Originally posted by tasha_22 I have the option to buy this for $115 shipped. Any experience with this. I want this for wildlife and cannot afford the bigma or the 135-400mm.
It appears you have the K100D, while I have the K10D, so your results may vary. However, since I had a Sigma 28-300mm on a previous camera, I purchased the Sigma 28-300mm f/3.5-6.3 DG to use with my K10D. I quickly discovered this len just would not focus properly with this camera in most conditions, hunting back and forth for several seconds before finally giving up entirely.
After discussing this situation with Sigma, they shipped me the Sigma DC 18-200mm f3.5-6.3 and the other was returned. This lens does focus just fine with my K10D, similar to most super zooms in this class (not brisk but a decent compromise), and has since become my primary "everyday on the go" lens.
For most distant wildlife photography, I use the Phoenix MF 100-500mm f/5.6-8.0 lens. I purchased this big (over 20 inches extended), heavy (metal), slow, manual focus lens from a camera store going out of business, suspecting even the modest amount of money paid might be wasted. But the lens has since proven to be very useful, delivering decent results if handled properly.
