Every now and then, I have the urge to buy a professional lens because my compromise lens works up an itch hard to get rid of. I actually went on Kijiji and Craigslist to find a used Nikon 17-55mm f/.8. A used copy could go for about $800 or a bit less if one is lucky. Anyways, at the Henry's Exposure show this weekend, I had the opportunity to test out a Nikon 17-55mm and as I feared, I could not make the best use of it. Hand-held, it's not too easy to get a nice, sharp picture, and when I managed to get a sharp picture at f/2.8 there were some purple fringing (see below). It's not too much but there is definitely purple fringing. The Nikkor 18-200mm VR lens gets me a sharper picture, but not the image effects of an f/2.8 aperture.
