Can the big three elements be mounted on the lens together? Or can you only install one at a time? Canon or Connie?

A camera can only be equipped with one lens. The Big Three refers to Canon's three top zoom heads, which cannot be installed on the same camera at one time. Specifically, whether Canon or Nikon is better, this has always been controversial in the photography circle. Everyone has their own opinions. Personally, I think Canon is better. Because I am a business owner, Canon is more convenient than Nikon when it comes to taking portraits. This saves us a lot of effort.

Canon and Nikon each have their own lenses. The focal length is the same.

Canon's three-dimensional lenses are 16-35 2.8 24-70 2.8 70-200 2.8 is. Canon's three-dimensional lenses have a constant aperture of 2.8, with a red circle in front of the lens. To differentiate, in terms of telephoto range, the difference between Canon and Nikon is that Canon uses white engineering plastic for its 70-200 lens. We can all see this lens on the edge of sports venues, and friends like to call them " Cannon”, with a red circle, of course. Canon also has three small lenses, namely 17-40, 24-105, and 70-200. The apertures are all constant F4.

Nikon uses a gold ring and Canon uses a red ring.
