I am currently waited on the weather sealed Sigma 150mm HSM OS.

I used the 150mm Sigma on my E-3 and it was really an impressive lens. HSM means that it is not slow like most other macro lenses. I want a lens that I can use for macro, but still be fast enough for people and telephoto work. The Sigma appears to fit that bill.

Just have to wait for the reviews.
I won't personally wait for the review, but I would definitely get one as one as it becomes available for the K-mount. looks like the Pentax version would take the backseat once again behind the Canon/Nikon version. gosh, I hate it when Sigma does priority market.

They have to go where the money is. Personally I think it is a good thing. Canon and Nikon get the first runs and if there is any QC issues they get worked out by the time the Sony/Pentax/Olympus mounts are going out. Or at least I like to believe that. As a long time Canon shooter I have bee weary of the Sigma AF. I have never bought a Sigma lens for my 5D. Actually the Sigma 50mm F/1.4 is the first Sigma I have owned. Excellent lens. I have used a few borrowed lenses on my E-3 and always had good results.

On APS-C, macro lenses shorter than 100mm can be very useful.

Consider the Sigma 70/2.8 EX. A 1:1 macro lens that can double as a portrait lens.

I find >=100mm too long for anything else than macro (on APS-C). It gives you a bit more stand-off distance while shooting macro, but that's all.

I'm going to try some macro + TC combo, and see how it would go. as well as some comparisons if one would just be fine with the other. lenses on mind are 70, 100 and 135.

any thoughts on the promaster spectrum 100 mm f/3.5 Macro? I understadn the limitation of a 100mm lens, but I like macro shots and will shoot a lot of them with the right lens. I'm curious about the quality/sharpness of the glass as well as a reasonable price for one in excellent condition. thanks!

Promaster is a marketing brand and I think it's almost always for Tamron lenses. So see reviews for Tamron 100/3.5 macros.

I believe in this case it's a Cosina (link)

I think it also sold as a Vivitar and a couple other brands as well. I'm not sure if the Pentax 100/3.5 was related or not.

I have that FA100mm lens, it's great. Heavy, but great. It's dead-on reliable as a zoom, too. It may have to throw that focus far but it's super-sharp. I use it pretty much exclusively on center focus because I'm usually trying to get insect pictures.

Plus, it looks odd and gets double-takes.
