Most: - Fabulous dive - Correct weight - Bright enough for its use (in the landscape is rather firm diaph to enlarge the PDC so it's all good) - AF silent and very fast. Cons: - High price - No stabilization (but in perspective given the range) - A bit of distortion 18 mm (easy to fix JPEG draw or live box if you enable the option for JPEG) - Bulky enough - No processing Nano but at this price, it must not ask for the moon ... CONCLUSION: After 3 months of use, I'm delighted, it makes an excellent team with my D610 and my 28-300. highly recommended.
