I am fine with what Canon is doing.
There are clearly two paths... There is high ISO performance / more studio / low light - This is the 5DmkX line and FF
There is then a speedier FPS, better suited to moving objects Crop body - which is the 7DMKx line
And if you want both? Go the 1DMKx line.
Not coincidentally the price of a 5DMK III and a 7D MKII combined will be close to... yes... Yes... You got it... The 1DMKX line.
The more I read these threads, the 7D folks want better IQ and the 5D folks want better fps / AF... The amalgamation of both really is a baby 1DMKX, but they pretty much want almost all the features and performance at half the price.
As a 5D MK II owner I would like a little more AF performance and spread, but over all it is fairly solid. If I spent more time shooting action, I would probably have gone more the 7D route, and potentially in the future, will try and pick up a 7D body used for around $1K. I have been very very tempted to sell off my T2i, batteries, grip, and the like for just such a move, but don't want to be caught with out a spare body at the moment.
I do see Canon introducing a Baby 1DX, maybe the rumored 3D... I believe this will be higher MP, with less FPS and less A/F / ISO than the 1DX line and expect it to be $4k - $4.5K
So I expect the 7D MK II to be a $2K body, a little better IQ, same A/F maybe a little more ISO and some faster FPS but still a 18 MP body.
I expect the 5D MK III to be under 25 MP, still in the 21 - 22 MP range, same A/F points, but all cross points and a bit wider spread, a step up in ISO and around the same FPS. I don't expect the 5D MK II to be a sports camera and this body to be the entry FF and $3K to $3.2K
I expect the 3D line to be 30 MP, High ISO, little lesser A/F than the 1Dx, lesser FPS, and $4K - $4.5K so the differentiation between the 1Dx line will be the 3D has higher MP, but the 1Dx remains the king in ISO, A/F, and FPS.
1Dx is the all around top
3D line is a little cheaper, little lesser, but still all around
5D line aimed at studio / FF
7D line aimed at sports / crop
1Dx line is aimed at top pros
3D line is aimed at best of both worlds for the next level (i.e. those who currently carry both a 5DMKII and 7D) and the the 5D and 7D lines are for those one a budget who do more of one style shooting than the other.
Really makes sense to me
