The dirt on the flange might simply be from the plastic cap.

I have bought these on ebay: https://www.ebay.com/itm/233367396779 Took one month to arrive though...

I personally prefer version IV (or III), but any 50 Summicron would be a perfect M lens to start, IMHO.

50mm f/2 Summicron-M

I have never been to Greenland in August but was cruising and hiking in the Svalbard archipelago in that same period, the photographic environment should be very similar, especially if you travel toward North. I believe that the lenses that have been mentioned here for Iceland would also fit in Greenland. Expect to meet a very rich and diverse wildlife (birds, seals, polar bears, whales). I had a 100-400mm with me and used it a lot, mainly for shots from the boat or zodiac. If I will go again in the future I would bring a 500mm.

I hereby thank again Jeroen for patience and guidance to find a solution for my problem. In case anybody in the future will need this information I am reporting it below. Replace the receiver 10 din plug for a 8 din plug and connect the cables as follows: White from 1 to1 Pink from 2 to2 Grey from 3 to 3 (+) Brown from 7 to 4 (focus) Yellow from 6 to 6 (-) Isolate the blue and green wires, they are not used.

In Icelandic summer you will meet many interesting birds while you drive/travel, it is a good idea to always keep a long lens mounted and ready to shot.

Unfortunately (despite additional suggestions received in private from Jeroem) I am still not able to get the remote 37988 working with the Pradovit CA 2502. First I have tried removing connections for the resistor (blue and green cables) from the receiver 10 pin plug. On a second attempt I have replaced the 10 pin plug with a 8 pin plug following the scheme in the pdf above. I have checked the 9 volt battery in the remote and all the connections, with no success. Any additional suggestions would be very welcome.

Thank you so much Jeroen. It will take a while for me to translate and understand the document in German (with hand notes in a language that is maybe Dutch?), I will very likely be back soon with more specific questions.

Hello, I have a Pradovit CA 2502 that is working flawlessly. Looking for a remote to be used with it I have found the Leitz Infrarot-Fernbedienung PCM 37 988, which according to its instruction leaflet is compatible with the Pradovit CA 2502 starting from serial No. 145758. Unfortunately, my CA 2502 bears serial No. 140070 and when I plug the receiver of the remote in the 14-pin socket of the projector the lamp switches off and no remote control is possible... Does anybody know what kind of modification was introduced in CA 2502 from serial No. 145758 and if that modification might be retrofitted to previous samples? Or anybody has a service manual for Pradovit CA 2502 in pdf for my perusal as to find the above information? Thank you very much in advance for any reply.

The book authors are Bruce Fraser, Chris Murphy and Fred Bunting.

I have sold my M240 to buy a used SL body, almost at the same price, and am very glad I have done that. But only because I also own a M9-P...😉

See here:

I have tested the following Canon EF lenses on the SL (firmware 3.3) with the Novoflex adapter: Canon 500mm f/4L IS II: AF work but slow and being recognized as 24-105 f/4 24-85mm f/3.5-4.5: AF work. OK speed 15-85mm f/3.5-5.6 IS EF-S: AF work. OK speed. But is being recognized as 70-300 DO 60mm f/2.8 Macro EF-S: AF work. OK speed. But is being recognized as 400 f/2.8 I also confirm that the 70-200mm f/2.8L IS II is working with OK speed.

Thanks again. By the way, I have seen that according to Put's Leica Compendium (Third Edition) WATE serials start from 3995091, i.e. lower than Leica Wiki, my friend's lens is above that number.
