Sigma 100-300mm f/4 EX DG IF AutoFocus Telephoto Zoom Lens for Pentax AF Cameras - USA Warranty

This lens has been my work horse for outdoors sports photography. Have shot 10's of thousands of photos with this lens over the last 2 years. The unfortunate fact that I have now had to send it in to Sigma 2 times for service. Warranty is 4yrs. So its covered. When it comes back it once again will be used exclusively for outdoor sports.

The lens is heavy, but that is what I expected with a constant aperture EX lens. The need was for a reasonably priced, greater than 200mmm, low light lens for sports photography and it fits that need. It focuses quickly for being a non-HSM lens. I am very pleased with this purchase.

After working with a cheeper zoom I was getting very frustrated with my images and with available zoom lenses for the Pentax 20D. I am very pleased with this lens! It is very sharp and now I can shoot with confidence my images are going to be of good quality. I also bought the sigma 2x converter and it works amazing too. Now I have a 100-600 quality lens. Nothing much wrong with it.

Get the 1.4x & 2x Sigma Tele-Converters, with the lens factor you'll get sharp shots out close to 1000mm. If it was 1 stop brighter it would cost twice as much, and be a lot heavier. I love how big the moon is when I Silhouette something infront of it, but use it mainly for birds. It's a lot sharper than I expected, especially with either of the Tele-Converters. I often use a polarizing filter to increase color saturation and find it plenty bright enough. P. S. I love my MonoPod and use it more often than my TriPod with this lens.
