Unlike some other sites, we here at Iftimestoodstill Productions don’t do our testing using hand lotion… (snicker)
Only the finest compressed air will do.
Incidentally, I recently installed a new focusing screen in one of the new finds, and was busily running around photographing bottles. And other things.
If you’re in the market, you really should give Rick Oleson a look. Although not as perfectly crisp as the Maxwell Brightscreens, they are a quarter of the price, and function as an excellent replacement to any original equipment. I have ordered two screens from Rick, and have been completely thrilled with the result and support.
