A 35mm lens needs a very small minimum focus distance of just a few inches in order to achieve a macro ratio of A mm lens, however, can achieve that ratio from a few feet away, thanks to the zooming power of the lens.
Macro lenses are available in several different focal lengths. Which one is the best? That depends a bit on what you are shooting. Wide angle lenses of course capture a wider perspective. But for other subjects, a wide angle macro lens can work well. Telephoto lenses cut out more of the background. Telephotos, however, are often a bit pricier than their wide angle counterparts.
Most macro lenses focus up close, but can also focus to infinity like a normal lens, so you can use them for other types of photography too. Like other lenses, macro lenses are either fixed focal lengths i. The benefits of a zoom lens are easy to see. They can cover a range of focal points, so you want have to switch lenses.
However, zoom lenses are expensive. Fixed lenses are generally inexpensive, making them more accessible for hobbyist photographers.
Fixed or prime lenses also tend to have wider maximum apertures. The maximum aperture you can use is determined by the lens. The distance between the camera and the subject plays a role too. Deciding which focal length will work best for your needs is, as usual, part of the lens selection process. Longer focal length macro lenses will give you more working distance at - this reduces the tendency of live subjects to fly or crawl away. Longer focal length lenses also have narrower angles of view, which means that there is less background to incorporate into an attractive-looking image.
And that background will be more-diffusely blurred, as shown below. As a rule, the same framing and the same aperture results in the same Depth of Field DOF until focus distances approach the hyper-focal distance. But, perspective, compression, and angle of view are very different between these sample photos. The mm lens shows only a small physical area of the subject's background that is enlarged, magnifying the blur.
Background elements in the 60mm picture appear to be more in focus. However, they just about as blurred though these elements are far less magnified. There are also more background elements showing because of the 60mm angle of view. The result is a less diffusely-blurred background. If you are using a backdrop such as rolled paper , the background blur aspect will not likely be important to you.
There are downsides to the longer focal length macro lenses, including larger size, heavier weight, and faster shutter speeds required for handholding. Longer focal length macro lenses typically cost more than the shorter counterparts.
I tend to prefer longer focal length macro lens result best, but find myself using the aboutmm focal length the most. It is essential to understand that the depth of field at macro focusing distances is very shallow. Here is an aperture comparison as illustrated by a mm lens:. While I had occasional issues with chromatic aberration, the sharpness, bokeh quality, and price more than made up for it.
Longer macro lenses tend to have astonishingly good image quality — for a generally hefty price. These lenses also offer the best working distance of the bunch, which is often essential for insect photography. Another advantage of the longer working distance is the ability to use a creative macro technique: shooting through out of focus flowers. Yet these lenses are quite heavy, which makes hand-holding for long periods difficult , and doing so in low light nearly impossible.
The long macro lenses include the less expensive Sigma mm non-OS , which is a bit harder to find, but offers excellent image quality and is built like a tank. While most macro lenses allow for high-quality images, different ones will meet certain needs better than others. Still uncertain about which lens to purchase?

I love the bokeh this lens produces. A third image was taken with the Sigma mm macro. I shot through several other flowers to give this image a colorful wash. This is another image taken with the Sigma mm macro. I shot through another coneflower to give this image a purple wash. Table of contents Macro Photography. Backyard Macro Photography Safari.
