By dropping resolution on its full-frame CMOS sensor to 18-megapixels (a compromise between the 1D Mark IV’s 16.1-megapixel APS-H sized sensor and the 1Ds Mark III’s 21.1-megapixel full-frame sensor), not to mention its new Dual Digic 5+ processors, the 1D X is able to shoot at even faster rates than the speedy 1D Mark IV—12 fps Subsequently, the ten-million-pixel Canon EOS-1D Mark III, with its sub-full-frame (APS-H-sized) sensor, started to lose its appeal despite its 10fps shooting rate. Unfortunately for Canon, many professional photographers chose to switch systems and use Nikon equipment. Clearly, Canon has learned a few lessons in the intervening period. Back in August 2005 Canon 'defined a new DSLR category' (their words) with the EOS 5D. Unlike any previous 'full frame' sensor camera, the 5D was the first with a compact body (i.e. not having an integral vertical grip) and has since then proved to be very popular, perhaps because if you wanted a full frame DSLR to use with your Canon lenses and you didn't want the chunky EOS-1D style body In 2020, Canon introduced the EOS-1D X Mark III as a successor to the EOS-1D X Mark II. It uses a similar, but improved, 20.1 Megapixel CMOS image sensor. It is a stop higher in sensitivity and has lower noise, primarily due to a new and more powerful DIGIC X processor. Autofocus has been elevated on a number of fronts. 1. Canon EOS R3. The Ultimate Professional Canon Camera, Incredibly High-Performing. When getting the shot is imperative, the extreme EOS R3 is the camera to pick up. While the R3's 24 MP resolution is not high for a full-frame camera, the quality of those pixels is so high that it outperforms higher resolution models. Featuring a newly designed 20.1MP full-frame CMOS sensor and updated DIGIC X image processor, the Canon EOS-1D X Mark III is capable of continuous shooting rates up to 16 fps with the optical viewfinder or 20 fps in live view, with a 1000-shot buffer when shooting raw+JPEG, and it has the ability to internally record 5.5K RAW video and 1D X, II, III: Merges the 1Ds and 1D series together; high speed shutter, fast autofocus and full frame sensor with excellent image quality. Advanced video features as well. 1D C: The first DSLR with 4K video recording and more advanced video features (Discontinued) Model number 1 E.g., EOS-1D Mark II, EOS-1V, EOS-1Ds Mark III, EOS-1D X Mark II The 5D Mk III does not have an automatic crop mode like some other cameras do. The 22.3 megapixel image size makes it easy to get nice crops if you don't mind doing it yourself. msowsun's gear list: Canon PowerShot S110 Canon EOS D30 Canon EOS 5D Mark III Canon EOS Rebel SL1 Canon EOS 80D +27 more.
