Pros: Build quality, a real pleasure to use.
Cons: Max. magnification 1:2

This macro lens is small and compact and a pleasure to use with its smooth focusing and all-metal lens barrel construction. It focuses down to 24 cm and provides 0.5 magnification on a film camera. It must be used with an extension tube to get to life size (1:1) magnification. It is very easy to fine tune focus. The lens can also be used as a normal lens, but focusing is a bit more difficult on faraway objects than on a standard 50mm lens, which has a one or one and a half stop advantage over the macro.

Optically and mechanically I can't find any flaws at all. This lens is SHARP:

For macro photography I do prefer a longer focal length, though, at least 100mm which allows for more distance to the subject.

Max. aperture: 2.8
Min. aperture: 22
No. of aperture blades: 6
Closest focusing distance: 24 cm
Max. magnification: 0.5
Filter size: 49mm
Weight: 220g

Pros: small, sharp
Cons: only 1:2

the only lens I regret selling. It only goes to 1:2 and I wanted 1:1 but simply its small and sharp and I look back at the images I took with it, and they have a nice look (if the person who bought sees this, I want it back! .

Pros: Construction, sharp images
Cons: not 1:1

Bought it new over 25 years ago and never regretted the purchase. Use it exclusively for macro work. Extremely sharp. Great construction and a joy to focus. Some times would have liked a 100mm macro but the majority of the time, this lens did it all for me. Some of my best shots were taken with this lens. Highly recommended.

Pros: One of the sharpest Pentax primes, color, contrast
Cons: none

A superb prime, scintillating colors and contrast. And it's one of the sharpest lenses I've used.

I've owned the FA version of this also, and it's essentially the same lens - in fact, this one may be sharper.

It has the perfect throw - I can manually focus this as easily as any Tak, and can even nail moving objects with ease.

It's realtively light, so it's absolutely perfect for casual macro and close-focus - no handshake like you get with 90mm+ macros.

Highly recommended.

Pros: Optical and mechanical qualities, both macro & standard abilities, look when mounted on K100D
Cons: no

I found this lens on Ebay after missing a M50/f4 macro. It was more expensive but I never regretted to buy it..
The lens is very well built (metal) and seems made to be used for a lifetime.
Quality of pictures in standard use is close to other pentax A or M 50, and macro use is a pleasure (smooth and fine focus ring), with a nice bokeh.

Ideal for insects, flowers etc..as well for lanscape or children pictures..

I think it could be very hard to find an other lens doing this job for this price.
