Canon 1D Mark IV Compact Digital Camera 16.1 Megapixels Black

Product Information

CompactFlash and/or SDHC (SD High-Capacity up to 32GB) memory cards can be used individually or simultaneously - recording the same or different image format to each. Canon's EOS Integrated Cleaning System employs a piezoelectric, vibratory cleaning method when the power is switched on and off, as a primary part of the overall strategy. To avoid missing the action when first starting up, the Canon 1D Mark IV aborts its power-on cleaning cycle as soon as the user touches the shutter button. This insures that you won't miss a critical shot due to sensor cleaning. It's also possible to trigger the cleaning system to operate manually -- either as well as, or instead of, the automatic startup / shutdown operation. Take complete creative control of your images with PIXMA and imagePROGRAF PRO professional photo printers. There are many ways to focus calibrate a lens to the 1D Mark III, but they all have the same goal - find the sharpest setting for the combo.

To take full advantage of the 14-bit file format, you need to shoot in RAW and make all post-processing adjustments before creating a JPG file (8 bit). Each pixel's amplifier has been enlarged; this has helped to reduce dark current noise in the EOS-1D Mark III by a factor of 1.33X, relative to the EOS-1D Mark II/EOS-1D Mark II N. When Nikon announced the launch of the D3S, it raised the bar for noise control and sensitivity. Canon has matched the D3S’s maximum sensitivity setting of ISO 102,400 for stills and video capture with the EOS-1D Mark IV, but the results are extremely noisy. Pan to your desired in-focus points using the mouse and adjust the lens focus using the coarse and fine control buttons available - with no camera movement. The 1D III makes my 1Ds II (from the 1D Mark II and 1D Mark II N era) feel very much like it is due for an update.The new camera has the same magnesium-alloy construction and 76 dust and waterproof seals as the camera it replaces. It feels very solid and built to last. However, by my calculations the quoted 300,000-cycle shutter durability only equates to around 8 hours and 20 minutes’ use at 10fps. While this would be an exhausting single shoot, it doesn’t really seem that long for the expected life of a key component of a professional sports photographer’s camera. As an APS-H-format camera, the EOS-1D Mark IV has a smaller viewfinder than the full-frame EOS-1Ds Mark III. However, it offers an approximately 100% field of view with 0.76x magnification. This is interesting as the APS-C-format EOS 7D also offers a 100% field of view, but it has 1x magnification, which means its viewfinder is slightly larger. Nevertheless, the EOS-1D Mark IV’s viewfinder is very clear and bright, and it is easy to focus manually when viewing the scene through it. Clearly, Canon has learned a few lessons in the intervening period. Its recent DSLRs have indicated a change in its ethos, as new systems and technology have been introduced to make the company’s cameras even more competitive. For the latest camera in the EOS-1D series, the EOS-1D Mark IV, this has meant a completely new AF system, a 16.1-million-pixel APS-H-format sensor and a maximum sensitivity setting equivalent to ISO 102,400, which matches that of Nikon’s D3S. It could be the riposte that Canon has been searching for. Features When the noise reduction is turned off the level of noise is off the scale of our testing regime, so we are unable to report meaningful figures at ISO 51,200 and 102,400. Even in the raw files, detail resolution is heavily compromised at these highest expansion settings and I would avoid using the ISO 102,400 option.

The Canon EOS 30D is at a disadvantage in this comparison as its LCD display only shows about 98% of the final image. Canon's 1-Series bodies have consistently been a no-compromise solution featuring top-of-the-line performance in all aspects. There's a downside, of course - that additional highlight dynamic range comes at the expense of greater shadow noise. It's also worth bearing in mind that not all RAW converters will implement the correct tone curve, so you risk all your images appearing underexposed until you've worked out your own 'push-process' workflow. pixel (690,000 dot), 3.0" color TFT liquid-crystal monitor with approx. 100% coverage (for JPEG images) Personal Functions consolidated with Custom Functions, resulting in 57 Custom Functions in 4 groupsYes, the 1D III has Canon's latest self-cleaning sensor, but based on my experience, you are going to need this manual At more routine sensitivity settings, the EOS-1D Mark IV is capable of recording a high level of detail. Banding noise in the EOS-1D Mark III has been lowered by the equivalent of one stop, also relative to the EOS-1D Mark II/EOS-1D Mark II N. But this method could be problematic - if the person was leaning too far forward or arms got in the way, the athlete's eyes would not be in focus. Accessories: Two new accessories were announced with the 1D Mark III: the WFT-E2A Wireless Transmitter for WiFi, Ethernet, hard drive, and GPS compatibility; and the 580EX II, with several new features, including weather sealing around the hot shoe.
