I would really like to get into portrait and macro photography and recent got a Pentax K-x as a birthday present :D
I was looking for a budget lens that would throw up some nice results. I really like to add depth of field to my shots and the kit lens is a f3.5 – f5.6 only. I was looking at this little lens, second hand, but in good nick, cheap and a f2.8 50mm. It’s manual only but not an issue for portraits I think as I’d have a still image or barely moving image. I assume once clearly focused it would be quite fast and bright and create some decent dof.
K-x has pentamirror viewfinder. Not the best one for manual focusing. Lens is OK, however, I’d try to find something with AF like 50/1.7. These kind of lenses are very cheap in general. It won’t be difficult to find one.
The camera is very good though. Get some eneloop accus and enjoy photography.
