Reversing lenses can be very useful for macro photography - they allow you to mount a regular lens backwards, so you can focus closer than the lens would normally. There are some signficant drawbacks - since your lens is on backwards you need to be careful of the exposed more delicate end, and the camera can't control the aperture. There are several people here who have posted incredible pictures they've taken with this technique (and shown how you can make your own), but I've never been tempted to try it. I've opted for an extension tube and then an inexpensive macro lens, which works for me.

SMC, SMCP- the trade name for the Pentax multicoating on lenses

SMCP-M M-series lenses, K-mount manual aperture and manual focus

SMCP-A A-series lenses, KA-mount auto aperture exposure but manual focus.

SMCP-F F-series lenses, first auto focus K-mount lenses

SMCP-FA FA-series lenses, second series autofocus Pentax lenses, may share more information with the camera body. Some FA lenses also had power zoom (PZ) this feature will only work on the K10D DSLR (manual opertation only on other *istD or K100/110D cameras

M*, A*, F* and FA* lenses are the best of these ranges along with the "Limited" series of FA lenses. These are the lenses that poorer members drool over (myself included). Check out http://www.bdimitrov.de/kmp/for more information.

PowerZoom means that it's a two touch design with a two-position zoom ring. In the power position it acts very like a camcorder zoom - turn to the right and it zooms out, turn to the left and it zooms in. The further you turn it the faster it zooms. In the manual position it works as a normal zoom ring.

It also has some Auto features, such as two position focus, where it will jump between two user set focus points at the touch of a button, and it will automatically do zoom effects in one photo both in and out. The feature only works on the K10D and high end filme cameras like the PZ-1P and the MZ-S.

Thanks guys... Just another quick question... I love taking macro shots... but the kit lens doesn't do the greatest job... how exactly to the extention tubes work?

extension tubes allow to focus closer than usual giving higher magnification. if you want to use them with kit lens you need tubes which preserve automatic aperture because kit les doesn't have aperture ring.

ennacac: thanks
