Comments about Sigma Sigma 100-300mm f/4 EX DG IF AutoFocus Telephoto Zoom Lens for Pentax AF Cameras:
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.

Comments about Sigma Sigma 100-300mm f/4 EX DG IF AutoFocus Telephoto Zoom Lens for Pentax AF Cameras:
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.

Comments about Sigma Sigma 100-300mm f/4 EX DG IF AutoFocus Telephoto Zoom Lens for Pentax AF Cameras:
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.
