Canon EF vs. EF-S Lenses. What is the Difference?

Canon EF vs. EF-S Lenses. What is the Difference?

Enthusiast photographers are choosing between these two types based on lens compatibility with body type and desired focal length. New EF and EF-S lenses made by Canon are both sold with their significant Canon DSLR cameras. Each lens serves a different purpose, depending on the camera body it is used in conjunction with.

Benefits of Canon lenses:

  • Professional-grade glass and coatings for optimal image performance;
  • Superior durability and all-weather performance;
  • Consistent and intuitive controls for more efficient workflow;
  • The smallest, lightest, and most affordable high-quality lenses;

Many photographers are not sure what the difference between the lenses in the Canon’s E-lines is, and which one they should purchase for their camera. A few major differences that you need to know before deciding on which lenses to buy for your camera!

What are EF Lenses by Canon?

Canon EF stands for full-frame and super versatile lenses. They’re also very easy to use, reliable and can be used on a variety of Canon cameras. If you don’t have an EOS camera body yet, these lenses will operate with it as well! Additionally, if you own other brands such as Nikon or Sony but want to switch over to Canon for your photography needs – these lenses should do the trick too.

Basically, all this lens is missing is the “S” at the end of its name because that would indicate that they were designed specifically for APS-C sensor cameras (think of crop sensors). But don’t worry, this lens is fully compatible with crop sensor cameras too! It just won’t have the same magnification as it offers on a full-frame camera.

EF lenses by Canon are also ideal for videography work because they offer fast autofocus performance that works well in most situations.

What are EF-S Lenses by Canon?

While EF lenses can be applied on crop sensor cameras as well – it doesn’t operate on other camera bodies. Unfortunately, that means Canon EOS camera bodies without full-frame sensors will never accept this type of lens due to its size mismatch. However, there is another option! That’s where Canon EF-S comes in handy since it was specifically created for use with APS-C (crop) sensor DSLR cameras such as the 70D or 80D.

Canon EF-S lenses feature a smaller design that’s much more compact than their full-frame counterparts. This makes them all the better for use with crop sensor DSLR cameras, which typically lack the same size and weight properties as full-frames. It also helps to make this lens less expensive (due to cheaper material costs) since they were designed specifically for APS-C sensors – but don’t think you’re missing out on quality just because it’s an “EF-S”.

What Lens Type Will Fit Your Canon Camera?

What cameras will fit an EF lens?

Canon EF lenses are the larger, full-frame (FF) lenses. They are compatible with DSLR cameras that also have APS-C or FF sensors like those found in many of their most popular models such as the EOS 80D and 77D. EF lenses will work great on these Cameras because they are equipped with a short back focus distance, which makes it easy for them to achieve infinity when paired with an APS-C sensor.

What cameras will fit an EF-S lens?

EF-S lenses were made specifically for cameras with APS-C-sized image sensors. They simply won’t work with full-frame or 35mm format DSLR bodies, but they will work on all EOS Digital SLRs including the Rebel series and Canon’s line of PowerShot digital point & shoot models.

The main benefit to using an EF-S lens over a regular EF is that it has a smaller internal flange distance that allows them to be much more compact than similar focal length “EF” lenses. This makes them ideal for use on small camera bodies like those found in most entry-level consumer/prosumer DSLRs today as well as super zoom bridge-style cameras where every millimeter counts!

How to Identify EF and EF-S Lenses?

EF lenses were specifically made for full-frame DSLR cameras by Canon. You can use them on any of the company’s EOS models, whether they’re APS-C or full frame.

EF stands for “electro focus”. They can autofocus without an adapter and feature a rear focusing design that increases the speed at which you lock in your subject. They also have electronic contacts so camera bodies can communicate with each other to control aperture settings among other things. This allows some older film SLRs like the original EOS D30 to continue using manual exposure modes even if new digital cameras lack mechanical dials.

How to Identify EF and EF-S Lenses

EF-S lenses are designed for cameras with APS-C size sensors. They can be used on EOS models that feature both APS-C and full-frame sensors, but they will vignette when mounted to a camera body featuring an even smaller sensor than the one found in their lens mount.

The difference is that these optics only come in fixed focal length designs (no zoom) which means you typically get less glass inside of it since there isn’t space taken up by moving components such as gears or optical elements inside the barrel itself. This allows them to maintain compact dimensions while boasting impressive image quality across their faster f/ratio ranges.

Key Differences

EF and EF-S lenses are equally considered smart DSLR lenses. The major difference between the two is that they have different mounts to fit on a different line of cameras. Canon has two main lines: EOS for full-frame, and EFS for APS-C (crop).

If you’re using an APS-C camera like a Rebel/Rebel TxxD or 80DX, then you’ll need an EF-S lens because it won’t physically fit onto a full-frame body such as the new M50 mirrorless camera from Canon. If your current mount is going to be permanent – for example, you’re only using the camera for landscapes and will never switch to another mount – then it may be worth spending more on an EF lens.

Key Differences Between Canon EF and EF-S Lenses

The other thing that separates Canon EF from Canon EF-S is that the latter are not full-frame lenses. Both E-line lenses were made specifically for crop sensor cameras so they don’t provide as much coverage of a wide-angle shot or zoom in as closely. If your goal is to shoot photos where there isn’t any zooming necessary (landscapes), this won’t matter much but if you plan on shooting indoors or with wildlife/sports, you’ll want at least one full-frame lens later down the road anyway.

FAQ

Can you apply an EF lens on an EF-S-ready camera?

Yes, an EF lens will operate on any EOS camera that has a compatible mount. The only exception is the full-frame 80D and 77D cameras which have a smaller EF-S “APS” type sensor so you can’t use lenses with this design. All other Canon DSLR cameras are fully compatible with all of their own lenses as well as those from every first-party manufacturer such as Sigma, Tamron, and Tokina.

Can you use an EF lens on a 90D?

No, 90Ds use EF-S lenses. EF lenses were specifically made by Canon for their full-frame cameras like the EOS-S. On the other hand, EF-S lenses tend to be smaller, lighter, and only work on camera bodies that have a sensor size of APSC (EF-S).

There are no performance differences between EF and EF-S lenses because they both project images onto the same sized image plane inside your camera (the back of the mirror box). An advantage to using EFs or larger lenses is their increased maximum aperture.

What is Canon EF-S 55 250mm used for?

Canon EF-S 55 250mm is used for taking photos of sports, wildlife, and other similar objects from afar. It can also be useful when you need to take a picture on the move without being noticed too much by your subject. The lens has an Image Stabilization feature that will help to eliminate image blur caused by shaky hands while shooting in low light conditions or at long focal lengths.

Also, Canon EF-S 55 250mm can become a great addition to your collection of lenses if you like taking pictures of cars, motorbikes, and other such objects. It will provide high image quality at the long end (in the telephoto range). If needed, it can be used for close-up shots as well. Although only a few people use this lens for portraits or weddings because there are better alternatives in these categories: Canon EF 50mm f/28 and Canon 100D 3300 IS USM, respectively.

The optical stabilizer lets you take sharp photos even with slow shutter speeds. Because of the Image Stabiliser, you can also shoot handheld at low light conditions with high ISO sensitivity settings and fast aperture values (wide open) that would otherwise result in blurry images caused by camera shake.

If you are looking for a lens to take photos on the move without drawing too much attention from your subject, this is probably not what you need because it does not autofocus quickly enough to keep up with sports or wildlife moving very quickly. You will be better off buying Canon EF 100mm f/22 USM that has an ultrasonic motor built into the focusing mechanism resulting in faster, more accurate autofocus.

Can you apply EF lenses by Canon on mirrorless cameras?

EF lenses are too big for mirrorless cameras. This brand has a special line of smaller and cheaper EF-S lenses that you can use on your EOS M series camera. But they have one serious downside: the crop factor is huge! An 18mm lens acts like a 28mm, 50mm behaves as an 80mm, etc.

The reason why these lenses exist at all is that most people who buy them already own DSLRs with APSc sensors (more about sensor sizes below). By keeping compatibility between their old equipment and the new ones, the company guarantees sales from its existing customers. It’s actually very smart business thinking when you think about it this way.

Can you use EF lenses on EOS?

One of the most common questions asked by beginners is whether or not they can apply EF on EOS cameras. The answer to that question is both “yes” and “no,” depending on what type of camera body you have. Canon has produced several generations of cameras for its SLR line over the past few decades. Each one uses a different lens mount – the physical connection between your camera’s body and the glass in front of it.

Do EF lenses work well on EOS R?

Yes. EF lenses operate quite well on EOS R. However, there are a few limitations due to the electronic mount of the cameras and some issues with autofocus.

It is possible to use EF lenses on an EOS M body via an adapter. However, please note that they cannot be used for video capture or continuous AF, as these features have been disabled in-camera when using this type of lens/adapter combo.

Is it possible to apply an EF lens on APS-C?

Keep in mind that EF lenses are only compatible with specific Canon cameras that have a full-frame sensor. An APS-C camera has a smaller CMOS, which means the focal length of any EF lens will be multiplied by the x crop factor (e.g., an 18mm lens on a full-frame body would give you a 27mm equivalent field of view).

However, some photographers prefer to use their original DSLR lenses for compatibility and quality reasons — especially if they’ve invested in high-end glass-like L series or Zeiss Milvus primes! As such, there is no downside to using your EF lenses on these bodies; however, it may limit your ability to get wide-angle shots due to perspective distortion shooting at low angles.

Are RF lenses by Canon better than EF?

Canon RF lenses are better than EF. RF lenses have a longer back focus distance and may not be suitable for macro shots since they’re optimized to work best on full-frame sensors. In other words, the lens won’t focus as closely when paired with an APS-C sensor camera body. Canon has several options in this category including the RF 35mm f/0.95 IS Macro and 100mm f/STM Macro. The latter features Optical Image Stabilization (OIS), Nano USM technology, and stepper motors that make it ideal for shooting video footage.
