Hereof, What are zoom lens used for? A zoom lens is an SLR or DSLR lens that offers a different focal length for the photographer to select from.

How do I choose a fisheye lens? To achieve the “fisheye effect” you would need a lens with a focal length of between 8 or 10mm. Here’s a general guideline: If you’re shooting with a full frame camera like the Canon 5D Mark II or Nikon D700, you need a lens with a focal length of between 15 or 16mm.

What’s the difference between fisheye and wide-angle lens?
The difference is that a fisheye gives that pronounced outward bow from the center of the image, like you’re looking through a peephole in a door. Depending on the wide-angle lens you get, it too might have some of this “barrel distortion,” but it will be far less pronounced.
Which is better telephoto or zoom lens? For a beginner photographer, the zoom lens is better because a telephoto lens is expensive and also does not provide much versatility like a zoom lens. However, if you are a professional, then you definitely need a telephoto lens as must-have equipment.

Should I use zoom or prime lenses? If you are very particular about image quality and don’t need to adjust your focal lengths, then prime lenses are the way to go. But if being able to quickly take photos at different focal lengths is more important than having a small camera bag, then zoom lenses are the best option for you.
Why are fisheye lenses so expensive?
Manufacturers encounter a few problems when designing wide angle lenses. The lens typically holds more glass and ends up to be bigger and heavier than a standard lens. This drives the price of the lens up.
What focal length is fisheye? Usually, the fish eye lens has a very short focal length (less than 15mm for a 35mm-size image sensor), but a large field of view (FOV). The latter can be as large as 180-degrees, giving the user a complete view of a scene. This extreme FOV produces a characteristic image with a large distortion.
Is it worth buying a wide-angle lens?
Third, wide-angle lenses give a greater depth-of-field than telephoto lenses. In addition to using high aperture values, a wide-angle will ensure that the whole landscape is in sharp focus. These are three of the most important reasons why a wide-angle lens is well worth the cost for landscape photographers.

Is a fisheye lens concave or convex? Instead of producing straight line images (or rectilinear images), the fisheye lenses produce a characteristic convex image (non-rectilinear image) by using a special mapping angle (equisolid angle). An American physicist and inventor Robert Wood coined the term fish eye in 1906.
Can you put a fisheye lens on a film camera? Rokinon makes an 8mm fisheye lens for Nikon (F-mount, so it’ll fit film Nikon SLRs and DSLRs). Looks like it will work on 35mm film, as well as FX and DX DSLRs. It will mount on full frame, but it’s designed for crop and will vignette heavily on full frame (from the ephotozine review of the lens):
What happens when a fish eye lens is used for portraiture?

What lens do I need for long distance? If you need a camera lens for far away shots, you need a telephoto or superzoom lens. Telephoto lenses have a fixed focal length starting at around 70mm. Superzooms—as the name implies—are zoom lenses that cover a range of focal lengths. A popular second lens choice for many is a 55-200mm superzoom.
