The bulk of these are really designed to improve focus tracking during continuous shooting, and, much like Nikon's AF system, you have to think very carefully about matching the AF choice with the shooting situation or you can end up with surprising results.
#CANON 7D USED EBAY FULL#
Zone AF is similar to AF point expansion in that it allows you to define clumps of points in the center, top, bottom, or sides of the full AF area, but in contrast to expansion, where you still choose the primary focus point and it only uses the other points if the subject moves, the camera automatically chooses points from within the defined zone.
AF point expansion uses the three or four (depending upon location) points surrounding the chosen one. Spot AF is a subarea of the traditional single-point AF, and for both of these you can choose from any of the 19 AF points. Of course, there's the veteran full automatic AF selection. ISO 50 (expanded)/100- ISO 6,400/25,600(expanded)Īll cross-type center cross-type to f2.8Ĭanon went from very few AF options to a gazillion in one model. (Since I didn't get to take the camera to Antarctica to test its weather sealing, cold resistance, and ruggedness, I'd follow Ole Jørgen Lioden's testing on that, if you're interested.) It's also slightly more comfortable than the D300s' because of the larger eyecup. The new viewfinder is great, comparable with that of the D300s: big and bright, with an optional overlay grid. One of the heavier single-grip dSLRs available, there are no radical design departures in the 7D but there are tons of subtle, and a few conspicuous, interface changes that greatly enhance the fluidity of the camera's operation. It's a lot more expensive and a bit shorter, but I think it's a significantly better lens. I'm not really fond of it, though, and if you're looking for a starter kit, I'd recommend the newer 15-85mm f3.6-5.6 IS USM lens (28.8-136mm equivalent) instead. In addition to a body-only version, Canon sells the 7D in a kit with the 28-135mm f3.5-5.6 IS lens (44.8-216mm equivalent).
#CANON 7D USED EBAY 1080P#
But with entirely new AF and metering systems, a new high-resolution eight-channel readout sensor coupled with dual Digic 4 image processors and a new 100 percent coverage viewfinder, plus 1080p video capture, the 7D looks like an aggressive attempt to make a comeback. Canon basically ceded the entry-level pro performance market to Nikon in 2005 with the arrival of the D200 since then, Canon's 30D, 40D, and 50D have taken the slower but less-expensive road, with a relatively stagnant AF system, which Nikon leapfrogged.
