#APS C LENS MEANING FULL#
The effect is that a 50mm full frame lens mounted on an APS-C body with a 1.5x crop factor will capture a field-of-view that is the same as a 75mm on a full frame body.įor Canon, this crop factor is 1.6x. This means your camera’s APS-C-size sensor magnifies the scene to produce an image that will match the lens’s full-frame image circle. When you mount a full-frame lens on a camera with an APS-C sensor you will get what is called a crop factor. This image circle collaborates with your sensor, and as such lenses are designed to be used with specific sensor sizes.Ī full-frame lens is roughly equivalent to a 35mm frame of film, while an APS-C sensor is a little bit smaller. Turn your lens around and you’ll see that lenses are designed with an imaging circle around the portion of the optic that mounts into your camera body. Worst of all is that crop lenses are not really cheap and there are not very many available, used and even new for that matter.There’s no denying the image quality produced by full-frame lenses, but when to use APS-C lenses instead of full-frame?
That won't happen with aps-c lenses since you are always punched in. You can also get more flexibility of fast primes if you go the FF way, 24mm to roughly 35mm in crop mode. video from my R IV is best at aps-c crop, but at its best it's still horrible in comparison to sampled full frame from my a7 III, night and day difference. crop, this varies a lot between cameras i.e. Say you want 24mm worth of field of view in 16:9, there are plenty of used full frame 24-70 lenses that are dirt cheap and very sharp for video, 16:9 ratio takes away the corners too so nothing to worry about in terms of vignetting (that would worry you for stills, maybe).Īnd then you get into the many sampling modes from full frame vs. If you already have aps-c lenses it makes sense, but I'd advocate for not buying aps-c lenses with intent to use them on a full frame camera, (actually had it, but returned it for a replacement this week, because of an issue, but like the gimbal a lot. I'm also a gimbal user, with the DJI RS2 but also getting the new DJI RS3 mini. Not cheap, but I plan to buy the Sony 16-35mm F4, which has a power zoom, making it ideal for video and is light weight and reviews state it's a good lens, albeit a bit expensive.
#APS C LENS MEANING MANUAL#
My Samyung 12mm is a manual lens, so it doesn't autofocus and I'd be a bit close to set it on one spot. I have a similar situation, having just bough a full frame Sony while still owning my crop sensor Sonys, but I don't plan to video myself while walking, but if I did, I don't own a suitable crop lens that would be wide enough. maybe 12mm, which would be the equivalent of an 18mm in full frame. Since you mentioned you wanted to walk around videoing yourself, you would want a wider lens. So if you buy a crop lens, you would want a wider lens, as when you apply the crop factor, then multiply the stated lens factor by 1.5 to figure out what your equivalent perspective is. What that means is the perspective of the image will be like using 1.5 factor, or a 36mm lens, thus your video image will not be as wide. If you used a 24mm crop lens, then that lens only uses the crop sensor size equivalent of the full frame camera.
so if it was a 24mm lens, the perspective of the video frame will be 24mm. One that comes to mind, is if you use a full frame lens, it will actually put the image across the whole full frame, and then downsample it to the video frame size. There are probably lots of technical differences, between shooting video with a full frame lens, versus a crop lens.
I'm not an expert, but I think for what you plan to do, it will be fine.
