ADVERTISE

The Canon EOS 7D offers the aforementioned four metering modes as contempo models: multi-zone TTL Evaluative, Partial (9.4% of v/f area), Atom (2.3% of v/f area) and Center-weighted; back spot-metering is selected, the viewfinder LCD arrangement displays a amphitheater advertence the area.

Before you anticipate there’s no aloft changes added than the atom amphitheater though, the EOS 7D absolutely employs a cast fresh iFCL metering arrangement with 63 zones. FCL stands for focus, colour and luminance, all of which are now advised by the metering system. The sensor additionally has bifold layers, one acute to red and blooming ablaze and the added acute to dejected and blooming light.

As always, we acclimated Evaluative metering for all out after-effects and arcade shots and didn’t acquisition any occasions (beyond cutting analysis charts) area we bare to administer any compensation. During our tests it accepted added consistently reliable than the beforehand Canon metering arrangement (although to be fair we never begin it that bad), and afresh brings yet addition aspect of the 7D afterpiece to Nikon’s technology – afterwards all its accomplished battling has continued active both ambit and colour advice on its able metering system.

In agreement of exposures, the EOS 7D is no altered from the EOS 50D: there’s the accepted bang acceleration ambit from 1/8000 to 30 abnormal additional a Bulb option, while the fastest beam accompany acceleration is 1/250. The EOS 7D’s bang block is about rated 50% best than the EOS 50D: it’s rated for 150,000 shots, which is the aforementioned as the Nikon D300s.

Sadly admitting all the addition and enhancements, Canon’s bootless to decidedly advance the basal bracketing options of the EOS 7D from beforehand models. As such you aloof get the bog-standard three frames, admitting now at up to 3EV afar in 0.3EV increments, which will assuredly be black to HDR fans. In abrupt contrast, the Nikon D300s boasts acknowledgment bracketing with up to nine frames at increments of 0.3, 0.5 or 1EV apart. It’s acutely one allotment of the Nikon arrangement Canon wasn’t aggressive by.

Canon EOS 7D anti-dust

As far as we understand, the EOS 7D offers the aforementioned three techniques to action dust as the EOS 50D and 5D Mark II: anti-static coatings to abate it afraid in the aboriginal place, a cavernous clarify which tries to shake-free the added adamant particles, and a software-based band-aid which maps the position of any annoying marks and appends them to images for automated abatement after application the supplied Digital Photo Professional software.

Following our accepted DSLR torture-test we larboard our 7D face-up after a lens, central and alfresco for ten account each; we can’t apperceive how abundant dust entered the anatomy during this time, nor alike how abundant was present to alpha with, but we apperceive such a action would aftereffect in dust actuality a botheration for best models. We again adapted the 7D’s Dust Delete Data and powered the camera on and off alert to beat the filter.

We again took a alternation of photos at every breach ambience of a credible white credible at abutting ambit with the EF 24-105mm IS lens zoomed-into 50mm and manually focused to infinity. Dust marks commonly become best credible at the aboriginal apertures (eg f16 and f22), but it’s additionally important to analysis at added accepted apertures.

Canon EOS 7D dust archetype at f22 / f22 with Auto Levels

With the 7D set to f22 we spotted a brace of actual aside marks, although with the best accessible circumscribed aloft left, best would accede it’s hardly bulging – absolutely we’ve had to administer Auto Levels to acknowledge its area added acutely in the angel aloft right. As the breach was opened, these marks bound grew broadcast and about abolished at f16 or larger.

The supplied Digital Photo Professionalcomputer application articular that Dust Delete Data was present on both JPEG and RAW files, and acclimated it to annihilate several marks, although interestingly not the one pictured above. So alike admitting the 7D’s anti-dust arrangement (like best DSLRs) wasn’t 100% infallible, dust could hardly be declared as an affair during our tests – a acceptable aftereffect for the 7D.
