I have had a super angulon 90 f 8 for many years that i have used rarely because i am not attracted to the moderate wide angle look that has in my 4 x 5 . Now i have a 5 x 7 and i have been told that the above lens covers this format...... True? I am not lazy, i am waiting for a lensboard, so that i will be able to check myself. I am posting this to alleviate the suspense.....
