Expert Review of Canon EOS 1D Mark IV DSLR Black
There is a reason as to why Canon is the Numero Uno camera manufacturer in the world, for it builds on the successes of the preceding models and adds the vital features that ensure the success of the next product. Added to that is the Halo effect associated with Canon which is simply a class apart, like Apple in phones. An example of how Canon builds on the successes of its past products will be given in the review of our next device, the Canon EOS 1D Mark IV SLR, which happens to be a direct replacement of the previously breathtaking Canon 1D Mark III model. As usual, it only supplements the good features what its predecessor camera had and improves upon the number of areas that lacked in the technology previously. Perhaps the most significant ones of these are the use of new 16.1MP CMOS sensor and dual DIGIC 4 image processor respectively. These together allow a real increase in terms of image resolution and are a huge step up in the ISO sensitivity range of the camera whilst maintaining the predecessor’s 10fps rate. Other successful gains include a highly upgraded AF system, an advanced high-resolution LCD display monitor, which is provided with enhanced resistance for reflection or glare. Alongside that, is this year’s must attain feature, which is the HD capability. One must take note that other changes for the device very well include a high support for the UDMA CompactFlash cards, the Peripheral Illumination Correction, a new array of Auto Lightning Optimizer technology from Canon and more.
Design and Build Quality
While talking about the design and build quality, it comes to light that Canon EOS 1D Mark IV features a very rocky professional type magnesium alloy body which in itself contains almost 76 gaskets and seals for weather and dust resistance purposes over the inner body consisting of magnesium alloy. Without the lens attached, the device is like a giant and weighs well over 1kg at 1,180grams wherein, much credit of this weight gain goes to the new LCD display. When you attach a battery and a Compact Flash card, the weight rises to 1,400, which really may hinder the handling of the device quite certainly. That been said, when we talk about the ergonomics of the device it seems that from the outside Canon EOS 1D Mark IV is simply the very definition of how a professional camera should be: solid and rugged. If you doubt that, the 3-pound weight should be enough to elaborate on that, and that too, without a lens mount. Once in hand, it seems easy to operate, with a good amount of attention been thrown towards the fingers and thumbs so that the weight does not become a big hindrance, they have to be in rest so that you can operate the device effortlessly. Yes, the camera seems slightly less comfortable to operate when you put it in portrait orientation, as your thumb feels digging into the sides, the sort of neglected AF-on the button. But still, it is a minor complaint as it is quite clear that with a camera like this, one has to be rather foolish to operate it with one hand.
Focus and Face Detection
Let us now talk about the AF system of Canon EOS 1D Mark IV, it has been given a definite significant overhaul. Well, the total number of focusing points are left untouched and remained stagnant at 45, what has changed though is the number of cross type points, which are now two fold. The number of cross type points on Canon EOS 1D Mark III was 19, it is no less than 39 on Canon EOS Mark IV, so out of the 45 total AF points, 39 are high precision (i.e., f/2.8 compatible) cross type points. In addition to that, while the 26 remaining points on the successor were available as assist points only and hence were not user selectable, in this case, all of the 45 points are well in control of the user. The Canon EOS 1D Mark IV’s AF modes make the inclusion of both one shot system and servo, with the successor now having a new designation called AI Servo II AF, obviously as a result of changed algorithms. No longer, will there be a delay between subject starting to move and the AI Servo beginning its trajectory and predicting the position of focus. If an obstacle passes between the subject and the camera, or the AF point happens to slip off the subject, our camera will continue to track down much because of the last calculated subject trajectory. If the photographer decides to leave the AF point off the subject for a big period of time, the camera will start focusing towards a new position, but this will be done more gradually than previously, rather than just suddenly snapping the focus right at the background.
Lens and Image Stabilization
Much like its predecessor, the Canon 1D Mark IV accepts Canon’s EF, TS-E or MP-E lenses, but simply not the EF-S lenses, which are designed only for smaller APS-C sensor format. There is only a significant list in which, all the 39 points of AF can work highly precisely, these lens mounts are as such:
· EF 17-40mm f/4L
· EF 24-105mm f/4L I
· EF 70-200mm f/2.8L IS w/ Extender EF 1.4x II
· EF 200mm f/2L IS + Extender EF 2x II
· EF 300mm f/2.8L IS + Extender EF 1.4x II
· EF 400mm f/2.8L IS + Extender EF 1.4x II
Screen and Menus
Beneath the eyepiece of the viewfinder, we get hold of Canon 1D Mark IV that provides 3-inch LCD approximately carrying 920k dots of resolution and is equivalent to VGA (640 X 480) pixel array having three dots per color. This is a significant step up in the case of resolution from 230k dots display on Canon EOS 1D mark III and hence, the screen becomes much better for judging the accuracy of focus. The panel on the device is what Canon calls in as Clear View II LCD type wherein, it actually is the same model that appeared rightly on the cover glass and LCD surface of the device. The cover glass for this device has also been given an upgrade and now, is very highly scratch resistant tempered glass rather than the earlier acrylic plate which was used in Canon EOS 1D Mark III.
Our reviewed device draws all its power from the LP-E4 Li-Ion rechargeable battery, pretty much the same that was earlier seen in the previous model. It is however, a little annoying to say that the battery life rated on this device is much lower than on Canon EOS 1D Mark III, and that will account in the sensor resolution being increased, and the attendant increase in the processing that it brings. Where you can say that Canon EOS Mark III is rated to yield 2,200 shots on a single charge and Canon EOS 1D Mark IV is rated to bring in 1,500 shots for a single charge in the same conditions.
Yet another area accounting for significant change is Canon EOS-1D Mark IV, which has the new HD video capture mode. The functionality of this device is hugely similar to that of Canon EOS 7D DSLR, and hence provides for recording of movie clips right up to 4gigabytes in size, these are saved using AVC/ H.264 compression in a .MOV container. The resolution and frame rate options of the device include 1,920 x 1088 pixels (23.976, 25, or 29.97fps), 1,280 x 720 pixels (59.94 or 50fps), or 640 x 480 pixels (59.94 or 50fps). The numerous frame rates match various broadcast television formats etc., removing the need to transcode to the intended output frame rate after capture, and the available frame rates will depend on whether the camera is set to NTSC or PAL mode.
In the huge body comes a newly designed image sensor that builds on to a dual DIGIC 4 image processor, which together brings about improvements in ample areas. Approximately equivalent in size to a frame of an APS-H film, Canon EOS 1D Mark IV’s RGB filtered Canon CMOS image sensor has within itself a very effective resolution measuring 16.1megapixels and a total resolution adding up to 17megapixels. By default, the pictures are clicked in 3:2 aspect ratio, and brings out images measuring a maximum of 4,896 x 3,264 pixels in JPEG as well as 14-bit CR2 RAW formats. In the lower-resolution options, 4,320 X 2,880 pixels (JPEG only, 3,672 X 2,448 pixels (M-Raw only), 3552 x 2,368 pixels (JPEG only), and 2,448 x 1,632 pixels (JPEG or S-Raw) options are included.
