Not a big inconvenience
It's just a hollow tube that goes in between the lens body and the Adaptall-2 ring.
With a PK adapter it's much better to use an extension tube (or even better grab a set... cheap and practical).
I don't know how it does behave with the PKA version of the adapter, with electric contact. I'm curious about that, does anybody have a first hand experience?
Even if it doesn't misbehave (read: it behaves like with no extension ring), I would not mess too much with the PKA adapter. They are finicky...
Unfortunately extension tubes with electric contacts are not so common, and not dirty cheap like the all-mechanical ones.
Maybe some Chinese company makes them. I'd happily buy a set if I find a cheap one on the Bay.
I still own two versions of this same lens, the 52BB and a later one in PKAF mount but with the same optics (52E). Long ago I also owned the first version (52B).
I find the optical project to be great, after such long time it's still competitive with current macros in the same focal range.
The only problem is the in/famous light spot that sometimes shows up, due to inter-reflection between the back glass and the sensor cover. Though I never saw it using the K-1, not a single time... but I didn't use it very much, so I'm not jumping to conclusions.
I can say that the results were great, and that for the price it's one of the best film-era lenses on digital full frame.
You'll like it!
