我有部50D連18-200Kit 鏡. 最近剛買了Sigma 24-70 2.8 IF DG. 影相時Auto 及pre-set 的 White balance modes (e.g. daylight, lightbolbs...etc.) 不比kit鏡時準確, 要用custom white balance. 正常嗎? Thanks.

Ching你點樣知道色溫唔準確？

[canlaymen]

晚間燈光下影完在電腦看, 色稍偏黃.

正常的, 色稍偏黃. 死馬特性嘛.

[petercyc]

夜晚燈光好多時係黃色. "不比kit鏡時準確"? 即係你支KIT都係一樣黃?定係差過支KIT?

Maybe the Quality of EF 18-200 is better Sigma 24-70.

BECASUE THE APERTURE SET TO VERY BIG LIKE F2.8 SO THE MACHINETHING THE THAT IS THE OTHER WHITE BALANCE

TRY SET THE APERTURE AS F4 OR SMALLER CHECK AGAIN
