Customer Review: Just picked up a Pentax K20D but since entirely new to the Pentax line, I have ZeRo glass to go with it. Since one of the attractive features of Pentax is their dedication to backward compatibility, I wanted a quality lens I'd be willing to keep for a long time but also some major "bang for my buck"... more info
Customer Review: This lens is soft at F1.4, but sharp at F2. And it can handle low light. These I think, everyone knows already. But F1.4 is not totally useless. If you like experimenting with wafer-thin depth of fields, you can get plenty of interesting special effect shots. That is versatility for me.
