我建議用flash.不需要太強.只要能keep住在安全快門內就OK.
NOISE的問題就不會太嚴重
個質數是不錯.個人意見是他不夠sharp(mayBe自己set得吾好)和color吾太凖(但很討人喜愛吔)
我只是幫公司買了部A70來試用過一陣.詳細還是得要問問其他A70的用家

其實a70係iso200 o既時候, noise就開始多ga la........小弟好少set 到iso200, 最多都係用iso100! 除非真係迫於冇奈la
小弟都曾經試過係朋友o既婚禮影相(hotel). 其實講真ar, 用iso200+埋f2.8係restaurant 都未必夠用ar, 可能都係around 1/20, 所以小弟好同意cnewshk兄o既講法ar, 用flash ar, 因為restaurant o既燈光真係唔夠ga, 除非有其他equiment補光la! 希望幫到你la!

ps: kevin兄, 我覺得a70晒出黎o既4r相好正喎, 我用直出ga, 同係自己電腦睇o既成像好接近ar!

Dear all
I have tried "internal flash" + ISO200 + f2.8 + P mode, but also so much noise is produced.

Do I use the wrong mode, or I should use M mode???
Please advise me

點解唔用iso50呢? 如果你係用"internal flash" o既話, 用iso50已經好夠ar
a70係iso50之下, noise係好少ga....你再試一試ar!! ^^

Thanks all of you.
But one more question, if I use ISO50 (A70) for taking photos in a restaurant at night time, will the background become very dark?

Hope for a soonest reply!!!

Because, I need to use A70 to take photos in a restaurant on Sunday

用閃燈背景因為曝光不足而變暗係正常,
或者你用慢快門閃燈喇(圖像有個人同埋星星),
最好加腳架set埋兩秒自拍喇,背景就唔會漆黑一片.

andy,

u know, A70 is a consumer level DC, so u can't expect much.
it's image quality and funtions may be the best among it's rival, but still, it's CCD is very small so noise level is high at high iso.

btw, there is quite noisy if u look at the original photo.
but it will be better in 4R print and resized. u may try it out 1ste.

if u really can't accept the image qaality, then use iso 100 + slow syn. But your hands must be stable enough.

Then.... Take photo in a restaurant
Which combination should I use
A) ISO200 + P mode;
B) ISO200 + shutter 1/30 + f2.8 (no stand);
C) ISO100 + P mode;

I feel very confused......

I have a A70 also. I use ISO 50, full power flash, Tv mode with 1/30 sec ( no need tripod and you can train youself to use 1/30 without tripod), foget about aperture and I get good pictures without too dark background. Because the 1/30 sec can "absorb" the indoor lights. I did try 1/25 and 1/20 and even more better! I think the noise is from ISO200.
