Lens for sports

I am new to pentax and want to shoot upcoming track meets. I would have used a canon 70-200 when still shooting Canon. I am hoping my 18-135 will fit the bill, or is this a good excuse to look at either the 100 wr or 55-300?

There are a number of suggestion for fast action sports, depending in which ones, but coming from a 70-200 (f/2.8 or f/4?) you may find the 55-300 too slow. The DA* 60-250 or Sigma/Tamron 70-200s may suit you better.

I can recommend both the sigma and the tamron 70-200mm's. The tamron is actually quite cheap ($799), while the sigma is a bit more expensive but also a bit nicer overall. The IQ is about the same (excellent).

Sigma 70-200mm F2.8 EX DG OS HSM Lens Reviews - Pentax Third-Party Lens Review Database
Tamron 70-200mm F2.8 Di LD Macro Lens Reviews - Pentax Third-Party Lens Review Database

I'll be putting a mini-comparison of these two lenses up soon, so stay tuned!

I'll have to second the Tamron 70-200 f-2.8. I don't think that you can get a better sports lens for the money. I used it to photograph my grand daughters Volley ball game and it worked out perfectly, especially when I used the Pentax AF-540FGZ flash to light the game.

If there was a vote, the Sigma for how quick it focuses.

For IQ, the 55-135mm gets my vote.

In the middle is Tamron.

I wont mention the negative points here because for others, they could be features.

For long distance sports like sailing, surfing and so on where you need more then 300mm then its either Sigma for your needs or Canikon.

I will say that I think that focus speed is a function of the camera, not the lens, so in my mind that takes that out of the formula for the lens.

If that is a function of the camera body then with every new body, the Sigma will simply work quicker then the body before last. I wont say a lot of Sigma`s IQ but its HSM technology is pretty quick.

All depends just how fast the people at the track meets are.

I guess, that all I can say is that the autofocus mechanism is in the camera and the scene recognition of the camera focusing system is what determines the speed of focus, I'd have to say that the lens just reacts to the camera's focusing sensors to determine how rapidly the lens locks onto focus.

How about using the 77? That would take care of speed and for high school track meets, I can get right down next to the track. Thanks for all the suggestions so far!

its simple...use your 18-135 at 75mm and see if the focal range works for you. at this focal range, do be careful and alert of incoming runners.

The 77 wouldn't do badly in terms of speed, but since it's a prime you won't have the versatility of zooming in those fast action opportunities from the same vantage point. For the same money, you'll be close to getting the Tamron 70-200, which performs remarkably well - only it's a lot bulkier and heavier than the 77.
