Jess and I went on a photography trip yesterday. We went down gravel roads behind silos, cemeterys, and chicken coups. We found cows, and horses, and donkeys, and goats along with giant fields, bails of hay, and hard bright light from the West. All in all, we had fun.
But the best part was the new lens I bought on Tuesday — the “Sigma 18-50mm f/3.5-5.6 DC”:http://revjim.net/item/10512/. This lens is *outstanding*. I shot with it all afternoon switching only if I needed a higher powered lens and I am nothing short of impressed. The contrast is outstanding and it’s very sharp, even in the corners. It’s certainly sharp enough for digital. The range it has is fantastic for general shooting with a 1.5 cropping factor. It has a a healthy bit of distortion at 18mm, but certainly not any worse than my Vivitar Series One 19-35mm f/3.5-5.6. The AF is a tiny bit slow and a bit noisy. But, manual focusing feels great and the zoom ring has just enough give and take. For $109 it it well worth *every* penny and I can see no reason to hang on to the Vivitar any longer unless I ever wish to shoot film again.
I wonder if the Sigma 18-125 and the Sigma 18-200 are even close to this. The difference in cost is substantial (not in a pure dollars sense, but in relation to one another) over double for the 18-125, and over triple for the 18-200. But, with that kind of range, it would be well worth the cost. I only wish I could get my hands on one of these for a few days without having to pay for it. Granted, even the most expensive of the three is only $400, but, there’s no point in spending $400 on junk. Unfortunately, people aren’t really willing to rent glass as inexpensive as this.
