John - "I think persistently what you are not seeing is the improvement of clarity in detail. That's clearly visible to me and to others as well. I see it in the images." This might be true for original full-size images although, even then, it seems to me that any differences are being greatly ex...

K-5IIs - more discussion
It sometimes seems to me that my contributions to this forum are just as invisible as the differences between the comparison images posted here. I'll try again by quoting from the dpreview page that I linked to in my last post: "In theory, a sensor without an AA filter, when coupled with a 'perfe...

"... vertical and horizontal detail is accurately described (by the original K-5) up to around 2800LPH, with some line detail surviving up to, and even slightly beyond Nyquist." If they think you can go beyond the Nyquist limit of a sampling system then they don't know what they are talking abou...

Yes, Andrew that is a valid interpretation of my point! I am concerned that we often hear someone saying something like : 'these shots have been posted with absolutely no editing / alteration applied - what do you think of the differences?' This raises some questions that we don't hear much - na...

Rumoured announcement of several new DSLRs
Hmmmmm. Interesting. Probable? not likely Possible? Maybe. They to serious increase capacity at the factories to cope. This may already be there, we don't know. Now what could take place if true. Entry Level DSLR under the K30. Lets call it the K300. 16MP sensor, no sealing. Upper le...

I got Moire
After a couple of days taking a few shots with my new K-5IIs I think I've seen aliasing on both days. The main gain for me over the K-5 is the autofocus accuracy. The added sharpness from losing the AA filter is a bonus, but only if I don't get too many aliasing duds. Hopefully over time I'll not...

2nd set of photos more unexpected than the first, and so more disappointing in a way, but all cameras without an AA filter will be prone to the effect. So far as I can tell from reports only the Foveon sensor escapes the problem -- because of course it avoids the neat repetition of the Bayer patter...

That stuff on the K5 body looks like chroma noise. What ISO were you using? If you got rid of it on feathers using the chroma filter than that was probably chroma noise too.

Final advice before the purchase day.
My 17-70 is an old model, I bought it when they were first released. The SDM has never been a problem on it, or any other 17-70 that I have heard of. It was a problem on some older 50-135* lenses, but not all - mine is an old one, and again never had a problem with that either. Don't bother w...

Don't bother with a protector filter of any sort. A circular polariser yes, worth buying, but a protector or haze filter no. Have you ever worked with a camera in a maritime environment? I have, and have seen what salt splashes can do to lenses.

Final advice before the purchase day.
A circular polariser yes, worth buying, but a protector or haze filter no. Would you use a UV filter (and a rain jacket) to protect the lens from adverse weather or spray from waterfalls? I bought both some time back, but they rarely see the light of day. What do others do to protect non-WR lens...

Well thats the purchase done, thanks again for your help and advice. Just spoke to a very helpful gentlemen at SRS and a K5-IIs with the 135 lens is on its way along with a kenko filter. Had another bill this month so the other 55-300 will need to wait till next month.

Maybe light at the end of the tunnel?
Given the comparisons between the ASPC D7100 & FF D600 it seems the FF argument has just about reached 100% pointlessness. Slight differences at very high ISO? Forget it. 24mp AA filter less in a K5 body would do nicely, then again I don't want anymore storage memory used of more slowing down of ...

Bit depth does not automatically translate into DR, but people use the terms as if they're interchangeable. For instance the Kx easily beat the K7s DR. Both 12 bit. And the K30 has very similar DR to the K5, at equal ISO. 12 vs 14 bit. I think the difference between 12 and 14 bit is overplayed. It s...
