🦖 Full Frame To Aps C Lens Conversion
An illustration showing how the same lens will produce a wider angle of view on a full frame camera compared to an APS-C camera, and how a 70mm lens on a full frame is the 35mm equivalent to 50mm
The new Samyang AF 12mm F2 is an autofocus version of this formula for Sony E-mount (APS-C mirrorless), and also comes with a new build and fresh design language that is slightly different than anything I’ve seen from Samyang before. It’s great to see Samyang give some fresh love to APS-C, and the 12mm F2 gives an approximately 18mm full
Diagonal fisheye: Possible on full-frame and APS-C. EOS R + EF8-15mm f/4L Fisheye USM @ 15mm. Regardless of whether you use an APS-C or full-frame camera, you still can get a dynamic effect with the diagonal fisheye effect, which appears from around 12mm full-frame equivalent on a fisheye lens. It’s not just about the unique distortion.
I've got a question regarding focal length conversion of lens to/from APS-C sensors: Full frame lens to APS-C: 1.5(ish) X focal length I get that since we're taking a larger area, and cropping it down by (theoretically) making the focal length of the lens longer, to bring down to the smaller sensor size of APS-C cameras
In fact APS-C sized sensors (found in cameras like the C300, 7D, etc.) are the closest digital equivalents to real 35mm motion picture film, so technically if you want to stay as true to 35mm cinematography as possible, you should be shooting on APS-C sensors (which have a crop factor of about 1.6 when compared to full frame).
For example, APS-C cameras typically have a crop factor of 1.5x or 1.6x. Since the GFX system has a sensor that is larger than full-frame, we can expect our crop factor to be less than 1. In other words, 35mm full-frame equivalent focal lengths will be wider than the quoted focal length for any given GF lens.
APS-C Speed Booster Nikon F Manual Focus Lens Adapters. Speed Boosters are 0.71x focal converters that reduce a full-frame image to APS-C. They’re compatible with Sony APS-C mirrorless cameras including a5000, a5100, a6000, a6100, a6300, a6400, a6500, a6600, FX-30 and NEX.
For Micro Four Thirds lenses, that would mean: Panasonic-Leica 25mm f1.4 would be equivalent to 50mm f1.4 on full frame, f2.8 equivalence in Depth of Field (DoF). Panasonic-Leica 42.5mm f1.2 would be equivalent to 85mm f1.2 on full frame, f2.4 equivalence in Depth of Field.
Approximately equivalent to 1.6 x the lens focal length. APS-C size. The shooting screens of the APS-H size camera and APS-C size camera have smaller designs than the shooting screen of the 35mm half-frame camera. For this reason, the 35mm-equivalent focal length and the focal length image of the mounted lens are as follows:
At the end of the day, there is one and only one implication of the crop factor: the field of view is narrower on APS-C compared to full frame given the same lens. The crop factor itself is found by dividing the length of the diagonal of the 24 x 36 mm sensor (43 mm) with the length of the diagonal of the APS-C sensor (28.8 mm): 43 / 28.8 = 1.5.
Simply multiply your aperture, just as you would your focal length, by your crop factor to find the equivalent full frame aperture. So, a 35mm f/1.8 on APS-C is roughly equivalent to a 50mm f/2.8 on a full-frame camera. You could, however, shoot with the same lens, at the same aperture, from the same distance, and get the same depth of field
Because cropped sensor cameras have a smaller sensor, the actual focal length won’t be the same as on a full-frame. To make this easier, let’s look at some examples of focal lengths: 35mm = 52.5mm on a cropped sensor. 50mm = 75mm on a cropped sensor. 85mm = 127.5mm on a cropped sensor.
