Oops. Guess I uploaded the extra ones on FB not Flickr.

I put a few more up.

It's just more difficult to identify them on the K-3. On the K-5, I'd shorted out the aperture pin on the body so it would play more nicely with manual lenses. It wasn't the best for stopping down since the aperture lever isn't the same on M lenses as it is on A lenses, but I mostly used it with the 55/1.2 lens, at 1.2.

On the K-3, I didn't want to mess with it, so it just shows up as "unknown aperture." Some of the ones I uploaded probably aren't at 1.2. And all that assumes I actually remembered to set the focal length to 55mm in the first place... I probably have a bunch in there at 28mm and 135mm from the other two manual lenses I tend to use.

And of course, I just haven't taken as many photos since I got the K3.

Need to change that. And this lens, in particular.

Do recall that there are two different Porst 55/1.2 lenses, as well -- the f/16 and f/22 models.

For whatever it's worth, I have some porst shots here you should be able to see in full size. They're sorted by date, and I put a hood on it in mid to late 2014.

The K3 ones are mostly focused using live view with focus peaking, so they'll be a good bit sharper than the ones in the K5, especially the earlier ones before I got an ee-s focusing screen.

I'd say the first image is the porst, with a hood on. It would be more obvious without the hood because it would have a sort of milky quality to the light that is sometimes pretty, and often annoying. :) Also, at least on mine, the bokeh doesn't have that small ball effect, it's more streaks

I sanded enough of the black coating off my porst that it reads through. Conductive tape would probably have worked, too, but I was worried about it jamming up.

The hood makes a really huge difference. Did you get one that was long enough? It should be one intended for an 85mm FF lens, if you're using it on a crop sensor. And having focus peaking in live view helps tremendously, as well.
