I want a 0.95 Voigtlander to create thin DOF and a lot of background separation. I can't afford both the 25 and the 42. I have the following lenses: 28/2, 30/2.8, 40/1.8, 50/1.7 and regardless of which Voigtlander I buy, I'm already budgeting to get the 20/1.7, 45/1.8, and cheap Fujian 25/1.4 this year (the 75 is further in the future). http://howmuchblur.com/#compare-2x-...m-f1.8-and-2x-135mm-f3.2-on-a-3m-wide-subject The 42 is the one to get for background blur and will even beat the 75. But considering the 28/2 is by far my most used lens because I'm often inside with lower light, a 25/0.95 would get a lot more use than a 42/0.95. And plus since the backgrounds will be closer indoors, the differences won't be as pronounced between the 25 and 42. But the 42 is the BEST lens for most background separation and if I'm going to spend money why not buy the best!? Ugh! Maybe someone can help me with the low-light math. Although the FL is longer, since it's nearly two stops faster, it seems to me that the 42/0.95 will, in low-light, be BETTER than the following lenses: 14/2.5, 17/1.8, 20/1.7, 25/1.4, 25/1.8. Am I right here? I don't think many people have these Voigtlander lenses but to me they seem really nice!
