I consider that the user's inability to select the appropriate lens to use. This and coupled with lack of planning and taking photos to hastily and not so much of a problematic lens. Just like people complaing about the perspective distortion UWAs render and saying some lens are better controlled than the others. Its really about the lack of understanding of the lens since perspective distortion is focal length dependent rather than lens design. As with all other lenses, it takes time to master.
Perhaps with the exception of the 14mm, the 14-24 covers focal lengths which are used by many photographers, for many years, in countless situations, covering a vast number of genres. Its hardly a specialised lens. Misunderstood...always but definitely not specialised. Its not like a perspective control lens or a macro lens with magnification which performs other functions. Most probably, those people sold their UWAs way before they even start learning how to use these lenses.
I fully agree. Eloquently put. :thumbsup:
