    4x5 TP Anyone?

    Dunno which forum section this might belong in, but I figured people would see it here. Pricey, I know, but probably worth it to someone.

    Help is on the way. See www.technicalpan.com. I've used this film and it is as advertised. Shot it in 4x5, but the resolution is much too high for meaningful results in LF images. (900 lp/mm at 1000:1---Diffration limit at f22 is 61 lp/mm-overkill)

    Don't know where you got the 61 lp/mm. Experimentally obtained value is more like 14 for perfect 100 mm lens, agrees with theoretical.

    Do you know what MF(120, 220) and LF sizes it will be available in and when they will be on the market, cost, etc?
