K-5 and Tamron 70-200?

Hey! I ordered my Tamron 28-75 and it will be here soon! Thank you for helping me decide which lens to get everyone!

I now am looking at the Tamron 70-200, but I am not sure wether I should get it or not because I have heard horrid stories about the AF... Can I get reccomendations for this lens? I will mostly be using it for portraits, but I shoot sports on the side (no profit involved) so I was wondering if the AF was THAT bad? any thoughts?

You should read the in-dpeth lens reviews:
Fast Sports Zoom Lenses for Pentax - 70-200mm Sigma & Tamron - PentaxForums.com

A very solid reference.

In terms of AF, the critiscism of the Tamron was on the noise, not on the AF itself: "As far as the autofocusing itself goes, it is about as fast as that of the Pentax"

Hope the link will help....

I picked up a Tamron 70-200 f2.8 a couple of weeks ago and really like it so far. The AF has been fine for me on my K5. I shot a couple of basketball games using it with no real problems. There were a few blurred shots but all in all the AF works well. It is a bit noisy so I will probably stick to using my DA* 50-135 for situations where the noise could be a problem such as in an auditorium. I am looking forward to using the 70-200 for spring sports such as baseball and softball.

thank you very much!! I would much rather have the Pentax lens, but the Tamron is much cheaper (nearly half the price)

I was wondering if I need to adjust the AF maybe? (this is what I have heard)

Does anyone have any experience with the Kx vs the K5 for focus speed? I have a Kx and a number of 2.8 zooms. I get quite a few blurry shots when shooting indoor sports. Just wondering if an upgrade to a K5 would be worth the expense.

I really like this guys stuff

In the above video, he says that the screw mount is plenty fast. I think I heard somewhere that the AF motor in other mounts isn't quite a good.

I love my Tamron 70-200, and with the K-5, I am amazed at how well and quickly it focuses (I was used to the K20D). It can be a little noisy, but then so was the K20D shutter. I'm getting some great shots with it.

Here are two examples with this combination.

problems with AF? i don't have any with my 70-200. Only thing i notice is when i miss, it goes all the way out and then back in which takes a moment, but not a deal breaker. As for noise, it is fairly loud, so if i were shooting a funeral, i'd go to MF.
Optics are stellar! bokeh is lovely. colors are beautiful. I love the lens and it was a fraction of the price of the alternatives.
good luck.

All telephotos I have used will do that on occasion because for certain subjects, if you move off the focus point, the alternative is infinity. Short lenses do the same thing but it isn't as noticeable because of the much larger DOF

Only real problem with the K5/70-200 combo is that Liveview is unable to properly focus...
