"According to my sources Sony has chosen to use a completely new sensor for the upcoming professional SLT (Translucent) camera. The sensor will have 24 Megapixels but don’t worry, I have been told the noise performance of the sensor is equal if not better than current 14-16 Megapixels Sony sensors used for the NEX and A33/A55 cameras. It will feature the highest resolution APS-C camera on market (The Canon 7D is on top with the 18 Megapixel sensor). The Sony A77 will be released by mid 2011 because Sony needed time to develop an almost perfect camera. There will be many innovations (Paul Genge of Sony UK said that “this camera will include such high specification features that current A700 owners will be amazed“). It will have an improved BIONZ processor (based on the current A33/A55 processor), micro af adjustment and record 1080/30p, 720p60 and 720p30 (But we can’t exclude last minute improvements like 1080p24). I also do know that Sony original plan was to release the A750 with Optical Viewfinder but I don’t know yet if Sony will indeed bring that prototype to the market (let’s say there is a 50% chance)."

Your first point is incorrect. Once you have held and used a real pro camera then you will see and feel the difference.
You mean the fact that the 'pro' camera is a big, heavy brick?

Your second point is correct that it's not the camera, but the man. Man can only make up so many shortcomings though and in the same situation, with the same man, the pro camera will always do a better job and do it faster.
Do you have any idea how many "pro" photographers use the Canon 5D or the 5DII? Have you ever held one? The 5D is of pretty average build quality and pretty slow. It has an AF system that is not any better than the K-7.

I know a couple of guys who are still using the Canon 40D for their work and they are both making well above average incomes.

not to mention it's as expensive as a FULL-FRAME? even worse.

Are there any compelling reasons (except maybe better high ISO performance) for choosing the A33 or A55 over the GH2 if video is important?
it has a bigger sensor? more DOF and FOV?

the k20 k7 k5 are all pro camera as good as d700..it0's not the camera that makes a pro it's the man behind...and your gallery show exactly my point.
it's more of convenience of use, aside from DOF and FOV advantage. the D700's performance is blazing fast and accurate. the point is,you'll have more keepers and don't miss to shoot those moments that you needed to get. I'm not sure how the K-5 will perform, but the K20D/K-7 aren't at par with the D700. the K-5 however seems to be on par or better than the D700 in terms of High ISO and DR. but camera performance/response is yet to be seen if it's really as good as the D700.

A good professional photographer has the right equipment for a given project. Sometimes that's a tough, but bulky, system with a half-dozen expensive lenses. Other times it's a point and shoot (really).

I apprenticed with a successful professional photographer (lots of annual reports, commissions, studio and advertising work) for four years. Not counting large format stuff, we used Mamiya, Hasselblad, Linhoff, and Nikon. We had Nikon bodies ranging from totally manual (FM2s) to the enthusiast grade (8008 and N90s) to professional systems (F4s). We used them all.

If I was a full time professional (and I'm not), I would own several different camera systems and use them where they were strongest. I could see myself using Pentax for street photography, and casual portrait work. The new 645 would be a great studio camera. I'd probably also have a Nikon body and a couple of lenses for high-speed or low-light work.

Unless someone was paying me, there's no way I'd just use one brand - and even then, I would think hard about it before I said yes.

I know a lot in my area and some snubbish bunch. the AF system of the 5DII is not that convincingly fast as the 7D, but AF is not the only concern here but higher reso, and DOF/FOV control. actually there is a debate which one is better. overall, the 7D is better and a speed specialist, the 5D MKII is more of a landscape, studio, event specialist. for anyone who is tight on the budget and wanted something that can do everything and as close to possibly what a 5D MKII can do, the 7D is the best option. if you want something more specialized, the 5D MK II is your choice. although having said that, what makes us think that the camera manufacturers would stop themselves from developing a much faster and accurate AF for the FF?

note: although this is a bit out of topic, the 645D has even slower AF, but is it at the same level as that of the APS-C and FF cameras?

I bet the 24mp APS-C from Sony will cost less than any FF DSLR.

although the FF prices would surely drop significantly by next year in anticipation of new batch of FF. I would wonder how much Sony, being Sony would price their 24MP APS-C in comparison to the 16MP Pentax and 18MP Canon 7D which are priced at $1500 and $1300 respectively. the closest that I can think of is around $2,000 which is near the present selling mark of the 5D MK II and D700. by the time that Sony releases the A77, the 2 Full Frames would probably be priced at around 2,000 or less.

MM? Who told you so? Did you try it? I did and was surprised, much surprised.
645 AF is K5 AF, better than K7. I dunno if it is competitive with D700 but assuming so without reviews are trying it is bold IMO.
As an MF camera, the 645 AF is first class (compared to MF alternatives) if competitors didn't introduce newer AF modules I'm not aware of.

Yes I tried it. the 645D is not faster than the D700 and 7D either. I forgot to mention FPS as well, so that would be more of a knock-out blow, right?

but the argument is not about that nor is the point but rather asking the question if the D700 or 7D are the better camera than the 645D. the answer would most likely rely on what you need and use a system for. no camera is perfect. one camera fills the need on one area and trumps at that. the other one solves the other. and of course, price is another parameter to be considered.

as far as the K-7 AF is concerned, it is not good for action photography from the beginning. so no question about that.

Yes, that's a valid reason (except that it gives you less DOF, not more )

Lets face it, any new developments in the sensor arena are not a waste and are most certainly interesting.

The 16mp Sony sensor in the D7000 and K-5 has already proven how awesomesauce APS-C sensors can be, so this new rumours 24mp sensor could be just as awesomesauce.

Lets judge it when it arrives .

A 24MP 23.60 x 15.73 mm^2 APSC sensor (1.53 crop) has a pixel pitch of 3.93µm (the K-5 has 4.81µm or 22% more). It requires a lens resolution of 127 lp/mm. That's all not that much more than today.

At only 4µm pixel pitch, a FF camera has 54 MP.

IMHO, that game continues until FF reaches 100MP (2.94µm).
