I just picked up a used Nikkor 300/4 and I've been fiddling with it all afternoon. First the easy questions: Does anyone else think that the hood is too shallow? Does anyone use a different hood? Second, I'm not sure I like the slip-on leather lens cap. Does Nikon make an 82mm lens cap? How about 3rd party manufacturers? I don't want the $4.95 junk that falls off, I want something that will stay (like Nikon lens caps, for example). My final (and most important) question has to do with switching between AF and MF when using this lens on my F5. I notice that if I use the "A" and "M" switch on the focusing ring that I can manually focus the lens. However, I also noticed that the focusing pin which connects it to the body also turns while the lens is in MF mode. This means that if I want to manually focus the lens, I have to make sure that the body is also on "M." And if I want to AF, I have to switch the body to "C" or "S" as well as flipping the switch on the lens. This two step procedure going from AF to MF is really annoying. Is my lens broken, or is this normal behavior? Why did Nikon ever make it like this? Thanks in advance. Dan N.
