[情報] Olympus vs Panasonic 25mm (Robin Wong)
來自43 rumors http://ppt.cc/6xFr
值得注意的是測試用機身是O家新機E-M10，也許用P家機身結果會不一樣？
結論：
1) The Olympus lens is slightly wider in field of view than
the Panasonic lens
同是25mm但Olympus視角大一點點？好像之前在其他鏡頭有過類似的討論。
2) The Olympus lens is *possibly 1/3 EV brighter than Panasonic
lens (not conclusive, based on just quick observation on EXIF data)
同樣參數下Olympus鏡頭的結果可能比較亮。
3) There is not much difference in shallow depth of field rendering
between F1.8 and F1.4 lenses (if point number 2 is true, the gap is
bridged due to either the Olympus lens being 1/3 EV brighter than
F1.8 or the Panasonic lens being 1/3 EV darker than F1.4. This is
just my observation, not a conclusive statement)
兩者光圈全開時的散景差異不大。
4) Although Olympus magnification factor is 0.12x and Panasonic
magnification factor is 0.11x, I find the close up shooting capability
of Olympus lens to be significantly better than the Panasonic lens.
O 25mm f/1.8實際放大率比P 25mm f/1.4大很多！
5) Panasonic lens has poorer CA control (especially shooting wide open) and
corner sharpness than Olympus lens.
這在O家機身上應該不意外...
6) General sharpness between both lenses are almost identical
期待在P家機身上的測試！
