How Lens Adapters Work & Why You Should Try Them

With both Nikon and Canon switching out their DSLR markets for mirrorless platforms and offering up fresh lens mounts as a leave, and with Sony and Fuji both developing great lenses for their platforms, a coarse question we get asked is about lens adapters. And lens adapters are no newfangled thing, dating second at least a few decades nowadays ; I wasn ’ deoxythymidine monophosphate able to get an claim creation date. But as more time goes on, lens adapters have become an increasingly common thing for photographers and videographers alike – so lashkar-e-taiba ’ s talk about them .

What Are Lens Adapters?

Sony Camera Switch 1 When you first buy your television camera, whether it ’ s a DSLR or mirrorless television camera, you ’ ll have a lens mount organization on the front of it. This mount is designed to easily change lenses on your camera, switching focal length, aperture accelerate, and much more with a quick push button crusade and turn. These lens mounts are about entirely made of alloy, and are simple in design, with a few touch pins on them for the camera to communicate with the lens. While these lens mounts can ’ t in truth be changed ( though it has been done before ), but they can be adapted to work with a larger variety of lenses, through the habit of a lens arranger .

This means you ’ re able to convert Canon EF lenses to Sony E-mount cameras, Nikon F-mount lenses to their latest Z serial cameras, and in some cases, even change out lenses and cameras that have different detector sizes, like converting EF mount lenses to work on the Fuji GFX platform. With lens adapters, you ’ re able to switch camera platforms much easier, and even take some of your grandfather ’ s previous lenses found in a box in the loft for a tailspin.

How Lens Adapters Work

basically, the concept of lens adapters is bare. You know those pins and contact plates found on lenses and lens mounts ? All a lens ride does is reroute the data sent from those pins and ‘ translates ’ it so that your camera body reads the information delivered from the lens. This will ( normally ) allow you to use autofocus, give you correct f-stop readouts, and use the lens as if it was intended for the camera .
Those are electronic adapters, which have become far more popular in recent years that maintain the communication of the lens and camera, and surely the future of lens adapters – but there are mechanical adapters a well. These adapters are basically precisely a metallic element plate, where you mount your lens to one end, and television camera to the other. There is no communication between the two, so your EXIF datum will be blank when shooting. You ’ ll besides need lenses that allow you to adjust the aperture manually, in order to maintain the functionality and control of the lens .

SpeedBoosters & Specialty Lens Adapters

however, not all lens adapters are created equal, and some of them offer unlike features that can add interest effects to your prototype quality and lens sharpness. For case, there are lens adapters that can adapt lenses designed for smaller sensors that work on larger detector platforms, like an adapter that converts Canon EF lenses to an m4/3rd detector. The turn back is true excessively, so lease ’ s talk about how these work .
When converting a particular lens to a larger detector size than it was designed for, the term normally associated with these adapters is called ‘ Speed Booster ’ adapters, because they end up shortening the focal length, and giving you a larger f-stop. think of it as the opposite of a teleconverter adapter. A teleconverter will use a convex lens ( or magnifying lens ) to increase the focal length of a lens by a magnification of 1.4x, 2x, or even 4x. As a result, these lenses will gather less light up when shoot, and cause you to lose a stop of abstemious or more – count on the magnification flush. rush Boosters flip that idea on its head – putting a concave lens between the detector and lens, offering you a boil down focal length ( to better fill the detector frame ), and bringing in more light to the lens – giving you an extra barricade of light .
The resultant role allows you to drastically expand your lens handiness, while besides giving you some very singular effects. For exercise, I recently purchased an a dapter that converts Canon EF lenses ( designed for a 35mm full-frame camera ), onto my Fujifilm GFX medium format camera. Meaning I ’ m able to use fabulously low aperture lenses like the Canon 85mm f/1.2L II of a medium format – giving me something along the lines of a 66mm f/0.95 lens.

Other Speciality Lens Adapters

In addition to teleconverters and rush booster adapters, there are besides a few other adapters that will give you peculiarity properties that your lens or television camera backing might not already have. Among the most democratic of these adapters are the ones with built-in filters – with variable neutral density filters being the most common. I ’ ve talked about Neutral Density ( ND ) filters extensively in the by on this blog, but basically they limit the sum of light being entered into your lens, allowing you to blur movement, or even help lower your shutter accelerate so that you can use flashes more efficaciously on location. Having a filter at the base of the lens ( resulting in a much smaller percolate ) is inherently a more low-cost process, as it works as a one size fits all solution, and is smaller than most traditional filters. This is why it ’ mho common to see drop-in filter systems for large telephotograph lenses, like the Canon EF 200-400mm f/4L IS USM Extender 1.4x Lens .

Downfalls to Lens Adapters

obviously, having lens adapters isn ’ t all good newsworthiness with none of the bad. With each new component added to the equation, you ’ re adding more variables for what could go wrong. The biggest deficit of using lens adapters is that you may see some communication issues with your lens and the camera body. Apertures not changing, autofocusing cutting out, and incorrect data displayed on the camera and EXIF data are all more frequent when using an arranger ( though they have gotten much much better in holocene years ). If you ’ re using an arranger with a musical composition of glass in it, you will besides suffer image quality issues, but that may be minimal. Lens adapter brands don ’ t have the team of ocular specialists that Canon, Nikon, Sony, and Fuji do, so you ’ re likely getting a mass-manufactured objet d’art of glass in these adapters – though you ’ re likely to see more visualize quality issues at the longer focal lengths .
additionally, adding a lens adapter to your system is going to add size to your lens kit. While this may be borderline, if you ’ re using something like the Canon 200mm f/2L with a lens arranger, it will be far more noticeable when using a small 50mm lens. The size change of the system is identical much user-dependent, if you ’ re already bringing a full television camera bag of lenses to the event you ’ rhenium shoot, an adapter or two won ’ t make that big of a difference to your process – but if you ’ re using the Fuji X-T3 because you love its little phase agent, an lend arranger is going to change the dynamics of the camera pretty significantly .
In the past, I ’ ve called lens adapters a passage product – something you might buy to support your new Canon R5, while they develop more lenses for the RF series. however, as time has gone on, lens adapters have become manner more robust in design, and offer a batch of features that you might not see on traditional lenses.
