That's a lot of rust, Norm!
Such a shame...
I don't think we'll get anywhere with that 12 vs. 14-bit debate. The way the Sigmas render pictures is so far different than the K-5 that it would be impossible to tell how that extra 2 bits factor in.
Originally posted by pinholecam I'm under the impression that the SD1m can take a few makes of lenses via adapters.
You might want to search on that a bit.
I was never convinced by the SD1 and SD1m images compared to the ones from the DPxm series.
Maybe its because the lenses are not as well matched to the sensor since its an interchangeable mount?
The DP cameras probably give you the most technically perfect images you could possibly achieve with the Foveon sensor, but you have to sacrifice some flexibility and creative freedom to achieve that. The two biggest reasons I got the SD1M were wide lenses, and old lenses.
I finally got an M42-SA adapter in the mail yesterday. It wasn't cheap, but it works well. It was the only one I could find with the flange in the back to catch the aperture pin on auto lenses. Otherwise, the pin would scrape the dust guard. Not good. Since Sigma's register distance is 1.5mm shorter than Pentax, you can use adapters with a flange between the lens and the body and still get infinity focus. It's
so much easier than the Pentax ones that have to fit completely inside the mount to work properly.
The list of lenses I can use with the SD1 just got a whole lot bigger.

Takumar again:
You'd think it would be a waste with some of the softer lenses, but the difference goes beyond resolution. Pictures just don't look quite the same as on the K-5, even with that Takumar wide open, when it's quite soft. Whether the different look is better or not is a matter of opinion, and probably depends on the lens. I'll have to dig in to my Soviet collection next.
