Will a six inch Artar APO F9 cover 4X5?
Will a six inch Artar APO F9 cover 4X5?
Goerz says no -- see http://www.cameraeccentric.com/html/info/goerz_3.html -- but I'm sure that users will pop up to say yes.
Thanks Dan. I'm looking at a real nice one on ebay. The guy is saying the lens covers 5X7!Originally Posted by Dan Fromm
Dialytes like the Artar have fairly narrow coverage, around 46 degrees for many, so it's highly unlikely a 6 inch will cover 5x7, if it covers 4x5 it will be pretty tight. It might fully illuminate but does it put usable image in the corners or mush?
Yeah, I thought it sounded a bit over optimistic. I going to pass on it.
I think you need an 8 inch dialyte to be on the safe side, good luck with the hunt.
Lenses cover more as we focus closer to the subject: the film moves further behind the lens and the circle of coverage gets large. By the time we reach 1:1 magnification, the image circle doubles in diameter, compared to its circle at infinity.
I think we can assume the OP was asking if it covered at infinity.
