Finally, Olympus and Panasonic/Leica use a slightly different cropped format known as the Four Thirds system. The crop of the sensor varies a little between manufacturers as well. Most manufacturers' crop is smaller than a full frame sensor by a 1.6 ratio. But, Nikon's ratio is 1.5 and Olympus' ratio is 2. Things look great in both images, though, of course, the full-frame image has a slightly softer bokeh. The Panasonic 35-100mm f/2.8 on the left offers a similar picture to the Nikon 70-200mm f/2.8 (II) on the right. The Panasonic costs $1000 less, and weighs just 12.7 oz (360 g) (less than one pound!) compared to the Nikon’s 3.39 lb (1.54 kg).
Crop factor does NOT affect a lens’s focal length. Crop factor does NOT affect a lens’s aperture. 300mm f/2.8 with 1.4x = 420mm f/4. 300mm f/2.8 with 2x = 600mm f/5.6. If you take the Canon crop factor of 1.6, square it, and then apply it the sensor area difference, you'd get 9.4MP in the cropped full-frame image.
Fokal lensa ekuivalen. Pokoknya yang punya kamera APS-C (Nikon, Sony, Pentax, Fuji, Samsung) ingatlah, apapun lensa yang dipasang, akibat crop factor ini maka fokal lensa ekuivalennya adalah fokal lensa tertulis dikali 1,5 (khusus Canon APS-C kali 1,6). Khusus Olympus dan Panasonic kali 2. Dasar Fotografi dan Lighting. Moving from APS-C to Fuji’s medium format obviously brings a massive nearly 4x increase of sensor size, whereas you only get an increase of 1.67x vs. full frame. So you could expect that image quality-wize full frame and cropped medium format are roughly comparable and both visibly better than APS-C.
Focal length spreads it out, but for the same physical aperture diameter, the same amount of light is collected from an object in the scene. In the case of crop vs full frame, a common measurement is to change the lens to maintain the field of view, e.g. 50 mm f4 on 1.6x crop aps-c, and 80 mm for full frame.
APS-C and full-frame: 2 different-sized image sensors 2. Consideration #1: Impact on camera and lens sizes 3. Consideration #2: Low light and high ISO performance 4. Consideration #3: 1.6x crop factor 5. Consideration #4: Depth of field 6. In conclusion: APS-C or full-frame camera? APS-C and full-frame: 2 different-sized image sensors
35mm Lens on a Full Frame vs Cropped Sensor. For example, if you are using a lens with a focal length of 50mm on a camera with a crop factor of 1.5x, the effective focal length would be 75mm (50mm x 1.5). This can be advantageous for telephoto photography, as it allows photographers to achieve more magnification without the need for longer lenses.
2,360+ Photography Guides & Gear Reviews Full Frame vs. APS-C Cameras (7 Key Differences to Know) Full frame vs. APS-C: which camera sensor is better? Both types have several downsides and advantages. Check out this guide to learn more. Camera Gear Guides | By Jeff Collier Get the full-frame (35mm) equivalent focal length and aperture for different sensor sizes. Just enter the focal length and maximum aperture of your lens and then choose a sensor size. My mm f/ lens, on a Micro Four Thirds Canon APS-C Nikon APS-C APS-H Cropped Medium Format Medium Format sensor, is equivalent to a 157.5 mm f/ 2.1 lens.
So, what does all this mean? Well, because the focal length for just about any lens uses a 43.3mm diagonal sensor as a reference point, a much smaller sensor with the same lens only capturing the center of the image would make the image appear much more zoomed in. The image below compares full-frame sensors with APS-C sensors.
OR you can attach an EF-S lens (same mount but opening tailored for the smaller sensor) which holds the focal length true for the APS-C sensor. When inputing the focal length above for a EF Full frame lens attached to the APS-C sensor, I have do the 1.62x calculation first, correct? i.e. an EF 30mm would be effectively a 48.6mm on the APS-C sensor.
Remember, the focal length given represents the result on a full frame body. Let’s take the example of a 50mm. It doesn’t matter if it was originally designed for APS-C or FF format, the focal length of a lens doesn’t change. It is the field of view that varies depending on the size of the sensor on which you place the lens.
Lens A (full-frame 50mm prime lens) will shoot equivalent to a 75mm focal length Lens B (cropped-sensor 50mm prime lens) will shoot equivalent to 75mm focal length as well APS-C/Super 35mm – AUTO zfKZO86.
