各位ching 好,,
我想問問sB 800之燈用係D90機度...
我用F2.8 AND F/1.8 光圈時, 係室外影相應該點SET ISO,
快門值??因為我試過係室外影爆到7彩~

另外係咪ITTL 都係自動已經DETECT 到去釋出適當的閃光嗎?
使唔使點SET 支燈的數值??

快門值??因為我試過係室外影爆到7彩~ 唔關SB 800事. 係陽光普照既時間用2.8 and 1.8唔用閃燈, 基本上已有可能爆. 再加上您用閃燈, 快門最快1/200S, 唔爆就奇. ^_^

另外係咪ITTL 都係自動已經DETECT 到去釋出適當的閃光嗎? Yes
使唔使點SET 支燈的數值?? No, all auto.

thx B and H ching~
最快1/200s , 係d90 ge 極限??
d700或上會唔會都係1/200s??

若果用唔著閃燈打板係咪最好的方法??

[B and H]

D90最怏快門係1/4000s, 但閃燈同步最怏快門係1/200s.
D700閃燈同步好似無限制, 可以去到1/8000s.

若果用唔著閃燈打板係咪最好的方法?? 呢個唔識答, 用唔用閃要睇情況, 好難有一條univeral既方程式 ^_^

I think that the faster is 1/250s. 1/4000s may be too dark. The SB800 cannot output fully at such speed.

I think that the faster is 1/250s. 1/4000s may be too dark. The SB800 cannot output fully at such speed. -----> c-hing, please read the sb-800 manual page 60 (Chinese version), this is so called auto FP flash syn. Of course, the light source is not from the flash itself. For example, in a very bright environment, if you want to use a large aperture, then the shutter speed will be as fast as 1/4000s or 1/8000s. You can still use the flash in such situation with D700. However, with D90, the shutter speed will be limited to 1/200s, and therefore, you cannot use large aperture in such situation with D90. This is what I understand auto FP flash syn and this function, as I understand, is only available in top model like D700, D3 or D3X, etc.

In fact, this is just what I understand from the manual because I have no money to buy top model. If any c-hing knows, correct me if I am wrong. Thanks! ^_^

Have you try the GN mode in SB800 with D90?
