Ok...I'm officially an idiot. Appears after a closer look and thinking about it... The focus ring was loose. Thats all!:rolleyes: Thanks anyway everyone.
The small brass looking ring that I use to adjust the beam: should it have a lens inside? otherwise what am I adjusting? There is nothing here but a ring.on my 501B
I found the same thing happened to me. I pulled mine out to use today and all it does is produce a rectangle image that I cannot change. Is there another small lens that is supposed to fit inside the center adjustable ring (that I somehow lost?) If so how/where do I find a replacement? :cryyy:
