martin_czermak Posted June 6, 2004 Share Posted June 6, 2004 i have the chance to buy a nikkor t-ed 8/360 lens. i would use it on my linhof super technika V 6x9. now my question: can i use this lens without any limitations in focusing? the reason why i'm asking is, i have seen that the focal flange distance is "only" 261mm. the max. bellows extension of my super technika is 300mm. are 40mm focusing range enough for shots with a minimum distance of +15m? i will take no macros and portraits.

michael_briggs2 Posted June 6, 2004 Share Posted June 6, 2004 With the figures you give for the lens and the camera, a 300 mm extension for the Nikkor-T is equivalent to a 300 + (360 - 261) = 399 mm extension for a regular lens. From the basic equation of optics, 1/d_o + 1/d_i = 1/f, with di = 399 mm and f = 360 mm, the distance to the object is d_o = 3680 mm. So you should be able to focus to objects as close as about 3.7 meters. Link to comment Share on other sites More sharing options...
