I made the mistake of purchasing a reasonably priced, 90mm Super Angulon XL lens. I thought, geepers, all that image circle. And as I mentioned, the price was reasonable.
But, what a HUGE lens. Oh my gosh, it has a 95mm filter thread! I've standardized on 77mm filters. Maybe I can use rear filtration? Or use gels on the front?
Moreover, this lens was too big to use with my camera's compendium lens shade. So, it drove me to completely reconfigure my Arca 4x5. I've been using one with a Metric 6x9 front standard, and a Metric rear format frame mounted on an old-style Type A (axial tilt) function carrier. So, I swapped out the 6x9 front standard for the Type A old-style, axial tilt front standard which accepts the old-style compendium lens hoods. These hoods are absolutely the best I've seen and will work well the 90mm SA XL. (But of course, this doesn't solve the 95mm front filter thread problem.)
What REALLY bored me with this lens, I removed the rear element and found out that, at some point, it may have been dropped. OH NO, THE REAR THREADS HAVE BEEN SCUFFED! I missed this in my initial examination, and it was too late to return the lens. Fortunately, the rear element has a peculiar design where the rear threads don't actually abut the glass. So, I don't think that this will affect image quality. But, IT SURE AFFECTS MY ABILITY TO RESELL THE LENS!
You know, greed isn't necessarily just financial; it can also extend to image circles. I got "greedy" with this lens, and look where it landed me.
Well at least, I really like my reconfigured 4x5. So, some good has come from this purchase.
