A convex lens is curved outward on both sides. Also, a convex lens, is used to enlarge objects.

Concave lenses work by refraction of light.
with the help of convex lens we are able to converge the beam of rays to the fix point.
For a convex lens the focal point is the transition point between getting a real image and a virtual image. If the object is at a greater distance then F you get a real image. If the object is closer to the lens then F you get a virtual image. If the object is located at F the light rays from the object leave the lens parallel and never form any kind of image.
The lens on these glasses are clear in low light then transition (or change) to tinted glass in bright light.
Photochromatic lenses are commonly called transition lenses. The lens is clear, but when exposed to the sun's UV rays, they will darken like sunglasses.
zoom
It depends if the camcorder has the physical settings to attach the lens.
Yes. If the lens is a EF or EF-S lens, it should work fine with the t1i
What some people call Transitions, a registered trademark, lens are designed and built to react to light levels. Low light the lens stay transparent, when bright light hits the lens the way the lens are made makes the lens change to the apropriate level of dark in a fraction of a second.

NO. The lens is required to focus the image on the CCD sensor.

Each concave lens bends light to make the object appear larger
