What Size Lens Cap For Canon 85mm?
A Comprehensive Guide for Beginners
Introduction
The Canon 85mm lens is a popular choice for portrait photographers, with its fast aperture and flattering focal length. But what size lens cap do you need for this lens?
The answer depends on which version of the Canon 85mm lens you have. The EF 85mm f/1.2L II USM and EF 85mm f/1.4L IS USM lenses require a 77mm lens cap, while the EF 85mm f/1.8 USM lens requires a 58mm lens cap.
It's important to get the correct size lens cap for your lens, as too small of a lens cap won't fit properly and could fall off, while too large of a lens cap won't be able to snap on at all.
How to Find the Right Size Lens Cap
There are a few ways to find the right size lens cap for your lens:
- Check the lens manual: The lens manual will usually list the size of the lens cap required.
- Measure the lens filter thread diameter: The lens filter thread diameter is the size of the filter threads on the front of the lens. You can measure the lens filter thread diameter with a ruler or caliper.
- Look at the lens cap: The lens cap will usually have the size marked on it.
Why is it Important to Use a Lens Cap?
Lens caps are important for protecting your lens from dust, dirt, and scratches. When you're not using your lens, it's important to put the lens cap on to keep it safe.
Lens caps can also help to protect your lens from the sun's UV rays. UV rays can damage the lens elements over time, so it's important to protect your lens from them.
Types of Lens Caps
There are two main types of lens caps: front lens caps and rear lens caps.
Front lens caps are used to protect the front element of the lens. Rear lens caps are used to protect the rear element of the lens.
Front lens caps are typically snap-on caps, while rear lens caps are typically screw-on caps.
How to Use a Lens Cap
To use a lens cap, simply snap it on or screw it on to the front or rear of the lens.
When you're ready to use the lens, take the lens cap off and put it in a safe place.
