The bottom line is that I yearn for the control laypout of the a77 but I do shoot a lot of action photography and wildlife that sometimes requires ISO1600-3200 when using long lenses.
Has anyone moved up to a77 from a700 and can comment on high ISO ? I don't honestly think I will want to start messing about downsampling, etc, so straight out of camera, what is ISO 1600-3200 like versus the a700? I know I can use the DPR compare tool but I don't like looking at sterile lab test charts - I prefer real world examples where possible.
I have read rather varying reviews and thoughts - some say a77 is miles better IQ than a700 even at high ISO, some say a77 ISO 3200 is very useable, some say a77 needs to be used below ISO 800. It's hard to find any consensus. And I know David K got rid of his a77 because of being unhappy about the noise performance (I'm sure DK will correct me if I am wrong).
Some say they shoot the a77 at 12MP is using high ISO - does that produce better images than a700 ?
There's no way I can afford an a99 by the way, but I guess a D800 might be an option, but I don't honestly want to switch systems. High ISO on my a57 is nice, but I miss having dual control dials a lot, and I think my lenses would benefit from micro AF adjust as offered on the a77.
But classiccameras, is this not the segment where Sony leads CAN/NIK with their NEX range? (If I understand CSC correctly to mean Compact System Camera). With the growing E-mount range of lenses and "free" access provided for just about every SLR and DSLR lens in the market, Sony have a great advantage over CAN/NIK and can become the dominant force in this market. Just imagine the additional advantage of turning the RX1 into a system camera with interchangeable lenses and providing mount adaptors to allow third party lenses use. Go out and take A99/D600 quality shots & video with a smaller package half the weight. I would be surprised if this is not part of Sony's future camera strategy. Per SAR they have abandoned FF prototypes using 36 Mp sensor. I see them going full speed ahead on continued development of APS-C NEX and a FF NEX system based on the RX1 idea. Only way to really get into FF against CAN/NIK. My DSLR system around A550/580 is being used less and less. I now have a small bag containing one NEX-6 with 16-50 Pancake, one NEX-5N with 24mm Pancake & W/A converter and one 55-210 E-mount zoom. That's it and amazingly small and light for what it can do. 18 to 315mm range (36mm speak) & two cameras in one small pack. For everyday use I carry an RX100 on my belt. Barely noticable.CSC'a are the growing sector in the British market and there are already some well known pro's using them. They are now the biggest sector of the far East markets including Japan.

Right on - A99 delivers 2/3rds of a stop less exposure at higher ISOs, even after compensating for the mirror, compared to Nikon or Canon, to the sensor. It completely distorts the noise assessment but also doesn't improve the images.

However the A99 wins in a big way in low light, even the NEX-5N is far better. I have all three so I don't really need to worry, but I am rather short of funds as a result. I'm just very unwilling to lose APS-C and the lenses which go with it.
I still use the A700 for my studio product pix. There's no comparison with the A77 because if you use the A77 at 3200, you can reduce the file size. There's not much ultimate difference but the A77 can do multi shot noise reduction for JPEGs etc.
