i recently switched back from canon to nikon ( d700 ); best thing i've done for the last years; in my "analoge days" i used nikon and kept all my equipment; however i had to get some new lenses too and started with the standards 24-70 the 50/1.4, 15mm (sigma) and a "cheap" AF-S VR Nikkor 70-300 4,5-5,6G; as i didn't wanted to invest in some "serious" tele yet. the lens behaves quite nice though, better than i expected for that price, zoom is fast IF is really good but there are some issues with metering with this lens; every single picture i take is overexposed by about 3 to 4 stops; i "overrule" that by stopping it down, but that's no solution ?! so my question is : did I miss something ? metering mode doesn't make big difference; i even tried the lens in "P" mode ( ev compensation is set to zero ) -> same effect; reinstalled the firmware twice and reseted all my settings, didn't help ? all my other lenses even the fish behave like expected only this lens troubles me. so being on nikon again for only about 10 days maybe it's my fault; has anybody an hint for me or is this lens dead ? regards.
