COMPARISON-PENTAX-QUANTARAY

On a previous thread PENTAX 18-250mm VS QUANTARAY 70-300mm@250mm
I compared the two lenses set for distance shots.This time I set up my subjects at 15ft distance. The Pentax 18-250 was set at 250mm and the Quantaray was set to give me the same size image. In this case it was 180mm on the Quantaray.At 15ft the Pentax even though it's set at 250mm because it's an IF lens gives you the equivalent of only 180mm or so.The further from your subject the more the lens behaves itself and you don't get shortchanged on your mm's.Anyway to me the results look pretty much the same.The sharpness and the colors seem to match pretty good.When i eventually get my "Bigma" it will be interesting to do some comparison photos. I hope that I won't be disapointed.--charliezap

The Pentax looks to have better contrast. I'd be interested to see them compared at f6.3 if possible. Which Quantaray do you have, Tamron or Sigma?

It's the 62mm so i think it's the tamron
