What is the difference between ef and efs lenses

Also, note that different lens mounts are created by the same manufacturer. This might be for fundamentally different camera systems such as mirrorless versus DSLRs , but it could also be for different types of lenses within similar camera systems such as full-frame versus APS-C. EF lenses go all the way back to , while EF-S lenses are much newer they were created in Prior to using the EF mount, Canon had been producing cameras and lenses that interfaced through the FD mount.

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.

Hopefully, you are now aware of which Canon lenses are compatible with your camera. As to which lens you should buy, my suggestion is to buy the one that fits your needs. Quality EF-S lenses hold their resale value just fine. Buy the lens that fits your needs now. If that means you want a massive EF telephoto lens, then go ahead. If you upgrade to a full frame camera later, it will work fine. You can hang on to your EF lenses, sell your EF-S lenses and buy their full frame equivalents after you upgrade.

This particular ES received rave reviews and does not disappoint. Common sense??? Most photographers just want to take great pictures.

My first father in law was George Cernik. George Cernik traveled all over the world with Harvey Firestone. I had nearly five years with George before he died. The 35mm BW film was nearly free. Developing at FTR was free. My answers sucked. In eight months my answers resolved the variables. The depth of field questions were added. I bought a EF Some info on the interned are frequently nerdy, unclear and complicated too.

Unless we know which questions too ask, how are we to learn without looking as though we have no common sense? Lots of info about the 1.

Looking at a 2. This has been argued ad nauseum. End of story As I understand it; I never tried it. You are right if you only could mount the EF-S lens in a full-frame camera. Mounting a lens designed for a camera with a small sensor or film format on a camera with a larger sensor or film format introduces major problems. I think the Rebel line will be completely adequate for me.

Norm, I have 4 of the Rebel line cameras and they have worked beautifully for me over the years, I am thinking about upgrading but after reading all these comments, I will definitely take my time and do the research to make sure that the lenses I already have will fit my next camera. I was told a long time ago that any Canon lens would fit any Canon camera…not true!

You live and learn, I should have researched that myself. Which one is it? I guess I always assumed that the number on the EF-S lens was adjusted already since they are designed for the smaller sensor. So that assumption is wrong? I guess once I get a few EF lenses I can find out. Your prior assumption is wrong. There is no adjustment on the focal length label of the EF-S lenses. The variable when switching between lenses is the sensor size. The crop factor we are talking about is brought into play because the Canon Rebel series has a smaller sensor.

The angle is determined by the trigonometric not arithmetic relationship between the sensor's diagonal measurement and the lens's focal length. A 50mm lens has a degree diagonal angle of view on a Canon Rebel. An 80mm lens has a degree diagonal angle of view on a Canon 5D. The crop factor refers only to image size. It does not have a linear relationship with the angle of view. Most photographers have a poor technical grasp of photographic principles.

Or that red, blue, and yellow are the color-printing primaries. I will continue to describe the term in the way it is accepted in the industry and the way Photography Bay readers can better understand how to use their cameras. It is you who are complicating the issue, by giving an incorrect and unneeded explanation. The following is probably the simplest way to explain it in words. A drawing is better.

It sees less of the image than a full-frame sensor would see, so objects in the field of view are therefore larger when both images are viewed or printed at the same size. The smaller the sensor, the larger the crop factor. Can I get a Ef85 for a canon t5i and get distance from subject but still keep sharpness or the 50mm n be close to subject can anybody help. If I photograph a subject at say 3m with an 85mm lens on any camera, of any format, the linear size of the image at the film plane will be the same.

It is not affected by anything other than the focal length and the distance from the subject. This is Photography , and should be explained in any good book on photography. I learned it 50 years ago in a book by Andreas Feininger. Both lenses work fine on the Rebel T5i. 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. Also, you don't need to apply the crop factor to the focal length as many people suggest.

As for the image quality, that depends on the glass itself. You would think that a simple abbreviation like EF-S would mean a single thing. But, surprisingly, that is not the case. Canon did publish a technical report about this, but the link has been dead for some time. However, you can view a copy using the way-back machine. 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. Second, just read the printed writing on the lens itself. Finally, you can look at the size of the opening on the camera end of the lens. The EF lenses have much bigger internal diameter and lens opening near the camera.
