Exactly as advertised.......2007-12-25

This little guy is compact and lightweight. I added it to my G series 70-200mm lens. A few preconceived notions I had were dispelled almost immediately. They said the f stops would need to drop by two by adding this. I thought I would have to make manual adjustments. I did not. When you power on, the lowest two fstops are removed as an option, and even in auto exposure, the pictures are exposed properly. Excellent shots with this fitted behind the G series lens.

One nice thing I did not know about is that they include a bag that fits this teleconverter snugly. I thought I would be stuck finding a really small bag to put it in.

False Advertising!.......2004-11-19

I bought the AMT NightStorm, expecting a high-grade optical device, but as it turns out I received a very poor piece of equipment. I was using it outdoors and the image quality is poor, and the images are distorted.
