And yet - the G2 Tammy tested sharper at both 500mm and 600mm, and ........ is 300 grams lighter, and completely fine tunable on an individual unit/set-up basis, and cheaper !
This gives the advantage in reach and cropped photos to the Tammy. Pretty much the primary concern among birders.
The Niki 200-500 proved slightly better in the 200-400mm range, and of course it is a third of a stop faster from 420-500mm.
Most of my shooting has been at maximum focal lengths. There would have been a few curious birds where I've had to zoom out, the odd landscape at the 150mm minimum, and I think a solitary lazy seagull at the same length - maybe he thought I had some hot chips ?! :eat:
Getting close, with the lighting direction right, in good atmospheric conditions, with good technique and settings will see a blanket pretty much thrown over all these type of offerings in practical terms ...... :cat:
Hope Santa comes early for you !
Chosun :gh:
