銳利度:中央微勝，邊角大勝O45
兩鏡不論接P機O機，對焦速度都是P42.5較快 / P42.5在GX7上快於在E-M1上
星芒醜，慘輸O45
防手震補償測起來只有三級
Summary
Good points
Sharp across the frame even at maximum aperture.
Close focusing distance allows respectable macros.
Very compact and light body. Lens hood supplied.
Optical stabilization reduces wobbles on Lumix bodies.
Bad points
Stabilisation provided modest compensation in my tests.
Starburst diffraction not as defined as Olympus 45mm.
Some fringing with bright point sources on Olympus bodies.
Many MFT owners will already have Olympus 45mm.
