Thanks guys!

Bump....

A forum member has come up with a Pentax 50mm, I'm still looking for other focal lengths. No one else with some faulty old primes they want to get rid of?

Thanks all! I was surprised how well they came out, I must try this more often! Most previous attempts have been either blurred or very noisy.

They were taken through the front window, Paul.

The company in the UK I contacted (Protech, the one mentioned in this weeks AP) are not doing the K5 yet, unfortunately, though will be soon as they apparently have had load of enquiries. I may get it done in the States by Kolari, who charge $250.

Waiting for a quote, will let you know when I get it....

I guess I will wait and see if a FF Pentax comes out. Meanwhile I may just get the AA filter removed from my K5.....cheaper than buying a K5IIs. My IR Sony has exactly the same sensor, and the AA filter on that was removed during the IR conversion. The Sony definitely resolves more detail.

I took these last night approaching Buenos Aires, from about 15000 feet. Both taken at ISO 1600, with the Sigma 24mm Super-Wide II f2.8 wide open.

I'd like to know if I could get another couple of stops of ISO if I bought a K5IIs, though Sod's law says the day I buy one will be the day Pentax announce a FF camera....

I'll have to see if my digital edition is ready for download. I'm still vacillating on whether to get a K5IIs or wait and see if the long-rumoured FF camera is going to appear...

Does anyone have any links to noise comparisons between the K5 and K5IIs BTW? I could do with a couple of extra stops of usable ISO more than anything.

Lovely shots, number 1 the standout for me too. I like the look of the tripod thingy, think I'll get one.

Needs to be prime lenses, infinity focus in IR varies a huge amount through the zoom range. I don't want the bulk of a zoom stuck at one focal length.

I've tried that with my smc-A 50mm f1.4 twice, John, and both times must have nudged it a touch applying the tape, and the focus was off. I'll try again though. Of course it then means the lens is not usable on my K5 until I remove the tape, which is why I'd prefer to have two of each lens. As I only need infinity focus I thought a cheap option would be to buy some damaged lenses and permanently modify them.
