I note K-3 support is scheduled for DxO Pro in January.

Just noticed something rather odd about that DXO review as the conclusion of the article states, "We’ve not yet assessed the resolving power of the sensor."
So to suggest it might be inferior in any way to the opposition might be just a little premature until that assessment has been completed.

John K

Just tried a couple and have to completely agree.

Guess it's what you get used to. With my film cameras I managed perfectly well with just a 49mm thread one on my M lenses. Never needed anything else!

Hi and welcome from not that far from you!

I wonder if it's to do with the general less contrast on a dull day so the photons aren't quite sure what to do with themselves. When its contrasty they have more to do! Simplistic I know but I too had noticed that.
To see real noise in an image look close up at a poster such as those on the wall in tube stations. Viewing one out of the carriage window you couldn't tell what the image is supposed to be at all, all you can see are the coloured dots!

No I didn't today - didn't think to! Just wanted to get a few images from it to make sure it was fine and not need to be returned. Yes I accept there is noise but no worse than from many 100ASA film stocks, possibly less. I don't think it is anything to get worked up about even on the enlarged crop version. Also we don't yet have Adobe support for the K-3 so whether that will make a difference when we do we'll have to see. The camera jpeg looked less noisy than the DNG.

Something else I'll try another day is to compare it against the Sigma 150-500, the manual Pentax K 300 f4 (which I was disappointed with as it seems to suffer badly with CA so was keen to make sure the new DA* doesn't too,) the DA 55-300 and a manual Hoya 300 f5.6 which seems to punch above its weight for the £25 it cost me. Once had a Tamron Adaptall 300 too but that got stolen many years ago! Certainly the DA*300 seems to be a fine lens as you have proved on numerous occasions and should pair well with a DA*200mm which I've had for a while.

Can you expand on "noise in good light is different to noise in low light?" Cheers!

John K

There are no electrical contacts between an M42 lens and the camera so it would seem the camera thinks the image is not in focus. Perhaps what you are focussing on doesn't have much contrast for it to work.

John K

So far:
DA 14mm f2.8 (for night/indoor shots)
DA 40mm f2.8 XS (convenient to leave on the camera)
DA 17-70mm (useful range)
And as you suggest, the DA 35mm f2.4 is quite convenient.
I've not tried manual lenses on the K-01 yet but didn't manage too well with the Q using focus peaking.
