Focusing a Noblex 150UX
« on: June 15, 2019, 03:28:32 pm »

I need some help understanding the 3 focusing zones on a Noblex 150UX.

What actual distances do the 3 focusing zones (N, M, infinity) represent?

On infinity is the lens actually focused at infinity?

Can I focus in-between these fixed zones?

I make 8ft wide prints and have mostly been shooting at f8 1/2 and infinity but sometimes the lower 1/5th of the foreground is a little too blurry and I was thinking of focus stacking.

I'd like to limit stacking to 2-3 images (to save on drum scanning costs and limit changing rolls) - at my print size can I get away with with shooting 3 images at f8 in each zone?

I have a Fotoman rangefinder but never know exactly where to set the corresponding focus on the camera for maximum image quality. I almost always want the distant background in focus but often have a foreground element at 5-7 meters that also needs be tack sharp.

I think if you shoot at infinity and F16 everything will be in Focus.

Won't diffraction become an issue at those sizes?

I had a 135 U but I can't remember the settings ...
But on film medium format f16 was always perfect.
