Just getting into close-up and macro photography here, And I'm getting tired already of trying to peer thru the normal viewfinder of my F4 at the wee flowers and insects. I see in Moose Peterson's Nikon System Handbook, that there are three possible solutions to this problem which would allow me to look down into the camera from above. These are the DW-20 waist level finder, which has the flip open hood like my old YaschicaMat, (Is this one also good for "normal" photography?) the DW-21 high magnification finder which has a large range diopter adjustment, and the DR-3 right angle finder. (Which is probably a LOT less expensive than either finder!) I would like to hear from folks who have used any, or all of these as to their pros, cons and/or preferences. I know the finders reverse the image, but if memory serves, the angle finder maintains it correctly. Also, can the DR-3 be fitted to the eyepiece on the standard DP-20 finder? This has a somewhat larger thread mount than the older non-HP cameras. Many thanks. Bill Wilson
