    Re: Shen-Hao TFC810A

    This is a non-folding camera with a maximum bellows extension of 450mm, not a good choice for close portrait work with longer-than-normal focal lengths. It really is optimized for general scenic...

    Re: Wide angle lenses for 8x10

    FWIW, the 120 Nikkor SW is actually specified by the manufacturer to cover 8x10, just. (Nikon says 312mm at f/22.) With the 120 and 121 SA the specified image circle at f/22 is a bit short of 8x10,...

    Re: Wide angle lenses for 8x10

    I have an 8x10 box camera built around the 120mm Super-Angulon. Stop way down - I'll usually work at f/45 or f/64 - and it can more or less eke out 8x10, especially if your point of focus is short...

    Re: A new lens cleaning experience

    Per the MSDS, the ingredients of the basic Simple Green product ("All-Purpose Cleaner") are:

  10. Re: Does anyone on here use a lightweight matte inkjet paper?

    Yes! I've used UPPPM as a proof paper for Epson Hot Press Natural. They're not identical in behavior, but the UPPPM gets me close enough to save a lot of testing on the more expensive paper.
