Default 70-200/70-300mm Sport Lens Info Wanted

I am finally in the market for a good sports lens. I have a Pentax K-5 and K-5ii. Looking for a good 70-200mm or 70-300mm f/2.8 or an f/4 nothing less than f/4. I already have an 18-250mm f/3.5-6.3 and I find myself using the 200-250mm range of the lens alot when I do sports so leaning towards a 70-300mm........

I have been having trouble locating what I want. I have a budget of $1100 now or I can wait ad can add up to $100 for each month I wait.......

What do you all recommend for the Pentax that mounts on a Pentax. I have heard both negative and poitive thing about the Tamron and the Sigma and not sure what to believe. Anyone with first hand experience. If you do not uses these lenses for your sports shots let me know what you use.

Main uses High School Football, little league baseball, local tennis events and some wedding work, but more for sports. Quick focus a must sharp images a must......

Current lenses Tamron 28-75mm f/s.8
Sigma 18-250 mentioned abve
Pentax 50mm 1.4

Thanks in advance

dave

Right now the sigma 70-200 2.8 OS is the only real option. Tamron makes a sharp lens but it is slow to focus. The sigma will be great for wedding work. There are some issues though:
  1. Sigma quality control just isn't as good as OEM. So, you want to buy from a place where you can exchange for another lens if the one you get has focus issues (which seems to be the biggest problem with sigma lenses - front/back focus issues).
  2. 200mm lens is good for about 25 yards of coverage for sports. That can work for football (works better for that than soccer or lax) but you're still very limited to middle of the field and toward your sideline - so plays to the other sideline are too far away - and when the line of scrimmage is between the 35s you can have issues because of the player's area. For baseball, you need to be shooting from on the field and you need a smaller field. Once you get to a full size diamond, 200mm is too short even if you're shooting from on the field.
  3. Some people will say use a TC to get more reach. I've never been impressed with the photos of the 2 sigma lenses I owned (70-200 2.8 non-OS and 120-300 2.8 non OS). I suspect it was also partly because of the quality of Sigma's TC. I don't know if they've come out with a new TC in the last 4 years.
If you're shooting night games and want a lens for weddings I don't see any other options because you need f/2.8. And, as of right now, the sigma 120-300 2.8 isn't made in Pentax mount.

Out of curiosity if you have a 500/4 why not use it for sports? Or at least have it on one of the bodies for when you need extra reach?

I believe it's a typo - there is no 500mm f1.4 lens. Such a beast would be huge. I'm guessing it's a 50mm 1.4.

That would make sense. I figured something was a typo but figured the wrong way.

The Sigma 70-200 coupled with the K-5 is a great improvement over the performance on earlier camera bodies from Pentax for shooting sports. The K-5 gives you more headroom on ISO and improved focus performance, but it's still not a speed champion. You definitely need the f/2.8 for night time sports.

The more research I do between Tamron and Sigma the more I am led to Sigma. I just have to wait about 6 to 7 weeks more to get the extra funds needed to make this happen and then will be getting the Sigma 70-200mm f/2.8 with Pentax mount.

Also the more I look at the 70-300 (f/3.5-5.8) the less it looks like a great lens and the 70-300 is too heavy and pricey for me. I may keep my 18-250 to have the extra reach as a walk around lens.......

John G and others thanks for the very good info you provided for me
