優點:
- initial using in 7D, cropping with very little distortion, much better than similar of Sigma.
- very sharp resolution and color
- very good climate usage, especially in rainy
缺點:
Distortion in 5D3, but it is normal, 17mm is closing to fish eye.
評價:
I like it so much. I will take it as standard lens and carry a 2nd lens with 50mm or 100mm, depending on place and season.
