Personally, I may consider getting an a77 if I find its AF is really needed for my shooting. Otherwise, there are much better choices.

But the AF performance is very important thing to consider.

After DP Review's A77 review, I started to use fixed iso, trying to use not beyond 400

Just for the kicks

A half-res crop from some DPR Nex7 sample found in their a77 review. The full image screen dimensions would correspond to an about A2 size. Easily printable to A3.

And that's ISO12800... No sophisticated processing, just Lr3.5 with pretty standard settings I use for higher ISO.

Not much to complain about there!

That's not bad at all for PP'd 12800.

I'd be quite interested in a side-by-side of same with the a77, which begs the question;

What are your 'pretty stanadard settings' for treating higher ISO in LR3.5?

Thanks

OK, the a77 sample with the same exact processing and the NR/sharpening used.

Wow, that was quick - thank you!

I normally don't do a lot of peeping at this level but......

The NEX-7 = an over all better result, as one would expect. I'd add; noticeably less blotchy and less chroma noise.

It would be interesting to see these as prints side by side - I will try and do that one myself sometime over the weekend.

But, I note more detail in the a77 rendition e.g. in the yellow leaves in the bottom left hand corner, just below the squash?

Thank you also for those settings, I will geve them a try.

Interesting that you dial in Radius = 3.0, I usually go the other way to = .8.

Thanks again

Those samples were obviously focused slightly differently. And given the much higher noise, the NR also fails to smooth the a77 image to the Nex7 levels. The detail was tuned for the Nex, the 77 just received the same settings pasted.

Sharpening at 3.0 radius is actually a microcontrast adjustment that really helps at high ISO. Real sharpening should come upon that, e.g. exporting to TIFF and applying some low radius sharpening then. This time I simply used the 'sharpen for screen' setting at Lr export.

And btw, I changed the SonyModelID of the Nex7 files to the '287' a77 value using the exiftool. So all the 'under the hood' processing in Lr is exactly the same for those samples here.

Hi

Just thought that I would let you know that your settings are making a marked improvement to my a77 on screen images - and even on PP for some lower (100) ISO RAWs.

Thank you...(and so, the agorabasta a700 settings legend - lives on )
