![]() ![]() When using a long telephoto lens on a bright, hot sunny day with an at-least-slightly backlit subject, AI Servo focus accuracy drops to very low. The 1D III AI Servo AF accuracey problem: The top-most focus point was used and placed on the girl's face - arms should have had no influence on the result, distance does not seem to matter (this shot is one of the 30-40% in-focus minority). ![]() This is the same set of circumstance Rob Galbraith discusses in his intro-shattering focus problem report and demonstrated below. What is especially bad is the 60-70% AI Servo OOPF rate I get in a narrow set of circumstances. No DSLR is perfect in this regard - and I didn't expect perfection from the 1D III.īut, with a new flagship camera sporting a dedicated AF processing unit, I expected improved performance in this area. The shots the 1D III is capable of getting are impressive - I just think an extra 10% or so should be right on. The rate is consistent - I am positive it is not all me. Some of these shots could be kept - they are just not precisely in focus.Ī percentage of the OOPF shots are certainly self-caused (try tracking a bouncing rider's head on a galloping horse as they close in at near the 300mm f/2.8 IS's minimum focus distance),īut the 1D III's AI Servo AF seems to simply get lost for short sets (3-5) during the burst. (which has the same AF system as the 1D II and 1D II N - but half the frame rate). Though not bad, it is not much (if any) better than from my Canon EOS-1Ds Mark II What helps out my keeper selection process a small amount is the 20% or so OOPF (Out of Perfect Focus) rate I get from the extremely fast-focusing AI Servo AF mode. The manual states that high ISO speeds greatly reduce the number of frames capturable in a burst, but the 1D3 still delivered a RAW 26 frame continous burst at ISO 3200.Ī Custom Function setting can be set to explicitly reduce the frame rate as desired. Or a slow shutter speed is selected (fast shutter speeds are generally used for catching action). These numbers change slightly or even dramatically based on the camera settings -Įspecially if the aperture must be stopped down significantly (the aperture opens between each shot so AF can continue to work) These 10 fps bursts deliver a huge number of images - generally 10 per second and generally around 30 in a sequence if I hold the shutter release down that long. I suppose I could just keep all of them - but I usually am looking for the selects only. What I don't love as much is the difficulty I am presented with when selecting keepers from my take-home. Ĭanon 1D Mark III Soft Mode (70 db shots with four normal 77 dB single shots included) Listen to this and the other drive modes including the new "Silent Mode" (these are MP3 files). The 1D III's 10fps burst machine-gun-like sound is awesome itself. Ĭanon 1D Mark III Digital SLR 10fps video (an animated jpg). To get a better feel for 10 fps performance, watch a. I'm not bad at capturing a moment with a single shot (it is the primary way I shoot on my 1Ds II), but 10 fps will usually get me the best shots. This frame of a tiny grass shrimp positioned so nicely in a Great Egret's open mouth came from the middle of a 10 fps series of shots. The Canon EOS-1D Mark III stands alone in its ability is able to capture an action sequence. ![]() Of course, with a frame rate about 20% faster than its EOS 1D Mark II N predecessor, 3s is negligible.īut, the models start showing their differences in the shutter lag and viewfinder/mirror blackout time specs - the difference between 55ms and 100ms is quite noticeable. Īll current Canon EOS Digital SLRs have near-instant-on capability - the difference between. Here is how some recent Canon DSLRs compare. RAW images per second for 3 seconds in normal shooting situations with a reasonably fast memory card installed. What it delivers is 10 frames of 14-bit, 10.1 mp, 1.3x, When you must get the shot - this camera delivers. The Canon 1D III is all about speed - quickly capturing great shots of fast-moving subjects in even the toughest circumstances. I have been extremely happy with my 1Ds II - it is an awesome camera, so generating this feeling is not an easy accomplishment.īut there are just so many new and improved features on the 1D III. 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. Otherwise, the 1D III is better in practically all regards. Redesigned from the ground up, the 1D III has so many new and improved features that it is hard to know where to start.Īctually, it is easier to start with the only feature that is not best in class - The 1D Mark III does not have the 16.6mp resolution full frame sensor of the With the Canon EOS-1D Mark III, Canon takes us another big step forward in digital SLR technology. Note: The Canon EOS-1D Mark III has been replaced by the Canon EOS-1D Mark IV. ![]()
