Bought an SA-Nikon adaptor from a Japanese who excels in making adaptors for the Sigma SD cameras.
The flange focal length of the Nikon camera is a bit long, so adaptors for Nikkors are difficult to make. As far as I can remember, there is just 2mm for adaptor professionals to manuver when making an adaptor for mounting nikkors onto the SA mount of the Sigma camera body.
The one from this Japanese has resolved such a problem. Infinity is possible for Nikkors on the Sigma camera body. That is good news for few Sigma SD body users are complacent with the use of Sigma lenses on such a legendary camera body.
Members here are mostly with lots of other lenses of superb optical performance. It is a good idea to get an SD15 or SD1M for trying them out on the Foveon sensor. You would be amazed how much fun the sensor can bring you shooting with your superb lenses in good lighting conditions.
The day light was very harsh at the last weekend. The highlight portions easily burst, so I brought down the exposure a little bit to strike a balance. Shots are about one to one half stops underexposed for that.
By the way, I am also tempted to dive in, seeing SD1M's plunge in price. Probably, the plunge is a sign of the coming of the full-frame Foveon.
The price will surely further plunge. Better wait!
To all except for those with the rear rim circumventing the rear-most glass not exceeding a certain height; the manufacturer provides users with a calibrating device to measure the height of the rim. If the rim is too high, it will act on the protecting filter lying beneath the SA mount and break it.
