This distance is crucial when switching lenses between different camera systems. There are adapters available to enable the use of lenses from one camera system on another camera body, but in order for the lens to focus correctly, the adapter must be able to match the flange distance of the lens and the camera body. The lens may not be able to focus at all or be able to focus to infinity if the distance is incorrect.

The first medium-telephoto macro E-mount lens with optical image stabilization. Impressively accurate life-size photography can be achieved in handheld shooting. A balanced approach is taken to correcting spherical aberration and other optical aberrations, resulting in the smooth, beautiful bokeh for which the G Lens series is known. Being able to shoot from a short distance away makes the lens a good choice for closeups of animals or insects that may run away if photographers get too close. Also useful for closeups of cherry blossoms and autumn leaves overhead.

The flange distance can be measured from the lens mount to the film plane in film cameras, in addition to the more common measurement from the lens mount to the sensor plane. The flange distance is measured to the actual focal plane in some cameras where the sensor or film plane may not be at the same distance as the mounting flange.

The best lens to use depends on the subject and scene you'll shoot. Check the minimum focus distance and working distance of the lenses you are considering.

A standard full-frame macro lens. Enjoy composing shots with broader-ranging backgrounds than medium-telephoto macro lenses. A versatile choice that can be used in serious macro shooting as well as culinary, landscape, portrait, and everyday photography.

Both APS-C and full frame cameras and lenses are offered, but as long as the same E-mount is used, compatibility is ensured. See the following page for notes on use.

Check the maximum magnification in the lens specifications to know how large you can make your subjects in shots. The maximum magnification is the magnification at which subjects look their largest, at the minimum focus distance. It's the ratio of the subject size as projected on the image sensor to the actual subject size. Macro lenses are designed to offer a large maximum magnification ratio. For example, a lens with a maximum magnification of 0.25x presents images with subjects one-fourth their actual size. Sony macro lenses offer maximum magnification of 1x, enabling full-size macro photography.

The construction of the camera body and lens mount determines the flange distance of a camera. It differs across different camera systems and even between models of the same system. For instance, a Canon EF mount’s flange distance is 44mm, while for a Nikon F mount it is 46.5mm.

The minimal distance that must exist between the lens and the sensor in order for the lens to properly focus is known as the flange distance, which is a crucial standard for camera manufacturers. For lenses to focus properly and create sharp images, this distance is essential. The lens may not be able to focus on infinity or it may focus outside of the sensor plane if the flange distance is off, producing fuzzy or out-of-focus photos.

For example, SEL30M35 lenses have a minimum focus distance of 9.5 cm and a working distance of about 2 cm. This allows you to shoot at very close range, so it's easy to take pictures of food or small objects on a table in front of you while seated. SEL90M28G lenses have a minimum focus distance of 28 cm and a working distance of about 13 cm. From a short distance away, you can take closeups of animals or insects that will run away if you get too close.

If autofocusing (AF) does not focus where you intended, either use direct manual focus (DMF) to fine-tune or manual focus (MF) to adjust the focus yourself. With DMF, you can fine-tune the focus using the focus ring after the camera focuses with AF. This way, you can quickly focus on the intended position.

Compared to conventional DSLRs, some camera systems, such mirrorless cameras, offer lower flange lengths. This makes it possible to employ adapters that can mount lenses from various systems without the need for extra optics or adjusting the lens’ flange distance. However, image quality and performance may be impacted by adapters that alter the flange distance or need for extra lenses.

This 1:1 macro E-mount lens is easy to carry and weighs only about 138 grams. Shooting subjects from the minimum focus distance of about 9.5 cm makes the lens a good choice for closeups of flowers and other small objects, as well as food on a table in front of you while seated.

For closeup views of small subjects, choose macro lenses. View intricate details through a macro lens—whether water droplets on plants or the movements of a mechanical watch—and you'll be enchanted by a world different from what you usually see. Macro photography is only one application for these fast prime lenses. You can shoot all kinds of scenes, including beautiful shots with bokeh, portraits, and street photography.

The focus ring on SEL90M28G lenses is also used to switch between AF and MF. You can quickly switch between these focus modes simply by sliding the ring forward or backward. To use DMF, set it to the AF position.

As lenses are adapted to various camera systems, the flange distance can have an impact on how well they work. For instance, mounting a lens too far from the sensor may come from adapting it to a camera with a shorter flange distance. This may affect the lens’s ability to focus and the quality of the images produced. In general, it is easier to adapt a lens with a shorter flange distance to a camera with a larger flange distance since the lens can be placed more closely to the sensor.

Although a variety of cameras and lenses are available, we're sometimes asked whether NEX-7 or ILCE-6000 lenses can be used with the ILCE-7C or ILCE-7M3.

The term “flange distance” describes the separation between a camera’s lens mount and the focal plane of its sensor or film. It is the distance, when the lens is mounted and focused to infinity, between the mounting flange on the camera body and the film or sensor plane.

Macro photography requires precise focusing. For a subject with conspicuous features all around, autofocus may not always focus on your preferred position if you open the aperture to blur the foreground and background and make the depth of field (area in focus) shallow.
