First, I wanna make an introduction about wide-angle lens, what is wide-angle lens? for I am not a person from an english speaking country, so I can't compose such professional sentences, the follow content was selected from wikipedia:
From a design perspective, a wide angle lens is one that projects a substantially larger image circle than would be typical for a standard design lens of the same focal length; this enables either large tilt & shift movements with a view camera, or lenses with wide fields of view.
As my personal mind, the above explantion was too verbose, to be short, wide-angle lens is a preofessional and hi-tech tool for you to catch more scenery.
Here, I wanna introduce the broadcast television wide-angle lens, like pro-photographers know, the famous brand of this lens include Canon, Fuji, they used for broadcast television, and like Zeiss, it used for film, it is more advanced and too expensive.
What I want say is not everybody have such money for those luxury lens, this is a truth, like Single-lens reflex camera, I have a joke on it, I always say: a person who take drugs will destroy his life, but a person who love photographing, his three generation will be poor person.
Of course, that is a joke, be seriously, there is a job in this society, named pro-photographers, they need work, they need equipment for photographing, they need consider their money when they decide to buy some equipments, so I have equipment for him to save their money, and keep good-working ability.
These are wide-angle adapters, in fact, they are not really wide-angle lens, they are just adapters, attached to the front of lens, like YJ20&KJ20,and the max wide converage is 70%, the advantage of this products are: same working ability with pro wide-angle lens, more cheaper than those famous brand, and they have name:chewa wide-angle adapters.
