Comparison Video / Explanation: Canon Rebel T2i vs. Canon EOS 7D

They need to shoot the same subject, using both cameras with the same settings. By the way, I don't have a huge problem with the 1/40th shutter - but 1/50 is widely

I actually did just that with the fish tank, not sure why we didn't end up using that, guess just to cut down on the time and keep it simple. I'll see if they still have the footage and if so i'll throw a short video together of just the comparison video

Great job Loren. Any time somebody questions your age, it's because their jealous they didn't know what they wanted to be at such an early age.

You are coming up in a time where high quality productions cost pennies compared to just 8 years ago.

Thanks for the video. I have 5D Mark IIs and wanted some slow-mo. Since it doesn't look like we'll be getting it next week with the firmware upgrade, how do the 7D and T2i stack up with it comes to shooting slow motion?

Use the $2,000 you saved from not having to buy a 5D Mark II and go buy some lenses. Or at least rent them.

Other than the $70 Canon 50mm f/1.8, DO NOT put cheap glass on any of these cameras. Cheap bad lenses equal bad images.

Well, I can't afford a 5D mkII so I cannot dump a lot of money into new lenses, although I'd like to. Right now I am liking the Canon 24-70mm F/2.8... Probably the next lens I buy.

Thanks man,
As for the slow motion, i haven't done any tests yet. I've seen some slow motion done with the 7D though, and Philip Bloom also said that it is do-able. Use the 60p (1280X720 only) and 120th shutter speed to keep the 180 degrees.

Quick google search found a nice little video with some water:

But as for personal experience, nothing yet, but soon!

Yesterday I tried out some quick slow motion tests, although I didn't upload it, I put 720p60 footage in a 60fps timeline and slowed it down to 35% and it was still fluid looking. I tested the difference between a slower shutter speed and a faster one and anything above 250 significantly sharpens the motion.

Pffft. Teach people how glass differs, not what they should and shouldn't use. All tools can find a use, even the cheap ones. I always get flack for putting $50 lenses on my $3000 D700 yet nobody bothers to even look at any photos taken with the lens. Why be so prejudiced?

Let's me clarify my statement.

Inexpensive lenses are great. I love saving a buck. I have saved some coin using eBay, and looking for used lenses on Fred Miranda and KEH.

You mention a $50 dollar lens. Half my portfolio at www.gregorystorm.com was shot using a Canon 50mm 1.8 that I got off eBay for $65. I loved that lens before it broke. I'll go with the 1.4 next time but the 1.8 served me well.

When I say cheap glass, I don't mean inexpensive. I mean cheap, poor quality. A lot of these bargain basement lenses are from companies you've never heard of. You don't need L glass to get a great images, but buying a lens with all plastic parts thinking it will compare to L glass is a waste of money.
 
Thanks for posting the comparison video. Really useful info.

But the one question I have is about the bit-depth. I always hear that bit-depth is very important for resolution and the Canon 5D Mark ii & Canon 7D have a 14-bit depth. But I can't find any info on the Canon Rebel T2i. Why is that? And if someone does find out the bit-depth for the Rebel, how would it compare to the big brothers Canons. What would be the noticeable difference? Thanks.

They only have 14-bit depth for raw stills, not video, I believe. I would be surprised if the bit-depth is higher than 8-bit from what I've seen online. It's probably the same as for their JPEG stills (that would be 8-bit).

I think the video is RGB, not YUV colour space, correct me if I'm wrong. I think that's a function of the CMOS.

A lack of latitude is what currently separates the DSLR's from the big boys. (ie, red)
 
What is considered cheap price wise for a lens? When I am lens shopping, the prices are ALL over the place! :)

I used craigslist and picked up a Sigma 30mm F1.4 lens for $375 which I thought was a good deal. I use this lens more than any other and the quality is outstanding with it. I was surprised.

I try to research a lot before I buy a lens, like I did with the Sigma 10-20mm that I also bought of craigslist, as I wasn't sure if I should save up and get the Tokina or Canon that is similar in size. However, having used both the Canon and the Sigma, I couldn't justify the cost difference because I couldn't see a difference in what I was shooting. Since shooting video is a lower resolution, I'm just not sure how to compare what I really need sometimes.

After seeing all the comparisons of the 7D and T2i, my advice to others has been get the T2i and put that extra money into some nice lens to REALLY appreciate what you can do. I love my 7D, but when I am moving on to the next technology, only the lens are coming with me :)
 
I have four Olympus OM lenses 35,50,135,300 that I bought in the late 70's that look pretty damn good on my T2I with a $15 adaptor. In less than a year there will be another camera that will be better and have more value than the T2i. Buy quality lenses, tripods, and lighting, they will last you a long, long time.

hahah well, I'm actually the one who did the write up, so they felt it was appropriate for me to do the video=] When I started working at EVS, I was surprised at the lack of this exact response, sure every once in a while people will ask for a second opinion as they don't completely trust mine, but truth is, I got where I am because I know things, and not who I know. Although I'm sure from here on out I will depend much more on the friends i have made, and can't thank them enough for the opportunities I've already been given, but it all starts with the want to know.

P.S. I'm seventeen:tongue: hahaha

Don't feel bad ;~) I was technical director for a nationally known/respected theatre when I was 19. That was a LONG time ago. It's sometimes strange learning things from "kids", but then I think back and go hey that was me once upon a time. Keep it up. I respect knowledge and that doesn't nec. come with age.

Hi Everyone!

I own GH1 and I'm thinking about moving to Canon 550D or 7D and I wonder whether what you see on an external monitor is the same thing you see on the camera screen.
Is the refresh rate on the monitor the same when you record video?
Is the resolution the same? I've read in this thread that the output (to the monitor) from 550d is 720p and the output from 7D is a bit bigger. Is it much easier to pull the focus with 7D than with 550D?
 
I don't own on 550D, but from what others have told me, it changes resolution during record.

I DO own the 7D and can say, the video stays consistent when I record AND it is a lot easier to pull focus. I use a smallHD with it. Works GREAT!
