I added some better bad focusing examples to the Sigma 18-50mm review below. Also, I actually came up with a percentage for out-of-focus shots, for 18mm and the telephoto 50mm end. Go down near the bottom of the review page to check it out.
You’ve probably noticed I finally moved May through July home page entries to the Home Page Archives on the Nav bar. I’ll try to keep it a little more caught up from now on.
On a last note, I’m beginning the Sigma 10-20mm lens review now (I guess I’m a glutton for punishment) but I’ve used it extensively and it’s much better than the 18-50mm. Look for a review in a couple of weeks or sooner, and a comparison page to the Sony 11-18mm lens.
