外置閃光燈問題
1. 我想請問一支外置閃光燈如果燒左, 係味成支廢左? or 可以修理?

2. 一支Sigma EF 500 DG Super 可以閃多少下(life)?

3. 呢支閃光燈話GN 50(m) = 165(ft) , 即是可以cover 幾遠? (主體與相機距離)

4. 買閃光燈,保養重要嗎 ? 容易壞嗎?

5. 我用緊Pentax K100d, 想買支閃光燈學野, 呢支OK嗎?

Thanks!!

1) change the head inside at CS can work again.

2) hard to say, before I Sigma 500 super used 4 months, then sent to CS to change the head.

3) GN50 is at only zoom to 105mm at ISO100, suppose use F4, it can strike to 12.5meter (50/4).

4) hard to say, my metz used over 10 years without problem, but Sigma..

5) I used Sigma 500super on DS before : output unstable, with milky diffuser is deadly unstable, FP mode sometime not work, display show strange signal CS can't fix... So you think think la

change head 貴唔貴? 保養包唔包 ?

Under warranty change head is free of charge.

Buy Pentax 360 or 540, 360 is ok for general use just flash head can't turn left / right, find from second hand market is around 1K

540 is a bit expensive, depend on whether you often use flash.
