pentax 100 mm macro wr

Is there more than one model of this lens? There is great price disparity among distributors.

There are a few Pentax 100 Macros but only one is WR. Also look at f because that varies across models with f4 being the default on older models and 2.8 on the DFAs. This is the WR model.

Which is more expensive than the equivalent non-WR DFA model.

There are a couple versions, but only one is in production now. Some stores might have the older one in stock, but.. its been a while.
The DFA 100mm macro WR. WR, 1:1 macro, has QS, has metal barrel, no aperture ring, no focus limiter
DFA 100mm macro. This is the older version, looks a little different, slightly bigger. Not WR, has focus clamp.
F 100m macro, FA 100mm macro. Older still. Same optical construction as the newer ones, but might have older lens coatings. Not WR. Might have focus clamp and focus limiter.
All of these lenses are optically great and will give you true 1:1 macro magnification. Some even older 100mm macro lenses only give you 1:2.
