It was totally an impulse purchase, the 35mm f/2 SMC Pentax-FA AL lens I bought. I’d been toying with buying a fast prime for my Pentax K10D. Then a Black Friday email from Used Photo Pro pushed all of my buttons: the lens was already marked down and then they offered an an additional 15% off.
It is also the single most expensive bit of photo gear this cheapskate has ever purchased. Because of that, the bar is super high — I’d better absolutely love this lens.
I took this kit to Coxhall Gardens, a park in Carmel, an Indianapolis suburb. I harbored a fantasy of man rapturously bonding with machine to produce fine-art images for the ages.

Instead, I experienced a camera whose autoexposure frequently couldn’t find enough light to fire the shutter and a lens and autofocus system that often struggled to guess what I meant the subject to be. Even when it got the subject right, it sure hunted a lot trying to focus on it. Here, I wanted the pump to be in focus.

Here the K10D focused on the pine tree out in the mid-distance rather than the large tree trunk right in front of it. What the? I checked: I had multi-point autofocus on.

I drove home disappointed: I just didn’t bond with this kit on this outing. But I think I need to give it another chance. I’ve only had the K10D a few months and have yet to learn its ways. I remember that it took a few months to really become one with my beloved Canon S95. I need to give the K10D time, too.

It is, however, telling that the camera behaved better for me on my previous two outings: the first in Chicago with a 28mm f/2.8 SMC Pentax-M manual-focus lens, and the second on my October road trip with a 28-80mm f/3.5-4.7 SMC Pentax-FA lens.

If after a couple more major outings with this lens I don’t start to make it sing, I’ll probably just sell it. The great thing about lenses like this is that they tend not to depreciate. This lens in particular is highly regarded and should sell with no trouble for at least what I paid for it.

For fun I did a bokeh test. Here’s the lens at f/2, 1/500 sec.

f/4, 1/160 sec.

f/8, 1/50 sec.

f/16, 1/30 sec.

When the lens manages to focus properly, it is plenty sharp and offers reasonable bokeh.
I think my next trial of this lens will be on one of my Pentax film bodies — this lens has a manual-focus ring and should work great. If it passes muster, I’ll know that my meh experience here was not the lens’s fault, but the photographer’s.
