Whoops, yes - #01F, not 10F! My 90mm/2.5 is coded 52BB and has the 55mm
filter ring. Snagged it with the extension tube, caps and hood for US$100 -
almost unmarked :)
Haven't used it with the tube or the 2X yet - first attempt at macro I
messed up depth of field. Nice portrait lens but! The early version has a
49mm filter ring. There is a later version - 90/2.8 which goes to 1:1
without the extension tube but I believe it isn't as sharp. That version
also comes in AF versions.
The 18F is 44mm long! - with an internal diameter of 39mm although with a
couple of masking projections. Big enough to put a tripod mount on it -
same one that fits the 300/5.6 and some long zooms.
