Originally posted by falconeye I think the SLTA55 and K5 don't have the same sensor. The A55 is 12 bits only, has a few less pixels and sits in a cheaper camera.
More importantly however, SLT technology only shifts SNR curves left on the ISO axis. It doesn't make max. DR worse at all. And what is ISO 80 at K5 should be ISO50 at A55. However, the A55 stops at ISO100 making it loose 1 stop.
that makes sense, thank you!
...if i'm not mistaken the A/D converters sit on the sensor...so would it be cheaper to produce (slightly) lower quality sensors with just 12bit?
i've looked up the (geizhals) prices and it seems that the alpha 55 and the a580 are roughly the same, so it would make sense for them to share their 16mp sensor.

the D7000 will not match it
the d7000 does 14bit(according to dpr), but what about ISO 80?
(edit:which also could tell us something about the sensor...maybe)
editedit: the nikon website says ISO 100 for the d7000, so that means it won't have the kick-ass ISO 80 DR?!?
