Working distance: The difference between the tip of the lens and the subject.Īlso see: What Does “Closest Focusing Distance” Refer To? Longer focal lengths usually involve a longer closer focusing distance. Recap: Closest focusing distance and working distanceĬlosest focusing distance: The shortest distance that must be placed between the image sensor and the plane of focus on the subject for the lens to be able to focus. This is because the lenses have different closest focusing distances, also known as minimum shooting distance. You probably know that intuitively -after all, subjects get bigger in the frame when you move closer to them or zoom in!īut if that’s the case, why do super telephoto lenses have smaller maximum magnifications than shorter lenses? For example, the maximum magnification of the popular RF100mm f/2.8L Macro IS USM is 1.4x, but that of the RF600mm f/4L IS USM is just 0.15x. How much a subject is magnified on the image sensor depends on factors like the focal length and shooting distance. Maximum magnification, closest focusing distance, and focal length: How are they related? The relationship between maximum magnification, closest focusing distance, and focal length

However, it must be capable of at least life-size magnification for it to be considered a true macro lens.ĮOS R5 + RF100mm f/2.8mm f/5.6, 1/100 sec, ISO 160Īt 1.4x magnification on the RF100mm f/2.8mm, the vein structure of this leaf is shown in amazing detail. The maximum magnification is an important specification for macro photography, as it determines how much of the frame you can fill with a tiny subject.Ī lens is usually considered a macro lens if its maximum magnification ratio is at least 0.5x (or 1:2). But for the sake of convenience, let’s imagine that it’s 1cm across.) (In real life, a ladybug is much smaller. We say that this lens is capable of life-size magnification.Īs the animated image below shows, anything below 1.0x magnification is actually a form of “reduction”: the image projected on the image sensor is smaller than the actual object. When a lens has a maximum magnification ratio of 1:1 or 1.0x, it projects onto the image sensor an image of the object that is the same size as the object in real life. It can be written as a decimal (for example, “0.5x”) or as a ratio (for example, “1:2”), but the numbers refer to the same thing: the ratio of the size of an object as projected onto the image plane (i.e., the camera’s image sensor) versus the size of the object in the real world. In photography, “magnification” is usually used to refer to the magnification ratio or reproduction ratio of a lens. To get tack sharp bug eyes at 5x, I’ve had the best results at f / 9.What is “magnification” in photography? What is “magnification” in photography? If you were to use f / 16 at 5x, due to physics and the way light bends, your subject would appear blurry when you zoom in. 1x – f / 16 or f / 14 (I prefer f / 14 to make my background card look blurry).I change the aperture based on how zoomed in I am with the MP-E.My starting settings are: +1 flash compensation, ISO 100, F / 14, 1/200th shutter.I tape one paper towel over each flash head to make a little fluffy ball to soften the light.I use the stock diffusers that come with the flash.I have a very simple diffuser on the MT-26EX twin flash.In the video, I use my custom macro backgrounds since I enjoy adding some extra color to photos.

I really love the MP-E lens since it lets me get very close to bugs and at 5x I can usually fill the frame with a bug’s head! I lucked out and had a bug waiting for me right by my door, so I picked him up, gave him some water, and made a video tutorial showing how I use the Canon 65mm MP-E 1x-5x macro lens with the MT-26EX twin flash on the 5D Mark IV.
