Canon announces 16.06 million image pixel EOS-1D Mark IV

Canon has revealed the details of its next 1-series digital SLR, the EOS-1D Mark IV. The new model is an evolution of the EOS-1D Mark III and features a 16.06 million image pixel, 1.3x crop sensor, top ISO of 102,400, 1080p video with external stereo mic jack, a revamped 45-point AF system and a wider-gamut, 920,000-dot rear LCD. All of this is inside a body that's essentially identical in appearance and control layout to the camera it replaces.

The EOS-1D Mark IV

The transition from the EOS-1D Mark II N to the EOS-1D Mark III was big. Photographers who bought the 10.01 million image pixel, 10fps digital SLR starting in late-May 2007 were getting a camera that bore little resemblance to the camera that came before. Inside and out, almost every component of the EOS-1D Mark III was new.

This time around, Canon has been more selective in what it has changed and what has remained the same.

First, they've kept the EOS-1D Mark III body intact, except for minor tweaks. Side by side, the two models are nearly indistinguishable. Outwardly visible changes include a new nameplate and mic on the front, several subtly reshaped buttons and a speaker on the back, a reworked arrangement of ports and port covers on the side (including a flap rather than a screw cap for the wireless transmitter mount) and minor tweaks to the information displayed inside the viewfinder, on the top panel LCD and the lower rear LCD.

The photos below of the EOS-1D Mark III and EOS-1D Mark IV tell the story.

Second, they've left either untouched or only mildly tweaked many of the EOS-1D Mark III's core components in the move to the EOS-1D Mark IV. This includes its viewfinder, 63-zone meter, 300,000-cycle shutter mechanism, twin CompactFlash and SD card slots (though CompactFlash write speed is promised to be dramatically quicker), LC-E4 battery and support for Canon's side-riding wireless transmitter, the WFT-E2/E2A (plus the WFT-E2 II/WFT-E2 II A, announced today). Basic performance specifications, such as its 10fps maximum burst rate, 1/8000 top shutter speed, 1/300 standard flash sync, 55ms shutter lag and 80ms mirror blackout time - these also carry over to the EOS-1D Mark IV from the 2.5-year-old camera it replaces.

That leaves what Canon has added or changed:

Image sensor and ISO range Canon gave themselves a difficult task with the EOS-1D Mark IV: add over six million image pixels to the sensor while simultaneously increasing the extended ISO range by four stops.

Bumping up the image pixel count from 10.01 to 16.06 million, in a sensor that's about the same 1.3x crop size as before (at 27.9mm x 18.6mm, the Mark IV sensor is fractionally smaller than that of the EOS-1D Mark III), meant dropping the pixel pitch from 7.2µm to 5.7µm.

All other things being equal, larger pixels lead to better high ISO pictures than smaller pixels, so Canon's self-assigned mission to significantly boost image resolution and high ISO could well be viewed as an impossible one.

The Canon-supplied graphic below illustrates the ISO range and pixel size differences between the EOS-1D Mark III and EOS-1D Mark IV.

eto ata exciting features e... hehe



 HD video Now a standard digital SLR feature, the EOS-1D Mark IV's 1080p video mode features are on par with the 7D in almost all respects. This means manual and automatic exposure, three static AF modes that can be activated prior to and during video capture, both a built-in mic and a 3.5mm miniphone jack for an external stereo mic, audio sample rate of 48khz, built-in speaker, automatic audio gain with no manual override, H.264-compressed movie files with a .mov extension, in-camera video clip trimming and a 4GB clip length limit. Plus, a healthy selection of video and frame rate options:

    * 1080p: 1920 x 1080 pixels at 30fps (actually 29.97fps)
    * 1080p: 1920 x 1080 pixels at 25fps
    * 1080p: 1920 x 1080 pixels at 24fps (actually 23.976fps)
    * 720p: 1280 x 720 pixels at 60fps (actually 59.94fps)
    * 720p: 1280 x 720 pixels at 50fps
    * SD: 640 x 480 pixels at 60fps (actually 59.94fps)
    * SD: 640 x 480 pixels at 50fps

The resolution and frame rate selection screens are below. You'll see the menu on the left if the camera is set for NTSC. PAL brings up the menu on the right.



The EOS-1D Mark IV is expected to lead all other video-capable Canon digital SLRs in low light performance, and will certainly offer the highest sensitivity (the camera can capture stills or video at up to ISO 102,400). It will also be capable of depth of field effects that are shallower than the smaller-sensor 7D for a given field of view, but not as shallow as the 5D Mark II and it's larger full-frame sensor.

Canon hasn't incorporated the smart still/video mode switch and start/stop button of the 7D into the EOS-1D Mark IV. They have empowered the flash exposure lock (FEL) button, however, to optionally serve as the video quick start button. With the camera configured this way, pressing FEL, even when not in video mode, will begin the recording of a movie clip.

Wala pa rin full spec sheet.
I did not see any Dual Axis Electronic Level and the built-in Integrated Speedlite Transmitter in the specs of the 1DIV. Maybe it's just in the 7D and not the 1DIV.

Sir, mahirap yata na may built-in transmitter siya kasi wala siyang pop up flash :D... unless built in radio/infrared transmitter :D

hmm a little bit of OT here

bakit parang mas madaming magandang features pa ata ang 7D compare sa bagong 1Dm4. magkaiba kaya sila ng designer hehe

Possible. Its not uncommon na magkaiba ang design team ng mga camera lines.

This impression from john of DPP just killed my desire for a 1D series cam.
Well maybe 1DM5 in another 3 years or the rumored 3D.
For now my 5DMK2 and 7D will do.

"I've now had a Mark IV for about a week now. I agree with most of the above. I would put the Mark IV in the same results as the 7D and not as good as the 5D Mark II. Pretty disapponting, but I guess you can't have everything. Unlike the Mark III cameras I had the focus problem does seem to be resolved in the single shot burst. Still not convinced the AI servo does what I think it should do... All of the listed above cameras are not even in consideration when it comes to the the D3s as far as high ISO noise.. At least 2+ stops better than the best Canon camera I own.. Also the other disappointing thing about the out of camera jpegs is the softness of the results from the Mark IV. Very much like the original 1D Mark II out of camera softness (before the IIn fix)... I guess I am slightly disappointed with the Mark IV initially, but still need to try a few things. Right now the 5D Mark II and the 7D are better cameras from an output standpoint. Really surprising the 7D came out better. Not surprised the 5D Mark II did. I also don't see any great resolution with the 16 meg sensor---just looks soft even with the sharpening cranked up... 5D and 7D great prices for both cameras. The Mark IV way overpriced for what you get.."
