Why not recommend the pentax FA 80-200? Aberrations? That's funny i've never head a problem with that in any review i've read regarding that lens, and 99% of the people that own it, rave about it with almost no significant complaints.
Then you already answered your original question it would seem.

Maybe you misunderstood what Adam said? He said he didn't recommend the FA* 200 for sports, not the FA* 80-200. Quite the contrary, he highly recommended the FA* 80-200.

Mike - Do you really feel like the DA50-135 focuses faster than the Tammy70-200? I am not doubting you but there have been a bunch of posts talking about how wickedly slow the DA50-135 supposedly is. I am kinda shocked that its faster than the Tammy.

wickedly slow, really? I rented one for a week and shot low light concert work and I was not only impressed with the very obvious fast speed of the SDM, but almost didn't want to give it up and go back to my screw drive lenses, lol. I did not have both at the same time but my recollection was that it was most definitely faster to focus than the Tammy. Hopefully there is somebody who has both who will be able to compare these.

I will also say that of the hundreds of images i shot with the DA*50-135 and the DA*200, the IQ of all looked great, but not photo looked significantly better than the pics i am getting out of the Tammy. Obviously I had no side by side comparison, but as far as IQ is concerned, the Tammy is not leaving me wishing I had bought the Pentax.

That's funny i've never head a problem with that in any review i've read regarding that lens, and 99% of the people that own it, rave about it with almost no significant complaints. One thing I've learned, if many people are raving about something, there's a reason. There's only a choice of 4 or 5 zooms here and the Sigma is out. For the crap users are saying about that lens, being sub par in sharpness, having purple fringing issues and a few other critical F$ck Ups, Sigma must think i'm crazy if i'm going to pay that much money for a lens they should have gotten right. It's ridiculous we don't have some of these lens optical, image and mechanical issues resolved. You can't tell me Tamron doesn't know they screwed the autofocus up on the tamron either. I'm convinced companies deliberately under-design products so that they keep consumers wrapped around their finger, so to speak. This just ticks me off.
Whoa now. The new Sigma is suppose to be much better in regards to CAs, sharpness, etc. I actually think that Sigma isn't asking to much for the new 70-200mm. After all it has OS and is still considerably cheaper than the CaNikon versions. Also, it's about on par (cost wise) with the older FA* 80-200mm.

The DA* sdm is a bit slower than the tammy's screwdrive (but quieter). I saw a comparison on dpr a while back and can confirm this through my own tests.

As far as IQ goes, the Sigma is great and all, but it doesn't quite beat the FA* IMO. I think it's because of the extra elements used to implement OS (which isn't much of a boon in itself).

Pentax really has some high standards back in the day, and it's a shame that the DA*s aren't making as much of a name for themselves.

The last 4-5 entries on this page appear to agree that the 50-135 is "slow"...but on the next page there are some disagreements. (Confuses the heck out of a beginner like me!)

No decent 200mm zooms?
Do some pretty decent primes in this range though.

Just for kicks I was thinking of doing a quick and dirty focus speed test of the zooms I have that have a 200mm FL.
I have the Sigma 70-200mm HSM Macro II (non OS), DA 50-200mm WR, and Tamron 18-250mm.
Figured I would do it outdoors with good light to give them optimal conditions for AF.
Since I don't want to spend too much time on this does anyone know if there is a common aperture and distance where AF performs most reliably or is it different for each lens?

I'm a cheap bastard. When I think, GOOD FAST 200MM ZOOM, I pull out my Vivitar-Kiron Series 1 Version 1 70-210/3.5 (US$33 last year, shipped). What, no AF? Pshah! CIF works just fine. And it mounts on my Spotty and K1000 and Prakticas too. And toting it is good exercise. For a prime, I pull out my Vivitar-Komine 200/3.5 with 18 iris blades (US$50 last year, shipped) and glory at the bokeh. What, 200/2.8 AF zooms and primes? Sorry, I'm a cheap bastard.

fwiw... i've got the older sigma non macro 70-200mm f2.8... and imho, it's a most capable lens, from 70mm to 200mm... i've shot at extreme 200mm very happy with results...
and sports, soccer, (handheld, not a lightweight lens)and find that the only limitation
is on my part...
a few pics...

Here is my unscientific 200mm zoom AF speed test.
Used what I have so the participants were the Tamron 18-250, Pentax 50-200 WR, and Sigma 70-200 Macro HSM II.
After looking at the video I do believe the Sigma was slightly faster than the other two, but not by a whole lot. The Tamron seems slowest because it has to move very little and takes about as long as the other two to do it.
The Pentax surprised me in that it actually has a quite a ways to spin but it does it in about the same amount of time as the other two.
