Henchman Posted March 13, 2021 Share Posted March 13, 2021 So as I'm getting ready to start shooting my micro budget feature, I decided to do a final test between those 3 scopes and a Voigtlander 40mm F2 as taking lens, wide open at F2. Well, I was surprised. I used the cover of a book at 40 feet. The scope I expected to perform the worst, in fact was the sharpest of all three. I could read the title from 40 feet away. Here are the picture. Emanuel and Juank 2 Quote Link to comment Share on other sites More sharing options...
au8ust Posted March 14, 2021 Share Posted March 14, 2021 The Isco Ultra Star should be a lot sharper. Maybe you got a bad copy that needed to be tuned up? Emanuel 1 Quote Link to comment Share on other sites More sharing options...

Henchman Posted March 27, 2021 Author Share Posted March 27, 2021 Spent time aligning the Isco. It's definitely sharper. Not as sharp as the B&h single focus though. Only downside with the B&h is i have to use a 50mm or more lens. The other 2 I can use my 40mm voigtlander. And the Isco can go to 35mm with the native 7artisans 35. But the artisan isn't terribly sharp itself. So I'm looking fur a 35mm mft pancake lense f2 or less With my.0.8x VD that gives me the equivalant of a 28mm Quote Link to comment Share on other sites More sharing options...
