timothy_blomquist1 Posted October 26, 2004 Share Posted October 26, 2004 What is the quick formula to compare 6x6 and 6x7 format lenses withtheir 35mm equivalents? ThanksTimothy Blomquist Link to comment Share on other sites More sharing options...
yeow_teng_kuah Posted October 26, 2004 Share Posted October 26, 2004 A quick rough formula :- <br><br> 6 x 4.5 = (X) / 0.66 (Where X = 35mm lens size) <br> 6 x 6 = (X) / 0.62 <br> 6 x 7 = (X) / 0.45 <br> Link to comment Share on other sites More sharing options...
db1 Posted October 27, 2004 Share Posted October 27, 2004 If you check the mamiya website, the following happens for the Mamiya 7II: 43mm = 21mm 50mm = 25mm 65mm = 32mm 80mm = 39mm 150mm = 71mm Link to comment Share on other sites More sharing options...
