Ok folks, Ive got a little bit of a dilemma. Im in the market for a 90mm lens to compliment my Bessa R3M. At my local camera shop, they have for sale a used Leica 90mm F2 Summicron (made in Canada) for $399. The lens looks very well used but is perfectly functional and has a 90 day warranty so I have faith the lens will work just fine. Ive purchased used equipment from this shop before and they are very trustworthy. I also notice over at Camera Quest they have the Voigtlander 90mm f3.5 APO Lanthar. Adding in the cost of a screw mount adapter it would come out to be exactly $399 as well for a brand new lens. Now, Ive never held the Lanthar lens in my hand, but from the pictures it seems quite a bit shorter than the Summicron which would be a plus for me. However, the Summicron is the faster lens. According to the Camera Quest website, the Lanthar has a minimum focus distance of one meter. Does anyone know if the Summicron is the same? The minimum focus distance is a big selling point for me, probably even more important than the maximum aperture. Also, has anyone done a direct comparison between the two for image quality? Im very happy with the 40mm Voigtlander lens I own so I trust the quality of their lenses and of course Leica is legendary in that regard, but is there a huge noticeable difference? Heck, in my experience sometimes the "off brands" can even be of better quality but people get so stuck on the cool factor of more popular stuff they simply won't admit it. Obviously Im the one who needs to make the ultimate decision here, but I value the opinions of people on this board and would love to hear your thoughts.
