Hi, I use the 19 Elmarit 2nd version and a 'professional' modified the lens for me. No problem although I found it a bit scary to do it myself. In my opinion it is a better and more safe option to shave just a little bit from the protruding ring of the rear lens barrel ( about 1 mm - 1,5 mm, only just a small part of the ring) then shaving the mirror. With the R 60 macro , the 19mm is the most used lens on my 5dMkll. ( Ok; also the Elmarit 28mm and for fast work some Canon lenses) Only focussing with the 19 is almost impossible. The ordered Brightscreen is not much for a help. Live View is great, but not always practical. AND: the Elmarit need a little adjustment for infinity after installing the Leitax adapter. best Herman ------ Unsubscribe or change to/from Digest Mode at: http://www.lrflex.furnfeather.net/ Archives are at: //www.freelists.org/archives/leicareflex/
