http://www.isl.co.jp/SILKYPIX/english/products/This could be interesting for those interested in checking whether the quality of the first Mamiya jpg samples was a conserquence of the Mamiya raw converter being used.
Silkypix has received extremely positive reviews from Kodak SLR/n users, and it might be one of the best available converters for images taken without an AA filter.
I have never tried it personnally.
