SO I have been tossing around the idea of a wide angle lens for my 4x5. I thought I had settled on a 125 but now I see a 90mm angulon for the right price, but I am having trouble finding info on it. Specifically Image circle. I did read that the QC on angulons was iffy in the beginning. If I do get an angulon what should I do to see if it is a dog or not? I do not have the ability to get a sheet of film developed right away. Will the effects of a dog angulon be visible on the GG?
