Hello all, I will be getting a 5D2 with my tax return (extremely excited!
) and I'd also like to pick up a macro lens with it. I'm looking at the 100 L and Sigma 150 OS. I currently have a 24-70 L and 300 L. I also have a 50D.
The Canon is cheaper, especially if I buy it with the body. The discount is doubled through early March. The 100mm focal length is probably a little more useful in general. It is also sharper in the center.
The Sigma has a bit longer MFD, less CA in both directions (I hate CA...), and more uniform sharpness throughout the frame, at least on the charts. However, I didn't really find the 100mm focal length useful on a crop body, which is similar to the FOV I would get with the 150 on FF.
The lens will primarily be used for macro, especially nature macro (bugs, plants, etc). Which one of these would you suggest I buy, given my current gear?
Thanks!
Canon 100mm f/2.8L IS

For stopped down work, I think the 100 is an easier focal length to manage, esp. on 5D2 where you have plenty of cropping leeway. I wouldn't mind adding a 180 OS to my collection, but I don't think I'd give up my 100L for it.
