Message: <blockquote data-quote="Neil" data-source="post: 1622244" data-attributes="member: 1568">Finally got the Nikon 1.7x AFS Teleconverter out to the local park today on the Nikon 300/2.8 AFS VR.  I had read in several places that the best results from the 1.7x come when used with f2.8 lenses.  I had tried it on the 300/4 and 500/4 previously and hadn't been that impressed.I did use it today with the VR switched on which I don't usually do as the pollution levels were high and the light levels were very low.  I needed iso 800/1600 .  I used a monopod and the distances were 5 metres to 22 metres.Focus speed was fast ( felt as fast as the 500/4 AFS ) on the D3 and it was easier to manoever than the 500/4 mm .  As it's lighter than the 500/4 I might be using it more in future.Here are a few from today, Neil.Hong Kong,China.Oct 2009</blockquote>
