Sorry, another "which Camera should I get"? 5D/7D

I've read quite a few threads with pretty much the same advice needed, so apologize in advance, I just can't make my mind up. First I decide 5Dc then 7D, and back and forth I go.

I've been shooting weddings for 4-5 years now, exclusively with a pair of 40D bodies, 17-40, 70-200 2.8 non IS, and a 50 1.8. I also have 2 580's, 4 550's etc etc, more than enough lights and accessories.

I really like using the 40D, but I'd like an upgrade. I find myself using more off camera flash than I want to in order to avoid noise.
I want the 5d II, but would optimally rather wait for the next Gen before I splurge more than I'm comfortable with, whenever that may be. So I have narrowed it down to the 5Dc which I can flip later while enjoying the IQ benefits of FF right away. Or, I can get the 7D which is a major upgrade in terms of features and usability, but maybe not as good IQ. I will then relegate it to sister camera when the new 5D comes out.

I'm personally leaning toward the 5Dc and the better IQ, I can work with whatever Camera. But every time I read the 7D feature list, I get all excited, I imagine it would feel fast an crisp shooting with one.
My concern is, do the benefits of the older 5Dc outweigh what I would get with newer technology in a 7D? What would you do?

Thanks to all.

I shoot weddings with two full frame bodies and a crop. I am considering switching to only two 40D bodies for next season and ditching the FF bodies. I've learned FF is FAR from a necessity to do an excellent job at any wedding.

You would benefit a lot more from lenses than a body, like a 17-55 F/2.8 IS. I have found having a set of primes gets me through just about any situation, and it'll go a LONG LONG ways to helping you shoot at lower ISO.

My proposed wedding kit for next year is:

two 40D bodies
17-55 IS
10-22
Sigma 30 1.4
50L
85 1.8
200 2.8L

The 70-200 F/2.8 IS I might keep around just for ceremony usage.

This would be MORE than adequate to cover weddings in any light, paired with your knowledge of off-camera flash. I mean, slap the Sigma 30 on and you can shoot at THREE ISO STOPS LOWER than you can with your 17-40L. ISO 800 on your 40D will always look better than ISO6400 on a 5D2.

Just a different thought... my two cents.

As a 5D2 owner who shoots landscapes and makes BIG prints, I love my rig.
But.....if I was shooting weddings and was using available light even some of the time, I'd go for the 7D I think.
My old 5Dc was great but the focussing just wasn't that good in poor light particularly.
And it doesn't matter how good anything else is, if you miss focus you have nothing.

I just ordered the 7D myself as I mentioned in the other post. One of the many reasons I eventually chose the 7D over the 5DII are the rumors of the 5DIII which is *supposed* to be coming out soon. I figured I'd just save up and pick that up when it comes out, or pick up a used 5DII for cheap.

There is no right or wrong answer to this and either camera could do a great job. Personally, I grew up shooting film and just like the sweeping look I get out of my 5D2; it seems more natural to me. But I shoot with crops, too, and they do an equally good job. Given the choice, I don't think you can make a bad decision.

I'd get the 7D for flash control.

I think you have to decide if it's more important for you a better overall iq (and specially high iso iq) or some bells and whistles. I have met many photographers who use 5d and 5dII and don't want to go beyond iso 400.... if you are one of this... well take the 7d. If you are like me you really would like the possibility to shoot without worry at iso 1600 with the 5dc. Besides I think you can find a used 5dc for less money than a new 7d.

I'd go 7D's and hold out for the 5DIII. Once you use a 7D (and it's flexible metering and focus system), you'll see why. ....and I own two 5DII's.
