thanks rummer

Be careful with cheap used lenses online. I would never buy a used lens without physically testing it out. If you spend $60 on a lens and it ultimately requires $100 to get it repaired, you just paid for the same amount as a new lens! If you are still interested in the craigslist ad, ask them exactly which model it is and the condition it is in.

rummer and cary,

thank you very much...coz i saw one in craigslist selling the af nikkor 50 mm lens and its only $60 so i was thinking if this would be a good deal....

definitely your feedback would be a great help...

The best bang-for-the-buck 50mm is the AF-S Nikkor 50mm f/1.8G. We just published a big article comparing 7 50mm prime lenses for Nikon F-Mount on the main blog. http://nikonrumors.com/2011/11/03/seven-50mm-prime-lenses-for-nikon-f-mount-compared-by-cary-jordan.aspx/

Your friend was probably reffering to the 35mm f/1.8G DX prime lens. There is no such thing as a 50mm DX only lens. All 50mm Full-Frame lenses can be used on DX, though.

bogs,

Nikon currently produces about 6 different 50mm prime lenses, but they don't make a lens called the 50mm DX. There are a lot of discussions in the forums already about the comparisons between some 50mm lenses, so it's definitely worth doing a search to get a variety of feedback on this issue.

From my personal experience, my 50mm f/1.4D has been a great match on my D7000. The autofocus is decently fast, and it is sharp for any aperture after f/2.8. The autofocus is noisier (louder) than the newer 50mm f/1.4G lens, and you have to flip the AF switch on your camera to go back between AF and MF. But the best of all, it's cheaper than the G models. If you get the f/1.8D, it's going to be even cheaper.

You should also look at the 35mm f/1.8DX as well. (This may be what you were originally talking about). It's much more usefully focal length for me than the 50mm on a DX camera like a D7000. The 35mm f/1.8 is the lens I use the most on my D7000.

Hope this helps.
