(sorry for spawning a number of threads. I'm kind of guilty that as of this post, three of the top four threads were started by me...)
I just bought a Nikkor SW 75mm f4.5. I'm sure this will work fine on my Shen Hao, but i'd like to try using it on the Master Technika as well. Nikon brochures list the FFD of the lens at 81.3mm. I pulled the front standard onto the focusing rail enough so that the the entire length of the bottom of the standard was on rail, but the rear was flush with the rear of the rail. If I mounted it any further back, the standard was a little wobbly. Then I retracted the focusing rail to the rear position. I don't have any super accurate measurement devices, but with a film holder loaded and dark slide out, and a ruler stuck through the opening of the front standard, resting against the back of the film holder, the depth seems to be in the vicinity of 85mm. enough to know that a recessed lens board will be required.
The trick now is to determine how recessed. Looking on eBay, I see Copal 0, Technika type (generic) lens board with 11, 15,17, 19, and 21mm recessed mounts. I'm going to try to get a better measurements, but it seem likely with the bed at the standard 90 degree position, even the smallest 11mm, will give me sufficient depth. The problem is I expect that the bed will be in the shot, and I know that if I drop the bed and tilt the front standard, that moves the lens board further from the film plane.
I haven't measured with the bed dropped to either position yet, but I wanted to ask a simple question--anyone who has done this, can I get the bed out of the frame with a little rise, or do I really need to drop the bed? The manual seems to imply that in landscape, a 72mm lens is ok without dropping the bed, but real world confirmation would be nice. It also says that rotated to portrait, I'd need to drop the bed to its lowest position.
Second, more generally, if anyone has shot a 75mm on a MT, what is your setup? Mine isn't a 2000 or 3000, so I can't really focus on the inner rail (I don't know when that was introduced but it sounds like a neat feature.)
