Whichever lens is chosen, photographers can be pretty sure that a prime macro lens will be a great lens. There are also lenses that extend the normal focal lengths available and 180mm or 200mm macro lenses also have a following, at a very high price.

MFT format lenses would be the 25mm instead of a 50mm, or the 50mm instead of a 100mm.įinally, there are macro lenses that offer images of greater-than-life-size reproduction, perhaps going to 2:1, where a 1cm long subject would be 2cm long on the film or sensor. The actual focal lengths on offer will show some variation around these figures. Rather than a 100mm, perhaps the 50mm or, where available, the 60mm. If we relate this to APS-C sensors, then the focal lengths vary accordingly and rather than a 50mm, a 35mm macro might be more suitable. There are exceptions of course, and for document copying the 50mm might be a better choice in that it allows for less height using a tripod-mounted camera, and hence an easier view of the camera monitor. That is because it enables 1:1 magnification at twice the distance compared to a 50mm, thus not crowding wildlife subjects and allowing space for lighting.

Shake reduction/vibration reduction/image stabilisation may or may not serve well, and lenses may provide instructions that are specific.Īs regards focal length, if we consider full frame sensors, then the most popular is probably the 100mm.

AF itself may not be accurate or convenient, and some shots will be better served by using manual focus. There are some modern features on cameras and lenses that may not always be the best option for very close macro work. Another major requirement is low distortion, so that straight lines, especially at the edges of an image, remain straight lines. For example, to copy documents it is no good if a lens is sharp in the centre but fuzzy at the edges because the image projected is not flat but curved. It is also important that the image should be in focus all across the frame, in other words, have a flat field. Obviously high quality even at close distances needs to be maintained. There are other properties that are desirable in a macro lens. Zoom lenses can often focus very close, and may be referred to as macro, but usually only offer magnifications of around 1:4, or 0.25x, also known as one-quarter life size. For those buying older lenses, the norm used to be a magnification of 1:2, or 0.5x, also known as half-life size. This means that the lens must focus very close and most current true macro lenses will indeed produce images at a 1:1 magnification. This simply means that a subject 1cm long would be 1cm long on the film or sensor. Macro means a lens that can reproduce a subject at a magnification of 1:1, or 1x, also known as life-size. There are technical terms that define what macro means and although the description is precise its application to lens names and descriptions can be slightly more flexible. Among our large review collection is a rather long list of lenses which are designed to capture excellent macro images and close-up photos. Macro lenses are great for detailed close-up shots, product photography, insect photography and more, but can also be used as a portrait lens. Here at ePHOTOzine, we have reviewed hundreds of interchangeable lenses in our time so when you guys are out shopping for a new lens, you have as much information as possible for making your decisions. If you're looking for the best macro lens, then you've come to the right place.
