MF turning the Pentax way, like the Tamron 17a 35-70mm

Just collected a Tamron 35-70mm which I need to get to know quickly as I'll use it soon at a wedding.
Tamron Adaptall-2 35-70mm F/3.5 Model 17A

Its brilliant as it focusses the "wrong way" like Nikon and Pentax, so that you turn the ring from right to left to get to infinity. It appears nice and bright in the viewfinder for a zoom. Looking at the lens diagram, it seems very similar to the M 35-70mm and A 35-70mm lenses.

I'll try it out on the tripod for pixel peeping performance, but the most important aspect of the lens is that it focusses the same way as my Pentax primes, so I dont confuse my small brain in the heat of a moment and focus in the wrong direction.

Does anyone know of other off brand, manual focus lenses which also turn the wrong way? I'd be interested to try some Kiron lenses if any of them do.

Right or wrong, my Sigma and Tokina lenses both focus the same way as Pentax.

And what's the philosophy behind putting infinity on the right or left, anyway? Coin flip?

Right? Wrong?

Non-manufacturer lenses are a mixed bag in this regard. Some focus right and some focus left and the pattern is not even consistent for a particular maker! (Tamron, for instance, has switched both ways over the years.)

cool, which Tokinas focus the right way...I am just seeking fuel for the LBA (I have to stop this, I have about a thousand negatives awaiting evaluation and potential printing)

My only Tokina is the SD 400 f/5.6, and it does focus the same way as Pentax (although the throw is much shorter than I'd prefer ).

I know the feeling: I enjoy planning and shooting photos a lot more than I enjoy editing them!
