Why all the different body caps?
Just curious as to why nikon produce so many different body caps? My lens scope converter came with the BF-1, D2X with the BF-1A and my TC-20E II with the BF-3. The BF-3 is the only one that fits all 3 of those (and also nikon extension tubes) - so why not just manufacture the BF-3 from now on? - seems like it fits everything. It can be a bit anoying when swapping in the field.

The BF-3 differs from the other two in that it emulates and AF-S lens, in mount. The TC-20E II is designed to work with AF-S lenses only, which have a notch that clears the extra little tab on these converters. Non-AF-S lenses don't, so they won't fit, and so neither will the 1 or the 1A without some filing.
I have one BF-1 and a few BF-1As. The BF-1 came with my recently acquired F3/T and I tried to put it on my D2x the other day, without thinking. It was then that I noticed that the BF-1 would not fit any of my AF bodies, whereas the 1A fits both AF and MF. I'm guessing that the difference has something to do with clearance for the AF contacts.

I removed the tab on my TC-20E II so it isn't that. Closer inspection shows that the BF-3 is effectively deeper - see picture below showing BF-1 (left) and BF-3 (right). The BF-3 bulges at the front to accomodate the protruding front element of the TC-??E type converters. I'll know to ask for BF-3 caps from now when buying replacements/spares so that they fit everything (hopefully!).
Nice website by the way DrH. I'm a Dr.H. too - well, I'm just doing my corrections so i'm semi Dr.H. Graduation in June - woohoo
