The DA 55-300 would be a good range for the zoo's shot, you can close in and zoom out. I love prime lenses, but it is kinda impractical for zoos. The DA stars are great lenses, but not being able to close down will be a problem at 200mm and 300mm.

The DA* 50-135 is a decent range depending on the zoo layout. On my last trip to the zoo, I found that I was shooting from 70-300mm depending on what the animal was, as they had allot of room to move around. But I the zoo is caged all the time 50-135mm may be a good range.

The DA*60-250 is an outstanding lens, but it's heavier and larger than I can comfortably manage. It felt more awkward than the DA*300, which is about the most I can comfortably deal with hand-held. I looked at the Tamron 70-200 f2.8 and it's a lovely lens, but pretty heavy. I ended up opting for the DA*200 f2.8 because it's lighter and I find it easy to use.

My answer was to have both the DA 55-300 when I want to go light and then use the DA*50-135, DA*200, DA*300 (or a mix of them) when quality is more important. That has worked well for me up to recently. Unfortunately, I made the mistake of shooting some comparison shots with the DA*300 and 55-300. I said I wasn't going to do that, and I really shouldn't have done it, because the difference made me want to put the 55-300 away and never use it again, and that's just not fair to it.
Well the Pentax 200mm f/2.8 is 825g and 134mm long compared to the Tamron 70-200mm f/2.8 which is 1.1kg and 194mm long , so the difference isn't that big

The Tamron costs €200 less then the Pentax .

This afternoon i went out to test my Pentax 55-300mm f/4-5.8

I've got an important shoot coming up in a few weeks , taking pics of friends riding there bikes on a speed circuit , so what is crucial here is AF speed , lens sharpness and 300mm reach

Pretty good for a cheap lens , would i get much better from a Tamron 70-200mm f/2.8

These were all taken handheld

focus speed looks good, a little work on the panning would be good. That is the issues with the last shot with the helmet.

from my research the tamron 70-200mm the autofocus really is not very good at all but it does have excelent sharpness - so for any form of action shots your gonna want the sigma 70-200mm if you want the f2.8 with its fast hsm autofocus

problem is that the sigma 70-200mm is now very hard to find as the new version with lens stablisation has arrived but its significantly more expensive than the old non stablised version

not sure what i am going to do to be honest =(

I heard that Pentax SMC-F 70-210mm is really sharp! You could buy at ebay less than US$200.

I myself just bought Tamron 28-300mm (185D) because some says it is a good sharp lens with proper calibration with the camera. I will try mine this weekend, I hope its true!

Cheers!
