Principally yes, of course, not sure what artefacts this gives. In photoshop (elements) there is a feature to remove blur due to camera movement, that should work about the same, though I never ...

Looks like either the sensor or the electronics are reaching the end of their life; some shortcut and/or loose contacts. I don't think the scientific investigation of this effects may be worth the ...

Ah, not compatible with the K5, thank you Pentax, no point to plan anything.

The DA 50/1.8 is about 1/10th of that price and is optically fine. Not optimized for full frame, but still.. Why not make something mechanically better and full-frame compatible for some EU 500 ? ...

Although the software is bashed all-over, I have no problems with DCU. My only complaint is the highlight recovery that hardly works, unfortunately this is the same in Silkypix (I may do something ...

Nothing wrong with the camera, even today, just it starts struggling at ISO 1600 already. The 50-200 lens has compromises due to its size and prize, especially at 50 mm it seems to be not so good, ...

It's the supposed law of supply and demand than enables such practices. You see similar practices for e.g. scientists and musicians: you can publish your scientific work if you pay for the...

I'm a happy Pentax user, and with the stabilisation you have a point, just it crossed my mind. So maybe move to Sony just for the lens choice ?

An equiangular tetragonal format. The Rolleiflex was very popular, using the 6 x 6 cm film format, in which you could compose your favourite portrait or landscape format after the picture was taken.

Maybe the coating of the Pentax is somewhat better . I think that if your really like Pentax lenses, you are cheaper off buying a somewhat more expensive Nikon body (same Sony sensor, right ?) and ...

Maybe, but for a realistic view you must bring your eye close to the screen, and then the car on the left is even more unnatural in the fisheye. With a bit googling I found nothing wrong on the ...

I suppose a fish-eye combined with an astrotracer will not work at all, probably it hardly improves anything over not using it. Maybe if you just point the camera to the polar star, but also ...

Interesting, but wide angles are the least challenging for the astrotracer. With 100, 200, 300 mm lenses the accuracy really counts, and usually limits the useful exposure time to some 20 seconds, ...

The low shutter noise was a major reason to purchase the K5 (coming from the noisy K100D). What about the shutter noise of the KP compared to the K5iis ?

No, you are not a troll, but not a beginner either, but still a "Pentax lens beginner", to be read as one concept, potentially, so a misunderstanding is easily born. The adjustable anti-aliasing ...

Really beautiful, especially the colours and dynamic range. But you say 'sorry low res', while the pixel shift is about increasing the resolution. Can we get a high-resolution version as well, or ...

You can get some idea of a comparison from the photozone website. You can see how the Sigma and Tamron lenses compare to the 'native' Pentax lenses for some Pentax systems and how the same Sigma ...

I would not call pictures 3 and 4 'front' or 'back' focus, but just he appears to have focussed on a region different from what you wanted. With such an aperture/focal length you really challenge ...

35 mm makes little difference, you better go to 30 (Sigma) or 31 (Pentax) for a more natural angle. For more flexibility you may consider the 16-85, keeping the 43 mm for lower light cases. What is ...

I find the differences at least as intriguing as the similarities. The lights next to the water that are on at the left side of the second photo, and at the right side of the first. The trees/sky...
