Why not DFA 100 2.8 WR? Its built quality is superb. For macro, 100mm is more convenient IMHO. You will need that extra distance in case you want to use extension tube or close up filter for bigger magnification.

You can read about the lens at Pentax Forum lens review.

It's a matter of choice for the focal length, be it 35mm, 50mm, 90mm, 100mm, 125mm, 180mm etc.:)

All macro lenses can be described with 1 word - sharp.

Bigger question is what you want to use it for - bugs? product? food? portraits?

for bugs, 50mm is too short. Unless you know how to approach very gently, your subjects will fly away :) a 100mm is more practical.

for the rest, do you need a macro lens? Do you need 1:1?

Macro lenses have a long focus throw. that slows down AF.

At maximum magnification, 1:1 mag, the working distance is short, just a couple of inches away. All macro lenses produce sharp images within that acceptable range according to the set apertures.

More of a handy lens cos of the shorter focal length, easier to handheld than those heavier macro lenses.

Sharper wide open than even the DFA100. ;)

Just check for fogging on the rear elements if you are buying pre-owned.

I had the DFA 50mm f/2.8 Macro and I would say it is good and sharp lens. Definitely like the Quick Shift feature. I use this focal length a lot for product shots. Macro isn't just about shooting bugs and there is definitely a place for the 50mm macro. Most modern macro lenses will go to 1:1 magnification, so choose your lens based on the angle of view and working distance to the subject.

I owned this lens before, and it's really sharp as SBC had indicated, and really good for flowers.

Snaps of it, very little processing from Picasa which wasn't really good but was what I know back then...









Having said that, I decided to only have 1 macro, and shrunk my collection of macros to just 1 - 100mm WR. Like what Denis said, decide on the angle of view and object distance, get the lens, and keep shooting with it.
