There is no Nikkor AF lens that will work on other Nikon DSLRs and not on the D50. -- Floyd L. Davidson <http://www.apaflo.com/floyd_davidson> Ukpeagvik (Barrow, Alaska) floyd(a)apaflo.com

YMMV. I've had a set of Plane Quiet NC-6 for the past ~5 years, and I find that particularly when coupled with a pair of generic -28dB foam earplugs (just turn up the iPod's volume a little), the combination provides quite a bit of isolation from ambient noise...my habit is to now either try to lip-read the Flight Attendent's converation, or to be polite and pull them off. Of course, there's no particular airline policy of "...please remove passive earplugs..." - so they're pretty much just trying to apply the 80/20 rule. -hh

The D40, D40x and D60 do not have the autofocus motor in the body and so cannot use older Nikon AF lenses that require that "screwdriver" coupling. But the D50 is basically a lower-priced version of the D70, and it does have the AF motor in the body. It should work just fine with any Nikon-mount AF lens. > She's using the 300mm end to photograph birds about 20 feet away. The > photos are more satisfying than she'd get with the D50's kit lens Yes, I'll say! :-) > so she's happy for now. Good. Some people would not regard a 300mm lens as quite long enough for bird photography, but if she can get within 20 feet and the birds are not too tiny, that would be good enough. I had assumed from what you said about cost being an important factor that it was not that long a zoom. Now what I don't understand is, since it's an autofocus zoom, what exactly is the problem? You mentioned that you understood it would only work in a couple of modes. It should work fine on the D50 in every way, though if it's a low-priced lens without Vibration Reduction (Nikon's name for image stabilization), hand-holding it would be a big problem at the long end.

I've already been offended far too many times seeing your blurry, badly exposed, zero-composition, 6-year-old's snapshots. All which could have been done far better if you strapped your camera to your dog with a bark-activated shutter. There's no need to gawk again at some sad accident just to raise your hit count. Any increasing numbers now being caused by people that enjoy a freak's side-show act at a two-bit carnival. |
