Canon 7D

Would you use a Canon 7D as your portrait and wedding camera over a full frame camera? What would be your lens choices?

Absolutely not. The best lenses for Canon cameras are not designed for aps cameras. For example, the 70-200 2.8 is way too long on a 7D. IMO the 7D is not a serious camera for any kind of pro other than a wildlife photographer.

Absolutely. The best lenses for Canon cameras are designed for all cameras. For example, the 70-200 2.8 is way perfect on a 7D. IMO the 7D is a serious camera for any kind of pro especially a wedding photographer.

I'm sure why Jeremy doesn't think that you can use a 16-35L 17-40L, 24-70L 24-105L or any fixed focal length lens on a 7D, but here is my take. (I shoot portraits, but not wedding so you have to take this from a somewhat narrow pov)

The 24-70 is a great portrait lens for a 7D (or similar) For me even better is the 85 1.8 (I've only played with the 1.2. I don't know it well enough so I don't want to recommend it).

How wide you do want to go. the 16mm and 17mm focal lengths are extremely wide on a full frame but still very wide on the 7D. The difference here might be do you want the 2.8 or 4.0 as a max. f/stop.

Thanks for your help guys

Well, the 7D has a better AF and metering system than most Canon full frame cameras (read the 5D series). Shooting a cropped sensor for indoor formals means you can shoot at f/5.6 and have the DoF of f/8- that can let in some more light, which I prefer. Or even shooting wide open gives you a bit more DoF than you would otherwise have on a FF camera. And when shooting weddings, that can be nice. If I were shooting portraits only (not wedding day portraits) than I would love the DoF that a FF provides. But weddings are run & gun with not a lot of time to establish your shot. The extra DoF is nice. And yes, I know you could up the ISO on a FF camera, but that has it's drawbacks and I am not speaking in terms of noise. As far as lenses go, I have no clue why Jeremy thinks you can use the 70-200 (or others) on a crop sensor. Additionally, many lenses will vignette on a FF sensor whereas on a cropped sensor a lot of the edge issues (sharpness, vignetting etc) are instantly taken care of for you! That's not to say full frame isn't advantageous, but for shooting weddings, a cropped sensor and the 7D in particular would be tough to beat!

Mark, the 70-200 focal length has emerged as a useful focal length over decades of professional use and evaluation. We must all have got it wrong because you think that 1.6 times longer is "way perfect".

If you want to develop a system with a bunch of hodge-podge sensor sizes and focal lengths, that 's your choice. The vast majority of the serious (real) pros I know that work in these industries are using FF sensor cameras. The flagship Nikon cameras are FF and many of the most popular pro Canon cameras are FF. The 24-70 and 70-200 focal lengths have been designed by Canon and other major manufacturers as their flagship focal lengths because they are the focal lengths that photographers need.

So let's go through the list:

1) The 16-35 on a 7D is a 26-56. Not as wide as the 24-70 and not long enough for portrait/tight work.
2) The 17-40 on a 7D is better but it's f4 and has less range than the 24-70.
3) The 24-70 on a 7D is not wide enough for wedding photography when one is working in a confined space.
4) The 24-105 is an f4 and it's not wide enough.
5) The 70-200 is a 112-320. Ask yourself why this focal length did not emerge as a dominant, popular focal length. Because it's too long at the wide end. That is unless the most important thing is reach - as in wildlife photography.

Cheers, JJ

The vast majority of the serious (real) pros I know that work in these industries are using FF sensor cameras.

This is called anecdotal evidence and it's useless. I work with plenty of other pros shooting both portraits and events and almost none of them use full-frame cameras. I also work sports and nobody uses full-frame. However, most use the 70-200.

Jeremy Jackson , Feb 13, 2010; 07:39 p.m.

So Jeff, if anecdotal evidence is useless, why did you cite your own anecdotal evidence? I did make other relevant arguments. Do you have any comments about those? JJ

Jeff Spirer , Feb 13, 2010; 07:41 p.m.

My anecdotal comment was given to point out how it's useless. Neither statement has any statistical validity. People use the 70-200 with a variety of sensor sizes. It's not a bad thing.
