Pentax K Lens Tests
Lens Reviews - Pentax
Please note that the tests results are not comparable across the different test systems! This also applies to the 10mp (K10D) vs 16mp (K5) tests here because of the different AA filter characteristic between the cameras!

Please visit our Pentax Forum if you want to discuss a review or other topics!
