Originally posted by Rondec I don't know. Olympus has a 17mm f1.8 and a 12mm f2. Voigtlander makes 17, 25, and 42mm lenses that are f0.95. Anyway, if you look at the DA limiteds, the very fastest one is the DA 70 which is just f2.4. The FA limiteds (I own 2) are very nice, but not exactly a whole lot cheaper than the Voigtlanders.
Voigtlander 17mm f/0.95: $1250 , has no AF, is a bit slower and a bit longer than the 31mm F/1.8, and is $300 more expensive.
Voigtlander 25mm f/0.95: $1200, has no AF, is the same speed and a bit longer than the 43mm f/1.9, and is $600 more expensive
Voigtlander 25mm f/0.95: $1200, has no AF, is quite a bit slower and the same length as the 50mm f/1.4, and is $800 more expensive
Voigtlander 42mm f/0.95: not introduced yet, will probably be $300-700 more than the 77mm
If you compare the FA's to the Voigtlanders I suspect you'll have to spend $1500 more (hey, that difference will buy you a full-frame camera!) and have far worse resolution to boot.
What's the AF price advantage in the market... $200? $400? per lens...?
