Got me a Sigma 150mm macro lens... (DIALUP WARNING)

Just arrived a couple of hours ago. Slapped that puppy on the camera and started clicking. Heavy beast (at least on a micro 4/3 body). Nice being able to have the camera 2 feet away from the coin and have nice high angles for lighting. Experimenting with lighting and angles will take some time, especially with respect to cutting glare. Can't use my Otts with this setup, so these shots were taken with fluorescents (am wary of the high temps of halogen bulbs).

I think I like the half cent the best because it shows the die clash
and I know how difficult it is for me to pic small brown coins

PS is this the Sigma AF 150 2.8 APO Macro EX DG HSM Lens that I see on ebay for $673?
PPS Everything is very well focused. Does the lens have excellent depth of field or are you just very good at getting the entire coin in focus?

The 1896 Morgan has beautiful toning.

Umm.... yeah. The lens is more than double the size and weight of the camera.
Question: Since both the camera and the lens have a tripod mount, is there any inherent advantage with respect to stabilization, to attaching the copy stand to one versus the other? I have the copy stand bolted to the lens at the moment, the one major advantage being that I can access the battery without unbolting the camera, as well as being able easily remove the camera from the lens, leaving the lens bolted to the camera stand.

And nice pics too.
<< <i>Nice pics. What kind of Macro were you using before and what camera? Do you recommend the sigma over an OEM lens? Got picks of the same coins using both lenses in the same light to compare? --Jerry

I was using an Olympus Camedia C7070 wide zoom (point and shoot). Pics were ok but lighting was always a b*tch since I had to be so close.
I'm a point-and-shoot guy with respect to my photography ability though, so I wanted a camera that was still easy to use for the novice, yet provided the ability to try different lenses. So I split the difference. The Panasonic Lumix G1 is basically a point-and-shoot that can use multiple lenses. Although the lens selection for the micro-4/3 format is somewhat sparse, by using adapters you can use Nikon, Canon, Leica lenses, etc., although you do lose autofocus capabilities with the majority of lenses (not an issue with macro since I manual focus everything).
Yes that's the same lens. I got mine for the 4/3 mount from B&H Photo. Wasn't cheap at $729.
With the f-stop set in the 6-8 range, it's pretty easy to get the entire coin in focus.
From all the reading online I've done, it seems that this particular sigma macro lens has a reputation for being extremely sharp; very highly rated: Ratings for this lens at FredMiranda.com. The one area where this lens falls down a bit, according to reviewers, is on the autofocus, when it's being used as a portrait lens. Since I don't use the autofocus, this is a nonissue.

which is very very small and cannot be captured via any other built in macro lens. Thanks for the research as well.
I will purchase one of these ASAP.
These shots easily rival PCGS true view photography. I still like the service they perform though!
How about some really nice toned coins when you get chance! The copper pics were excellent!
I also use the Sigma 150mm, it is an excellent lens.
congrats and those are some fantastic shots. Shooting RAW is awesome and something I rarely get to do since most everything seems to be in slabs these days.
