When I first began to take flower close-ups with an SLR, I would get back slides with garden hoses, sprinklers etc. in BG. I got so upset with myself; how could I have missed that! Of course I was shooting at f/16 for front to back sharpness, and using the DOF check. Finally I learned that when focussing at f/2, The background was obliterated, while the view stopped down at f/16 becomes almost black beyond the subject. I always try to look outside the lens for distractions now, but it's easy to forget. But rangefinders have their drawbacks, as well: Lucien wrote: >Not so easy, because of the parallax with RF Another lesson was learned when I tried some landscapes with the M-3. The scene was a dirt road which receded through two trees which had bent over the road to form an arch. (OK, so it wasn't Half Dome It was still worth a frame or two.) I measured the foreground and background distance and set the focus on the DOF scale. Then I framed the trees so the arch would be just inside the frame. The slides, once again, were a disappointment. The tops of the trees where they crossed were cut off. The problem is that parallax correcting viewfinders don't correct parallax, they merely correct the framing for one focus distance! somewhere about a third of the way into the picture, on some weeds or something, the framing was perfect. The more distant background, in this case the more important part of the scene, was very misaligned with the actual exposure. One way to solve this would be to use a separate finder in the shoe set to infinity (or use an R!). Otherwise, to use an M with the built in finder where focus is close but BG alignment is critical, I figure you would have to 1)calculate the focus; 2) reset to infinity and frame; 3)lock down on a tripod; and 4)reset the focus distance. Whew! Anyone ever have/solve a similar situation? Nick Hunter
