What would be the advantages/ disadvantages of using a 2x teleconverter with my Nikon 70-300 Lens? If I purchase a Nikkon unit will all functionality of the lens be retained?
These converters appear to be approximately half of the price of a Sigma 150-500 lens which is an advantage in its self. Also the total weight of the camera, lens and converter would be less than that of the body and the Sigma lens.
A lot of my time is spent in hides where the weight of the equipment is less important but I do like to get my boots on and walk the paths in search of my bird/wildlife targets.
All opinions would be appreciated.
Thanks
