This one should be fairly easy, taken with a crop sensor:

Not trying to sell anything. Just noticed that you had almost only K versions and an impressive number of them from 15 to 1000mm, thinking that you might have been persistant enough to get them all, but was too lazy to check myself.
It would be just awesome if you could some time post a pic of all of them together!
Yep I can do that, give me a week or so.

I'll give you a hint. One of you is partially correct.

This is a MF Pentax lens we are talking about here?

the softness of the bokeh looks like it's from a 50/1.2. Maybe a K version!

It's very close and doesn't quite look like a f1.2 to me - quite a bit of tulip is sort of in focus, but pretty soft...

Maybe 55/1.8, wide open?

I suspect this is motion blurr (very artistic such), so it is hard to judge DOF.

M50/1.7?

^ feel free to click the picture for a larger view


Some people have hit VERY close to the bullseye, but nobody is right on the money yet!

With the following hints, those of you who can do exposure math should be able to guess the aperture:

It was a bright and sunny day outside, around 1PM at 57 degrees North of the equator.
1/6400 sec
ISO 80


P.S. This lens is capable of having a modern Pentax camera control it's aperture automatically.

That should narrow it down quite nicely!
