Looks like a very nice piece of kit (though to be fair to the A55 it's not in the same class or price bracket).

If we're REALLY lucky this might spark another round of 'What the A77 MUST do otherwise I'll sell every Sony product I've ever bought' comments

Pentax said during photokina that it is a Sony sensor.

Whoa.. almost 14 eV? Crazy..

It beats Fuji S5, D3X .. probably every medium format sensor. :D Thats insane for APS-C. Someone give Pentax full-frame FFS. :D

Though, if Sony will be able to do same or better for A77 or sucessor of A700.. well, we can see really interesting things happen.

But, it doesnt beat A900 in few aspects. Its not FF and it doesnt have its color accuracy (A900 has as far as I know highest metamerism index from all and thats that magic which makes those colors..).

Pentax readily admitted during Photokina that it comes with a Sony sensor. They went out of their way to state that "Sony makes great sensors".....unlike Nikon who typically try to hide that, when they use Sony sensors.

As with most reviews, I would take this with a grain of salt. It's gonna be a little harder than that to convince me that the K-5 has a higher DR than the D3x or S5.

The Panasonic GH2 results also came in this moring, and the GH1 scores lower than the GH1. Panasonic just changed its sensitivity ratings, making people compare results at different real sensitivities.

Sony is doing something right with their sensors these days. The Pentax forums pretty much falls in line with the DxO K-5 results.

Hmm I think the new Sony sensor are probably a huge leap forward compared to what was available before. The fact that the a55 scores very well while it's losing light with the SLT design, was already impressive. And this is even more, is this maybe the first generation of CMOS sensors for DSLRs that has the electronics on the backside instead of blocking light for the sensor?


Does show that Sony Alpha needs to improve, the fact that (much) more expensive Nikons were doing better than Sony with Sony sensors was something that could be put down to the price of the Nikons. But if Pentax starts to get more from a Sony sensor than Sony does...

I am nterested to see what the A580 and Nikon D7000 end up scoring, since I think they both are using the same sensor as well. And then see if Sony can better it with whatever A77 sensor and FF sensor they have in the works.

Well, to be fair, the only category it beats the A900 in is dynamic range and the arbitrary "overall score". This is if you look at the print (i.e. final output) tab, which is really the only thing that matters and ignore the "smoothed" ISO 3200+ values, which presumably means that there is in camera noise reduction employed, which could be employed in post processing for the A900 to achieve better results.

Still, it's very impressive for an APS-C camera and the dynamic range is very impressive for any camera.

I'm thinking five things, all good.

i. Nikon FF are pretty scared by this.
ii. Canon are totally scared by this.
iii. I can't wait to see the A580 scores
iv. The A77 should be a cracking camera
v. A FF sensor with this technology would be crazy good.

But they really should offer an OVF-based 7 series as well.

Is the higher DR thanks to the 14-bit ADC?
