The EOS-1Ds is Canon's newest professional SLR. Based on the EOS-1D body the EOS-1Ds raises resolution to 11 megapixels, uses a CMOS sensor (just like the EOS-D30 and D60) and is the first Canon digital SLR with a sensor which captures a full 35 mm frame. Lets examine more in depth at the Canon 1D vs Nikon Z9, former being a Pro DSLR while the other is a Pro Mirrorless by brands Canon and Nikon. There exists a sizable gap among the resolutions of the 1D (4MP) and Z9 (46MP) and the 1D (APS-H) and Z9 (Full frame) enjoy different sensor measurements. The example above shows a 35mm film frame. I've drawn boxes on top of it in the sizes of popular digital cameras. The green box is the sensor size of 1.3x factor cameras, which are the Canon 1D series. The red box is the size of the 1.5x factor sensors in the Nikon digital SLRs. The blue box is the size of the Canon 1.6x consumer cameras' sensors. Full-frame and cropped 4K? Yes, the 1D X Mark III offers full-frame 4k with no crop. This is big for Canon; we are glad they are keeping up with their contemporaries. Along with full-frame capture, there is also a pixel for pixel DCI 4K option with a 1.3 times crop. We found some performance differences between the full-frame and cropped mode The Canon EOS-1D X Digital SLR camera is scheduled for March 2012 availability and will be sold in a body-only configuration at an estimated retail price of $6,800.00. The compact, lightweight WFT In full frame 4K/60p and 5.5K RAW / 60p, one of the biggest features of the 1D X Mark III – the autofocus – packs up and goes home for reasons only known to Canon. Canon advertise this as a superb autofocus camera. Nothing comes closer to the classic 1D C look or handling as a highly video capable DSLR. C) It is the only full frame stills camera that does 10bit 4K/60p and 12bit 5.5K RAW internal recording. Although Panasonic S1H runs it VERY close. D) There is no other full frame 10bit camera on the market with as capable autofocus in video mode The Sony Alpha a7 IV is simply one of the best full frame cameras on the market. Moreover, as one of the best digital cameras, it has the power to beat DSLRs at their own game. This monster comes with a 24 MP resolution and a hybrid AF system. The latter has a whopping 399 phase-detection points and 425 contrast focal points. Canon EOS-1D C Specs. Announced Apr 12, 2012 • Full frame (36 x 24 mm) Sensor type CMOS Processor Dual Digic 5+ See our full motion performance review, including video clips. We found the Canon 1D X was able to produce sharpness results of approximately 700 lw/ph vertical sharpness (around 600 lw/ph horizontal) with the 24-70mm f/2.8L series lens stopped down to f/9. We found the sharpness was much worse with the lens wide open, but there is still 9sIdo.
