影相的朋友,這樣到底算不算有問題^^, 是我的鏡頭或body有事嗎?? 有時發覺有失焦情況, 這幅在家外邊拍的, 連拍好幾幅了, 都差不多出現這情況?
用50mm f/1.8 lens
1. 日光室外
2. iso200, 1/4000s, f/1.8 單點對焦, 手持, 微風, 框框是對焦點 fine-jpg
發覺焦點有點下移到下面的那朵花, 但就算看下移那朵花也不是最好的對焦點.
反而要手動對焦才找到最好的對焦點. 這樣是有問題嗎......之前已經有過類似情況出現, 戶外日光充足下拍人像有層模模的感覺. 好像全幅相都沒有一個對焦點那樣, 但不是沒對焦, 是差一點點的感覺/..\

用 f/1.8 會唔 sharp
用 f/2.8 或以上會好d

手持不準,落腳架拍測焦板,或用尺代替

>>> . iso200, 1/4000s, f/1.8 單點對焦

日光光.... 睇張相.... 好似架機怏門速度"已去到盡" 但都係光左d

架機 有冇 1/8000s 快門...?
如果係得 1/4000s, 用 F1.8 要小心快門....
可能要用 ISO100... 吾係快門去盡... 張相都係過光.

是不是AF舊鏡,同現是G鏡對焦有分別,

Don't always believe your AF lens, sometime because of surrounding light, it wll make out of focus. You can use manual mode to adjust the focus. My camera has installed split focusing screening inside to check whether the focus is in or not.

支AF50mm,F/1.8 探完Nikon姐姐仔佢話無得整, 因為lens本身無motor, 所以無得tune, 佢話只可以靠我個body裡面個AF微調較番正喎, 仲加多句話師傅話我支lens真係有移焦..........^^"估唔到無得整

Yes it is 失焦

I guess it's nothing wrong with your camera.

Keep this in mind, when you half press the shutter release, it will lock in the focus for you. But I am assuming you are using AF-S while you took this photo.

When you are shooting object that will be moving around, including being blown by the wind, or moving kid, you've better use the AF-C instead. As the camera will continuously doing the focusing until you fully press the shutter release button.

Difference is AF-S will be the focus point around 1 second ago when you lock in focus and recompose the framing.

But AF-C will be focusing sharp right to the split second before you fully press the button.

so AF-C is very helpful when you try to shoot flower.

Hope this help out for you

Cheers,
