Macro LBA Dilemma - FA100 f/2.8 or DFA100 f/2.8?

I've been bitten by the macro bug and need some "What would you do?" opinions.... please

I've read the reviews and numerous macro threads and I think that I understand the physical differences between the two. I don't consider the weight difference to be a big issue... or is it?

My main question is this...

" If you were in the market for a macro lens and faced with the choice of the DFA 100 at the rebated retail or a used FA 100 priced at $260, which would you choose and why?"

Thanks in advance for your input!

Bud

Hi Bud,
I have only just got the DFA and despite limited use I am very impressed with the results.
I know nothing about the FA series.
Cheers

Problem solved....

.... I go the site to make the purchase and da**it, if some lucky, less indecisive soul hasn't already snatched it up!! (If it was a forum member, I'm expecting to see some spectacular shots.... soon!)

That'll teach me!!!

Soooo.... who has an FA 100 they want part with?

This LBA is a wicked, wicked thing.....

Go for the FA without a doubt!

In my opinion there are too many aberration problems with the DA 100. Some of them, like the CA is correctable. The PF in the lens can be corrected with at least one software program but not through CS2 or any other software program I am aware of.

There are others on this forum which can vouch for this problem better than I can.

I need an FA as well as it's undoubtedly better...check out my WTB thread

The focus limiter is what I'm going for.

There is one on ebay now, and as I feared, it is out of my league right now.

Optically I doubt that one can establish any difference.

Mechanically the FA is better, no question, but it is very heavy.
The DFA to the contrary is the lightest and smallest macro available, by far.

The FA has the limiter which might be useful when you shoot other things than macro as well. But its missing is not really a problem with the fast AF of the K10.

The DFA has Quickshift, which I find very useful for macro. A much underrated feature.

I bought the DFA.

DFA is certainly light and compact. I heard the optical design of DFA version is different from Fa version. EarlierI had my DFA 100 macro hitting off the stairs in a mountain hiking trip - the lens survived the banging.

p.s. I do see Fa images are way sharper than my DFA 100 macro images though ...

The optical formula is basically the same. Same number of elements, only slight, perhaps cosmetical differences. The aperture has been moved further back though.

Huh? How did you test this? "way sharper"?
From my tests (tripod, focus array ...) I can say that the resolution of the DFA is probably limited by the sensor.

Geee the D-FA is anything but not sharp. See what I mean?

Not cropped.

I had a long winded reply that very non-concisely hit these points and some personal opinion. For macro that Quickshift feature is great, why didn't they have that feature right from the start? Unless you have an SLR that you want to do macro with too, I'd start with the DFA first.
