Is the APO version of the Sigma 70-200mm F/2.8 EX DG OS HSM worth the higher price?

Hey everyone. I've been looking for a F2.8 70-200mm (or something similar for sports photography) and found these Sigma lenses:

Sigma 70-200mm F/2.8 EX DG OS HSM
Sigma 70-200mm Pe F/2.8 APO EX DG OS HSM FLD

I also found a Tamron equivalent, but according to some reviews, the focusing was significantly slower than the Sigma.

Would the APO version be worth the high price (almost twice as expensive)? Or are there better lenses available than these?

Thanks!
Stefan

I'll be curious to hear responses to this as well. Was a little sticker shocked when I saw the announcement on the main page here that the new Sigma 70-200 would be $2,400!

I think that you need to check the listings closely. I don't think sigma is making a non APO version of this lens

My Tamron focuses about the same as my other lenses. And, if it is in the distance ballpark, it should not present an issue. My bigger Sigma with the HSM takes some getting used to as I miss the grind and groan, and really have to "look" to see if it has focused :-)

As long as Adorama still has the OS version in stock, and I have the time, I'm going to take my Sigma 70-200/2.8 HSM II there tomorrow to compare to the OS version.

I would (and did) steer away from the OS version for Pentax simply because I have great SR in body already. SR in lens adds to cost, bulk, and weight.

As lenses Canikon needs OS in lens, and Sigma has made the jump to put OS into their lenses, I'm betting Sigma made the decision to save on design & re-tooling cost and provide us with a redundant OS solution. I don't think many Pentax owners will be buying it.

ive another thread about this lens..I want the OS version not for the "OS"..but for the IQ of the lens...DP review has reviewed one in a canon mount and it dumps on the previous HSMII vesion..{ which I have }

is it worth the higher price though...??....I wish they did a Non OS version for the pentax bodys, as sigma have done in the past..makes it cheaper for us..but alas not this time round:{

Were the reviews of the Tamron you read for Pentax mount? If not, then you can't make any conclusions on the AF speed as the Tamron in non-Pentax mounts uses an in-lens AF motor. From what I've read, the Tamron in Pentax mount has decent AF speed (and it should get even better when mounted on a K-5). That said, the new Sigma could be a knockout in this department.

I tried the Tamron 70-200 instore..the AF was decent on the K7...but nowhere near as good as the Sigma but better IQ with the images that captured on my memory card... as I bought mine mainly for sport the sigma took the gong....

Something has come-up with one of my dogs requiring a trip to the hospital this afternoon. So needless to say, I won't be doing the comparison today. I still hope to tomorrow. If not then, it may be a few weeks.

I did some more research and it seems they don't have a non-APO version indeed. I came across the links below and can't really figure out why the price is a lot higher on (I think) the first version (first link).
The II version is cheaper (second link), but doesn't have OS (don't know if this is usefull at all for Pentax users), no rounded aperture blades and is 1:3,5 compared to 1:8.
Don't think these things will justify the price though, or I'm missing something.

The links (in Dutch though):
Sigma 70-200mm Pe F/2.8 APO EX DG OS HSM FLD (stabilizer) - Pentax (AF), met 3jaar garantie, Nederlands - alle bekende merken voordelig kopen bij Kamera-Express.nl
Sigma 70-200mm F/2.8 II EX DG APO macro HSM - Pentax (AF), met 3jaar garantie, Nederlands - alle bekende merken voordelig kopen bij Kamera-Express.nl

m8o, would love to hear your findings if you can try it out! And hope your dog's doing okay. How's the K-5 by the way?
photogerald, the Tamron-review i read was tested on a K20d. don't know if it's faster on the K-7 which I use

You are paying much more in the 1st link because it has OS -- Optical Stabalization -- built-in I imagine. Better glass with lower CAs can't possibly account for that cost difference. The 2nd link it to the HSM II version of the lens, which was pre-OS and that I decided to buy a few weeks ago before Sigma stopped manufacturing it and forced us to pay for the needless OS. It's why I said what I did regarding buying it for Pentax; the OS built-in is redundant, adds weight, and adds cost.

Granted, the lens is supposed to have slightly lower CA. ...but near double the price? We owners of a camera body that have SR built-in with the effectiveness of the newer Pentax's are being forced to waste our money something we don't need because Sigma wants to save of design and re-tooling cost for a version w/o OS.

To answer your other question. I expected my K10D to be magic and something that was far "better" than it was engineered to be; before I knew much about all the D-SLR models offered by all the manufacturers. It turned out to be very good, but with many many compromises. The K-5 comes close to everything I wanted from the K10D. If you haven't seen this yet, I sum up what matters the most to me in this thread about the subject in the title:

It's plenty sharp ... if stopped down. I'll give you there's softness, more than I'd like, wide open. f/4.5 seems to be the ideal compromise between sharpness and speed for me. I thank my lucky starts K-5 performs the way it does with bumped-up ISO. I'm seemingly fine never shooting with it @ f/2.8 but having that light coming into the mirror box for focus ; tho I'll admit I'm a fickle soul so I'm curious to see how I feel about it in a few weeks, months, or years.
