Hi Flexers,
You learn something new every day. Thanks to Walter for pointing the
way to the Sigma conversion site. I read all the sections with
interest - the information feeding the "gear-head" in me! The foveon
chip is an interesting variation on what is available from other
manufacturers and I decided to look at the various reviews for the DP
14 and earlier models. Slowly my enthusiasm waned. High ISO low noise
performance did not seem so great. But the real dampener was the 1.7
crop factor. If you want to see the performance of Leica R wide angles
then the Sigma is not for me. For telephotos I can see the advantage
of the crop factor. Going through the example of exchanging the mount
I concluded that it was a much more complex exercise than changing the
bayonets on R lenses and that put me off. So, for me at least, I
concluded that going the Sigma route would not be as satisfying as
going the Leitax Nikon route. Having said that, if a photog's
requirements are for telephoto work in bright light conditions - the
Sigma conversion might work very well for that photog. Again thanks to
Walter for pointing out this alternative and for posting the lovely
photos that show that the conversion works well for him.
Cheers
Howard
