優點:
1)平 (price friendly)
2) sharp, even on subject at aperture 1.8
3) Not slow autofocus system. There are two conditions: 1. Update the lens firmware to 0.3. 2. The newer your camera, the faster the autofocus. There are a lot of posts about very slow autofocus system because the lens is using old firmware and the camera is old as well.
4)Closer min. focus distance than 55mm 1.8 za
5) Equivalent 75mm focal in APSC mode. A good form factor in full frame aMor APSC mode
缺點:
1) Noisy motor, may affect video performance
2) A bit over in high contrast 💁🏻♂️
3) It is very easy to have dirt and dust on the lens
4) Poor vignetting (can be solved with LRC)
5) Room for improvement on corner sharpness

A must buy lens for the price. Not much on the wish list for $1400. The disadvantages are not critical for this price point
