I guess from another perspective, a product when launched , is bound to draw comparisions from its competitors. I guess , we all like to make references and identify differences.
When a product is launched and the masses didnt like it, there will be collective criticisms of the products. To turn around and say that those people making such comments arent the targeted audience is not a very strong argument on its own.
So if we were to throw the question to Nikon marketing and ask, who are your target audience ? I dont think the answer will be "niche market".
I guess what people is saying is , as a new entrant into the mirrorless segment, that is roughly 3 year old, the product has minimal differentiating factors to woo the potential buyers in this segment.
Who are the buyers in the segment ? Unfortunately, I think most of them will not be the pros. Alot of will be consumer will are looking for a affordable , high IQ , stylish camera, that is easy to use and yields better results than pns.
