有無R4用t鏡100% crop睇下有幾差
2021-05-06 00:38:28
我已經放晒,冇貨 不過肯定比唔到GM果隻「嘩」一聲嘅sharpness
2021-05-06 00:44:10
咁如果 Sony 35 1.8 同 sigma 35 2 比呢?
主要用嚟街拍

頭先上面有條片比較新嗰支F1.4 同 Sony 1.8
好似Sony嗰支質素仲好啲
2021-05-06 00:48:46
For 街拍我簡s35 f2
有光圈環方便好多
2021-05-06 00:54:35
SAMYANG新24 1.8竟然咁低
2021-05-06 01:21:27
膠攝好似話 Sigma 支f2好過支hsm art

對焦 光圈 近攝 Sony f1.8 > Sigma f2

少紫邊 色散 flare Sigma f2 > Sony f1.8

利申: 都係街拍 當年買個時考慮對焦入咗Sony f1.8

2021-05-06 13:50:49

原作者係用a7r4去試

Outstanding
At this grade you exploit the full potential of the 61Mpix sensor
Everything is tack sharp even on a 100% Crop with excellent contrast
Very few lenses will achieve this grade on the entire frame
Excellent
At this grade you reach excellent results , it is only by comparing to an outstanding lens that you can see that you can do a little bit better
This is the grade that will exploit the full potential of 42Mpix of the Sony A7RIII
Lenses at the grade are perfectly OK on the Sony A7RIV
Very Good
At this grade you still get very good result but expect the start of some softness when viewing a 100% crop of 61Mpix
This is the grade that will exploit the full potential of 24Mpix of the Sony A7III
Lenses at that grade are not enough to exploit the A7RIV at any aperture but still give good results if you don’t crop heavily in the pictures
Typically some Excellent prime will fall in this category when used Wide open
Good
At this grade the image is still good when viewed globally but lack sharpness when viewed at 100%
Those lenses are still recommended for A7III but are not recommended on the A7RIII
Those lenses are not adequate for A7RIV
Average
Those lenses can barely achieve very good results when aperture is closed down and in general they are not even on the entire frame
Those lenses are not adequate for A7RIII, A7RIV
Those lenses are acceptable on a A7III but do not exploit the potential of the 24Mpix
Bad
Those give bad results when viewed at 100% on the all bodies (A7III, A7RIII, A7RIV)
Only Ok for TV viewing , computer if not zoom in

係囉都excellent
想知係咪真係食唔到R4
2021-05-06 17:52:25
Outstanding
充分發揮61MP A7R4
100% crop in都好正
得好少鏡做到

Excellent
已經好正, 唔對比Outstanding鏡, 都好難睇到有分別
充分發揮42MP A7R3
A7R4用都perfectly OK

Very Good
61MP用都very good, 但100%crop會開始有d soft
可以充分發揮24MP A73
呢級數鏡頭用任何光圈都發揮唔曬A7R4, 但唔Crop到好勁都唔錯嘅
大多數Excellent prime光圈全開都會跌到呢級

Good
成張睇都仍然good嘅, 係sharpness差小小
A73用都ok, 但唔建議A7R3用
A7R4完全唔建議用

Average
收光圈先叫做Good
A7R3 A7R4完全唔建議用
A73可接受, 但唔能夠充分發揮

Bad
100%睇都唔掂

t70180 係高分過70200囉
2021-05-06 17:59:52
唔知點解好多人話70200好過70180
到底有冇真係拎上手
同一情況係影黎試下對比
定係自己用緊70180就係到吹好好呢

利申2枝都冇
2021-05-06 18:00:19
原作者用r4試
2021-05-06 18:02:47
70200上showroom拎完上手即刻唔想買
因為太重

不過一支有防震一支無喎
同埋支70180好膠
我最後揀左70180

R3真係無投訴
2021-05-06 18:13:02
睇表係t70180>70200
返去再睇佢點試先
佢有講大部份鏡 F5.6~8係最sharp
佢個評分主要係睇呢個光圈
