小弟用d300 + sb800 選內置su4 remote
發覺支sb800次次都閃,但係有時同相機快門不能同步
(作機頂燈就無問題)
請問係唔係有野要set,定支燈 / 機有問題?
請賜教.

請睇清楚說明書

See my page on how to use remote flash. It's an incredible feature, and it's free if you have an SB-600, SB-800 or SB-900.

su4 remote 是感光足發閃光，因為機頂燈和它太遠，不能閃光。

Thanks all.

I've got it now. Using SU 4 is not right. I need to perform setting in the menu of D300 > flash > command vs the flash.

其實唔係咁。
su-4 o既有效距離可以比 advanced wireless lighting 更遠。

問題好可能係樓主係內閃用o左 ttl 。
ttl 有 pre-flash﹐過早令 sb-800 同步﹐真正閃時回唔到電。

su-4 唔係唔o岩﹐都一樣可以﹐只係設定有唔同。
