Description:
This is a soft-focus lens where the image softness is controlled by the aperture ring (the larger the aperure, the softer the image). The aperture works manually from F2.8 to F5.6 ("stop down" mode), and automatically from F5.6 - F22 (will meter at F5.6 in that range). This lens does not have the "A" setting on its aperture ring.

Since there are no reviews for this lens, and it's somewhat uncommon, I thought I'd post a brief one. Although I've had it for almost a year, I haven't used the lens enough yet to give more detail. However, on World Pentax Day this year I did get a shot that convinced me the lens has real value.

Here's that shot:

And here are similar shots from the FA31/1.8 and K50/1.2 which demonstrate that a standard lens, even a fast one, can't achieve the same effect. I also doubt a soft filter would have the same effect either, although I can't say for sure, since I didn't try.

If you click on the links below each photo, you can view them at a larger size - plus see additional comments that help in comparing the shots.

I rated the sharpness a 9, because when stopped down to f/8 or smaller it is sharp, demonstrating that it really is a sharp lens, just with a soft effect designed into it at wider apertures.
