If you order from Hopf, may as well get the best he has, the borosilicate.
Yep, this was the one I was looking at. I'm going to measure up my screen tonight and send it on.

Since I haven't shot large format before, I'm wondering what the difference is between having more or less grid lines. Steve Hopf can do either 1 inch or half inch I think, but what do people tend to shoot with? The advantage I guess would be for things like horizons?
