I just got back some disasterous slides taken with my new M6HM. Most of the photographs were fine, but at several points on the roll of film I wasted a few frames to check the sharpness of my lenses, specifically my 75/1.4. These were just some shots taken from my balconey, at 1.4. The resulting photos were terrible, way out of focus. In one image, what should have been in focus was a transmission tower, perhaps a mile away. Instead, some nearby tree branches were in focus. This happened repeatedly over about 6 consecutive images. I tried comparing focus with my old M6 (whose focus I trust), by measuring off 8 feet from a mark on a wall, and mounting each of the two cameras on a tripod. I focused as carefully as I could with one camera, and then without changing the focus, removed the lens, and replaced the camera on the tripod with the other one. I then remounted the lens. Surprisingly (actually, I would hope not!), the focus for all of the lenses that I tried were bang on with both cameras. There didn't appear to be any variance visible in the viewfinders at all. So I am pretty sure that if there is any focus error in my new camera, it will be very slight. Now, one slide shows something that may explain it. Parts of the foreground and background appear in focus, while the middle ground is completey fuzzy. I assume this can only be caused by the film not being held flat (I will scan the slide, though I'm not sure if web page viewing will show up the problem). I'm not sure if this is good news. Has anyone else had this kind of problem? I find that I don't trust the camera now. How can I know if the film is being transported correctly or not? I ran off another test roll (shooting a variety of subjects with various lenses, all wide open), and hopefully will develop it some time today. Dan C.
