Bests & Worsts Reviews from Amazon

I've been using this lens extensively with my D70. It lets me shoot without a flash in low-light situations where other photographers are complaining about not even being able to focus. I'm often able to even turn off the autofocus light, which allows for very natural pictures: the subject isn't hit with an anti-redeye flash or focusing beam, so they don't flinch and change expression. It produces excellent portraits, with the background artistically blurred. Are there shots that I've gotten with this lens that I couldn't have gotten with the ($99) 50/1.8? Yes, a few. Most of them were from weddings (indoor, flash inappropriate, motion), or at night with no light sources within 20ft. For the vast majority of my pictures, though, the slower lens would have been more than adequate (even in dim light, I'm often shooting at f/2-f/4). If I had to choose between the two today, I'd probably get the cheaper lens.
