The degree to which your subject is out of focus depends on your aperture and relative distance. The subjects or areas outside of it are your depth-of-field. The subjects in the plane will be in focus. When you change the angle or position of your camera, the plane of focus remains relative to your sensor. It represents the theoretical plane of sharpest focus and lies in the depth-of-field. The plane of focus is a two-dimensional imaginary plane that lies parallel to your camera’s sensor. It’s important to understand the concept of plane of focus and how it affects depth-of-field. This means that I need to be at least 1.02′ (31 cm) away from my subject to get proper focus. for example, my Canon 100mm f/2 macro lens has a minimum focusing distance of 1.02′ (31 cm). The longer your focal length, the farther away you need to be in order to focus on your subject. The minimum focus distance of a lens determines how close you can get to your subject and still focus to achieve sharp images. You don’t get that much tighter crop as you do when shooting with a cropped sensor. When you shoot on a full frame, the focal length is as stated. For example, you get a focal length of about 80mm when shooting with a 60mm macro lens on a Canon Rebel, which had a crop factor of 1.6. If you’re shooting with a camera that has a cropped sensor, your macro lens will behave differently than it will on a camera with a full-frame sensor. The focal length of your lens and your camera type will affect your results. In effect, a macro lens is like having two lenses in one. In this case, you’re actually are not using the macro capabilities of the lens. You can also move back from your subject and take beautiful food portraits, without the distortion some other lenses might give, especially when shooting at a 45-degree angle. However, you don’t just have to take close up shots with a macro lens. This means that the ratio of the subject on the size of the sensor plane is as large–or larger–than your subject. In food photography, you can highlight the textural and colour detail that often go unnoticed or underappreciated.Ī true macro lens has a magnification ratio of 1:1 or greater, and a focusing distance of around 30cm. It allows you to take sharp photos of very small subjects or capture fine detail. In fact, if I could only have one lens in my kit, it would be my Canon 100mm macro lens.Ī macro lens gives you the ability to shoot with short focusing distances. Why a Macro Lens is Your FriendĪs a food and still life photographer, my macro lens is my best friend. This means optimizing the way you handle focus for your food subjects. To make beautiful food images with your macro lens, you need to get your subjects in razor-sharp focus. Macro photography is stunning but it comes with a unique set of challenges.
