Sony DSLR-A850

評測報告

實拍照片

a. 升級的對焦點
SONY的對焦點一向出名準，但不夠快。但A850的對焦速度已相當滿意了。
b. 高像素
很多人說像素夠就可以了。相信這些用家還未感受過高像素的威力! 高像素帶來極端的銳利度，且裁切空間大，創作更容易! 沖印8R都要800萬像以上了，1200萬像素裁切夠用嗎?
c. 操作
沿用a700的優點，利用Fn掣來控制大部份的攝影設定，相當優良。
d. 極短的快門時滯
不用多說了。
e. 明亮的觀景器
以往只有在旗艦級的相機才有的特大觀景器是攝影的一大享受!
f. 金屬機身
g. 機頂mon設計方便
H. 低ISO拍攝表演極端優良!

a. 快門聲響
b. 鏡群少(尤以ff鏡群，只有蔡、g，鮮有平鏡選擇)
c. 無預留機頂閃.....
d. 不是防水防滴漏設計

用後一年才寫出我對此機的感受，但它仍是我最愛的單反之一。
由SONY A100到SONY A700，再升級到A850，係SONY已歷5年之久。說實話，SONY的確有很長足的進步，a850是一部備有A100的DR、A700的操控性，加上2460萬像素，以萬多元的價錢，同價格之相機只有APS-C才能與之相比。
此相機配合鏡皇及低ISO拍攝，有多恐佈真的要自已去感受一下(只能用囧來形容)
如此品質，乎復何求呢?

- 價錢低
- 像素高(2460 megapixel)
- 合金機身實淨
- 直倒好用
- 用電量低
- Viewfinder 清晰, 98% 基本與100% 無異
- 雙轉盤可方便同時控制光圈快門(5D2 只得一個, 用M mode 好煩)
- 相片色水好(Saturated)
- Mon 冇咁呃人 (C 記7D 未能反映out fo., 色水也較原本深和光)
- 黑位表現比C 記好, 也許C 記相片真的比較灰...
[以上優點對比C 記1D4 已經唔係優點, 但始終都貴成倍...但對比所以APS-C / FF, 都有較出色 / 相近的表現]

- 重[FF 中不算太重]
- 鏡頭少
- Noise Control 差 [後期更新後有大改善]
- 快門聲太大, 相比5D2 的確較嘈
- 快門太重, 易手震
- 連拍慢 [Full Frame 也不會要求連拍吧, 除了Nikon D3 系列外]

基本上呢部已經用咗年幾, 依然覺得好好用
原本用C 記APS-C, 因為對相片質素唔滿意, 就一跳上Full Frame
由於Sony 鏡只係信得過Zeiss, 但係Zeiss 又冇long range zoom lens, 50.4 同24-70 又唔夠人好, 只好入手平價Sigma APO 70-200mm EX DG HSM, Sigma 50.4 同27-70mm HSM f/2.8
一上手感覺實淨, 加上Sony 直倒依手形設計, 多攞都唔係問題, 以FF 機嚟講, 都唔算特別重(用過下5D2)
相片色水深, 還原度高, 對後期processing 幫助好大, 拍攝主體都比較立體(C 記相片顏色較灰, Nikon 則較油畫feel, 往往未夠立體)
但留意16GB CF 只能拍333張相 [Raw + Jepg]
其實...呢部真係一部性價比好高ge FF 機!

Full Frame單鏡反光相機

售價為FF機中最平

不是100%觀器
ISO得100-6400，去唔到12800
ISO800開始雜信明顯，或同大Senor 有關
每秒連拍得3張
無拍片 (但不重要)
易入塵

無悔

- Good focus speed although most of the people say it slow.
- Build in anti-shake
- Very accurate focus
- Bright and big OVF
- High quality photo when using low ISO speed
- High DR
- Weather seal
- Good control although its not fully Minolta style

- Noisy when ISO speed high then 800
- Focusing points are only cover the central area
- Shutter vibration quite strong
- lack of information in viewfinder and top LCD
- Processing speed will turn slow when turn DRO to auto or customise level

Great camera, I use it to take family and nature photo, good balance between on focusing speed and accuracy, I use it for 4 months now and very happy with and no regret to change my Canon system to Sony.

1) magnesium alloy body, solid built, robust and hefty
2) 24 megapixel all details recoded simply with a shutter.
3) Compatible with minolta lens, incomaprable c/p ratio~!
4) OVF big enough for shooters wearing glasses.
5) comparatively simpler control panel for novice shooters
6) Carl Zeiss lens with AF available

1) as an amatruer shooter like me, not-so-many gimmick functions say panoramic shooting, liveview, video shooting and 3d photo etc (not a weakspot if you are a serious photoshooter...
2) 3fps shooting
3) Poor iso control. over Iso 800 unusable even a33 is better in iso 800
4) accessories cost a bomb, particularly vertical battery grip
5) Not flamboiyant enough, gain lukewarm praise on the street :P

I bought A33 in October last year but it was too small to a 6 feet man weighing 100kg+. I also need a more balanced camera to hold my sigma 24-70 hsm. One day my colleague boast around with his A850 in the office and I was immediately intoxicated with its overwhelming pq and the gigantic OVF. After a little consideration, I decided to plead for my Queen's mercy and miracly my plea was answered. So that's how I got my A850. Longlive the Queen~!

You can't have your cake and eat it. A850 lacks most of the latest features available on apsc in exchange for a full frame cmos. It is of different league to apsc, what you should consider to upgrade your dslr is not just the specifications of the camera but your sincerity and determination to take good photos. If you are intended to boast around with it, it will be a lemon; but if you are intended to take good shots, it well worths the price.

可選F.F或APSC要加分、觀景器有目廉可關上、鏡头微調的功能及記錄

每秒得3張、對焦模組無提升還是9點追焦普通、無L/V及拍片雖然小用、希望sony加把勁直追C及N廠

2仟4佰萬像素抵用全片幅相機sony誠意之作由a700轉用全片幅後最大感覺是d鏡头好似獲得解放全部升呢、雖然觀景器得98%但比700大、全金屬機身手感好外形幾靚仔、幾頂無咗閃光燈有d唔慣次次都要帶外閃、之前用慣(直到)但850的直到比700大及重、都唔知買唔買好
