So let me get this straight, the only difference between the 850 and 900 is 3fps Vs 5fps????

Also smaller viewfinder.

Of course the street price is key, but the manufacturer list price is within expectations. If that translates appropriately to street prices I'm likely to get one :)

I have enough FF lenses on Sony that I can get body only without forking out for a ton of new lenses, although I will want to upgrade at some point. Really looking forward to some seriously shallow DoF fun that you just don't get on smaller sensors.

I was thinking of getting the A900, but now with the A850 might be a better upgrade, about the price difference is still a question of time, if the A850 expected sales don't turn up they'll for sure reduce it. So maybe a 4 to 6 month wait would be wise. If I ever do get the A850 I'll for sure get a nice CZ lens like the SAL-2470Z, but I'll need some serious photo knowledge before getting it, so keep commenting on my posted photos and tell me how incredible they are. :lol:

Again, I'm sure my wife won't tell the difference between the A350 and A850, cause she'll never understand why I need to spend some much more for a little difference. (because the A350 is still a great camera) thanx for agreeing.

Thank you Bob for the info share... thumbs up buddy

Amazing value,great work Sony! :)
And if 5MKII + 24-70mm = A850 + 24-70mm,then Sony has really an edge here,because the Zeiss lens it's a bit better and also,you get IS with this lens & any other lens you attach.

Nice move, and this should shake up the DSLR market and make things interesting.

Is the sensor the same as in the A900?
Ah yes: "the α850 shares the same 24.6 megapixel sensor and virtually all features of the flagship DSLR-α900".
And I thought there was some "backlight" sensor coming up from Sony with increased sensitivity...

Having read the a500/550 announcement it's funny to see them advertise ISOs up to 12800 whereas the A850 stays at max ISO 6400...
The smaller siblings also have the added feature of in-camera HDRs!

The working assumption is they cost reduced the A900 by using a lower quality viewfinder, maybe cheaper/slower mirror assembly, and possibly reduced processing power in some form. It is assumed the sensor is unchanged.

The Exmor R backlit sensors are the big thing in compacts. I haven't looked into it in detail myself, but the understanding is it only provides significant advantages at higher pixel densities like those in compacts. It reduces the impact of in chip wiring on the light loss. The bigger photosites on DSLR sized sensors are not as obstructed in comparison.

I do wonder if the basic technology in the A5xx is improved since A700/A900. The A500 sensor seems at first glance to be the same as A700, but the A550 is a new sensor as far as we know. Although the 14MP sounds same as the A350, that was CCD whereas the A550 is CMOS. They have improved the noise reduction processing in camera so that may be why they're able to be more generous on the high ISO range on the A5xx range where the A850 is left with the same basic functionality as the older A900.

it is great value for most of photographer/amateur-pro out there.
This camera is very similar to A900. If i'm not shooting sports, then this A850 is good enough and I'll save $650

Sony, what is it exactly you are doing?

Any studio or landscape photographer doesn't need high FPS, so they'll get the a850.

Sports wont use either.

Wedding Photographers will get a 850 if any, although will probably just go canon/nikon for the better high ISO performance and FPS.

If they made it a heck lot cheaper and 16MP, sure winner. Nice moden competiton to the D700 (and new 7D?)

Who ever does their research for what the market needs - needs a good slap. Well done Sony. 8)

What Sony are doing is pushing FF lower down. Kinda like when the original Canon 5D came out. They're not directly targeting existing FF cameras, but carving out a new bit of space. The high speed side, for the moment, is left to the A550. As was already pointed out it also somehow manages a higher maximum ISO, even if it remains to be seen what it will be like at those settings... I'd guess it'll be like the 50D ISO12800 setting. Yes, it is there, but you really don't want to use it.

Seems the info I posted earlier was pretty accurate. :) And the A850 turns out to be a nice camera indeed, at a great price. Not that I'd buy it, but I can certainly see why others would.

Now where's that 500mm?
