Lenses buying guides
Lenses shape your photos more than most people expect. First, make sure the lens fits your camera's mount, the ring where it attaches. Focal length, shown in millimeters, tells you how wide or close the view is. A lower aperture number, like f/1.8, lets in more light, so dim rooms look cleaner. Bigger lenses cost more and weigh more, so match them to how you shoot.
We haven't published a Lenses guide yet. We only publish a guide once the research behind it is done.
