我對影相一無所知, 為左買部dc就走去睇左好多書(我都唔想咁辛苦, 我男朋友又對影相一d interest都冇, 激死), 今日買左部v3, 我對焦0個陣見到個格, 對清楚先影, 而且又冇手震, 但都好矇, y呢? 仲有乜野係hot pixel? 開機先睇到架? 小妹在此多謝大家賜教

Although V3 have 9 point focus, but if the block is not the subject that you want to focus, then the photos may looks blurry ga ! Try to use lock focus and it may help ! Hot pixels is the noise (red and green dots) on photos ! You may call it is noise and it usually happend when you set the shutter larger than 1s ! But since V3 have Noise reduction function, this should not a big problem ! People usually use the computer software to check the dead and hot pixels !

如果你肯定沒有手震，可能係你影的主體郁了，通常你影小朋友可同寵物都會有些情況。
另外，如果現場光不足夠，鏡頭要開盡光圈，對焦的精確度也要求高了。如果再加上你用了長焦距，少少對焦不準也會出現很濛的情況。
最後，如果你的主體太近(少於57cm)，也會出要對不到焦，這時候要用花花模式了。
如果全部問題都不是，可請一些有經驗的人士試影幾張，都是不清的話，可能要找代理服務部了。
至於hot pixel，小弟讀書少，不知何解。Sorry！
