Found a Tamron AF 28-200 zoom Model 171D in the attic. The Pentax Digital Camera Utility reports this lens as FA 28-200 mm f3.8-5.6 AL IF ?
Request your critique on this lens and sharpness of the photos attached, as the Pentax Forum grades this lens 7 out of 10 - rather poor. I am hung on sharp optics, so based on your critique, I might sell this lens.
The K20D v1.04 was hand held. The camera settings are:- a) Av - Aperture Priority; b) Spot metering; c) WB - Auto; d) ISO - 200; e) Hi ISO NR - Weak; f) AF Area Mode - Spot; g) BRIGHT - Saturation 1, Hue 0, Contrast 3, Sharpness 3 Fine; h) SR - On, i) photos taken around 11.30 AM on a bright - overcast day, j) No AV adjustment.
All photos were resized from 10 MB using the Open Source Fast Image Resizer, which keeps the Exif data intact. My God the photos uploaded as just 50 KB.
Photo 1 - Ad Board: At 200 mm, 1/300 sec, f8
Photo 2 - Anushka: At 113 mm, 1/125, f8, in camera fill flash
Photo 3 - Staircase: At 28 mm, 1/15 sec, f6.7
Thank you in anticipation - for your valuable critique.
