看樣子,真的很強悍
與200-400 有得比了,雖然在銳度上稍梢弱了些(我猜想的,如果真如作者所說的話那200-400可能會有便宜貨可撿),但考慮到手持和c/p值後,真的很不錯說。
重點是作者說:
400mm and 1/10sec, handhold
-Colours and bokeh maintain as they are without TC

-AF speed remains very fast


-when I put my new teleconverter on this lens, I was very surprised nothing changed. The same sharp pictures but now at 400mm.



只希望開出來的價不要太高就好了

ps:就等作者的室外照了(望遠部分的畫質表現)和與200-400的評比了
