Hi, I'm using a Beaulieu 4008. When I do close up, using the wide angle, the focus looks the same wether it's on 3ft or on infinity. Is it normal?

Thanks

Yes -- Wide angles have lots of depth of field, and so do small formats.

I have a Schneider Kreuznach Ultra Wide Lens III with a Beaulieu 4008. Do I need to set the lens to macro? I've noticed when I do this everything is out of focus so I assume I don't use the macro setting and just leave the focal distance at infinity.

Hi, you need to use the macro setting on the 6-66 lens with the UWIII... Use the 6mm end of the lens, then obtain focus by moving the macro lever till all appears sharp in the viewfinder.

Thanks. You didn't mean the 66 end of the lens by any chance? I seem to have got the hang of it now alright but by using the focal length beyond the red macro line in combination with adjusting the macro slider.
