Reviews Word on the street for the Canon EOS 1D Mark IV

The USB connector becomes a combined digital and A/V output, freeing up room for a stereo mic input and HDMI socket for users of the camera's movie capabilities.

Like its predecessor the EOS-1D, it has a 1.3X lens conversion, or crop factor, because its CMOS sensor is smaller than a 35mm film frame.

What People Are Saying Give it to me straight


This cleaner processing, combined with the sensor's higher resolution makes the result pretty convincing.
by DPReview (Feb, 2010)
Frankly there's more to both cameras than just their high ISO performance and, while the Mark IV isn't the best high ISO camera on the market, it's still an exceptionally good one.
by DPReview (Feb, 2010)
The main difference between the 1D Mark IV and the Nikon D3S is clearly sensor size and pixel count.
by DPReview (Feb, 2010)


Those problems, which appear to have come from a combination of manufacturing error, increased complexity of AF customization and the AF sensor occasionally being overwhelmed in bright conditions, have become notorious.
by DPReview (Feb, 2010)
In automatic AF point selection mode the camera will highlight (glowing red) the AF points which were used to measure AF distance (you can turn them off using C.Fn III-13).
by DPReview (Feb, 2010)
The AF point selection method has also been revised, both for manual selection and for automated selection with subject tracking via the new AI-Servo II system.
by DPReview (Feb, 2010)


The NR Strong setting is very aggressive at all ISO settings, so we'd be tempted to use NR-Standard when working above ISO 6400 and Off or Low below that.
by DPReview (Feb, 2010)
Ultimately, though, the 1D Mark IV performs well enough in low light that we were able to comfortably shoot sports in light requiring ISO 25,600, and that's not a sentence we can write about many cameras.
by DPReview (Feb, 2010)
But if the corollary of that statement is that we consider ISO 25,600 to be perfectly usable then we think it's going to sound pretty good to the Mark III shooters limited to 6400.
by DPReview (Feb, 2010)


The complexity issue is addressed in greater depth in the AF section of the review - the AF setup is simply the most prominent example of a system that you'll get more out of if you learn about it in some depth first.
by DPReview (Feb, 2010)
In One-Shot AF mode the camera is simple to use and it's easy to select the point you wish to use.
by DPReview (Feb, 2010)
Turning the main dial moves the AF point laterally across the frame, while the rear dial selects the AF point above or below the current one, rotating about the central point.
by DPReview (Feb, 2010)


The movie shooting version of view view is very much like the one for stills shooting, with a choice over how much information is displayed.
by DPReview (Feb, 2010)
And, while the Mark IV's handling may be approaching the zenith of what any stills shooter might desire, it is pretty clear it isn't a camera designed for video shooting.
by DPReview (Feb, 2010)
The EOS 7D features a dedicated switch to change from other shooting modes to movie mode.
