  • I had a panagor 28 mm lens with a Ricoh-XR2 SLR (Pentax mount !), and I was very happy with it. So 28 mm ?
  • Thank you, so updating to the latest version of DCU5 is the clue. I renamed a USB-drive to S-SW140 , downloaded the DCU5 software without problems, and, yes, it recognizes the lens and camera well.
  • Thank you for your response. I have firmware 1.16, which is the latest and DCU 4 version 4.40, which is said to be for the K-5. For the DCU 5 version it is said it is for the newer models like K3 ...
  • I just obtained the 16-85 to replace the good old Sigma 17-70 on the K-5. The much smoother autofocus is the most striking difference, corner sharpness and minimal CA at 16 mm the next one. However ...
  • Is is always noise vs sharpness. I don't think a direct comparison will say anything, maybe only for raw processed in exactly the same way. You could look at the tests on dpreview. I would not ...
  • Your picture is already very, very nice ! The O-GPS1 appears to have worked very well (and your tripod too), that is not always the case. To prepare focussing: you can look for infinity at daytime ...
  • I had preferred this specification compared to the DA 16-85, provided the quality is the same, which we can only guess (considering the price tag probably it is at least close). On the other hand, ...
  • On my screen it could be a little bit lighter and I suppose the right-hand part was intended gray; I see a purple cast. I see that in more old lenses. You can correct a bit by changing the white ...
  • You can start to make savings for a new one. The price per picture will be acceptable anyhow.
  • As far as I know: yes you can. Pentax' DCU is highly underrated, by the way.
  • I'm not sure what you mean. I think the usual - and only feasible I suppose - correction is for the lateral CA that increases towards the edges, so near the center this correction has no effect. ...
  • If the resolution can be so obviously improved, this also means that the lens can do better than thought, e.g. in lens tests with a non-shift camera. Of course it will always be the lens/camera ...
  • Thank you for the review. I think you commonly also test bokeh and axial chromatic aberration. Is there a reason you left this out, or you can just spend some words on these aspects ? Thank you in ...
  • 1/1000th of a micron is a nanometer, that is a bit over the top for consumer optics, but you are very correct. With todays measurement tools it is absolutely possible to make and assemble ...
  • Thanks Dean and Klaus. For Dean the reward is the confirmation that he got a fairly good copy. For Klaus: 5% of the lens prize, but only if one gets a good copy ?
  • Interval shooting seems not available combined with pixel shift. Still, you can buy an external shutter release that includes interval shooting. Combined with the maximum shutter speed of 30 ...
  • In NL, and suppose Europe, there are different fees/taxes for goods with value less than EU 45 (0), between EU 45 and EU 700 (2.5 %) and more (21%). This applies to 'packages from individuals', so ...
  • Replied in Pentax K1000
    I suppose you already understood you must buy a Pentax dslr then. Lenses will be ok, but you need additional effort in getting exposure and focus right (despite the help of features like the ...
  • Great, finally, many thanks.
  • Look at this stained glass window. Inside the red parts things appear orange, but in reality this is all deep red. Always use raw, underexpose, minimize Oversaturated reds turn orange in stained ...
