I thought it would be fun to hear what other's opinion might be here. There is just so much out there by way of choices, and reviews, its hard to fathom. So here: I currently have adapters for Minolta MC/MD, M42, and Nikon F. As you can see in my signature I use a Vivitar 19 f3.5 on the MC, a Nikon 50 f2 on the F, and a Super-Takumar 50 f1.4 or Agfa 130 f4 on the M42. What is your opinion on another lens to add to this collection? I would like to stick with just that, no additional criteria, but I understand that might be difficult. You can check out my Flickr page to see what I usually shoot. I tend to like wide, and contrasty. I would love to have long for birds and wildlife, but just don't have the funds for long native glass and legacy becomes harder and harder to focus at longer focal lengths. Thanks!
