A16 及 Canon EF 17-40mm f/4L USM

請教各位師兄買邊支用好d?

主要影家中小孩約3歲

[Windsurfer]

A16 is good in price, F2.8, weight and size. Quality ok.
EF17-40 is L lens, good quality. More expensive, F4, heavier and bigger.

depends on what u looking for and what kind of photos u like to take.

我影小孩為主,佢成日四圍走,好似F2.8會易影d
但睇評語,EF17-40成像好似好d,但得F4
所以唔知點選好

走動小朋友, 室內F2.8都唔夠使, 室外有充足光線F4打上畫質會好D

[mingxm]

因多數在室內影,用F4會否有問題?

多謝提供意見^^

I have A09 with F2.8, but I seldom use F2.8, because the Len only Sharp on F4

For indoor, flash light can be used.

F2.8 allows 2 times of light than F4.
If all other setting are the same, F4 will require double time than F2.8.
If F2.8 with 1/50s, then F4 should be 1/100s.

I think the above should read "If f2.8 with 1/50s, then f4 should be 1/25s."

I agree that for indoor shots of moving child, flash should be used. F2.8 or F4 would not be very different when you use flash. If flash is not used, both f2.8 and f4 would not be fast enough for moving child. If child is not moving at all (which is unlikely), you will do fine with ISO800, f2.8 with IS.
