Hi Apologies for asking such a daft question, but I have just bought my first Macro lense. It's the Nikon Nikor Micro 60mm AF lense. My camera is a non-fancy 35mm F65 Nikon SLR. I am trying to understand why the lense only functions when stopped down to f32? If I set the lens to any other f stop I get 'fEE' blinking in the LCD and viewfinder which apparenty means (according to http://photo.net/bboard/q-and-a-fetch-msg?msg_id=00GJzs&tag=) that 'CPU Nikor lense is not set to it's minimum aperature'. Remedy - set to minimum aperature. And sure enough, it works when I do that. But what I don't understand, is why are the other f stops there to choose from if I cannot use them? Also, the camera itself reports different f values depending on the light etc. I'm sorry for being such a dumbo, but I've never had such a fancy lense before. My other two lenses do not have ring stops on them - I set the f stop via the camera body. My former Olympus OM-10 did not have automatic features. What's confusing me, I guess, is that there's two f stop values. One on the barrel, and one on the camera? Can anyone explain, or give me some URLS to a Macro HOW TO? Thanks a lot - great site. Ted (PS I have read the manual, but it does not explain fully - only IRO of mounting the lense on certain bodies may not be possible while it's locked).
