Hi. I’ve read thru some of the older posts but thought I’d renew the question a little. I’m looking for a good wide angle lens for my 5x7. Lightweight is important, an image circle needs to be good enough for small movements. 5x7 seems like a hard format for really wide stuff as most good wide angle lenses are designed for 4x5. I’ve tried an old 6in dagor but the image gets a bit fuzzy at the corners. Thanks for your thoughts, there is so much knowledge here!
