I have a MZ-7 with a pentax 28-80mm AF lens. I am in a quest for a telezoom and I've seen several Sigma, Cosina, Tamron and Pentax options at eBay. Since I'm bying for amateur use, has anyone any suggestions for a reliable and "relatively bright" telezoom AF between 80-200mm and 100-300mm :
Which is the most important technical feature that I should pay attention to in order to decide (apart from the cost, that is)?
I really need some advice and I thank you in advance. Bye !
