I couldn't find anything on this using the search. We have about 15-20 26 degree barrels that act like zooms. Basically, with the barrel all the way in, they have a sharp edge with the correct beam spread. Start running the barrel out and it slowly starts zooming in with a slight fuzz to it. All the way out produces a soft focus w/ a 19 degree beam spread.
They are the Rev-J barrels. I pulled them apart and the dot is facing the right direction and the lens is in the correct spot. Bench focus is not the issue because swapping barrels with one that behaves properly only moves the issue to a new location. Our only solution has been to drop diffusion into it to achieve the desired softness.
Anyone ever hear of or have this problem before? I can't think of anything else at this point other than several defective lenses.
