hello every c hing ,I just brought a d300 two days ago and I found my d300 focus is quite slow when I am using both 50mm 1.8 nikon lens and sigma 17-50mm 2.8 .I also compare with my friend canon d40 with sigma 17-70 2.8-4.0.d40 is much much faster and my d300 on focus same thing .so any suggest ???or any setting I miss ?thx

試一下單點對焦@af-s

師兄建議你用返D新鏡 例如有超聲波馬達 HSM等....追焦同對焦速度快好多。

D300 你未摸熟個對焦模式，一般用重點對焦模式而最高51點比較小用.

買本書睇睇 !

用連拍模式有需要時按動機身Ｃ制持續追焦。

D300 係–部專業級相機，裏面有好多sitting 係可以調較給不同場景。
若果你係新仔未玩過單反既 話相信要多花點時間去摸熟部機.
你放心啦 D300既對焦糸统絕不遜色於40D.

d300用既對焦糸统係nikon目前最高級架啦, d3x 六皮幾都係一樣

I fixed up problem.It is because I set up with a high ISO NR.I am using off now and focus much faster

同 nr 無關o架喎﹐心理作用吧。
