for maximum comfort and performance. But I wish I had spent more time in advance getting it rigged and balance for each of the lenses I was using.


Ease of Use
I won't spend a lot of time on this topic, other than to say that the 7D's menu system and button placement feels just about perfect to me. I switched back and forth between 1080p and 720p, and could easily do this in under five seconds. Camera functions are intuitive and clear, even for someone with "limited" DSLR experience.


Lenses
For the most part, I never took the 17-55mm f2.8 lens off one of the 7D bodies. For general-purpose shooting, this is a great lens. At 17mm, I was able to get great shots in close quarters on the water. And at 55mm, I was able to get close enough to action happening out on the water about 50 yards away. Now, you can't get super-tight with this lens like you can with the 70-200mm range, but for all-around shooting on the water, this was my go-to lens.

The boats we were shooting/fishing out of were very small. And this is where the Tokina 11-16mm lens really came in handy. At 11mm, you get a near-fisheye effect, making a monstrous river look even larger. At 16mm, the perspective "flattens" out to a more normal wide-angle view. The constant f2.8 aperture of this lens is really, really nice. It's no wonder this lens is so hard to find.

Some of the time, we were shooting from a "chase boat" to talent in another boat. This is when the 70-200mm lens got the heaviest use. I never found myself wishing for "more telephoto" than this lens offers on the 7D, and the constant f2.8 is really nice for shallow DOF accent shots. The downside is that this lens is a f'ing beast. It's really heavy, and as wonderful as the Zacuto Tactical Shooter is, it wasn't really much help with this lens. I wish I had taken my Varizoom DV Media Rig, but it was just too big to fit in my bag, and would have put me over the baggage weight limit. But even as big as the 70-200 is, the shots you can get with it make it worth the pain. The IS can be a bit loud, but usually the subject was so far away I wasn't really looking for good audio, just quality video.

I see a lot of people asking whether or not Image Stabilization (IS) is important. It is, period. I found myself leaning on the 17-55 and the 70-200 most of the time, simply because of the IS. This shoot was, to me, the definitive test of whether or not IS helps when shooting video, and let me tell you, it does. It allowed me to shoot hand-held at 200mm and still get smooth shots, even from a small boat running 40mph across choppy waters. In ten days of shooting, I used my tripod twice, both times for interviews. Everything else was handheld, and the IS performance allowed me to get shots I could not have gotten without it, for sure.

For shooting on the boat at night, the Sigma 30mm f1.4 was the go-to lens. Even in situations with very little ambient lighting (like one fixture on an outdoor boat deck), I was able to shoot without ever going above 1250 ISO.

As great a lens as the 16-35L is, it never saw much use, simply due to the lack of IS. Some will say that at those lengths IS really isn't necessary. To them, I say spend a day shooting what I shoot and then see how you feel.

All in all, the lenses delivered great images under some very, very difficult conditions.


Audio
For almost all of my shooting, I used the Sennheiser MKE400 connected directly to the 7D. Sure, AGC is not a good thing, but when you're shooting for 8-10 hours a day, syncing that much double system sound, even with something like PluralEyes, is a no-go. And to be perfectly honest, the audio from the Sennheiser/7D sounds perfectly fine for "field shooting" where ambient sound and limited dialog is the goal.

I did have a wireless microphone system with me, but the days I had planned to use it (with the Zoom) ended up being rainy and windy, not a good combination. I also had a Tram TR-50 lav that never came out of my bag for the same reasons.

For interviews, I used the Zoom H4n, with built-in mics only, placed close to the talent, with the Sennheiser MKE on the 7D for backup/reference audio. The Zoom audio is certainly cleaner and "warmer," but the sound straight from the 7D is completely "usable," even with the AGC enabled. To be fair, in the jungle there's quite a bit of ambient sound (bugs, birds, water), so the AGC was really not being "triggered" at all. But regardless,

Where the Zoom really earned its keep for me was in recording wild location sound. Having good, clean sound effects and wild sound is a key element in being able to create a quality sound mix, and to be honest, it's often one of the things I neglect to do on shoots. But the Zoom is so easy to use, it makes recording these kinds of location sounds a snap. And if it's easy, it's more likely I'll do it more often. I can't recommend the Zoom highly enough.


Accessories
Get a Z-Finder (or something like it). End of discussion. This is an absolute necessity.

Get something to put the camera on, even when shooting handheld. It just makes life easier. Whether it's a SpiderBrace, a DVRig or some home-brewed shoulder mount, it's an investment that will pay off with better footage and greater comfort.

I just picked up the Canon BG-E7 battery grip a few days before the shoot, and I really like it. I especially like having the option of using "AA" batteries to power the 7D. One night, while camera batteries were supposed to be charging, the boat's power had gone out. So I woke the next morning to only two fully-charged batteries. I loaded six lithium "AA" batteries into the grip and had plenty of power for a full day of shooting. It does add a little bit of weight and bulk to the camera, but I actually think the grip makes the camera easier to hold.

The tripod I used was chosen simply for its light weight and easy leveling. I can't say enough good things about this piece of gear. For an inexpensive travel tripod, it's a great choice.

A lot of people ask about which CF cards to get. My SanDisk Extreme III 32GB cards worked flawlessly through the entire shoot. Never a dropped frame. Never a dip in bit-rate. Just ten days of reliable performance, which I what I expect from my gear.


Workflow
Each night, I would offload the raw footage from the CF cards to the Nexto NVS-2500 storage unit. We did have power on the boat we were sleeping on, so I didn't have to use the battery pack for the Nexto. Every single card was copied and verified successfully, with not so much as a dropped frame or bad clip. I was even able to hook up the NVS-2500 in "drive mode" to review footage right off the drive. I can't overstate how nice it is to be able to review raw footage right off the cards without having to transcode or even import footage (a la P2 or SxS). With a card reader, I was easily able to review clips in QuickTime Player on my laptop. At the end of the shoot, I backed up all of the footage to an external G-Drive for safe keeping.



A RANDOM NOTE: One of the biggest problems that most people don't think about in conditions like these is condensation. If you keep your gear in the room with you, keep the air conditioner off and the windows open. Or find a secure place outside the room to stow your gear. Otherwise you're risking losing a considerable amount of shooting time, and quite possibly even damaging your camera and lenses. The point: don't forget about these things in the field, or they'll bite you in the ass.
 
Conclusions
I won't go into a full-on "pros vs. cons" list here. If you've read the above, you've gotten all there is to get. Using cameras like the 7D for a job like this certainly presents challenges that more traditional video cameras do not, ergonomics, workflow and audio among them. But I knew I wanted/needed two cameras for a trip like this, and with the baggage weight restrictions I had to work with, taking two EX1s or HPX170s was not really an option. I carried most all of the gear listed above in my Think Tank Shape Shifter backpack, and while it was heavy, it did the job.

As I mentioned in another thread, overheating did occur in both camera bodies from time to time. But when you're shooting in extreme heat, this didn't come as a surprise to me, and is one of the reasons I had two 7Ds with me at all times. When one overheated, I'd pick up the other and start shooting. Generally after a half-hour of rest, the "hot" camera was good to go. I can't say exactly how long the cameras would go between heat warnings, but generally I'd say each camera got "hot" once per day. An inconvenience? Yes. But not a real problem, as I was prepared for it.

Of course, it all comes down to image quality. I'll try to have some samples up by the end of the week, which I'll embed here, but it's hard to describe just how good the footage can look. Yes, I ran into a few shots where moire was apparent, but out of about 20 hours of footage, to only have a handful of these shots is not really an issue for me. Based on the footage I've looked at so far, the 7D more than passes my test in delivering stunning images in a small, affordable package.

If a client called tomorrow and asked me to do the same shoot again, I'd have no problems packing up the 7Ds and using them again, even with the challenges they provide.


What Would I Do Differently?
There are certainly things I would change, both in the gear and in how I used it.

I likely wouldn't bring some of the things I didn't end up using. I'd also (probably) simplify my lens assortment by adding the 24-105L and (maybe) dropping the 70-200mm lens. (It's just so heavy.) I might also consider going with the 70-200mm f4.0 IS lens instead of the f2.8 to save a bit of weight. And I wouldn't bring any normal-range zoom lens that didn't have Image Stabilization.

I'd also make the space to bring the Varizoom DV Media Rig. Having a shoulder mount that offers either a "support pod" or counterbalanced weights would be really, really nice to have. When you're working ten hours a day on a boat, taking as much of the weight of the camera out of your hands is a wonderful thing, but the Zacuto Tactical Shooter really wasn't designed for this purpose.


One Final Note
This is not meant to start any kind of deep discussion or commentary about this camera versus that camera, but I truly believe that this new crop of HDSLRs have the power/ability to make us "better" shooters. I say this simply because many members of this board don't come to the collective table with very much experience behind the camera, and certainly not the wealth of experience many of the longer-term members have.

From personal experience, I can tell you that the first time I picked up the DVX, I switched it into fully-auto mode and went shooting. I didn't need to concern myself with things like shutter speed or aperture or trivial things like that, I just pointed it at what I wanted to shoot and hit the red button. But I quickly realized that easy is not always "good," and the DVX made it too easy to shoot without a real understanding of how all the ingredients came together to create the look I wanted. Over time, and with the help of sites like this, I came to be a "passable" if not accomplished shooter, as I understood more about how things worked. (I came from more of a stills background, by the way, so the learning curve for video may not have been as steep as it could have been.)

Enter the HDSLRs. With nothing but manual controls to deal with, there is no "crutch," whether that be auto-focus, auto-exposure or any number of other "auto" features most current camcorders offer. In many ways, these HDSLRs force us to have a better understanding of how aperture, focal length and sensitivity (to name a few), work together to create the images we see and the look we want. We can't "offload" any tasks to the camera to handle automatically for us, and I think shooting this way encourages more "trial and error" and ultimately a faster and more productive education as to how images come together.

Also, because of the "crippled" audio features, we're also forced to take sound more seriously as its own element, one that's often overlooked in the quest for "shallow DOF" or the "film look." Now we have to actually think about how we're capturing audio, where the microphone is and should be in relation to talent, and we pay more attention to capturing location "wild" sound we'll use later to make a richer audio mix.

Having to "think" about these things, either out of choice or necessity, means we have to pay more attention to every aspect of the task at hand. This need to "focus" on how images are created, and how sound is captured, is what I believe, has the power to make many of us better and smarter shooters. HDSLRs are not perfect, and I don't believe they represent any kind of "revolution" in how we work. But while they're not the best tool for every job out there, in the few short months I've used both the GH1 and now the 7D, I believe they've made me a better shooter, and the proof is in the footage I see now when I shoot with whatever camera is in my hands.
 
Brilliant report, Stephen. Thanks for taking the time to make such a comprehensive report, and we look very much forward to seeing some of this footage!
 
Stephen, thanks for taking the time! This is the best run n' gun field type report I have read on the 7D or probably any DSLR. You are the man, some friends are headed out in a sailboat for the weekend and will be taking a 7D with them, I'm going to forward this to them.

Can't wait to see the footage!
 
Wow, I vote this for a "Thread of the Year" award. Good stuff Stephen..very informative and encouraging. I agree that these new crop of DSLRs can "help" us become better shooters by forcing us to become more aware of things we probably took for granted (Iris, manual focus, audio etc.). Thanks.

Oh...and I can't wait to see the footage either.
 
Congrats Stephen . Hope the toekoenarie was tastefull :)

Can you comment about using the Fader ND or Vary ND . Did you miss having a built in NDfilter ?
 
Thanks for the report. Great stuff. I love shooting my 7d as well and I try to convince other that it's more than just a STILL CAMERA that can do video.

Ebay has a pretty cheap $100 counterbalance shouldermount. It even has an optional spring loaded support brace attached to a belt.
 
I'm glad so many are finding this information useful. Thanks for the feedback!

Everts-
I certainly didn't miss having a built-in ND filter on the 7D. The Vari-ND is actually a better solution, in my experience. Since the effect is gradual as you turn the filter, the change in exposure is less "harsh" than switching from one built-in ND filter to another, as with the HPX or EX1. Now, I try to never change exposure in the middle of a shot, but when it's necessary, it's necessary, and the Vari-ND makes it easy.

Also, while I like shallow DOF for certain shots, it's not appropriate for everything I shoot. For example, when someone is fishing, you never know where the fish might hit. At f2.8 with the Vari-ND in place, pulling focus as the lure is retrieved can be challenging. In these situations, I removed the Vari-ND and used B&W 0.4 or 0.6 ND filters instead. This let me open up the aperture to f8 or even f11 in full sun, giving me much deeper DOF.

Stephen:

Outstanding information, thank you for taking the time to compose and post it. I went through some of the same things this Summer when I shot a doc in France with the 5D MKII. Not as extreme conditions as you went through but a lot of the same issues you encountered.

I am supposed to go to Denmark for a week to shoot some EPK at the Copenhagen G20 Summit on Global Warming. Not sure if I will take my HPX170 or my 5D MKII. I only have room for one setup or the other. I am leaning toward the 5D MKII but need to speak to the client to determine how they want to use the footage.

Your experience should be required reading for all HDSLR users.

Thanks, Dan! Coming from a User like you, that means a lot.

I think one of the biggest factors in choosing (or not choosing) to use the 7D is final delivery. For this project, the final product will be SD DVD and web, with potential HD web delivery at a later date. If this had been a broadcast job, I would have sucked it up and found a way to take my EX1/Nanoflash combination. I would still have tried to take one of the 7Ds, just for those shallow DOF shots that the 7D excels at.

I'm a big believer in choosing the right tool for the job, and for this job, two 7Ds did the trick.
 
Wonderful! and Thank-you for taking the time to give back to the community! I have a HMC 150 and was thinking of getting a 7D for those shallow depth of field shots. I think I will go for it. You covered so many bases. Thanks again

+1 :thumbsup:
 
Amazing report! I'm glad to get some input from someone else that films fishing, and it's awesome to see you packed your fly rod with you! Good to see you are "enlightened" :D Did you end up catching any peacocks of your own? That has been my dream trip since I started bass fishing.

As far as the filming goes, did you feel that you got adequate wide angle coverage with the 17-55 or was it a must to go to the Tokina 11-16? I previously have only had the 28-135 for my 7D (because it's so new, haven't had time to add lenses to the goodie bag yet), but have rented the 10-22 Canon lens and will take it out for the first time on Thursday on a shoot. I'm wondering if I could get away with 17 being my widest or if I truly need something wider. I shoot mainly handheld on foot, not out of boats.
 
Freaking awesome review.

Thanks so much for taking the time to put it together.

I've been vasilating between the 70-200 f2.8 and the f4.

Think I may be pulling the trigger on the f4.

Oh, and make sure you return that 11-16 to me by next week!
 
Add me to the list of 'great review'
Thanks for taking the time to write up your thoughts on the trip.

Having to "think" about these things, either out of choice or necessity, means we have to pay more attention to every aspect of the task at hand.

Brilliant observation.
Never really thought about it that way - but absolutely true.
Great point.


EDITED TO ADD:
I was glad to see the Sigma saw some use... as I was reading your review I was thinking...damn, did my poor Sigma sit in the back the whole time?
That 1.4 is pretty handy when you need it - can't wait to see some of the footage.
:)
