CBZ is better than Pulsar
if you want to get for birding or zoos you can get nikon 55-300vr tamron 70-300 vc or a nikon 70-300 vr
if you want a cheaper till 200mm then you can get a nikon 55-200 vr
there is a slight confusion on the Nikon 55-200 mm model: in amazon, the VR is printed in a different place than the one in ebay. Please guide as to which one is original?
