24.1 x 36.0 mm as I measured it. Extra 0,5 mm will be useful - it is rather difficult to position the film precisely From the LS4000 pdf file: Scanning area (max.) 25.1 x 38mm (3,946 x 5,959 pixels) Effective area SA-21: 23.3 x 36.0mm (3,654 x 5,646) (size/pixels) MA-20(S): 25.1 x 36.8mm*

For sake of interest, Popular Photo rated their F3 test camera at 98.8% horizontally by 99.2% vertically. I guess that's about as close to 100% as one can expect. One thing that no one seems to take into consideration is the focal length of the lens used. Take some photos on the same roll of

Is it that big a difference? We're speaking of the light angle differences which can allow for an exposed area due to the gap between the internal frame mask within the camera and the film plane... so, that's based upon how far the guide tracks stand out from the frame surface. On the Nikon

All of the Nikon F series, the Canon F1, and the Topcon had 100% viewfinder coverage. One of the reason most SLR did not was because registration (viewfinder/film image coincidence) did not need to be as precise. Jim Sims Enoch's Vision, Inc. (Cary Enoch R...) wrote: At 23:40 02-06-01 -0700,

I just measured the FH-2 holder with a vernier calliper. Each frame opening is 23.5mm wide, 35.5mm long -- that means it's masking .25mm of each edge of the image. What size openings does the FH-3 holder have? 24.1 x 36.0 mm as I measured it. Extra 0,5 mm will be useful - it is rather

Greetings, Has anyone using the new Nikon LS4000 had experience removing a slide from the mount to get more of the image? Best way. Any problems with buckling or focus? Occasionally I crop too tight in the camera and my 1v allows no room for error with it's 100% viewfinder. I am speaking
