    WOW! Looks like a fish eye lens. And talk about long exposure photography! Amazing photo! Cannon or Phase One?

    Thanks! Canon 5DmkIII + 15mm f2.8 Fisheye. I could possibly do this with our old Phase One P45+ & 28mm f4.5, but not with our new IQ140. It sucks with long exposure.

    Too much noise with the IQ140 after 1 hour? I would have thought the huge Medium format sensor would be superior to any Full Frame but I think it rounds down to Pixel density. Completely different class of camera comparing to consumer grade APS-C camera's but the theory is the same. I suppose the problem in a higher pixel density of an 80 vs 40 Megepixel digital back introduces more noise during long exposure. I myself am sticking to APS-C trying to decide on my next APS-C body and concerned that the newer 24Megapixel APS-C camera's will cause poor long exposure images vs the proven 16MP Nikon 7000.

    Or go to film and forget about noise and pixel densities. :-) Check out my 24 hour and longer exposures. http://RusselKwan.com - look for the "Time's Arrow" gallery. :-)

    Jason: No, the IQ140 has too much noise after 2 minutes! LOL. It has nothing to do with pixel density. The IQ140 has more or less equal pixel density compared to a Canon 5DmkIII but still has horrible high ISO and long exposure performance. They're not built for that kind of usage, really. The P45+ sensor was IIRC made by Kodak and could easily handle 90 minute exposures but the new sensors are made by Dalsa. The Kodak sensors performed much better than the newer sensors with long exosure. I think the new IQ2 series sensors do long exposures well. We will be getting rid of the IQ140 soon and getting an IQ260 soon.
