I could not find a Pentax FA 200 macro, which may be one of the best macros ever made. In need of a longer focal length to compliment my other three macros I purchased this lens, 180 EX DG IF APO, with some trepidation.
The lens is quite capable of excellent imaging. It is quite sharp wide open and peaks at f/11. I find that sharpness still holds together even with refraction at even the smallest apatures. Color rendition is outstanding. Some macro images can be seen at pbase.com/scgushue if you wish to judge for yourself.
The lens is big and some might say heavy. That said it delivers big on imaging. The finsih is nice, contrast is outstanding, flaring is fairly well controlled too.
My only problem with the lens is occasionally the manual focus rotation seems to lock up (as though you are grinding sand in the focus ring) so I have to point the camera towards the sky to get it to focus smoothly. A minor problem that only occasionally manifests itself.

I have had this lens about a year now and use it primarily for wild flower macros. I have backpacked it with a Canon 350 in to remote locations.Even though it is a large lens it's capabilities make it well worth the effort.

This lens is incredibly sharp over a fairly wide range and I am very pleased with the results from F/8 to F/13. The background is buttery smooth and has nice colors and contrast. I can easily push the limits of the Canon 350 sensor.

The auto focus is slow but very accurate. I have shot butterflies in flight but the autofocus was working pretty hard to try to keep up with the moving target. Using the correct distance range helps speed up the autofucus hunt. Most of the time I'm using this lens in the manual focus mode so that I can select what elements I want to have in sharp focus.

In order to get high quality pictures a good tripod and shutter release is need to minimize any camera movement.

I have used it with the Sigma 2x extender with good results. While there is a slight diminishing of the overall quaility it is well with in the acceptable range.

I am very pleased with this lens, and at about half the price of the Canon 180 it is a very good value.

I would highly recommend it to anyone looking for a long macro, that doesn't want to spend for the Canon 180.

Very sharp and crisp optics.
Superb build quality.
Excellent bokeh.
The focusing is excellent for a macro lens.
Only problem is when the hood is extended it's hard to get the lens-cap off unless you have skinny fingers!
