I have and use an Elmarit 135 (f/2.8; made in Canada) with an M9. That lens only comes with 'goggles'. The goggles viewfinder masks the finder and shows the 90 mm frame. Really, it works best on an M3 (I used it on my M3, M4 and M6 before getting the M9). The obvious issue is getting the focus right, but it can be done with care even wide open at close distances. I read somewhere that the goggles can be removed for use with a Visoflex, the 'how-to- does not look obvious to me. I purchased this lens used many years ago and I am happy with it, but I do regret having sold a Tele ElmarF/4 (not the Tele Elmar M), it was much lighter and useable, but of course you frame with the tine 135 frame in the finder. The Elmarti is one of the least expensive lenses to buy used, but i would weigh its weight against the one-stop difference between it and the other 135 available.
