I should mention ahead of time that I barely have a clue what I am doing but I am trying to get the equipment sorted out before I get into relearning fully how to use it (last time in a dark room was high school). The biggest question is a lens compatibility issue. With the S.K. Componon 50mm F4 that I got with the enlarger I could get a 35mm image in focus if I cranked the focus until the bellows was positively mashed flat into itself. I got a good deal on a like new Nikkor N 50mm 2.8 and really liked the extra stop for focusing brightness. Unfortunately now the bellows would have to be mashed more than flat to get the image in focus. I read about this in another thread with actually the exact same situation and after verifying he wasn't operating it wrong, the advice was to get the Beseler 8022 5/8" recessed lens board and that would allow the extra room for focusing (hopefully this huge lens fits in the recess). Unfortunately the original poster never mentioned after whether the advice worked or not and that particular lens board only seems to be available new at the moment and for a ridiculous price so I just wanted to confirm that getting that was the right action to fix the issue. (might have just found one cheap but don't know yet) Seems odd that they would design the thing so that the lens for the most common film size used with it barely works right, I feel like I am missing something. Second question that relates to that, my 23c is the regular height, but I got the XL booster bracket along with it for when I might make larger prints later. Would I still use the 50mm lens to do 35mm prints of the smaller size or does that extra height change what lens I would want? Also what effect will that added height have on my current focusing problem? It seems like enlargers work like parfocal camera zoom lenses where you set the focus and then can zoom in and out without changing the focus. I figure I might eventually just put the XL bracket in and leave it there, if nothing else the extra distance would reduce the light and give me more working time when making prints right? I have more questions but that's a big enough mess to start.
