Canon EF 1.4X III Telephoto - Review

Canon EF 1.4X III Telephoto Extender for Canon Super Telephoto Lenses: An Honest Review

As a professional photographer, I always look for ways to expand and enhance my equipment. Having a telephoto extender can save me some money, time and space, as I don't have to carry multiple lenses, and Canon EF 1.4X III caught my attention. I researched and tested this extender and here's what I found.

First of all, let's talk about the construction quality. Canon is known for its superior build quality, and this extender is no exception. The extender is compact, measuring at 2.8 inches by 1.1 inches, and weighs only 7.9 ounces, which makes it easy to carry around. The lens construction consists of 7 elements in 3 groups and has a maximum aperture magnification of 1.4x. This makes it compatible with all Canon super telephoto lenses, hence extending their focal length by 1.4x. Even though the extender is small, it provides a significant increase in focal length, which is ideal for wildlife, sports, and other distant capture requirements.

One of the critical factors that I tested was the image quality, and I must say, I was impressed. The extender maintains the image quality of the original lens, which is great because image quality is paramount for professional photographs. Of course, at times you may notice some slight quality degradation and should factor that in while taking a shot.

Another aspect I found interesting is the autofocus functionality. The extender does affect autofocus speed, but not by a significant margin, and it's not very noticeable to the untrained eye. However, I would urge you to double-check the focus and sharpen your picture as needed, especially when photographing subjects that move very quickly.

Despite its benefits, the Canon EF 1.4X III Telephoto Extender has some limitations. Firstly, you'll need to use a tripod, as the extender does increase the weight of the camera and makes it a little challenging to handle. Secondly, you'll lose one stop of aperture when using it. For example, if your lens' maximum aperture is f/2.8, it will be reduced to f/4. But this is common in most telephoto extenders, and I believe it's a fair trade-off for the advantages that it provides.

Lastly, let's talk about the price. The Canon EF 1.4X III Telephoto Extender is a bit expensive compared to other extenders in the market, but I believe the extra cost is worth it, especially for professionals who require a quality extender that will last long.

In conclusion, the Canon EF 1.4X III Telephoto Extender for Canon Super Telephoto Lenses is an exceptional product that provides significant advantages for professional photographers. The build quality, image quality, and autofocus functionality are great. It's compact and easy to use, and the slight limitations it has are standard for telephoto extenders. I highly recommend it to any professional photographers who are looking for a telephoto extender that will produce quality images on any Canon super telephoto lenses.
