Bryan Posted November 14, 2013 Share Posted November 14, 2013 I am becoming increasingly dissatisfied with the performance of the Sony 55-210, it's fine in the centre, but suffers from edge sharpness problems. I therefore warped out my aged Pentax 75-150 M f4 and Pentax 200 M f4 to carry out a comparison, to see if I should abandon new for old. Handheld from the top of an ex railway viaduct on a blustery day, this should benefit the Sony with its image stabilisation, but, using ISO200 and keeping the aperture at f8, the shutter speeds were high enough to avoid camera shake. Results here I've also posted a quick look at the Pentax 28mm F3.5 K, a lovely bit of kit Link to comment Share on other sites More sharing options...
