Great lens for Close up work. This lens lives up to the high standards of all the other limited series lenses. I have done, more than a few, stacked images with this lens and I am more than satisfied with its performance.High Iq, color, resolution and all other aspects of the images are superior.

I have used this lens for different applications.Mainly to shoot my small scale sculpture. It has the correctgeometry to better illustrate small distances and render smallobjects with a three dimensional emphasis.

I bought this lens when I bought the Pentax K-1 in November 2017. There is a little corner vignetting in full frame mode that is easy to crop. I use crop or square mode with no problems. Excellent lens and camera for wildflower photos. Good macro depth of field.

My son using and enjoys the results

A delight of a lens. The haptics are great and I never had a sharper lens in my live. Autofocus is quite slow on my K-5 but still good fro a macro lens.

Nice sharp lens!

This lens is small, light, well built, macro, corresponds to a standard lens on an APS-C camera, and is very, very sharp already at full aperture. Cherries on the cake, it takes 'Pentax standard' 49mm filter, and it has a very convenient hood built-in. Cannot ask for more than this.

Sharpest tool in my bag. Great for macro and as a prime 35mm lens.

I am not a native of beautiful Colorado, but I got there as quick as I could! I only mention this because I moved from the second most beautiful state in the nation, Minnesota , eight year ago.

This metal Macro lens on a DX body offers approximately a standard 52mm focal length in full frame terms. Excellent build and image quality.
