Hello all, I have recently been using a Mamiya RZ67 Professional with both a 90mm and 180mm lens and WLF. I bought it from eBay and I do not know the model of the ground glass it has a split screen dot in the middle with a second ring that does not act like the typical microprism. I would guess it is a Type C, but I could be mistaken. Now, I’m a child of the digital age and I am having a very difficult time achieving critical focus with this comparatively ancient camera. I know that there are issues with the focus/recompose method, but if I want my subject off-center, I must strain my eyes to imagine what the image would look like without the matte finish of the ground glass. Not a perfect solution. I bought a plastic 8x loupe, to help, but it really doesn’t fix my off center issue. I am beginning to think that the loupe is too strong and something in the 4-6x would be a better improvement. A loupe in the 4-6x range would allow me to see more of the image together. Even so, what is the best way to achieve focus on an off-center subject? If I lock the camera dead centered so that the focal point is on the subject, focus with the split screen, then recompose by rotating the ballhead on its fixed axis, would that be an accurate way of focusing? Though now that I say that, I would need to make sure that the ballhead base is also level to prevent any kind of tilt in the composition. I believe that the focus/recompose issue arises when the subject is focused on, then the camera is moved up or down, on an axis that is not fixed, such as hand holding. Most of my images are taken at night and I really enjoy still lifes, skylines, abandoned buildings, unusual cars, and the like. I would be more interested in using my 5DIII for people or anything that won’t put up with my slow fine-tuning. Obviously I could center the subject and just crop the final frame to get the image that I want, but then I would lose precious negative size. I’m wondering if I should just ignore the split screen and use a loupe to I’m a firm believer in tripod shooting and am not afraid to take the time to make a technically good photograph. I hope that the finished image is also aesthetically good, but sometimes I shoot a real dud despite accurate focus. Any advice would be greatly appreciated!
