VY Optics manufacture kinds of camera conversion lenses,include wide angle lens,telephoto lens,fisheye lens,adatper ring,lens cap,lens hood,lens cover,star filter, adapter tube,custom lens,OEM,projector lens.All conversion lenses are fit for Canon and so on.Beside,we supply OEM service.
Telephoto lens has a narrower angle of view,it thus gives apparent magnification to objects,it also seems to compress distant things, and there is less depth of field. The most obvious is to allow photographs of distant organisms to be made.
Fisheye lens distorts straight lines into ridiculous curves. Straight lines, depending on where they are in the photo can be pulled a lot, a little, or not at all. The farther they are from the the center line of the photo, the more distortion there is. The closer the line is to the midpoint of the X or Y axis of the lens, the straighter the line will be.
Perfect lenses,fast delivery,best service,small order available,OEM service and design as expected will be your first choice.
