Something I've been noticing as I foray into adapted lenses: Wide angle stuff seems to be more rare and quite expensive, at least based on my non-scientific hunting on eBay. Lot of nice options in the 25-50mm range. For example I have a Pentax 25mm 1.4 TV lens c-mount and a Super Takumar 50mm 1.4 that both cost less than $100. Compare that to the native options in that area (Panasonic-Leica 25mm, Olympus 45mm for example) and there are good deals to be had. Going much wider than that prices climb higher. It seems like anything 20mm or less that is adaptable for M 4/3 sells for a minimum of $200 and usually much higher. Once you hit the $300 range you can get a M 4/3 lens like the 14mm kit lens or the Samyang Fisheye. Adapted lenses don't have the same price advantage. Also supply is more limited: in a line of lenses like Super Takumar you might see one 18mm or 20mm wide angle listed versus dozens of 28, 35, 50 and 55s. (Nevermind the tele lenses... 135mm lenses go for peanuts. Like 10 bucks) Crop factor plays a part, of course. To get wide angle on the M 4/3 you need to go really wide. I have a couple of NIB c-mount 12.5mm en route to play with that I got dirt cheap but don't expect I will get full coverage. Thoughts and suggestions welcome.
