    Summary Digital backs with Technical Camera Lenses
    Problem Some backs may show vignetting, artifacts or lines with certain wide angle lenses.
    Solution It is important to use lenses that produce a wide enough image circle to accomodate the back's CCD.



    Lenses with 90 mm image circle:
    Schneider Kreuznach 47mm XL
    Linos Rodenstock 40mm HR

    Lenses with 70 mm image circle: (will barely cover the area of P 65+/IQ160/IQ180 and not allow for any shift)
    Linos Rodenstock 23mm and 28mm HR

    Lenses with 60 mm Image circle (will barely cover the P 45+ / P 25+)
    Schneider Kreuznach 24 mm XL

    Furthermore the P 65+/IQ160/IQ180/IQ 260/IQ 280/Credo 60/Credo 80 is not recommended with extreme wide non-retro focus lenses like the Schneider Kreuznach 35mm XL and even the Schneider Kreuznack 47 mm XL
    Even though these lenses has more than 70 mm image circle, they are producing a very steep angle incoming light along the edges, occasionally causing thin lines to show up in the image. Note that this can also occur with the P 40+. Sample below:



    Use the table below as a general guide to compatibility with most standard wide angle lenses from Schneider Kreuznach and Rodenstock

    Please review the following compatibillity guideline:



    NOTE:
    IQ250, IQ140 and Credo 40 has equivelent physical sensor size to P40+
    IQ280/180 and IQ260/160 has equivelent physical sensor size as P65+
