I've been looking for a faster zoom in this range, but I don't currently have the budget for a Nikon, so I'm looking at third party zooms. I need to get one in the next two weeks before I go on a trip to SE Asia and I was looking at these because they can be had for between $300-400 if I get lucky with the used market. I was just curious if anyone had one of these and what are their feelings about it? I already have one Tokina lens, and I love it so I figure this might be something to look into. Also, does anyone know when they switched from a screw on metal hood to a bayonet style pedal hood? I prefer the bayonet style for obvious reasons. Any other suggestions for a decent zoom in the $400 range that will atleast hold me over on this trip would be much appreciated. I found a Sigma 70-200 for about that, but it's in "BGN" condition at KEH and that scares me.
