各位 ching, 我想請教, 我有支 AFS 18-200 mm f/3.5-5.6,
如果真係想加增距鏡用黎打雀,(因為AF 80-400好貴),可否加2X ?
或加幾多會合理D ? 請賜教.
Thx.

the quality of using 2X or 1.4X converter on cheap cheap zoom is waste time & $, for 2X @ 200 mm, you must manual focus a 400mm lens @ f11, can u?

Moreover the quality using a 2X converter is acceptable only @ 2 to 3 stops step down, that is f22 or 32, the diffraction problem will occur beyond f22, so cannot not have acceptable image....

My solution, at most buy a 1.4X OR use software to enlarge your photo

我不買增距鏡原因,質素變差

相信只能加KENKO 1.4X，在光線充足下，勉強有AF。

增距鏡都唔平, 要over 2K(nikon) ^_^

1828用不到3個姨仔，只有KENKO。

d增距鏡多數俾定焦用多
最平就70-300vr or 唔嫌質素差 500mm 反射

一般打雀入門都係 nikon x1.7 + 300mm 4 or sigam 50-500mm

"經濟又可行" use photozoom professional to enlarge your image
