I have a Canon Ti5 now and enjoy it very much. I am wanting to add another camera to my kit. I realize these are full frame cameras and I can use all of my lenses on the new body. From what I am reading the Mark III is a wonderful camera. I am not sure what the benefits of an extra $1000 on top of the Mark III would give me. Reading about the differences between the Canon 5DS R and S, I will need help there also. I would like to hear your opinions and advice.

I have the 5D Mark II and recently bought the 6D. Both full frame. I bought the 6D because it is smaller, light. I love it.

I thought about getting the Mark III, but saved over $2000 by getting the 6D and don't think I am missing anything.

I'm sure others will weight in, but in my opinion, from all I've read, the 5DS / R is a camera with a very niche market (Primarily landscape and studio work). If I was going to by a full frame and those were my choices, I'd go with the 5D III because I feel it is a more versatile all around camera (better low light performance, faster frame rate, etc). The only thing you'd give up is 50 MP, which is really nothing most non-pros need unless you plan on printing a billboard!

Owl, I'm always amazed at how many think the 5s is a niche camera. Will it take an AWSOME portrait or landscape. You bet it will!!
BUT, except for the lower fps, it has the same, if not slightly better focus system as the top end 1Dx! That means that the 5s will take sports at 1/2 the fps but with 3X the mp!!! With that focus system, you don't think that camera will shoot action?!?! Think again!!!!
Same when compared to the 5lll.
I've taken award winning sports shots with my 5ll and that thing has the worst focus system on the planet. The 6 is about the same as the 5ll in good light. Same crappy focus system but with better low light focusing.
I shoot a lot of sports and am considering getting rid of my 7ll and going to a 5s for everything !!
It the same focus system as the 1dx/7ll(maybe better) with 3 times the mp.
Talk about getting amazing bird shots. And let's not forget that you can spend 1/2 as much on lenses and get the same reach by cropping!
But maybe it's just my style as I like to shot with a lot of anticipation and timing. I very rarely use Spray and Pray even though I've got 10fps.
That's just my two cents for what they're worth. ;-)

SS, I did not mean to suggest it isn't a great camera! I'm just relaying what I've read (in more than one review) that is is best suited for landscapes (which you mentioned) and studio work. If the extra fps isn't important, or if the extra megapixels are important (and are willing to spend the $$) then by all means, I'm sure the 5S is terrific.

One review (DPReview), for example, said: "Without a doubt, most photographers don't need 50MP (nor 36MP or 24MP for that matter) but some do, and this places the 5DS (and especially the 5DS R) firmly in medium-format territory for studio and wedding photographers."
I've read similar comments elsewhere. That's not to say it can't do a great job elsewhere.
But, speaking for myself only here, if I were in the market for a FF, I'd be looking at the 5D III due to better low light perf and faster fps. Not to mention less $$ (I would rather put the money into glass).
I'd simply recommend the OP read lots of reviews and watch lots of video reviews and be sure he understands what he is getting and then can better decide whether it is what would fit his shooting style and needs better.

Basil, I wasn't directing my comment so much at you, as all those reviewers that you are talking about! They all seem to say the same thing, and fail to mention that it has a more sports orient focus system than either a 1dx or a Nikon D4. If that does not put it squarely into action territory, then what does? Sure, it can always be argued that double the fps is better for action. It is, but it only takes one fps to get an AWSOME shot.
The same hoards of people that praised the D800 for being so AWSOME, should be saying the same things about the 5Ds but more!!
But it is an expensive camera, enough so that most of the amatuer market won't go there.
As per me, to review it and then say it's a niche camera, is just plain mediocre reporting.
As I said, I'm ready to replace my 7ll with one and I guarantee you I'll never miss the 7ll. Mainly because I know the 5s shoots sports better than my 5ll, and my 5ll was my main sports camera for more than a few years, so I know it will perform at more than a high enough level.
And for those that want to kick the DR and ISO thing into the mix, if you can't figure out a work-around for such a petty performance issue, then that shooter probably can't shoot with anything else anyway!
I have not used a 5s yet but I will as soon cps has them in wide supply. I'm sure I'm gonna be WoW'ed.
Put a 600mm on that thing and shoot tiny birds......, or sports....,WOW!!!! :-)

Would love to see the results! I'm sure it will be amazing.

^^^^THIS.

The 5DIII is one of the best all-around performers on the market... but the 5DR/S are just specialty cameras.

Forget about ANY photography that requires speed or good low light performance.

Landscape and architecture only... forget sports of any type and any moving wildlife photography.

SharpShooter Loc: NorCal

Cholly, that's hilarious!!!
Exactly how many 5s's have you tried on sports or at any action for that matter?!
When you do, report back.
If you're just parroting what you've read, I understand why.
Post us a shot on which you think a 5s will perform poorly, if you can come up with one?
Yes, landscape or any other detail oriented types of photography come to mind.
But with a focus system as good or better than a D4/1Dx, I'm enough of a photographer so that a few other uses come to mind for which the 5s will perform admirably.
Untill I use it, I'm basing it on my experience shooting exactly the kinds of shots that you mentioned, which I've personally shot with much lesser cameras than a 5s, and those lesser cameras pulled off those shots extremely well.
I will post as many shots to illustrate my points as to what the 5s will do, as you post to show what you think the 5's could not do, if indeed you can even come up with just one shot!!!
Those testers/reviewer that think the 5s is only a niche camera, should probably question their skill level as photographers!!!! :lol:

Personally, I'd only buy the 5DS if I was either independently wealthy and money was no object, or if I was a professional and needed that kind of resolution. I have a friend with a 5D III and know it does everything I'd ever need as an amateur and then some. But that's just me (and I don't need to question my skill as a photographer - I know I stink on ice LOL). But hey, different stroke for different folks.

When you say, " I realize these are full frame cameras and I can use all of my lenses on the new body.", it makes me wonder what lenses you do have. Since you have an entry level Rebel t5i crop camera, crop lenses like the EFs kit lenses that probably came with it, were not designed to work with a full frame body. Any third party lenses designed for cropped bodied will also not work on a FF body.

It may have the same AF system as the 1Dx but the AF on the 1Dx still performs better. The spot metering on the 1Dx follows the AF point where the 5D III, 5Ds, and 7D MK II use only the center AF point for spot metering. The 1Dx also has a dedicated DIGIC 4 processor just for the AF system that make is quicker by far.

Thanks Harold!

Sharpie, you know I have not touched a 5DR/S, much less shot one.

I HAVE shot the 5DIII however, and yeah; read about the 50mm 5DR/S. People whose reviews I trust call it a specialty camera... and I believe them.

Niche camera Sharpie.... niche. ;)

Thanks I checked these sites and what I found is the 50D r/s are smaller than the Mark III about the same as the Ti5. The 50D r/s is a full size sensor that can be set to crop size. The Mark III is a bit bigger yet with sensor will increase the clarity of pictures. The 50D r/s trend or direction will replace both at some point in the future but is not there yet. With that said my friends and family can understand why or how much good glass costs not to mention the cost of a camera body. For me its about the quality, fun factor and the outside factor of making a few bucks in the future to buy more equipment.
