Notes from my first PX270 shoot

Over the years, sites such as this have been exceptionally helpful to me in making purchasing decisions and obtaining answers to issues not directly covered in the user guides. So in the spirit of "giving back", below are my crew's notes from our first shoot with our three new AJ-PX270s, purchased to replace our three AG-AC160s, which were purchased to replace our three DVX-100Bs, which were purchased to replace our Sony TRV900s....but that was a long time ago.

Yesterday's shoot was a daytime indoor/outdoor wedding. Ceremony outdoors, reception indoors. We started at 7:30AM, and wrapped at 5:30pm.

We were shooting at 1080/24PN at AVCi100 (not because we wanted to....see "One other thing", below)


Let's start with the positives:

1) Without question, huge step up in picture quality over the AC-160.

2) The servo zoom is outstanding. Been waiting a long time to be able to do a slow push-pull without fear that the slightest twitch of my finger would hit a dead zone in the rocker.

3) Having an extra 10db of pad on the audio inputs (as compared to the AC-160) meant not having to put an inline pad on our shotgun mics...less weight, less stuff sticking out....it's a good thing.

4) Over the course of a long day, the PX-270 being lighter than the AC160 was very welcome.


Negatives:

1) I won't reiterate what is already in another thread regarding OIS issues (see: PX270 OIS problem?), other than to say that if my three units are representative of the entire production run, then this camera is currently unsuitable for handheld work...unless, of course, the operator is as stable as a jib and can run with OIS off.

2) Though I knew this going in (thanks to other user reports), it must be restated that THIS CAMERA EATS BATTERIES. With all the things to think about in a 3 camera (4, if you count the GoPro) shoot, I couldn't believe that my overriding concern was: Would we run out of battery power? The day was a seemingly never-ending cycle of battery swapping/charging.

If anyone from Panasonic (or an aftermarket competitor) is monitoring this site: Please come up with a battery that can last at least 2 hours. I don't care if it sticks out the back of the camera!

Happily, we never did run out of power, but looking ahead to my religious service work (where swapping batteries is not an option), I will clearly have to retrofit my setups for AC power, as a typical religious service outruns a fully charged battery by at least 15 minutes.

3) Due to #2, above, we were constantly trying to maximize battery life by powering-down the cameras between shots. Big problem with that: With two 64GB microP2 cards it can take 10-15 seconds for the camera to fully initialize on power-up. Missed the beginning of a few shots impatiently waiting for the camera to be ready.

4) All that power cycling/battery swapping takes a toll on timecode synchronization....and if you believe the user guide, you're supposed to do a black balance after every power cycle/battery swap. REALLY?

5) Not being able to quickly jump in/out of VFR mode is a real killer (functionality is tied to a scene file). This was so easy on the AC160...gotta believe the same methodology can be employed here.

6) In bright scenes, the text on the LCD screen is barely visible. The viewfinder, however, is great, as it has black banners at the top and bottom of the image. It would be great to have the option to place translucent banners over the top and bottom of the LCD screen's image...or anything else to make the text pop.

7) The REC indication should be more obvious. Again, in bright scenes it's hard to see the thin red type.

8) As noted by others: With an accessory mounted on the cold shoe, opening/closing the LCD is a challenge, if not impossible. Obviously the hardware is what it is...but thought it was worth mentioning.

9) With so many setup items buried in menus, it would be great to have the option to jump to the last menu item, as opposed to starting over from the top of the tree each time (and if this already exists, I apologize...only had the cameras a few weeks!)

10) Every time I open the audio control door, I think it's going to break. Maybe it's stronger than I think, but boy does the latch feel flimsy.

11) I miss the solidity of the AC-160's handle...just felt right....and the post by another dvxuser member showing his cracked handle (from his first shoot) gives me pause. Let's just say I was VERY careful when mounting our SmalHD monitors on their NOGA arms this weekend...never was concerned with the AC-160.

12) And though I know it would have added significantly to the cost, a faster lens in the telephoto range would have been so welcome...going in tight in an already dark scene is a killer. Not sure what a faster lens would have added to the street price of the camera, but I would have gladly (?) paid more for a better lens.


Close, but no cigar:

During my research I was so excited to see that zebras could be enabled on the video output. This has been a wish list item of mine for years. But alas, the zebras are only on the downconverted analog output, which is not suitable for our use. Here are two setups that would benefit from Zebras on the SDI/HDMI outputs:

For theatrical work I am often the cover shot/director, with the other cameras getting entrances/exits, close-ups, etc. I monitor the other cameras at my camera position via an SDI feed from each. Often I am instructing the cameramen to either "iris up" or "iris down" based on what I see on the monitor. This, as most people know, is entirely subjective. Zebras don't lie.

And during yesterday's ceremony shoot (outdoors), where we had our heads buried in the hoods of our smallHD monitors, not having to constantly glance between the camera's LCD and the smallHD monitor to verify exposure would have been a MAJOR benefit.

While probably locked in hardware, let me just say:

• Optional zebras on the SDI/HDMI out would be a game changer...and
• Having the ability to enable/disable the overlays independently on the HDMI and SDI outputs would be a little slice of heaven. Really.


One other thing:

Though I thought I did a pretty thorough job of researching all the latest offerings before choosing this camera, one thing escaped me (and was not helped by the sales person at my dealer): I was led to believe that we could forgo P2 cards in favor of fast SD Cards for Long GOP work and that Long GOP actually looked better than AVC i100, which requires P2 cards!

Only problem: Currently, the camera doesn't shoot VFR in Long GOP, and Long GOP50 is not currently supported for 24P, which is what we shot yesterday. My bank account is now much lighter, having purchased 9 64GB microP2 cards (3 per camera) and the AJ-MPD1.


Conclusion:

From a picture quality standpoint, this was a great purchase. And though I hadn't budgeted for all those P2 cards, I think that in the long run a P2 workflow will be more efficient, as offloading from the AJ-MPD1 is lightning fast.

But Negative Item #1 is a show stopper, and may result in an awful large return to the dealer based solely on a true manufacturing defect. REALLY HOPING IT DOESN'T COME TO THAT, as based on all my research for the type/frequency/budget range of the event work that we do, on paper this is the best choice out there.

No worries. I was amazed to see the PX-270 draws 19.5 watts at full clip. That is a lot for a 1/3" camera. At first I was scratching my head but realized that is the price for all of the high level processing going on. It is the 19.5 watt power draw that makes the 2/3" camera-like images possible. So I would rather have the great images and buy more batteries than have a 5 hour battery life with just good images.

Hey Jonathan, thanks for taking the time to give a detailed report, it's very helpful and much appreciated!

I only had the PX270 briefly for a "first look" evaluation, so you have much more experience with it than I do, but looking at your list of negatives, I might add:

1) I won't reiterate what is already in another thread regarding OIS issues (see: PX270 OIS problem?), other than to say that if my three units are representative of the entire production run, then this camera is currently unsuitable for handheld work...unless, of course, the operator is as stable as a jib and can run with OIS off.
Sorry you ran into that, and according to gkantziper they've acknowledged it as an actual bug. Hopefully it will be something that can be fixed rapidly and via download.

2) Though I knew this going in (thanks to other user reports), it must be restated that THIS CAMERA EATS BATTERIES.
As said by someone before, this camera draws a lot of power. The AC160 draws around 11.8 watts or so, IIRC, but this thing has the entire processing engine from the PX5000 in it, so it pulls 19.5 watts. That has a corresponding effect on battery life, of course. Panasonic rates the included 5800mah battery at 90 minutes of continuous runtime, and the CGR-D54 (5400 mah) battery at about 85 minutes.

Bassman's suggestion of the Ikan battery may help quite a bit. According to Ikan's marketing, a CGR-D54 delivers 38.8 watt-hours, and the Ikan battery claims 65 watt hours. Given Panasonic's rating of 85 minutes for the D54, that should put the Ikan in the range of a continuous recording time of 142 minutes, or about 2:20 of continuous record time. Not nearly three hours, but should deliver well over two, which is what you asked for, right?

Another alternative could be just a traditional battery belt. I know, nobody buys a lightweight camera just to have to wear a six-pound belt on their hip, but seeing as the PX270 does have a DC input, you could use something like a simple $59 Bescor belt with a cigarette lighter->12v DC plug adapter, and with 108 watt-hours on tap that should deliver somewhere on the order of four hours of continuous runtime. Or, spending a little more you could get a lithium ion belt with about the same capacity (98wh for $169) but with much less weight, it's about 1.3 pounds.

3) Due to #2, above, we were constantly trying to maximize battery life by powering-down the cameras between shots. Big problem with that: With two 64GB microP2 cards it can take 10-15 seconds for the camera to fully initialize on power-up. Missed the beginning of a few shots impatiently waiting for the camera to be ready.
Using a longer-capacity battery may minimize or eliminate this as a concern.

4) All that power cycling/battery swapping takes a toll on timecode synchronization....and if you believe the user guide, you're supposed to do a black balance after every power cycle/battery swap. REALLY?
Again, longer-capacity battery should minimize or eliminate this as a concern.

5) Not being able to quickly jump in/out of VFR mode is a real killer (functionality is tied to a scene file). This was so easy on the AC160...gotta believe the same methodology can be employed here.
My immediate reaction was to say "why not just use the scene file dial?" To my horror, re-examining the pictures, I see that there is no scene file dial! That's a big mistake... but... looks like they tried to minimize the hassle by including a scene file option for a user button. So -- in the old days, with a scene file dial, the way I'd do this is to set up (for example) scene file 1 as your normal usage scene file, and then scene file 2 as your VFR scene file (all other settings exactly the same, but with VFR set to ON). Then you'd just toggle the wheel between 1 and 2 for VFR on and off. Without a dial, it may take a step or two more, but should be infinitely better than trying to call the menus up. Choose one of your user buttons and assign "SCENE FILE SEL" to it. Then you should be able to enable VFR with just a couple of button presses (press the user button, then select scene file 2, done.) Again, I don't have a PX270 in front of me so I can't describe the exact process, but that's what the ops manual seems to say how it should work.

9) With so many setup items buried in menus, it would be great to have the option to jump to the last menu item, as opposed to starting over from the top of the tree each time (and if this already exists, I apologize...only had the cameras a few weeks!)
I'm not sure if this is what you mean, but there is a customizable User Menu where you can choose which items to appear in the fast-access user menu (i.e., when you just press the menu button quickly, instead of holding it down for three seconds). So if you have specific menu items you use all the time, you may want to customize your user menu to include just those items.

I think a bigger battery, or a battery belt, may go a long way towards alleviating a lot of the hassles you encountered, and I think that possibly some of the tips mentioned above might help with many of the rest. That OIS thing is a problem; I hope they issue a fix promptly, even if it doesn't yet include all the other things they've been planning on doing (such as adding 25p to LongG50, etc).

Barry,

Thanks for taking the time to chime in.

Regarding the Ikan battery: Once the OIS issue is sorted out, those babies will be my next purchase! That B&H link brought a huge smile to my face. That should address "Negatives" 2-4.

Regarding VFR: For this weekend's wedding we set two different User buttons (one on the left side and one on the grip) to directly access the Scene File menu. This gave the operators options, depending on which hand was free. The steps involved are/were:
1) Stop current recording
2) Press button to access Scene File menu
3) Scroll to appropriate Scene File
4) Exit the menu
5) Press Record

Sounds pretty simple, right? Well when the bridge/groom have just had their kiss and about to walk down the aisle, every second counts. In my opinion, there are too many steps here…and if you overshoot the correct Scene File with the adjustment wheel or rocker switch, you waste valuable time and risk missing the shot completely. This past Saturday my last-second decision was not to go for VFR on the recessional….I just didn't trust myself to get it right. Again, this was so simple on the AC-160…one Scene File with VFR enabled. Two quick button presses on the side of the camera to switch on/off. And now that I'm thinking about it, with all those User Buttons on the PX270, it would be absolutely wonderful to be able to assign VFR on/off to one of them. Then it becomes 1 button to enable/disable!

Regarding Negative #9: Yes, I am aware of the customizable menu. Problem is that at this stage of the game I've found myself loading it up so I don't have to endure the 3 second delay for accessing the System menu. What I'm wishing for is a way to return to the LAST menu the NEXT time the menu is displayed. So, for example, if I'm knee deep in the color correction menu (pun intended) and exit the menu, the next time I press Menu, the system could take me back to where I was when I exited. Lots of ways to accomplish this…one could even be a "Last" selection at the top of the tree.

Regarding OIS Issue: Placed a call to Panasonic regarding the OIS issue this morning. Anxiously waiting to hear back from Engineering or the Product team.

I tested the Ikan batteries and I was able to record 3 hours and 15 min with the LCD open.

Regarding timetables, I received an e-mail from a Panasonic rep I have been in contact with stating the WiFi and file transfer features will not be available until Jan. 2015! I had to read it a few times to make sure of the dates. There must be an "all hands on deck" situation to fix the more pressing issues. Don't know what is going on over at Panasonic these days...
 
As I imagine upgrading my geriatric HPX170, Ive sat on the sidelines through the 250 series hoping they might improve the lens. Despite the wonderful codec options and all the higher end options, seems like Panny has lost a bit of the mojo. No scene file dial; WHAT? I guess I'll wait a while longer.
