Got myself a new lens recently. A Canon 400mm F5.6 from Tanvir. This has given a new boost to my photography. The lens is razor sharp as I understood on the very first day of field trip. Went to Rajarhat. Though didn't find anything much beyond a few paddyfield pipits, Bengal bushlarks and Indian silverbills but the lens test was very satisfying. I got really close to this pipit with the lens mounted really low on the tripod.
