Thanks for the detailed information.
On Auto mode, the Focus mode is also using AF-S? I don't know auto use what mode or can we override, sorry
Probably like what celciuz mention about focusing on the side with single point. Did you focus on the side?
What shutter speed you're at and at what focal length (zoom).
Under low light, if the AF Assist lamp did not fire, then it's hard to get focus although possible (especially since you have candle light), you might see the focus working/trying to focus, you can keep try to half press the shutter to try to get focus. If you're zoom in and shake will prevent the focusing especially with single point focus.
I've tried focusing on very low light (dark room with very little light source (table lamp far away -, baby sleeping), shooting ISO up to 6400 (not using tripod) to get proper exposure but at high expense of detail and noise (not to mention tons of hot red pixels?); it's very hard to focus especially with AF assist lamp turned off and harder to differentiate colours at night, but still possible sometimes.
ok, will try again next time when free..light up my own candle..lolx
i have focus on the centre, AF-S. have double check as it is quite often my thumb unintentionally press the single focus point to other side >.<
anyway, i tink there are some limitation like what u said, when getting too dark, the difference of colour not too much, it will have focus prob. I think when manual is not permitted or trying hard to get focus, by no choice I will carry tripod and shoot in auto. Hope it can focus with the AF assist light.lol...
Currently practising to shoot in low light for my trip...do you think it is worth to invest on 35 f/1.8 for the low light condition?i have try both 35 n 50, 35 focal length suite me more for my usage..but still considering now, wallet painful after getting a kit
