I'm slowly looking for a decent Macro lens. I love taking macro shots with my old SMC 28-200 but it's not really a true macro. I am looking for advice on a good dedicated macro lens that won't break the bank.
Any help?

I've got the Pentax SMC-M 100 mm f4 Macro and I'm very satisfied with it. It's up for sale now and then on e-bay and not irresonably expensive.

Others on this board praize the Vivitar Series 1 100 mm Macro lens, but I think that one is pretty much more expensive now (if you can find one) when the word has spread.

The best deal during the last 2 weeks came from KEH . There were two F100mm2.8 Macro at $165 - $260. As usual it was gone probably within a few hours. Now there is not even any Pentax AF prime at all.
Keep looking.
The next one is probably DFA100mm2.8 which costs more but readily available. These are all 1:1. Pentax macro M100mm F4 is cheaper but it only takes 1:2 .

Edited later: I got my FA100mm2.8 the same way from KEH 2 yrs ago. Their Bgn rating is real bargain

just about all of the macro lenses you find will give great results. differences in the will be build quality, AF, and magnification. you want at least 1:2 mag, 1:1 is even better. you also probably need to do some research.

Roy, what was that fly taken with? Did you do any extra editing to it?

In general, how do you know if it's a 1:1 lens or a 1:2? And is the F-stop as big a deal on a macro lens? ie - is 2.8 compared to 4.6 going to make that much of a difference?

Thanks for the info everyone, looks like I need to keep my eyes peeled for a good deal.

actually that one was taken with a reversed 50mm lens at f16.
widest aperture doen't make that much diff because you'll want to use f8-32 for the DOF you need taking macros. the specs of the lens will tell you what it's mag is. it's also usually displayed on the lens. a 1:1 macro will never be a zoom. most people like the 90-105mm range for the added working distance over the 50mm.

do your research.. ask here if you find something you like. here's a 1:1 with my vivitar s1 105mm f2.5 (also known as kiron,lester dine, panagor, elicar)

The Kiron 105mm 2.8 is definitly a keeper. Becoming quite well represented on this forum


Max aperture won't make a big deal for macro shots, but if you like to use it as a portrait lens too, it might come in handy...

What's the deal with extension tubes compared to teleconverters? I know you loose some f-stops but is that all?

Also if a lens says 1:2.8 or something along those lines, what does that mean?

1:2.8 means that the focal length divided by 2.8 gives you the size of the opening of the diaphragm....i think...
