Hi, I'm using a Hasselblad 500C/M with the standard 80mm T* lens. I'm shooting black+white, mostly landscapes and objects. I love this camera. I'd like to get a wide-angle lens and was wondering if anyone can offer me some comments regarding the type of lens and model? I think a 30mm lens would be too wide, the images perhaps too distorted for my purposes. I've looked on KEH to see what's available used and I see there are also 40mm and 50mm lens, however they range widely in price according to condition. Is anyone familiar with these focal length lens and can make some recommendations? Thanks!
