Dear Forum, just new – since some months - in this circle, I feel like at home, because there are so many experienced and friendly people in this forum. Therefore, I hope, anyone can perhaps help me to find a suitable actual Leica M lens for infrared imaging with a Leica M8 ! Principally, IR with the M8 works well with some restriction, perhaps mostly coming from the lenses. I see only few problems with the Leica Apo 2/75, which I bought a short time ago. IR-imaging was quite good with very old screwlenses Elmar 3,5/35 and 3,5/50. I tested a Voigtländer Nokton 1,2/35 mm asph. , which had such a big focus shift in Infrared, that I could not do good IR-work at all. With Zeiss-Lenses 4/18 and 2,8/25, IR-imaging works, because they have an IR-marker on the distance ring, but they are not my overall favorites. Therefore: which actual Leica lens between 18 and 50 mm focal length may be suitable for IR-imaging with the M8 ? The lenses are too expensive or it would take too much time to test them all, therefore I hope for helpful ideas. Thanks in advance, Joerg
Hi. Sorry, I don't mean to re-hash old discussions. I have read numerous threads on 21mm Elmarit vs. 24mm Elmarit issue (as well as 21mm Elmarit vs. 21mm Summilux issue) but just cannot come to a conclusion on the matter. I am looking for a wide angle lens to add to my arsenal of 50mm Lux and 35mm Cron both of which I am very happy with (but I just feel the need to go wide at certain times). I have used the 21mm Elmarit (both pre-asph and asph) and am aware of the issues of loss of shapness and dark edges when wide open as well as some distortions but still think it is a neat lens (actually prefer the pre-asph). I have read on this forum and at other places that 24mm Elmarit is a "dream" and that it is optically superior. What makes the 24mm such a "dream"? I see that the 24mm usually commands a premium over the 21mm and wonder if the price reflects this sentiment. Is the 24mm such a superior lens that I will just be missing out a lot if I "settle" with the 21mm? Is the combination of focal lengths (as mentioned above) a consideration as well? I have also considered the Voigtlander Cosina 21mm/4.0 due to its size and cost advantage but have read that it is not good for the M9 given its rear nodal point being too close to the sensor. Pleaes help me with some feedback. Thank you for your help.
