So does a 50D but it shoots 1/8000. It seems like a silly thing to limit. I understand they will self limit features to make other products more desirable... But shutter speed? There are plenty of other things that serve that purpose far better than shutter speed... Just my opinion...

Because it comes in at a lower bracket than the pro line...

I've been considering upgrading to the 5D for quite some time now, but it might be kind of a crazy jump from the Rebel T3i to something like this one. I'm currently a student, but I need a professional camera. I shoot weddings, portraits, sports, video, and everything in between so I really need something versatile and something that can do well in low light situations without flash. Would the 5dmkiii be a good choice? I'm willing to save up and pay the higher price if it's worth it. Any suggestions?

I realize this is old, but the 7D/7DII would be the place to look for sports photography in a lower price range. The 7DII offer pro-body level autofocus. The 5DIII is probably suitable, if expensive, and the 6D offers an autofocus system most comparable to the old 30D by comparison. It's not a penalty box in the grand scheme of things, but it wasn't meant for sports at all. You may lose a little bit on image quality with the crop body (Particularly if you compare a 7D to modern DSLRs with Sony sensors), but for outdoor sports, getting the images in focus is going to be more important.

If you shoot RAW video using Magic Lantern, the fast speeds of the CF slot is pretty important in the 5D over the 6D.
Avatar for Aian I. Mazumder Aian I. Mazumder (5:17 PM, July 02, 2014)
That's always an option but at almost $400, I'd personally rather just put that money toward saving up for a 5D. You can't necessarily go wrong with the 6D but the 5D is no doubt still a better camera. The fast speed of the CF card slot is important if you're planning to record RAW video to the card slot. For photography and everything else other than being a professional or high speed/sports photography, the 6D is a great, affordable choice and will get identical pictures (image quality) to the 5Dm3. For video, I'd still save up for the 5D, but that's just my opinion. Both are still great cameras. Obviously the 5D costs a decent amount more but it's up to you if it's worth the money for the upgrades.

Hi Aian, what about VAF-6D moire/anti-aliasing filters? I saw some videos and they actually look great.
Woud you still recommend 5d?
Kwest (9:21 AM, June 22, 2014)
I've filmed a low budget TV show with the 6D and 5dMk2 as back up. I gotta give it to the 6D. The only thing I hate about the camera is that damn moire! Now that I bought a $350 filter for it I'm very happy with it. $1650+350 still out weighs the $3500 for a 5DMK3. Don't get me wrong the 5DMK3 is the king but this fresh prince is just coolin' right now. The real problem is waiting to see if I should get the 1D-C (price drop) or the 5DMK4 or 6DMK2! Dang!

I need to disagree with the final decision. It looks like far to much weight is given to size and weight. (no pun intended.) In nearly every way but price, the 5D3 is the clear winner. In terms of dynamic range and image quality, the 6D might have an extremely slight edge, but it is so minimal as to not really matter.

Frame rate, auto focus, dual card slots, and shutter lag are all significantly better on the 5D3, which are very important features for a pro photographer.

The 3 things that led me to the 5Dm3 over the 6D is 2 card slots, the anti-aliasing filter (rarely gets mentioned), and the much, much better focusing system. For event photography, writing to 2 cards is HUGE, esp a fast write to a CF card. For video, anti-aliasing filter is quite important. If you don't notice aliasing now, you probably will eventually. Because of this, there is no doubt that the 5Dm3 is a much better camera for video. The focusing system is also a huge upgrade from the 6D if you're shooting anything other than stationary shots in the middle of the frame. Those 3 things made me pick the 5D over the 6D.

For someone that doesn't do video, shoots mostly still subjects, and is comfortable shooting to one SD card (many photographers), then the 6D is the better choice at the cheaper price but if the 3 things I mentioned are important, I recommend saving up for the 5Dm3 like I did.

This is such a tough choice! The focusing system of the 5D is definitely
better, I don't think there is any question about that. But in every
other way these two are very comparably similar. The biggest advantages
of the D6 are it's price and built in WIFI/GPS, which if you added these
features to the 5D it would be a thousand dollars more than it already
is. I do portraiture and some events. I tend to think I might get more
usable, in focus shots, especially for weddings and perhaps with
restless children with the 5D. But is the difference so much it's worth
paying an extra thousand dollars? That's the big question. Saving a
thousand dollars could allow me the purchase of a new lens, or some nice
props. I am still very undecided!

The shutter speed is also an issue for the 6D. I mean seriously why include a 1/4000s limitation on a Full Frame? Why not just allow it to do the 1/8000s like the rest of the cameras on the market today as well as its predecessors?

The 5DM3 has a multi-cluster of center points (9 I believe). It makes a big difference for sports or event action. I used to have a 5DMK2 that had the lone center focus point. If you're subject is moving directly towards you you'll probably get some usable shots but if it is moving across the plane then you'll need a lot of luck or perfect timing. The choice is up to each person on what they buy. My only point here is make sure you choose what you need. The 5DMK3 focusing system is very advanced and not difficult to do. It has been a long time since I could say that about a Canon DSLR. If you're shooting sports you will be limited. If you're shooting still life subject then you will probably be satisfied with the 6D. WiFi seems to be an overrated feature to me. I can see few specialized uses but not many in my workflow. I would rather have a higher percentage of in-focus shots than have the wifi option and end up with a lot of out-of-focus shots transferred wirelessly. There are other and better ways to fire cameras wirelessly (at the moment). But again, choose the camera based on your needs and understand that almost no camera is perfect for every type situation, so choose wisely.

Then you must have very still subjects. Fast moving subject such as action or sports requires an adept focusing system, even when your subject is not dead center.

I have never moved my focus point from center. I would never trust that the sensor wouldn't pick a back ground or foreground object and ruin my shot.

Pick your focus point and hold then frame your shot.
I can not think of a time in the past 22 years of shooting that I would want the camera to decide what to focus on.

Just bought a 6D and I am selling my 5D Miii to buy a second 6D.

5D plus wifi = 2 6D's .... no brainier unless you are making thousands of dollars a month from your camera.

I'm going to miss my dual card slot but that is about it. And JPG In the camera for HDR.... Who would want to create a HDR in the field unless it was for fun. To do a good job in HDR it needs to be done in post.

My 2 cents :)

There is one glaring advantage to the 5DMKIII that should be heavily weighted in its favor over the 6D and that is the focusing system, which is well worth the additional cost. The 6D is using a system with only 11 focus points and 1 cross sensor. If you are shooting stationary objects then you'll be OK but if you're shooting anything with any type of movement pay the difference and get the 61 point/41 cross sensor focusing system of the 5DMKIII which compares favorably with the very high priced 1D X. As with every camera purchase, look at your needs first and then match those to the camera. If you're a landscape, fine art or portrait only photographer then the 6D is probably a good choice. If you shoot the aforementioned, plus events, weddings, sports, etc. then upgrade to the 5DMKIII. My personal rule of thumb on buying high cost technology is to always try and buy up if you can possibly afford it. That's just me but given that you are already spending $2K, I think another $1K is worth the investment. You can usually get a refurbished 1DMKIII with warranty from the Canon store for around $2800 which is less then a $800 difference and is definitely worth it in my opinion.
