A bit worrying, especially for me, as my camera spends a lot of time above 20000 feet. Saying that, I have had my K7 with me for over 1000 hours flying time, and I have never seen any problems whatsoever with it. I have printed larger than A3 without noticing any black lines, as he says in the video, and never noticed anything in PP.

At work get monitored for gamma ray exposure, by route flown and altitude (flying over the poles produces the highest doses), and I apparently get a lot less than someone who lives in Aderdeen, where a lot of buildings are built from granite. So if gamma rays are a problem for cameras, then living in Aberdeen is worse for your camera than flying.

This has probably wrecked my chances of selling my K7 on the forum though..thanks John!

I've never had a problem on ebay, got a few bargains and have generally been very happy with it. It pays to read the ad properly though, I have seen a few people selling pictures of something rather than the real thing. Ebay should ban them.

I can't understand why some people pay over the top, but I am not complaining, I sold my Olympus E520 with two lenses for 10 quid more than I paid for it all, after a years use!

Nice shots, I especially like #'s 7 and 8.

Coincidentally, a friend of mine was flying the vampire in #2 (jammy b#$ger)

Very nice, I especially like the grasshopper and the second fly.

I wish I could get the macro out, and was hoping that the wonderful garden Jackie has made from sratch here in Doha would attract some bugs, but alas, it seems there's no bugs here save the occassional mosquito

Wow, looks like an alien landscape! The strange building just adds to that, in fact,the image reminds me for some reason of the stories of Ursula K Le Guin. Nicely done, can't wait to try out the IR stuff myself!

Here's a review of the lens link, tested on a Minolta 35mm camera. it compares it to two primes, the 200mm f/2.8 MD Rokkor-X and the 300mm f/4.5 MD Rokkor-X. It seems to do pretty well compared to these lenses, but I don't know anything about how good the comparison prime lenses are.

It can fire before a sound? If it can detect something before it's happened, our notions of time are evidently wrong

The colour one is very interesting; I don't think you've quite nailed the colour conversion but I would love to see more experimentation along the same lines. Would it be worth fiddling with the WB, or perhaps the colour balance, after the conversion?
