Thanks for this video. I just jumped into photography and have a micro 4/3 Panasonic Lumix. After a lot of initial research I picked up a 25mm f1.7 prime lens to add to my kit, but I didn't truly understand why/how it is the equivalent of a 50mm full-frame lens. Now I understand that it's all relative to 35mm film standards which is the "full frame", and the crop factor of the 4/3 system being 2x smaller (and crop factor == focal length factor). I think also what was confusing me is that this is only focal length equivalence, not actual frame result equivalence since the aspect ratios are different.

MFT vs full-frame: the crop factor The Micro Four Thirds format is based on a sensor size measuring 17.3x13mm while the full-frame format is nominally 36x24mm. Do some sums and the diagonal of MFT measures 21.6mm against 43.2mm for full-frame, so almost precisely double, which gives us the 2x crop factor that is always mentioned in format comparisons. The 2x crop factor is important when we talk about lenses. A lens’s focal length is a fixed parameter so a 50mm lens is a 50mm lens regardless of the camera format in use. In practice, though, use a 50mm focal length lens on an MFT camera and you get the ‘equivalent’ field of view of a 100mm lens. This 2x crop applies to all focal lengths but the real practical benefit kicks in with longer focal length lenses, which is a plus point for fans of nature photography. A 400mm lens used on MFT gives the equivalent of a 800mm view (in 35mm equivalent terms). See our examples below. With both lenses a distant subject will be the same size, but on the smaller MFT format it will be more frame-filling compared with the 35mm shot which will need cropping to give the same composition.

Ooh Jim, I love this video breaking down the difference of a full frame and a medium as well as the breakdown of the crop censor on different cameras. I will watch this video several times until I can master the info. Thank you so much for sharing.

So what is the difference between apsc lens and full frame lens. Does using a 16mm apsc lens on an apsc camera will give actual 16mm or a 16mm with 1.5x crop

What Happens When You Attach a Full Frame Lens on APS-C Cameras? A full-frame lens is designed for full-frame cameras. But what happens if you take that full-frame lens, and mount it onto an APS-C camera body? In truth, not much at all. Focal Length First, the focal length of the lens doesn’t change. You see, the focal length of the lens is a physical property - it’s already fixed from the moment the lens is created. Focal length is the distance from a point inside the lens to the camera sensor, and this isn’t changed by a smaller, APS-C sensor. Depth of Field (DoF) Second, the depth of field doesn’t change. The depth of field is determined by the aperture, the focal length, and the distance from the lens to the point of focus; none of these are altered by an APS-C sensor. Image Quality Third, the quality of the lens stays the same. The optics of the lens remain constant no matter what camera you mount it on. However, there is one feature that changes with an APS-C sensor size: Lens’s Field of View You see, whenever you mount a lens onto a camera, the lens projects a circular image onto the camera sensor. This is known as the circle of projection. That circular image is always the same size, no matter the camera sensor. But the camera sensor doesn’t always use this entire projected image. A full-frame lens is designed to project an image that’s perfect in size for a full frame camera sensor. But when a full-frame lens is mounted onto a crop-sensor camera, the smaller sensor essentially crops the image projected by the full-frame lens and you end up with a narrower field of view; that is, you end up with a narrower portion of the scene captured by the sensor. Make sense? Advantages of Using Full-Frame Lens on APS-C Camera. Now that you know how a full-frame lens works on an APS-C camera, you can see that there is one big advantage to using this combination: The narrower field of view increases lens reach, so you’re able to shoot more distant subjects with ease. This increased field of view is often referred to as a crop factor, where a 100mm lens is cropped to a 150mm lens on an APS-C camera. (Despite this method of referring to APS-C cameras, the focal length doesn’t actually change! Only the field of view is affected.) This is important for wildlife and sports photographers, for example, because they often need to capture images of subjects far off in the distance. It increases their lens’s reach, even though the focal length doesn’t change. Disadvantages of Using Full-Frame Lens on APS-C Camera. There are a few important disadvantages to using this combination. For one, full frame lenses tend to be bigger and more expensive than their APS-C counterparts. Plus, while the extra reach is useful for sports and wildlife photographers, it makes wide-angle landscape photography a lot harder, because it nixes the ultra-wide field of view. That’s one of the reasons why many landscape photographers prefer to shoot full-frame, especially if their style involves creating ultra-wide, sweeping landscape photos. This affects your second question regarding shooting 16mm. You will loose some of your wider field of view. What Happens When You Attach an APS-C Lens on a Full-Frame Camera? In many ways, attaching an APS-C lens on a full frame camera is just like attaching a full-frame lens to an APS-C camera. Focal Length For instance, the lens focal length doesn’t change because just like a full-frame lens, the APS-C lens’s focal length is fixed from the moment it’s produced. Focal length is an optical property of the lens, completely unaffected by the sensor size. Depth of Field (DoF) The lens’s depth of field doesn’t change, either, because the focal length of the lens remains constant. Image Quality Even the quality of the lens doesn’t change; as I explained above, a lens’s image quality isn’t influenced by the sensor size. There is one issue with mounting an APS-C lens on a full-frame camera, however. Image Projection The image that’s projected by the lens is designed for APS-C sensors, not full-frame sensors so it’s smaller than required and doesn’t cover the entire full-frame sensor, thus affecting your 16mm question. Now, if you’re using Sony or Nikon cameras and lenses, then you can still mount an APS-C lens onto a full-frame camera. But you’ll often see vignetting (i.e., darkening) around the edges of the frame, which can easily ruin an image unless you crop it out. If you mount an APS-C lens on a full-frame Nikon and Sony camera and you don’t see vignetting, this is probably because the camera automatically identified the lens as APS-C and switched into a crop mode that uses only part of the sensor. This is a viable way of taking photos/videos, but you’re going to lose some resolution. After all, the camera is cropping out megapixels! Canon EF-S Lenses Issue Note that things get a bit trickier when it comes to native Canon lenses. If you mount a Canon APS-C lens (labeled as an EF-S lens) onto a Canon full-frame camera, the lens mount will ram into the mechanism inside the camera, which you want to avoid at all costs. This won’t be a problem with third-party lenses for Canon APS-C cameras, but native EF-S lenses simply should not be mounted on Canon full-frame cameras. Advantages of Using an APS-C Lens on a Full-Frame Camera Here’s the main advantage of mounting APS-C lenses on full-frame cameras.You can take advantage of smaller, cheaper APS-C lenses offered by manufacturers. These are often high-quality, but they cost much less than their full-frame equivalents. For instance, Nikon users often mount the (APS-C mount) 35mm f/1.8 lens on full-frame bodies. This lens offers excellent quality and a compact build for an impressively low price. Disadvantages of Using an APS-C Lens on a Full-Frame Camera When you use an APS-C lens with a full-frame camera, you’re only using part of the sensor. This, in turn, reduces the resolution of the final image. You’ll be forced to crop, or your camera will crop for you so that a 24 megapixel sensor produces a 10 megapixel image.
