This post has many parts, the bottom one is my review of the 5D3 after a week with it.
1st - Ummm, Correct me if I am wrong - but the 5D3 I am holding in my hand, isn't that the replacement for the 5D2, just as the 5D2 was the replacement for the 5D?
2nd note - I read about a new lens mount, not sure why Canon (or its clients for that matter) would support that kind of idea. If Canon is going to play games, and basically require us all to buy new glass - I can tell you now that I will, as many others will, leave the Canon brand. If on the other hand, they have two models, like they do the C300 - fine, let them do whatever they want. But I made a decision to go with Canon only a few years ago, and I can easily change my decision if they plan on forcing us to reinvest into glass all over again. I would like to ask other Canon owners to stand with me, refusing to buy into a new lens mount paradigm. I will actually go so far as to contact Canon owners and do a call campaign to keep them from that product.
I like your forum, been reading it for years now. This message is for the Canon R&D guys to read carefully, not against you, as I can tell by your comment that you feel the same way about the lens mount issue. I don't even want to have to use a converter - the more points of contact, the less weather sealed it will be. But at the very least, yes, there better be a converter. And it better be free if they are going to pull this crap on us.
part 3- As for the 5D3 - I am a HUGE fan. I have been playing with it for about a week now, and I have to admit that the tweaks are very significant. The 5D2, sitting next to it on my desk is a fantastic camera as it is, we all know that, but the 5D3 is obviously a product of many peoples input, and they took it all into consideration when they released this model. I would like to see the time restriction removed for US bound models - I understand the problem in the UK. But for me, that would be a fantastic programming update, even if it costs money, because when I am shooting a wedding, I have never once been happy to stop and restart the recording. The low light is at least 3-4 stops better, and the expanded ISO range (H2) is fantastic, its nearly night vision!! I have some sample pictures, unedited because adobe is still working on the file type - but it shows how crisp, clean, vibrant the images are. But I did find a flaw.... I have already on two occasions have the lens unlock and detach from the body without warning. Something that has NEVER happened to me on any body in the history of my life - happened twice in two weeks. I will let you all know what Canon says about this. I am also working on shooting video and stills side by side with the 5D2/5D3 to show the difference. I know its just a megapixel difference, and people who count MP's as the "end all, be all of human existence" - Ferris B., I would suggest they buy the newest Nokia camera phone with over 40MP's.... but I now understand what Nikon owners were saying about quality over quantity. This 22MP sensor is fantastic. I hope those of you who that are thinking whether or not to buy one, chose to get one. Not because I own stock (which I don't) but because you will very quickly realize, as I have, that this sensor is a whole new ball game, and Canon just hit a Grand-Slam.
I don't use a lot of HDR, but the in camera HDR is actually usable. Sure, you can blow it out of proportions and make it nasty or hard to look at, but you can control the HDR down to a normal level, all without software. I shot a few pictures at the park, and the onboard HDR actually made the shot look like a medium format quality picture. Adding just a little to the image. Side by side with the original I can see how much just a little boost can do. Most of my previous dealings with HDR were not as great. But the fact that you can control the HDR - and use it wisely or go nuts with it, there are various degrees to choose from. When you add this to the various picture styles the number of outcomes is truly infinite. I also like the fact you can have more than 3 shots in the AEB settings. without picking up the camera two feet away I think its either 7 or 9 images... ok, ok, let me look here.... ok, its 7, but each can be up to /-3, so that can go from 9 to -9!!! and another option is multiple exposures - and that has up to 9. Haven't used that yet though.
The number of AF points is fantastic - and although I will probably never use this, you can use them to display the electronic level in the viewfinder. Thats not useful to me, but maybe someone needs that... in any case, its neat. But the other, more normal uses for those AF points are much more important and useful. It even lets you have a different set AF point for landscape and portrait. I don't think the 6D2 had that, did it?
The Dual cards are great, and they give you a lot of options on how to use them. I personally will use one as my primary, and one as a backup of my wedding shots when a corrupted card can get you sued. This way, before you ever back up your files, you already backed up all your files. FANTASTIC. But you can also use them so that one can playback while the other records, or auto switch when one is full. Two other options that I don't quite understand fully, gotta play with it more... aw shucks, I'm gonna hate playing with my brand new camera LOL
Sorry this is so long, being my first post I wanted to really JUMP IN and get yelled at by all of you at once

JK.

<strong>Odds & Ends
</strong>A know source has mentioned a couple of things in regards to products coming in late 2012.</p>
<p><strong>Mirrorless Announcement
</strong>I’m told that Canon’s foray into the mirrorless world will begin in August with an announcement. Photokina is in September, so it makes a lot of sense to announce at the end of summer.</p>
<p><strong>New Full Frame
</strong>A suggestion that Canon will announce an “entry level” full frame camera in the fall of 2012. A true replacement to the 5D Mark II?</p>
<p>That would bring about 4 new full frame cameras in the span of about a year if we include the coming 4K DSLR. Most assume that will be a full frame camera.</p>
