Hi all I am looking for a 500mm or 400mm tele to experiment and learn to take bird and wildlife photo's. Of course you know by now i am not an expert ;-) You also know i will be using the lens with Leitax and (hopefully) in the future with a D700. The leica miror lens can easily be transformed into a Leitax, the 560mm as well but not all the 400mm's (it depends on the serial number, it must be an old lens) But i like to learn and experiment. The technique for me will be a real challenge, but that will be the case anyway. Would it be harder for me to learn with the big lenses or with the miror lens ? THIS kind of information i find very exciting : http://forum.getdpi.com/forum/showthread.php?th87 But i did see some pictures on Flickr that are a lot less exciting ! Doug explains a lot about the long lenses on his site and i found some explanations by his hand on other fora. But i did not find so much on the mirror lenses. I find the compact size and weight a real plus, so i wonder ... If the miror lens is not an option, i will go for the 400mm/560mm solution i think. Of course i know by now about the usual stuff (donuts f/8 etcetera) in general terms, but what does that mean in practice ? Just curious : who has real experience with the Leica 500mm f/8 MR-Telyt-R and how does it compare to other leica options for me. To see some pictures would be nice too.
