This product was bought used but came looking very clean and well taken care of.

Consistent blow-outs in Evaluative mode (center dot with circle around it). For example, if taking a picture of a bird in bright sunlight where the background is darker (such as the trees lining a river) consistently blew-out the highlights on the bird. This occurred EVEN WITH highlight tone priority turned on. I had to leave my exposure setting at -2/3 for all such situations and even got some blow-outs there, too. And no, 'spot' isn't a solution either, as spot often has very non-deterministic results.

Of course, the camera otherwise is a fine improvement over prior models. I particularly like the very fast live-view AF. But Canon made some basic mistakes with this camera. Some could be fixed with a software update, others possibly not. I'm hoping Canon can work up some software fixes for these issues. They could make a good camera great. I'm a little confused as to why Canon would make so many basic mistakes on their almost top-of-line camera.

I upgraded from a Mark II that I used like a rented mule. I had a couple of "must haves" for the upgrade. First, I needed a more sophisticated autofocus system. The Mark IV delivers in speed and accuracy, and it's easily customizable with both the switches and touchscreen. I also wanted more dynamic range, and at least they got into the Sony ball park. I would complain about it still being behind the Nikon D810, but it delivers enough to get the job done and it makes up for it in low light / high iso performance. It also makes up for it, in a an overall sense, when paired with good glass - something that too often gets missed by the spec sheet nazis. From a performance perspective I am very happy, and from a usability perspective I'm also very happy. The touch screen, along with the generally sensible Canon menus and switchology work for me. It has everything I want in a camera, and does everything well, so overall I'm very pleased. It's a good solid piece of equipment that really delivers when paired with a good lens.

shipped the next day and delivered 2 days later, I needed a new camera for a project and the 5D Mark IV came just in time

I love the bundle and mic

Update: Went from just wanting an upgrade and being overall happy to absolutely loving it. 30 mp is a good bump up in terms of resolution without being monstrous (they are still big files), but the best thing is that good hand held shooting is still possible (this thing rocks with the Canon 100-400 Mk II). The touch screen is amazingly useful and quick - wouldn't want to be without it now. The dynamic range is where it needs to be, the autofocus is fantastic, and the high iso performance is exceptional. The customization options (including the touchscreen) have made this into an amazing piece of equipment for me. I almost got lured down the Sony / Metabones adapter road, but I'm glad I didn't. The whole little camera / big lens idea doesn't make sense, and why give up any features or performance? I can use my canon glass and speedlights and do everything I need to do without compromising anything.

As reviewed on other web sites. This is the last great DSLR.

Upgrade from a T3i and WOW what a huge difference.
