Thanks for taking the time to do the comparsion. Seems that V1 is slightly under exposure when compared to V2. Can't really tell if V2 can give more detail unless we do some pixel peeping. (eg. a 100% of the 'STOP' sign in the carpark, the word underneath CVTC).
Hi Airconvent, thanks for the pics... hmm, probably if you have time (to trouble yourself again ;p) here is what I probably would do to compare both of these lens.
1. Take the same pic on 18mm at F3.5, and at F8 or F11, make sure same shutter speed/iso, crop 100% to pixel peep both photos at wide open and stop down. Crop at corners and centre of the pic.
2. Take the same pic on 55mm at F5.6, and at F8 or F11, make sure same shutter speed/iso, crop 100% to pixel peep both photos at wide open and stop down. Crop at corners and centre of the pic.
With this probably we can compare a bit on the sharpness and vigetting on the lens. Anyway the original kit is a pretty decent lens, I expect the new version to be better. Might need to test it on the K20D also to see how it resolve the details ;p
I think to make a valid "comparative test" the shots should not be shot using the auto pic mode and perhaps center weighted metering. Best to shoot manually so that the aperture and shutter speed settings remain the same throughout. Some of the exif for aperture are different.
hrm, the first few , v2 looks better, but mainly due to exposure - looks like yes, the metering is more accurate on the v2 than the v1 - which well, underexposes.
as for the later shots though, they look the same at this size. maybe the difference can only be told at 100% crop, or even with the k20d. after all, pentax was ok with leaving the v1 with the k10d (same sensor and megapixels as the k200d) - and the main reason touted for v2 was because of the increased resolution in the k20d ; correct me if i'm wrong.
