I have a Pentax MZ-5n which I use mostly with the Sigma 28-80 F3.5-5.6 Aspherical which I got with the camera. Photos seem to have less "punch" (particularly when the sun isn't shining) than ones I took on an MZ-50 with standard Pentax 28-70 lens.
I'm wondering whether that Sigma zoom is a bit too "budget". I'm tempted to replace it with a 28-105 internal-focussing (I just HATE that filter ring turning). Have considered Pentax, Sigma, Tokina and Tamron. Like the idea of faster lens, so Sigma 28-105 F2.8-4 very attractive, but Sigma again? Need to keep below 200 UK pounds (ideally). I've noticed that IF lenses seem to "whirr" more on focussing. Could the increased load on the camera auto-focus drive be a problem? I'm sure Pentax would say using anything but a Pentax lens might wreck the camera, but what is the truth? Thanks, John Leonard, Surrey, UK. - This message is from the Pentax-Discuss Mail List.
