Beseler 45 V-XL vignetting; what's going on?

[Bob Salomon]

IC-racer: I can see why the may have designed that offset for that purpose (lens turret) but I don't have one of those. Even if I did the vignetting would still be there?

For those of you who have a 45V XL can you tell me what your part number is for the Lens Board Adapter? Mine is 10-49524. You can see where the number is listed below

Why don’t you just contact Beseler in PA and ask them?

Thanks. I did that on Friday. In the past they have taken a little while to get back with me. I came here because there are a lot of knowledgeable people. I've got some time today. I'm going to take it apart and put things back together. Maybe I will have an "Ahaa" moment. thanks again for your suggestions

Just get out the sabre saw and cut the throat out square. This allows you to mount a wide variety of lenses like the 240mm 5.6 Rodagon shown here that I use for 8X10. Note that I had to relieve the lens mount plate a bit for this large lens as well and trim the edges of the lens flange a bit. I doubt this mod would interfere with smooth operation of the Beseler turret if it were attached.
No lens that can go on the turret will cover 8X10. If cutting that notch out allowed light to shine through another lens while using the turret, just put a lens cap on it.

Thanks Neal

Just checked mine is also a 511 and has the obstruction. I have never noticed a problem, but none of the lenses I have used have reached the area. I just checked and the 210 companon might get close. I don't have it on a board. the 240 companon extends far enough to get past. My 10" eastman is the only lens that is big enough reach the obstruction. What lens are you using? If the lens can't reach it, it can't obscure. I second the try upper bellows adjustment before a saw.
