Macro photography: totally lost please help


when I get my k100 or k10D I definately want to go macro, but I know nothing about it.

I realize I need a fixed focus lens, but which one? what would be the difference between a 50MM or 100MM as far as how close up you can get (both distance from the subject and how close the focus can be)
I am interested in some insect photos as well as things like flower/plant close ups.

also, I would like to have the lens double as a good portriat lens as well, as a big $ investment I would like to get the best of both worlds as possible.

Do I need extensions as well for close up macro? do they exist for K100d and the soon to be K10D?

thanks for all the help so far

From everything you've listed, sounds like the 100mm macro would do the job.
Keeps you back some from the subject and could double for the portrait lense.

Ext. tubes work and will get you closer. Your in manual focus mode only. I have the Kenko set and information about the lens is sent to the body thru them.

For highest image quality, a macro lense or tubes give you the best results.

A good zoom can be used with the tubes, acts like a rail system.

tubes or a add on diopter element will be the cheapest way to get into macro, costing around $20-30 second hand for tubes (I picked some up over the weekend) or for new diopters. a third way is use a reversed lens 50mm prime lens (either attached to camera body by a reversing ring, or attaching to a lens using a coupler ring). using a reversed lens i think it magnifies beyond 1:1 but DOF is so small its hard to get it right.

the trouble with these methods is that you have to focus really closely, ie put the camera right up against the subject. (not useful for insects). I dont have a macro lens but i do believe that a true macro lens can reproduce up to 1:1 even if you are a meter away, and this is controlled on the lens which has a scale to allows you to magnify from 1:4 to 1:2 to 1:1. is this correct?

A macro lens basically just has the extension tube built in.
