memory stick 得佢用, 唔用等如認錯及成條 line 死得, 一如 Fuji 嘅 xD 咭。

其實依家同死左無分別, 對比SD卡又貴又慢
真係諗唔到仲有幾多人會買

遲早嘅事，十幾年前, Sony 死守 memory stick 已令佢損失唔小 DC market, 佢近年肯用 SD card 先至另佢番 ...

memory stick咁多年都未成氣候，如果佢d機只係support memory stick的話，等如自掘墳墓

未有USB3.0 reader之前，MS Pro Duo都算ok快既，最快果隻有50mb/s reading speed，價錢亦唔比當年既Sandisk Extreme Pro SD貴。當時其實大部份Sony單反都用到CF咭，反而係比較入門既DC先會用MS咭。以前PSP都係用MS咭，可能當初Sony諗住PSP既Market咁勁所以對MS都有幾分信心吧。

其實A7R3 真係比A7R2 upgrade左好多咩 ?
見佢地用同一點 cmos, 一樣係 399點對焦點，不過排得開d 令覆蓋率由 45% 變成 60%(A9 係近700點 + 接近全屏覆蓋率)

10fps係好快，但 buffer無點加過，得 28張raw, 3秒唔夠就要等save....(A7R2 有 25張@5fps)

Pixel shift只可影固定物件，風景有野移動都會有鬼影 (pentax同 om都係禁), dr升到 15ev, 但因為用同一粒cmos, 所以呢幾樣應該只firmware層面的野


其他就主要係機手操作感提升，joystick, toucscreen, 大電，雙卡， 但個價錢就由而家扣哂coupon大約 15k, 提升番上 25k -_-

用一部賣左兩年嘅機去比較一部新機價錢？

5D3賣幾錢？5D4又賣幾錢？
D810賣幾錢？ D850又賣幾錢？
