Close focusing
I want to do some table-top close-up work with my 10x8 and am considering ways of increasing the magnification. Has anyone used supplementary magnifying lens, and if so with what result?

Yep, I did that the other day on the 13x18. Stacked up three close up lens - 1x; 2x; & 4x. Was close. Snap was a masterpiece. Nearly. Well, it would have been if it had worked.

More conservative, I tend to use one at a time.
But diopters are fine, and if you make your own (ripped out of old lenses) they can also be fun(ky).

I've used a 10+ dioptre 77mm close-up lens on my 300mm f5.6 Fujinon-W and the image on 8x10 is surprisingly usable. Why?
Corner image definition is "off" but I never put my main subject there anyway. The lens is stopped way down, f90 sometimes, so aperture dependent aberrations are dramatically reduced. The camera remains short so a lot of bend, sag, and wobble is avoided. Doing close-ups with a wooden field camera and maximum bellows extension (four feet) is a shaky exercise. And my arms are too short for me to see the ground glass and and adjust the lens aperture at the same time! Downsides include lighting problems with a 100mm working distance. Everything tends to be dominated by the shadow of the camera itself. Plus the near to far perspective of subject elements tends to be a bit brutal. Close-up table-top photography can degenerate into an exercise involving extreme camera movements and long exposures. It is good to have a high frustration threshold.

I've used a Nikon 5T closeup diopter on a 150mm symmar-S to get closer using 6x7 on a camera with limited bellows. There were no effects in the shots to make you think there'd been any degredation in quality (can't comment on field curvature etc as I was shooting real 3D things no flat objects).
I'd use one (if you can get hold of one!) without hesitation. I've used the same filter on a nikon 100mm (35mm) and Mamiya 150mm (645) and got very sharp results. |

Have you considered 'top hat' extension lens panels? I don't know if these will get you close enough for what you're after.

Robert White only does the 0 & 1 size, so you would need to go to Badger or Mid-West. I have my 210 mounted on a No1 Top Hat and having assembled the thing, its fine. However, getting the thing assembled was a right royal PIA I might go back and have another go at mine and try something like clear nail varnish on the threads - as a non-permanent Loctite. Martin |
