Good:
- Brightness
- The speed of the AF
- The stabilizer
- The correct stake in well
- The accuracy of the ring
Not good:
- The slight vignetting at f2.8 17mm and 50mm accentuated
- The noise of the stabilizer
- The hardness of the ring (but offers accuracy as mentioned above)
- Weight (but it is an inevitable consequence)
In very happy conclusion of the purchase, because all the negative points are not rédibitoires. This objective is quality "semi-professional".
PS: Delivery via DHL by Amazon did not give me complete satisfaction in terms of delays. (Shipped on 12, reception 21)
