Once you bought your first-ever DSLR camera, you have no choice but to learn everything about lenses. Why? It’s because lenses are the one that’s controlling the image that’s being projected onto the camera’s imaging sensor. Meaning, a good lens will guarantee you’ll get only the best image quality.

Lenses are commonly consisting of letters and numbers. If you’re new to photography, you’ll find those confusing and, honestly, a bit intimidating.

But don’t be! This article’s purpose is to avoid this kind of confusion and we’ll start that by discussing the lens’ aperture, focal length, format type and lens mount.

Best lenses for Canon 5D Mark IV

• Aperture

If you’re shopping for lenses for quite some time, you probably notice this: f/1.4 or F1.4-5.6. This is the lens aperture measurement. If you’ve seen one number (f/1.4), it means that’s the lens maximum aperture; while if there’s two (f/1.4-5.6), that’s the measurement range of the lens aperture.

Aperture has a measurement ranging from 1.4 up to 16. For some, they find this range confusing because they assume 16 has the largest aperture and 1.4 has the smallest. This is wrong! It’s actually the other way around, 1.4 has the largest while 16 has the smallest aperture.

So, if you’re planning to shoot in low-light condition without the need to use a flash, choose a lens with a larger aperture.

• Focal length

Focal length is the one that describes the lens’s angle of view and usually shown in a lens’ details in mm. If you’ve seen two numbers (20-300mm), it means that the lens can zoom to that range; while if there’s one number, it automatically means that it’s a prime lens.

This is an important detail to consider because a lens focal length can work differently depends on the camera’s sensor’s size (crop factor). The proper way to solve this is by following the 35-mm format wherein you’ll have to multiply the camera’s crop factor to the focal length of the lens.

For 5D Mark IV, it has a 1.74x crop. Multiply this by any lens’ focal length and the answer will be the equivalent field of view for that lens.

• Format type

Format type is the one that defines the sensor size that the lens is designed to work with. For 5D Mark IV, it has a CMOS sensor that’s also compatible with Dual Pixel CMOS AF.

• Lens mount

Determining the lens mount is the simplest way to determine the compatibility of the lens to your camera. For 5D Mark IV, it has a lens format of Canon EF mount only. If you’ve seen lenses with EF-S or EF-M on their name, it’s not compatible with 5D Mark IV.

The table below will show you the comparison of the 3 best lenses for Canon 5D Mark IV.

*Note: The format and lens mount of the 3 lenses are an exact match to 5D Mark IV.
