FujiGSW690II & FujiGW690II Focus problems

Re: FujiGSW690II & FujiGW690II Focus problems.

I seem to be also having problems with the hyperfocal focusing. I took some pics of a historical building in Bonn with the camera set up on a tripod and took a series of fotos at f:11,16,22,32. all were not in focus.I was around 300m from the building on a grass field. On looking at the slides somewhere on the grass there seems to be an area where the sharpness is there, but the building is unsharp. All were taken with infinity set to the markings on the lens for the f.stop.

Any ideas?

I have a GW690 II and a GSW690 III. It's been my experience that the depth-of-field markings on these cameras are somewhat optimistic if you are interested in sharpness. For hyperfocal focusing, I set the infinity mark on a stop which is 2 stops wider than the markings suggest. If my aperture is f/16, I must set the infinity mark on f/8 to ensure that objects at infinity are satisfactorily in focus.

I have a GW690II and have also found you can't trust the DOF markings on the barrel. My lens, however performs well if I close it down 1 stop less than rated (f8 instead of F11, etc).In fact, it's good to do this with DOF scales on all lenses, they're all optimistic. Fuji is notorious for many variations in lens manufacture (in performance, not lens quality) so each lens is sort of a "custom lens". You have to determine the best performance of your own lens.

Good Luck

I compared the DOF markings on my GSW690 with those from textbook

DOF calculations (in this case from formulas in a View Camera

magazine article) and found that except at f/32 they were almost

exactly the "recommended" MF values (I believe it was a .0025mm

circle of confusion, but the program is on my computer at home).

Personally I find this circle of confusion marginal for 11x14 and too

large for anything larger, but that is not a Fuji problem -- my

Rolleiflexes suffer the same "problem." If in a hurry I stop

down an additional stop, otherwise I use a chart calculated for

a smaller circle of confusion.
