套头比不上吧?
镜头群比不上吧?
对焦速度比不上吧?
套头比不上吧?
photozone的打分结果(光学素质)
NEX套头3星半, GF1套头(14-45mm)没给出分数, 但是从Analysis的结果来看MTF基本相当
但是NEX套头是镁铝合金, 双马达(多一个静音马达, 拍视频用)带防抖镜头
GF1套头是塑料的, 具体结构, 等等我不清楚, 希望老兄能提供
photozone的原话: ' Kit" zoom lenses have a rather bad reputation regarding their build quality due to the use of cheap plastic and a rather "laissez-faire" clearance between the inner lens tube and the outer lens body. However, the Sony lens is an exception to the rule here. Surprisingly Sony used mag-alloy for the lens body as well as the focus ring and everything's just as tight here as it should be.
镜头群比不上吧?
NEX兼容大部分的A口阿花镜头(可AF), 明后年将有7只镜头推出
包括一蔡司定焦, 一标准变焦G头, 一定焦微距, 一定焦人像, 一定焦中望远, 一变焦广角, 一变焦长焦. 镜头群应该不算差了
对焦速度比不上吧?
photozone的原话" The AF performance is pretty good for a contrast detection system (albeit highly dependent on the base camera). AF operations are basically noiseless. Manual focusing works "by wire" so the focus ring is not directly coupled to the focus gears but to the AF motor. DMF ("Direct Manual Focusing" in Single Shot AF mode) is supported. OSS ("Optical Steady Shot") is Sony's lens-based image stabilization mechanism. It seems to be on par with the Canon and Nikon variants (better than Panasonic's OIS).
对焦速度和CMOS面积有关系, 面积越大的对焦难度越大, 速度也会受到影响, NEX的对焦速度确实不如GF1, 差个零点几秒的样子好像
电池续航性比不上吧?
这个是个问题, 谁让NEX个头小呢, 电池体积也小了.
还有啥.post出来大家一起来讨论下下.
我比较相信专业评测给出的结论 |
