Usually, that means superior image quality too. The answer is yes. Attaching your EF lens to a smaller sensor camera doesn't change its actual focal length. You're actually just less less of the image circle of the EF lens and getting a narrower angle of view. The challenge that comes with that is that your angle of view may be too narrow to fit the entire subject into your composition. Canon EF-S lenses do not work with full frame Canons.
It doesn't work. The lens mount makes it impossible for you to even mount the smaller EF-S lenses onto a camera body that requires a larger EF lens. The image circle of an EF-S lens is not big enough to cover the entire full frame sensor. If the mount did fit, you would have the corners of the sensor that would not receive any light when the shutter was opened. I'm a newbie at making videos, but this video will help you get a better understand of the differences between an EF and an EF-S Lens.
EF-S lenses don't have as wide of an angle of view relative to their focal length. Lenses, when used on a APS-C camera, "crop" into a full size image by a factor 1.
You should be familiar with the term crop factor. The best way to explain this is with an example. That means with an EF-S mm lens, it's angle of view is really equivalent to [ multiplied by 1. Here's a full explanation of crop factor published on my sister site. That was the same reason to introduce the EF-S lineup as well. EF-S lenses are cheaper compared to EF lenses. They are cheaper as they are made with cheaper materials.
They usually use plastic components instead of metal, and the glass is also not the highest quality. Next comes compatibility. We've discussed this in more detail below. The next difference is the target audience. EF-S lenses are primarily aimed at hobbyists while EF lenses are generally aimed at professionals. More specifically, the L series of EF lenses the ones with the red rings are premium quality lenses aimed exclusively at professionals, while EF-S lenses don't even have a professional lineup.
So, if you were wondering about its origins, now you know. Although, the results will not be the same in both cases. Read the next point for details. This is a bit tricky to understand. Physically, it is possible to use EF and EF-S lenses interchangeably, but that does not mean that you will get identical results with them.
Here is a simple matrix to break down what you can do. And a 50mm EF lens would be like mm. I understand that it cannot work the other way around, because it will create the vignette, etc.
The same occurs if I take a photo with the 50mm ef on the d and take a photo with the at 80 on the d. That makes sense because the lenses are restricted to non full frame cameras only.
In my opinion it is not accurate to state that for a wide angle ef-s camera on a Rebel line you will have a 1,6 plus factor.
You will get the exact factor that is on the lenses. It is only a problem when you use full frame lenses on cameras that are not supposed, like non full frame cameras. They all produce the same image size, regardless of the sensor size. The area covered depends on the lens design its coverage and the size of the sensor. Many posters confuse image size with field of view. All lenses with the same focal length produce an image of the same size and perspective. The field of view is then determined by the size of the film or sensor.
Just got Canon 7D with 50mm 1. I discovered that when I use the 7D with 50mm 1. The picture comes out blurring with a lot of noise.. What could be the cause please…. Hey guys. I guess I have a silly question. I also know from the video of the person above that you multiply the aperature as well in lenses when switching to a crop body sensor.
As you say, focal length is focal length. And, yes, an EF lens will cover any smaller sensor. Not no way, not no how. Aperture is aperture. This is all very trivial stuff. What changes? The focal length? The aperture? I am not a pro, but my understanding is that ef-s lens are specifically design for aps-c sensor camera. Lenses are base on 35mm camera. A 35mm lens mounted on a full frame 35mm camera theoretically would have a 35mm view. On an aps-c sensor which have a 1. I wonder if that 1.
Thanks for explaining this information. The fact that they hold value when upgrading is great knowing…. Thanks again! I understand the crop factor when using full frame lenses on crop sensor cameras. I do not understand why that still apples when using an EF-S lens which are built and designed for the crop sensor camera?
Then they recommend watching the video by Northrup where he says you do. And also he says you have square the crop factor and divide it into the pixels. My real question is, where do you go to get an answer you can trust? I do know one thing for a fact. When I put canon L full frame lenses on my crop sensor body I get better pictures. Why not just use the EF-S mount?
Hope this help clear things up cheers!. I have been using an SLR since I was 14, I got paranoind about quality and bought the best cameras and heaviest tripods and fastest lenses that I could buy. But now I an 63 years old.
I have much gear and someone must carry it around. Me I am fit for an old soul. It is all getting heavier. My DSLR gear is not small or compact. I still want fast lenses, which Canon can of course supply. The EFS lenses are really good enough for a non proffesional. Spend the few extra coins on Canon origional. You will not regret it. Infinity focus will be impossible. Thanks for jumping in David. This pretty much echoes what my response would be Doug….
A 50mm lens is a 50mm lens is a 50mm lens. The focal length of the lens does not change. This mount required that the autofocus motor be housed in the camera, rather than the lens. When EF-S lenses were first produced by Canon in the early s, there were already a huge number of EF lenses on the scene. While there is a wide range of EF lenses, many of them are designed with advanced amateurs and professionals in mind. Fortunately, it is possible to use an EF lens on a crop-sensor camera.
However, there are a few benefits and drawbacks to take into account:. For wildlife and sports photographers who require a lot of reach, this is extremely helpful.
While the narrow field of view on an APS-C camera may be appreciated by some photographers, others—primarily landscape and architectural photographers—will want the widest field of view possible.
EF-S lenses tend to stick out farther where they interface with the camera.
