Hi all, First let me acknowledge that it's been substantially more than a couple of years since I was last on here. Work was busy, wife was ill, so photography - and APUG - took a back seat, and I let my subscription lapse. Anyway, things are looking good again, we're planning a trip to Italy in a couple of months, I've dusted off the LF gear, and I'm back on APUG. I'm delighted to see it is still in business. And now to the question that has brought me back. I have a Nikon Nikkor-M 300mm 1:9 lens mounted in what seems to be the appropriate Copal shutter. My Horseman 45FA doesn't have enough extension by itself for this lens but I use it with a special lensboard with a built-in extension. I've noticed that the focus is a little soft. No matter how hard I try with a loupe to get the image as sharp as possible, the results are not as sharp as they are with any other lens I have. At first I assumed that the focal length meant that it was more sensitive to vibration and I was getting tiny amounts of camera shake. But over time I have realised that it must be the lens itself. It's not terribly bad, but I'd be better off getting a similar effective focal length with a sharper lens and a 6x8cm back. Which is not what I want. Everything seems to be assembled nice and tightly. Is this softness likely to be a characteristic of the lens? If so does anyone have a suggested alternative? If there is something wrong, is there any way of finding out what it is? I do not have access to any special equipment. Grateful for any suggestions.
