If you’re a photographer, you know the importance of having the right gear for the job. And one of the most important pieces of equipment you can have in your arsenal is a good telephoto lens. The Canon 100-400mm lens is a popular choice for many photographers, but sometimes you need a little extra reach. That’s where an extender comes in. In this article, we’ll take a look at some of the best extenders for the Canon 100-400mm lens in 2023.
What is an extender?
An extender, also known as a teleconverter, is a device that attaches to the end of your lens to increase its focal length. This effectively makes your lens longer and allows you to get closer to your subject without physically moving closer. For example, a 1.4x extender will turn your 100-400mm lens into a 140-560mm lens.
Types of extenders
There are two main types of extenders: those made by the camera manufacturer and those made by third-party manufacturers. Canon makes its own extenders, such as the Canon Extender EF 1.4x III and the Canon Extender EF 2x III. Third-party manufacturers, such as Tamron and Sigma, also make extenders that are compatible with Canon lenses.
Canon Extender EF 1.4x III
The Canon Extender EF 1.4x III is a popular choice for many photographers. It increases the focal length of your lens by 1.4x and maintains autofocus and image stabilization. It’s also weather-sealed, so you can use it in harsh conditions without worrying about damage to your equipment.
Canon Extender EF 2x III
If you need even more reach, the Canon Extender EF 2x III is the way to go. It doubles the focal length of your lens, turning your 100-400mm lens into a 200-800mm lens. However, because it doubles the focal length, it also reduces the amount of light that gets to your sensor. This means you’ll need to use a slower shutter speed or higher ISO to compensate.
Tamron SP 1.4x Teleconverter
If you’re looking for a third-party extender, the Tamron SP 1.4x Teleconverter is a good option. It’s compatible with Canon lenses and increases the focal length by 1.4x. It also has a moisture-resistant construction, making it ideal for use in wet conditions.
Sigma Teleconverter TC-1401
Another third-party option is the Sigma Teleconverter TC-1401. It’s compatible with Canon lenses and increases the focal length by 1.4x. It’s also designed to minimize chromatic aberration and maintain sharpness and contrast.
How to choose the right extender
When choosing an extender for your Canon 100-400mm lens, there are a few things to consider. First, think about your needs. Do you need more reach? Do you need autofocus and image stabilization? Do you need weather-sealing? These factors will help you determine which extender is right for you.
Pros and cons of using an extender
Using an extender has its pros and cons. On the one hand, it gives you more reach without having to buy a longer lens. It’s also more affordable than buying a new lens. On the other hand, it reduces the amount of light that gets to your sensor, which can affect your image quality. It can also slow down your autofocus and make your lens less sharp.
Tips for using an extender
If you decide to use an extender with your Canon 100-400mm lens, here are a few tips to keep in mind: – Use a tripod or monopod to keep your camera steady. – Use a higher ISO or slower shutter speed to compensate for the reduced light. – Use manual focus if autofocus is too slow. – Avoid using the extender with the lens wide open. – Be aware that image quality may be slightly reduced.
An extender can be a great way to extend the reach of your Canon 100-400mm lens without having to buy a longer lens. Whether you choose a Canon extender or a third-party option, make sure to choose one that meets your needs and fits your budget. With the right extender and some practice, you can take your photography game to the next level in 2023.
