What kinds of lenses does the camera have? What is an eyepiece? What is an eyepiece? To be more specific, don't copy if you have experience.

Your problem is too big. Let me try to answer.

Camera lenses can be divided into two categories: 1. Fixed focus lens; 2. Zoom lens.

Fixed focus is divided into: 1. /kloc-fisheye glasses under 0/8mm; Super wide angle of 2.20mm; ; 3. Wide angle 24-28 mm; 4. Standard 50mm；; 5。 Medium coke105-135mm; 6. The telephoto is more than 200mm.

Scaling is divided into: 1. Wide-angle zoom18-35; 2. Standard zoom 24- 105 3. Medium zoom 55-200 4. Long zoom 100-400.

Eyepiece is not included in the classification of photographic lens, but the lens that the camera sees with its eyes. In some special occasions, it is not convenient to look directly at the eyepiece. An external eyepiece, such as a 90-degree right-angle or straight eyepiece, can be added to the eyepiece.

I wonder if this answer will help you.
