Hello Everyone,
My name is Raihan and I just became the member of this famous forum. I just started Bird photography not too long ago and using both my D7000/7100 with Sigma 150-600mm lens. Even though crop sensor giving me more focal length yet I found I'm lacking while I try to take a zoom shot of small birds. I was wondering if someone can confirm if I can add a Nikon Teleconverter with Nikon-Sigma pair and if possible which one would be the ideal one to get more reach? As far as i know Nikon offers three different kinds.
Please accept my apology if it's the wrong place to put this topic. Thanks in advance. Kind Regards. Raihan.
