Suggestions Please? Wanting to buy Telephoto Zoom Len....
I have been saving to purchase a telephoto zoom len, and wanted to see what everyone thought was the best options on the market at the moment. It will be a once off purchase, so I want to make sure that I am buying the right one.
I have a K20D and am looking for something like a Sigma 70-200mm F2.8 MACRO HSM. Is this the best option? Do Pentax actually have one at the moment? It will be replacing an old one I bought about ten years ago (Vitacon 100-300 1:5.6-6.7) - i just find its not fast enough!
I actually don't even know much about the HSM technology - so any feedback will be greatly appreciated.
Thank you!
