That really confused me until I worked out that they’d reused the name of a defunct film cartridge for a sensor size. https://en.wikipedia.org/wiki/Advanced_Pho

- neilv 4y agoFor many years, prosumer DSLRs have been said to have "APS-C" size sensors. Or "1.6x crop factor", or "1.8x". That's a a multiplier for effective focal length, relative to using the same lens on a 35mm film body. DSLRs with sensors the same size as 35mm film were called "full frame".
- bayindirh 4y agoAPS-C crop factor is around 1.5x - 1.6x. 1.8x is a bit too small for digital cameras and I never encountered one. Canon uses 1.6x, and everyone else is on 1.5x bandwagon.
- TaylorAlexander 4y agoMicro Four Thirds is a 2x crop factor and I absolutely love my Panasonic GH-5. I primarily use it for 4k video which it excels at, as the smaller sensor means it can record 4k at high bitrate continuously without overheating. That said I still find it extremely rewarding for still photography. I'm happy with the results event when printed up 13"x19" on my Canon Pro-100 printer. Some photo samples I am proud of, limited to 4k resolution by twitter but 20 megapixels originally. https://twitter.com/TLAlexander/status/1531837629938798592 https://twitter.com/TLAlexander/status/1531837629938798592
- hef19898 4y agoSmaller sensor are the best teleconverters one can get, aren't they? Nice pictures, really something to aim for!
- bayindirh 4y agoAh, sorry, I meant in APS-C world, sorry for the confusion. I love m43 systems, but their low light capabilities leave something to be desired. I shoot tango nights sometimes, and anything smaller than a FF system can’t keep up with the lack of photons, unfortunately. Other than that, they’re brilliant little systems. There is some stuff I shoot: https://www.flickr.com/photos/zerocoder/ https://www.flickr.com/photos/zerocoder/
- eropple 4y agoFWIW, low-light performance has significantly improved in the last couple of m43 generations. My G9 (with a sufficiently wide-open prime) gets shots that my G7 and GH4 never had a chance for, and while the GH6 isn't great as a stills camera I expect to see even better for the photo-focused cameras using that sensor.
- bayindirh 4y agoI understand, and certainly support improvement in every size and family. However, when you're trying to shoot movement with 1/60, f/2 @ ISO10K, nothing smaller than FF cuts it. It's almost pitch dark and flash is strictly prohibited.
- Gravityloss 4y agoAn F/1 25 mm m43 lens would capture the same photons as an F/2 50 mm full frame one. Certainly an F/1 level m43 lens is a lot harder to find, I'm only aware of fixed focal length manual focus unstabilized ones...
- bayindirh 4y agoHowever, the noise floor on these m43 sensors are nowhere near the full frame counterparts, unfortunately. Getting same resolution requires much smaller pixels, too. I love more compact systems, but we can’t bend physics, for now.

- neilv 4y agoThanks, I meant 1.6x and 1.5x. (Was a Canon person, and loved the reach of the 70-200/4L on 1.6x so much, that I never wanted to go to full-frame.)
- bayindirh 4y agoThey reused it because the sensor size is equal to that film cartridge’s frame size. Same for full frame. That’s equal to 35mm film.
- nakedrobot2 4y agoUh, 20 years ago.
