Canon is calling their latest EOS-1D digital SLR the “ultimate multimedia imaging solution.” The new Canon EOS-1D Mark IV has a 16.1-megapixel APS-H (1.3x crop factor) CMOS sensor and captures full-resolution RAW images at 10 frames per second and 1080p video at 30, 24 or 25 frames per second. The EOS-1D produced beautiful images the 1/16 foot-candle (or 0.67 lux) limit of my standard low-light test, even at ISO 100. Color is accurate and well-saturated, even at this very low light level. Your Canon is fine. The same happens to my Nikon D3 & D3X when I'm photographing a large flock of birds that's very far away. Living Wilderness wrote: I have used my 1D Mark IV extensively for wildlife for nearly three months now, and the only time I've had anything approaching a 30 percent failure rate is when I'm photographing a large flock of birds that's very far away. Similar with Nikon D3s, it has ISO performance of up to 102,400. Following is the official sample photos of Canon EOS 1D Mark IV, with 100% cropped photos. Lens used includes EF300mm f/2.8L IS USM, EF16-35mm f/2.8L II USM and EF100mm f/2.8L Macro IS USM. The highest ISO for this round is ISO 3200, higher ISo samples photos will be uploaded soon. A few folk seem to have developed problems with the latest 1d Mark IV firmware which I have now running and am using without any issues. A few sample and experimental images below - all in pretty poor light shot between ISO 800 and 2000 and note that even on 'still' subjects, I have used A1 servo to monitor focus stability and accuracy. As all-round full-frame DSLRs go, the Canon EOS 5D Mark IV remains an excellent DSLR and great value at its price. It’s even better value if you take the pre-owned route where you can expect to pay $1,039-1,320 / £1,039-1,259 depending on condition and the number of shutter actuations. All of this is thanks to the brand new 45MP image sensor, which Canon claims makes the R5 “the highest resolution EOS camera ever” – supposedly resolving even greater detail than the 50.6MP Canon EOS 5DS / R. This is thanks to the new low-pass filter design, which was introduced in the flagship Canon EOS-1D X Mark III. The Canon 1D Mark IV's 16-megapixel sensor captures a lot of image detail when coupled with a good lens, but images are slightly oversharpened at default settings. The EOS 5D Mark IV's high-speed readout technologies and DIGIC 6+ processor mean you can shoot at 7 fps at full resolution, with full AF / AE tracking. Shoot in varied lighting conditions An ISO range of 100-32000 (expandable from 50-102400) is combined with enhanced noise processing algorithms to further improve low light shooting.
