Review on Pentax K-Mount HD DA 40mm f/2.8 40-40mm Fixed Lens for Pentax KAF (Limited Edition Black) by Omar Malvo

This lens fills the gap between the DA HD 21mm and DA HD 70mm lenses. the same subject for all three lenses and took multiple shots with each lens. The IQ matched or exceeded the other two lenses. All three have excellent color rendering. The IQ of the Pentax LTD series is consistently high. And the price of 40mm was more than cheap.
