most likely the prime will be sharper, lighter, smaller, better bokeh

and the zoom will be heavier, not quite as good IQ (but more than good enough for most) and will be far more versatile

personally I would go with the zoom

You don't say what you want it for. For very specific purposes the classic and superb Pentax 135 could be the right lens ... for everything else the Tamron wins hands down.

There's a big difference in size and weight there. In your case unless you need the 70-200 for a specific purpose (e.g. fast low-light sport shooting perhaps) then the 50-135 would, IMHO, be a better lens for you.

I use the superb Sigma 50-150/2.8 and there's not a hell of a lot of difference between that and a 70-200 (size and weight excepted). A bit more on the wide end is generally more useful than a bit more on the long end.

I will say that the Tamron 70-200 2.8 is heavy - for me. Monopod/tripod use only. I tried using it with my K5 and Battery Grip, and it was too heavy for me to hand hold. The price is too good to pass up. Since there are never any used ones on eBay, that should tell you something. B&H has a great price too. I read so many reviews about the Tamron, that I was a little scared. When I went into a store to look at one in Nikon mount, I was sold.

Too bad the store is a Canikon redoubt. I originally put money down for them to order me one in a Pentax mount, but because they don't carry anything Pentax, they never got around to asking Tamron for a single Pentax lens.

Basically the "Brick and Mortar" store didn't want my "Pentax" dollars.

Oranges and orangutans. Those are very different lenses, as described above. I don't have either, but I do have more than a few 70-210's and 135s (all MF), and I wouldn't mind either of those AF babes. I might even use them, too.

But you get to decide between small+sharp+fixed (F135) vs large+good+versatile (Tamron). Would you rather have compactness or versatility? That's the basic trade-off. We can't tell you what's best for you. Good luck!

It may not help, but I will add in that the Pentax F 135 is a great lens. Really sharp, nice colors, good contrast, and focuses close, too.

Ha ha ! A bit more than half the time though. You can always crop closer, like to see someone do that to get wider

Orangutan-juice just doesn't have the same bright fresh sparkle.
[It's like otter water. That's water squeezed from an otter. Ick...]
Also, the sexual activities of oranges aren't quit so disconcerting.
But we'll likely never see an orange co-star with Clint Eastwood.
