Crop and Full Frame, Differences?

Would there be any differences for
50D + 17-55IS
vs
5DII / 5DI + 24-70L

in the picture quality, aspect and prospective?
Is there a Big difference in DoF in FF compare to Crop?
and aside from the noise and DoF, are they equally the same?

This thread might help. It is one of the most recent discussions on the topic and has a lot of good info.

Throwing in "Crop vs full frame" in the search box will turn up a bunch of other threads as well. Or look at the "Similar Threads" box at the bottom of this window.

Differences:

1. 17-55 is approx. 28-88 FOV compared to 24-70
2. 24-70 is an "L" lens therefore (almost always) is better than the non "L" lenses
3. DOF is the same - f/2.8
4. I think you will get better results from the 24-70 but not (just) because of the lens, but also because of the new 5DII body (ISO and sensor size/resolution)

The resolution performance difference of the 24-70 vs. the 17-55 is neglible in ordinary shooting, you have to shoot test targets to see a difference in resolution!

Don't forget the 17-55 also has IS to help cover up any photographer shakiness!

Hi "keener"! Can I have a quick question to you?
I see that you have a 50D and also a 5D. I am planning also to move later on to FF - 5DII. My question is about the visible (and therefore subjective) quality of the pictures taken with the two camera - can you judge just looking randomly at your pictures (in terms of quality) which were taken with the 50D and which ones with the 5D?

this is confusing. for the same FOV the DOF for the FF will be much thinner....about 1.5 stops.

If the only difference is the noise that is a big difference in and of itself. The 50D and 17-55 is a great combination and can deliver outstanding image quality. I would opt for the FF alternative as I like the colors and detail out of FF options. But that's me.

What will you be shooting? If you are doing a lot of landscapes you will see definite advantages to the FF solution and if sports to the crop body solution.

Good catch!

Oops - you are right, thank you for correcting me.

Hey there!

I actually posed the same question to myself. I took them both out for a spin to see if there was a difference. What it came down to was ISO performance between the two. Up to ISO 800 I can not really tell the difference between the two (in real world use [meaning no pixel peeping]). Beyond that, the 5D starts to shine over the 50D.

There are other obvious difference too though, like the great pixel count of the 5D2, but I didn't really buy the 5D2 for its 21 megapixels. I actually like to shoot it in sRAW1 because I'm so used to that size from previously using a 40D. I'm slowly starting to shoot more 21mp images though. Then there's the DOF topic. I won't bore you with the details here, have a read at that thread I posted above.

It is a tough debate if you are trying to choose between the two. The 5D2 is not for everyone, neither is the 50D for everyone. Just like lenses, you have to try them out and see what works for you, regardless of what people suggest. Just because I say you should get the 5D2 for its awesomeness doesn't mean it is the camera for you

I have both because I shoot family portraits and weddings where you need two bodies. Plus it is nice to have two different cameras where you can make use of their specific advantages in my opinion.

that was my first thought so i thought i would just watch for awhile .

I am just debating on myself whether I will get a FF body in the future (3yr+)
my XSi serves me well,

Does the DoF of FF really makes the picture "pop out"?
I enjoy using my Sigma 30mm 1.4 @ 1.4, but if it is a FF+ 50L/85L,
Would it make the picture a million times better?

Noise isn't really a factor to me in XSi, LR2 always help in reducing excessive noise
and normal ppl (non-pixel peeper) won't even notice there's noise after.

I came from film camera, and somehow picture I took from the past (using +ive film) seems more 3D than what I am taking now.

keener - many thanks for your kind explanation!
