would sigma 150-500 f5/6.3 enough for birding? do i need a TC ?
pls advice, i m shooting with d200
many many thanks
The most is only a 1.4x TC since 1 stop light loss from f6.3 is quite alot. A body with better iso performance might get better with the combi of 500f6.3 + TC. but no guarantee wide open at 500mm is tad sharp.
