I have a sweet Voigltander R3m that came with a 40mm f1.4 Nokton Classic lens- which someone somewhere along the line suggested was paired specifically with that camera- as though the two were made for one another. Along the way I've picked up a 50mm lens as well, b/c isn't 50mm the classic focal length for a 35mm format camera? But the 40mm & 50mm focal lengths are close enough together that I cannot tell them apart, looking at the subsequent photos. SO, I've been considering selling off one of these lenses and getting something a bit "further apart"- whether or not to keep the original 40mm & ditch the 50, or keep the 50 and sell the 40? etc etc, on & on and this internal debate will likely not be decided soon! So I'm constantly keeping my eye open for info another lenses (in Voigltander's line-up).They seem to create masses of a couple different focal lengths in several mounts. For example they have more than a couple 50s and a handful of 35s.... possibly a few 28mm lenses also! Some of these fall into their "Vintage Line" with single coatings and "character" built in! Others are multi-coated, modern lenses that get rave reviews and much love. Which indeed creates its whole own conundrum, no doubt worthy of a dedicated conversation elsewhere. Meanwhile, I've come across someone talking about the Voigltander 35mm f1.7 Ultron, which by & large is very well regarded. I'm not really a fan of wide angle lenses, per se, but (and here is today's question) as I have a 40mm lens,- and the f1.4 multi coated Nokton Classic is just superb if not a bit clunky on the ergonomics with its "focus tab"- wouldn't the 35 be just a wee bit wider? Or is that 5mmm difference in focal length significant enough that the 35 breaks over into the category of being a true "wide angle" lens? Attn: admins & moderators- wasn't certain where to put this post, it's more a lens question than a "rangefinder" question, yet the R3m is from the early 2000s... perhaps not super "classic" .... If there's another spot for this that's you deem more appropriate, please move this to there.
