Greetings, all---
Today, I enabled myself with the Pentax smc FA 100mm 2.8 macro lens.
Funny thing is, it happened kind of by accident... I thought I was
purchasing the DFA 100mm 2.8 macro (the non-WR version), but it turns
out I overlooked the missing "D" when I placed my order. Whoops. [
... ]
What I wonder is this: what am I missing out on because of my
shopping cart mix-up? (Besides the price difference...) I'm not sure
I understand the difference between the DFA & FA designations... Are
there other features of either lens that I should consider before I
declare this one a keeper?
I think the DFA version is supposed to be "optimised for digital"
(whatever that means - slight modifications of the coating, perhaps),
but without changes to the basic optical formula, as far as I
understand. It does not have the focus limiter fix of the FA.
Typing way too fast, again. I meant to say limiter *switch*...

It is much smaller and lighter, which I suppose may be convenient. On
the other hand, the FA probably feels a lot more like a "real lens",
and you can drop it on the pavement from a fair height without
breaking anything, or at least that's true for the similar F-version,
which I have (yes, I've tried...)
