大家好ar!!
首先講明先,我出lee個topic係真係有心去探討兩部機o既photo quality, 而唔係想作出任何惡作劇o既post!!^^

因為我兩部機都有玩過(7hi and A1), 但係我真係覺得好奇怪ar!!
第一, 首先講一講係日光充足o既情況下影o既相先!! 我真係覺得7hi係noise o既控制上面真係好過A1 ar, 我覺得A1 o既noise真係多過7HI, 但係A1o既noise control唔係話好過7hi ga咩?!?! 我已經有開NR ga la, 同埋唔開anti-shake, 但係noise都係多過7hi, 其實都冇乜特別o既暗位ga la, 但係唔知點解都係會有noise, 唔知有冇朋友同我一樣都玩過晒兩部機呢!? 同埋有冇lee個感覺呢!?

跟著就想講一講夜影lu!
我諗好多朋友都知道A1 o既長時間o既exposure下有好多o既noise, 同埋滿天星斗(註: 我已開了nr)
但係有用過7hi o既朋友, 我相信佢地都會好滿意7hi係long time exposure下o既表現ar!! 由其是用blub多過1秒o既情況下, 因為多過1秒有nr, 可以話極少noise, 我就覺得好perfect ar!
我有兩張相比大家參考下:

A1 30秒exposure, 有開nr

7hi 30秒exposure, 用blub, 有nr

好la, 咁我諗著long exposure唔係A1 o既強項, 我試一試用大光圈+0.8s la, 但係我都係覺得真係好多noise ar!!!

因為小弟部A1係問朋友仔借左黎玩一牌ar, 本身自己都想upgrade 部7hi去A1 ar, 所以我都想清楚知道, 係我自己心理作用ar? 定係only我朋友部A1先會有咁o既問題, 還是大家o既諗法都係同我一樣呢?
真係好鍾意a1 o既function ar! 如果only係我個friend 部機o既問題就好lu!!! hehe^^

真係冇師兄表達下意見ar?!
我都想聽多d大家o既意見ar, 可以分享下ma?^^

NR 係o係 1s 之後才會使用的

7Hi 比 A1 少 noise, 好像聽聞過

看過不少 A1 的白天作品, 白天都有這麼明顯的 noise 無可否認了說

不過 A2 就真的有明顯改善

SiuSiuMing兄
現時A1同A2行貨價相差唔過$2000, 但A2係好多細微地方, 如evf, noise控制等作出改善, 雖然好多人話800萬像機多noise, 但我用落完全唔覺, 一般黎講影夜景用b門多數都係儲存成raw, noise會低過jpeg好多同可以用軟件後期加工去noise, 功能同畫面上A2好過A1好多. 勸你放棄A1, 貴少少買部A2, 因為真係有明顯改進同可以用耐D^^
我相信你都聽過A2有QC問題, 如果你怕有問題可以去永成買, 我係永成買, 用左兩部機都完全冇發現傳聞中既QC問題同輕機等, 相信永成入既呢批貨係冇問題! $7380送256MB, 比現金仲有其它野送(我就送左個相機袋同LCD保護膜) 至於鐳射, 我上次問價時現金$7050, 送256

SiuSiuMing, I got an A1. If you are worry about the "noise" issue of A1, or you would like to take a lot of night shot, forgot about it. The A1 30s night shot sample in your post is very normal, it happens even in 10s.

Of course, A1 does have its own advantages over 7hi (thatz why u want to upgrade), just see if u can accpet the noise issue :)=

多謝Richard1989同埋robot17兄o既建議同埋回覆ar!!!^^
robot17兄ar, 我有d野想問ar!! 我都明白如果一長時間exposure, 我一定要接受得到a1會有好多noise!!
但係robot17兄有係日間影o既時候, 覺得noise level如何呢? 同埋夜晚如果係1秒之內開nr, noise level又何否接受呢? ^^

[robot17]

SiuSiuMing, NR is only applied on explosures of one seconds or longer. A1 performs better for night shot within 1 second explosure, probably u will only see a few hot spots in dark areas of the picture.

For noise in day shoting, I don't want to give subjective comment and actually I don't have enough knowledge in answering this question (I have no reference to tell what is the "acceptable" noise level).

I also have a W-1, for noise control, it performs obviously better than A1. U may see the A1 photos in fotop or pbase and make a judgement by yourself.

Enjoy!

各位,....其實我本來打算買A1的...($4650)
因為我的buget 真的唔多...

但聽完各位意見之後....又好似買A2好些...
但A2我只夠錢買水貨....($6000)

請問如果買水貨A2 是一個大問題嗎?
好像聽說A2有很多的QC問題..

如果不能買A2行貨..
還是買A1好些嗎??

[fongbiu]

首先請問SiuSiuMing兄有關你兩張相的拍攝情況,A1及7 HI兩張分別係開機

後多久才拍的. A1那張的熱點明顯較多,那不是noise這麼簡單,

7 HI 那張noise control亦係真的好過A1 那張,不過要有開機時間數據及

拍攝時的溫度作分析,但點都好7 HI 那張好D,(A1 那張鏡頭有塵)

to fexx 唔怕老實講如買A2 水貨請小心試清楚才買,亦請於可換貨其間多拍

多試,如果真係要返廠三四次就條數就係返度,可能重要比凸添,

如果暫時不能買A2行貨,還是待有足夠銀兩才買A2回家勝於買A1

此乃個人見解,如有異見,請諒.

[robot17]

SiuSiuMing, If you have tight budget, u may consider to buy water A1 first. Then you can also buy other accessories such as:
- NP400 battery grip (highly recommend, make it more balance and looks better :)
- Extra battery
- UV filter
These stuff costs you ~$1200.

小弟今日最後都買左部a1 la!!!!!!!!!!!
only take過一d日頭影o既相做test, 一番到屋企即刻走去睇睇la, 發覺d noise都唔係太多ja wo, 我原全可以接受bor, 同我個friend果部差好遠wo!!! 因為我之前都借左我個friend果一部玩左成個星期ar!! 真係唔知點解會咁, 唔通真係部部機都會有d分別, or only我friend部機o既qc有問題?!?!
等我今晚試埋night shot先!!

To: fongbiu兄
其實我以上所提供o既兩張相係www.dpreview搵出黎o既, 係sample pic ar!! 所以真係冇法知道係開左機幾耐之後take o既!!
不過我都相信以上o既兩張相都持平ga la!! 因為我都試過用部a1 用8s take過一張(一開機就take ga la), 都有成203點hotpixels!!
不過hotpixels我都真係唔會太介意, 因為hotpixels好容易用software執得到ma!!^^

To: robot17兄,
thx for ur kindly recoomend ar!!
I really decide to buy the hand grip BP400, second hand is more prefer ar!! hehe!!
buy the 3600HSD flash also, it's really important to take the protrait shot!!

[waterng]

其實~有幾何用100%(1:1)咁睇相丫~
所以好似我呢D咁既普通用家~A1己經好好la~
如果去晒相~我個人就好喜歡佢D相好有菲林沖晒既味道~
Happy shoting~小小明
