Hello all,
I am getting on pretty well with my Pentax 645D, mostly using 6x7 lenses and an adaptor (though I do have a couple of 645 lenses as well). However, one thing that I am finding is that I would like, on occasion, to use the camera more speedily - with zoom and autofocus. I am looking for authoritative advice on the optical quality of the various different zooms. Having invested in the body, I am eager not to throw the advantage away by using an optically substandard lens in the pursuit of speed - that would be illogical! I recognise that there will be some compromise in quality compared to a top class prime, but want the lens to be pretty damn good nonetheless - throughout the zoom range and at all apertures.
Can anyone provide me with guidance on this please?
Best wishes,
Ed
