To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Lens met my expectations in the three areas of: 1. Edge to edge sharpness, 2. Auto Focus speed, 3. Colour Saturation. I will be using lens with Z7 now for my adventure travel and trekking as it has excellent sharpness across the frame for landscape images.
