小弟有支小白，想打雀，但無錢買大白，想加個2X頂住先！請各位師兄提供意見！

但聽好多ching講, 加左2x增距後, 成像影響都幾大~

自己就只係用 小小白+1.4x, 成像質數都唔錯, 影響很小~

I have 小白 IS 加左 2x 增距後成像影響都幾大 and also you lose a few f/stops. May want to try it out first to see how you like it before you spend the money.

I prefer extender 1.4x with the small white.
Extender 2x not only lost few f/stops, but also the photo quality and slower focus.

小白或小白IS一代就唔駛諗啦,用2x就真係差左好多,光圈最大係f/5.6.小白IS2代用2x就唔係差太多.

咁大白用咗1.4X後,會唔會冇咗AF呢?
