索尼HDR-AS15采用Carl Zeiss Tessar镜头,这支镜头的最大光圈为F2.8,低照度表现还算不错。有趣的是其170度的广角端其实类似于一支鱼眼镜头的视觉效果,虽说在成像方面暂时无法与真正的鱼眼镜头相媲美,但花一千多块钱购买一个极限运动摄像机,除了满足日常的拍摄需求之外,还能将其应用到一些特殊画面的拍摄当中,也算是发挥到极致了。在这次山地自行车越野赛中,我们也试着将AS15固定在三脚架并尽可能的贴近地面,拍摄弯道为90度的赛道,所获得的视觉效果令人满意。 Sony HDR-AS15 Carl Zeiss Tessar lens, the maximum aperture of this lens is F2.8, low-light performance is not bad. Interestingly, the 170-degree wide-angle end actually resembles the visual effect of a fisheye lens. Although it is temporarily unable to match the true fisheye lens in imaging, it costs more than a thousand bucks to buy an extreme sports video camera. To meet the daily needs of the filming, but also its application to some of the special screen shot, can be considered to the extreme. In this mountain bike race, we also tried to fix the AS15 on a tripod and put it as close as possible to the ground, taking a 90-degree track and getting a satisfying visual result.
