FMB Posted October 9, 2006 Share #1 Posted October 9, 2006 Advertisement (gone after registration) If the lens is designed to cover the area 24x35 mm., its performance in the smaller area of the sensor is better? Talking about MTFcurves... and effective distortion... Is it a silly question? If it is....excuse me. Francisco. Link to post Share on other sites More sharing options...

sean_reid Posted October 9, 2006 Share #3 Posted October 9, 2006 It's not a silly question. All else being equal, what you say is true. Cheers, Sean Link to post Share on other sites More sharing options...
FMB Posted October 12, 2006 Author Share #4 Posted October 12, 2006 What I mean: The worse zones of the MTF of new Tri-Elmar vill be avoided using this lens with M8? Thank you, Sean. Bye, Francisco Link to post Share on other sites More sharing options...
marknorton Posted October 12, 2006 Share #5 Posted October 12, 2006 "Full Frame" (24*36) occupies an image circle with a diameter of 43.27mm, radius 21.63mm. For the M8 (18*27) , the image circle diameter is 32.45mm, radius 16.22mm. When you look at MTF graphs, any deterioration beyond 16.22mm will not appear in the image.

FMB Posted October 12, 2006 Author Share #6 Posted October 12, 2006 This was the answer I spected. In technical terms one must go carefully and when one buys a Leica lens one must do the same for not investing a lot of money in a disappointing purchase. Thank you Mark. Thinking only of digital M8 the new TriElmar is then more attractive. The same for the new 28/2.8. Using them in analogic cameras could be a subsidiary profit, in spite of knowing that their quality always will be Leitz. Best regards, Francisco.
