Two full frame bodies or full frame and crop sensor?

For weddings, or any once in a lifetime event, you obviously need a second body. Two 5D Mk IIIs would make total since because any different model will have some controls in different places. In a more generic setting, I mostly shoot FF, but it is handy having a crop for the extra reach. Even if one takes the position that cropping a FF is better than the image quality of a crop body, I don't think that is the entire picture. If I am shooting at a long distance, I can see my subject better with the crop.

I just got back from a once in a lifetime trip to Easter Island and Machu Picchu. There was no way I was going to travel that far away with one body and one lens! I am not a pro, so I don't own a 5D3 or a 1DX. I took my 6D with 24-105mm and a 60D with 70-200mm f/4 IS. This combination covered all my needs. I could have taken my 5Dc but then I would have had two kinds of batteries and two kinds of memory cards.

Aside from what I consider a special case - weddings - you need to look at the whole picture. I couldn't carry everything I own to Easter Island, but I do take four bodies on vacations in the car. I keep at least three bodies with a wide range of lenses ready to go at a moment's notice. An elk or an eagle isn't going to wait around all day for you to get your gear setup! In the 70s and 80s I always had two bodies, one loaded with Plus X and one with some kind of color film. One body didn't cut it back then, nor does it today.

If you plan to continue doing weddings a second 5D III would be your better option. Even if I have never done a wedding, I have a couple of friends doing them and they always state they need to go with 2 cameras and backup of almost every piece of gear, if something breaks down. Otherwise they would have to deal with a very pissed off bride after having ruined her day... A second 5D III would be better than a 6D to simplify your handling and not having to dig around menus.

For nature and wildlife instead a 5D III plus a crop body it's way better. You can skip on teleconverters and have reach with better quality at the same time.

Maybe you need 3 cameras :P

Lol maybe!

I own the 5D3. When I wanted a second body as a backup or for wildlife, I went with the 7D, and just recently bought the 7D2.

If you're planning on shooting wildlife, a crop-sensor camera is going to give you more reach (more pixels on your subject) than your 5D3. I use the 5D3 for portraits and landscapes. I use my 7D for wildlife.

Having noted that, the shutter on the new 7D2 is so quiet, I wouldn't hesitate using it for weddings in a heartbeat. It would perform very well as a portrait/wedding/event camera, too.

I have a 5DIII, which i love... eventually i would love a second camera (I use my wifes 100D as a back-up/second body when she lets me). Initially I thought i would wait for the 5DIV, but the 7DII is appealing as it would add length to my wildlife shooting... 5D for low-light situations and the 7DII for nice lighting and length! hmmmm... Tough call!

It's a tough call to make. If i where you, i would just take a minute to revel in the fact that our problems revolve around which DSLR should we get as a 2nd body! ::)

FYI... this pic might be out of context, but it low-light capabilities are important... this was shot after sun-set at iso 12800 5DMKIII + 500mmLII... this is where having FF shines... some slight noise-reduction but not too much! I would never ditch my 5D, but the addition of a 7DII could be beneficial!

I don't run photography as a business, though I am using 2 bodies, 5D3 for FF, and just traded 7D against 7D2.
From the backup point of view (both FF) a 6D or another 5D3 would have been consequent. But as non-pro the additional features (video, GPS etc.) and reach of Crop and 7D2 were desirable. I didn't want to spend same money for a 6D which would only sit in my trolley waiting for the 5D3 to fail. That's why 7D2. Though, lens selection for parallel use of 2 bodies gets trickier. Due to the crop-factor, with the typical lens combos, you'll either have an overlap or a gap, when using FF and Crop bodies in parallel. But as regards handling, 5D3 and 7DII are perfect siblings!

A backup camera is just that, a backup and would rarely see the light of day. A 7Dmk2 crop sensor would give you more shooting versatility, with more reach and FPS.

If wedding and events is your main area, then for sure take the 5D3. Once I started FF I did no longer use my 7D (which will be sold now). Afterwards I added a 1Dx, as action is my primary area. For sports that's great. Even the 5D3 is good for sport (better AF compared to 7D). Wildlife asks for longer lenses. I even mentioned that the 200-400 1.4x lens is several times to short. For that reason I recently bought a 7D2. But the last one will never being used for a wedding. There I would use only FF.

So as a backup camera in your case, I would go for a second 5D3.

Get the second 5D3. I did and am thrilled with it. One with a 24-70 f2.8 and second with a 70-200 f2.8 II is a killer combination.

If you get a crop for a second body, you will often be switching lenses between the bodies. There was a time when my 7D was my backup to the 5D3 and I spent a lot of time moving the 70-200 between the two based on whether I wanted the reach, versus the pop and sharp detail on the 5D3. Ultimately the pop and IQ on the 5D3 outweighed any reach advantage of the 7D.

Great shot. Amazing at that ISO. I've never shot with that lens but with the 400 5.6 I get similar results shooting wildlife while there not moving much in low light. It's amazing being able to use ISO that high with the results. And your right it's a good problem to have deciding which second body we need!
