What UTTER Hogwash....
What UTTER Hogwash....
I have not tested it but I have been told by other 670 users that handholding lowers the image quality to the point that the image looks no better than a 35mm image.
Not you of course, but the advisor's you are listening to.
Think about it
1. a 670 frame is 4+ times greater than a 35mm frame. A 690 frame is 4.7 times greater than 35mm.
2. The Fuji is a leaf shutter, offering less shake potential than a focal plane or SLR shutter mechanism as are usually found in the majority of 35mm cameras.
3. EBC coated Fuji lenses are very likely sharper and higher quality image makers than the majority of 35mm lenses that exist today.
4. The bulk and weight of a Fuji GW allows the photographer to handhold steadier than a smaller, lighter 35mm camera when the shutter is pushed, given that the weight is not too great for a given photographer. In addition, the Fuji shutter is a sweet shutter to trip.
5. In my experience with a number of Fuji 645's to 690's, including the 65mm GSW lenses, I have never seen a situation where I would have opted for a 35mm for better image quality and focus characteristics.
6. Since film emulsions have developed parallel for 35mm and 120 roll film, there is no film advantage to 35mm over MF on any frame format.
7. Nothing about Fuji camera quality, or MF in general, supports any consideration of a 35mm frame matching the quality of a frame 2.75 (645) to 4.7 (690) times larger.
Now on the original posters question, since these are purely mechanical camera's with no stabilization features, I would (and do) hold to the reciprocal rule for hand holding. Perhaps 1/60th second on the 65mm GSW models and 1/125th on the 90/100mm lenses. 100 was the lens on the G690/GL690.
Furthermore, I do tend, at my age to use either a monopod, or a tripod. In fact, when I was younger, I was never too proud to use one of the best photographic tools ever invented... the tripod.
If your friends who shoot Fuji medium format cannot produce an image that blows 35mm out of the water, they need to look inward... not at the camera or lens.
