Super Zoom Binoculars

Why doesnt lens camera makers make bigger diameter lenses?

I've been reading about telescopes and binoculars, and they say the bigger the diameter of the lens the sharper & brighter the image. Ex. an 8x80mm binoculars produce brighter and sharper images than an 8x20mm, though they have the same zoom power. Why doesn't Canon make a giant diameter lens to create super sharp photos?.. I've been using a dslr 12megapixel, but that much pixels is useless if you have a blurred image. Yeah thats how I put it: High-res blurred images.
I find non zoom lens make sharper images though.

Prime lenses ("non zoom lens") are capable of doing sharper images than a normal zoom (in the right hands) due to the higher quality components.

My 70-200 f/2.8L is bigger in diameter than the 75-300 f/3.5-5.6 (and weighs almost 3 times more) and produces sharper images but it comes at a hefty price (7 times more expensive).

There are "giant diameter" lenses...look at the Sigma 200-500 f/2.8...it is huge!!! BUT who wants to lug a 33 (thirty three) pound lens around all day?!?!?!?!?!?

Photography is more about photographer skill than equipment size. I have seen better photographs from a professional with a cheap camera (including a homemade pinhole camera), then I have with an amateur using an expensive camera.

If you are producing blurred photos, I would check the photographer first, and not blame the lens.
