Tamron 70-200 with K3

Has anyone had any experience with a Tamron 70-200 and a K3? I have read that the AF is a bit slow on that lens but am wondering if it's a bit snappier on the K3 or not. I am trying to decide if it's worth ponying up the extra dough to get the Sigma 70-200 HSM instead or if I'll be content with the slower AF speed of the Tammy. I do know that my 55-300WR can barely keep up to action shots so I'm assuming that the Tammy with screw drive focus wouldn't be any quicker?

Or how about tossing the 60-250 into the mix. Anyone who has tried it on a K3 have any idea if it's faster than my 55-300 WR?

Mine seems to focus faster on my K3 than it does on my K5.

Is it fast enough for indoor sports to get a decent keeper rate?

I have not used it for any indoor stuff, but I have gotten good results outdoors with no hunting and a pretty quick and positive lock on.

The 70-200 is a lot faster on a K3 than it ever was on my traditional K5. It's not even a close comparison.

I have had the Tamron 70-200 with a K20D, then a K-5, and now a K-3. The K-3 autofocus system is far superior, and I have no trouble with this lens for indoor sports (soccer, swimming, gymnastics). I use back-button AF exclusively, with AF-C and the center nine points selected. I'm sure the HSM on the Sigma will be faster, but the only reason I would trade up would be for the quiet motor.

Awesome. I think I'm gonna snag one. I have a line on a pretty decent deal. It's been a toss up between this or the 60-250 but those are hard to find and not sure how well it would do indoors being f4

I was about a hair off of selling my Tamron 70-200... but I pulled the ad from the marketplace until I could try it on my K3...All I can say is wow. The thing is night and day (as are all my other lenses) on the K3.

Well all I have for reference for a telephoto is my 55-300. I would like to know if the 60-250 locks focus any quicker or heaven for bit slower. I would hope the Tammy would be faster but if it is screwdrive it very well may be the same.

I know my keeper rate with the 55300 is very low for action shots. It would be interesting to see how the 60-250 does compared to it.

The in-depth review of the HD WR 55-300 did pretty thorough testing of AF between the DA* 60-250 and it, and basically the 60-250 should only be used for slow sports, like lawn bowling. I've photographed football with my manual focus SMC A 70-210 f4, and I believe Ron Hendriks has used his 60-250 for lots of sporting events, so if you already have that lens you could try it, but don't go out and buy one just to do freelance work for SI.

I don't have a K-3, but the autofocus on the Tamron is much faster than the 55-300.

My experience the 60-250 gave me much higher keeper rate than the 55-300. Seemed a bit faster focusing but I don't remember that it was drastic. I wasn't planning on shooting any action indoors, but the need arose and I immediately realized why everyone recommends 2.8! My 60-250 is useable @4 but is soft enough that I avoid it, so mine needs to be stopped down a bit. But even @4 I have to jack up the ISO too high for my taste in order to get fast enough shutter speed.
So I have now purchased a Tamron 70-200. @2.8 it is sharper than my 60-250 @4 (at least in the center - haven't tested anything else yet). I now need to get out to compare the two - esp with my 1.4TC - to see if the the Tammy can replace the Pentax. Don't want to keep both, yet want to keep both! maybe I'll rig the tests!

I was in the middle of the same debate, but mine was rather the sigma 70-200 hsm or the da* 60-250 for the weather sealing. There just aren't many sigma 70-200mm available.

I will try to find some kind of action shots to take in the next week if possible.
