 Originally posted by fahrus  I'm deciding to buy SDM 60-250/4 or HSM 70-200/2.8. I'd like to ask you, if you there is soooo big difference in the AF speed ? New zoom will be used on my K10D to take an action pictures of my dog... Can you advice? https://www.pentaxforums.com/forums/pentax-slr-lens-discussion/114743-da*-60-...ml#post1186784 It shows the lens speed, in comparison to the DA*16-50mm and the other video compares it with the DA 55-300mm. I hope it helps you decide. - Bert | |
