Canon EOS 7D sensor and processing

The Canon EOS 7D is able with a cast fresh 18 Megapixel CMOS sensor which generates 3:2 aspect arrangement images with a best admeasurement of 5184×3456 pixels; at 300 dpi, these can be reproduced at up to 17.3×11.5in, compared to 15.8×10.5in on the 50D or 13×8.6in with the 40D. Absolutely at the time of writing, alone the EOS 5D Mark II (and the beforehand EOS 1Ds Mark III) offered a college resolution in Canon’s ambit with 21.1 Megapixel sensors carrying 5616×3744 pixel images which can be reproduced up to 18.7×12.5in at 300 dpi.

The aloft aberration amid the sensors in the EOS 7D and the EOS 5D Mark II admitting are their concrete sizes: the EOS 5D Mark II employs a full-frame sensor barometer 36x24mm, while the EOS 7D uses a abate APS-C sensor barometer 22.3×14.9mm. As such the alone photo-sites on the EOS 7D are physically abate – absolutely it appearance the accomplished pixel anatomy of any Canon DSLR to date.

This understandably leads to apropos over added babble and bargain activating range. Canon provides some advance by application bigger gapless micro-lenses which it claims are added able than those on the EOS 50D, and you can see how they compare, forth with the EOS 5D Mark II and Nikon D300s in our Aerial ISO Babble after-effects pages.

The 7D’s JPEGs can be recorded at two lower resolutions (8 and 4.5 Megapixels) and with the best of Fine or Accustomed compression. RAW files are of advance offered, although almighty afresh in the best of three resolutions: either the abounding 18 Megapixels in RAW, 10.1 Megapixels in MRAW or 4.5 Megapixels in the SRAW; agenda these lower resolution RAW files were declared as SRAW1 and SRAW2 on beforehand models.

Cleverly the RAW and JPEG options can be set separately, acceptance you to accept any combination. So if recording both JPEG and RAW, you could accept RAW, MRAW or SRAW, accompanied by a JPEG at any of the three resolutions or two compression settings. The fresh RAW / JPEG button on the aerial larboard bend of the anatomy additionally allows you to bound about-face amid recording one or two accompanying files. Best affection Large Fine JPEGS about admeasurement 6.6MB each, while full-size RAW files admeasurement about 18MB each.

Like best Canon DSLRs, the EOS 7D employs 14-bit alternation to agenda conversions, and this 14-bit tonal detail is additionally recorded in the RAW images. See our After-effects pages for examples comparing the 7D’s JPEG and RAW output.

Like the EOS 50D, absorb abstracts can now be added to images, but you can now adapt this in-camera, rather than accepting to await on the EOS Utility software.

The acuteness runs amid 100 and 6400 ISO, or to an agnate of 12800 ISO (H) if ISO amplification is enabled in the Custom settings. This is one stop college than the Nikon D300s and matches the complete ambit of the EOS 50D, although this beforehand archetypal referred to both 6400 and 12800 ISO as continued settings. The EOS 5D Mark II offers a college 25600 ISO broadcast setting, and you can see how all four models analyze beyond their complete acuteness ranges in our Aerial ISO Babble results. Note: if Highlight Tone Protection is enabled, the 7D’s acuteness ambit is bargain to 200-6400 ISO.

On antecedent Canon DSLRs, the acuteness would stick at 400 ISO aback the ISO was set to Auto in Manual or Bulb; this charcoal the case for Bulb or beam exposures on the EOS 7D, although evidently Manual approach now works with Auto ISO in the aforementioned way as Program and the added acknowledgment modes.

Like the EOS 50D, two babble abridgement modes are accessible in the Custom Functions: Long Acknowledgment Babble Abridgement is activated to exposures best than one added and can be set to Auto, On or Off, while Aerial ISO Babble Abridgement is activated throughout the range, but added so at college sensitivities. Aerial ISO Babble Abridgement is accessible with four settings: Accepted (the default), Low, Strong or Disable. Agenda Strong NR will abate the best access during affiliated shooting.

Pressing the White Antithesis button allows you to accept from Auto, Daylight, Shade, Cloudy, Tungsten, White Fluorescent, Beam and Custom, followed by the advantage to manually access a colour temperature from 2500 to 10000 Kelvin. White Antithesis alteration and bracketing is additionally available.

Sharpness, Contrast, Saturation and Colour Tone are activated application a cardinal of Picture Styles: for colour photography, you accept the best of Standard, Portrait, Landscape, Neutral and Faithful, while a added Monochrome advantage offers four clarify and four toning effects. Contrast, Saturation and Colour Tone can be adapted in a fresh added ambit of +/-4, while Sharpness is offered from 0 to 7. While it’s accessible to abuse these presets or configure your own with the three custom modes in-camera,computer application supplied with EOS 7D lets you actualize and adapt attention Picture Styles to your complete requirements.

We acclimated the absence Accepted Picture Appearance for all our sample images, and begin it delivered adequately lively-looking JPEGs agnate in appearance to the EOS 5D Mark II, although not absolutely as crisp. They’re abundant punchier than the beforehand EOS 50D admitting which could arise absolutely aerial and aseptic at times.

Leveraging the EOS 7D’s 14-bit A-D about-face is the Highlight Tone Priority (HTP) option, affiliated from contempo models and still active abroad in one of the custom activity menus; it’s disabled by default. According to Canon, this improves the highlight detail by accretion the activating ambit from the accepted 18% blah to ablaze highlights. This advantage is alone accessible amid 200 and 6400 ISO and Canon warns babble could be added in adumbration areas. ‘D+’ icons announce Highlight Tone Priority in the viewfinder and on both the aerial and rear screens, so you should be in no agnosticism aback it’s enabled.

The EOS 7D additionally inherits the Auto Lighting Optimizer from contempo models, which adjusts the accuracy and adverse of images with aphotic areas (such as backlit portraits). The 7D offers the aforementioned four settings as the EOS 50D and 5D Mark II: Standard, Low, Strong and Disable. The Accepted ambience is consistently activated aback the 7D is set to Auto or the Scene presets, and is additionally activated by absence in PASM modes, although you can acclimatize it to one of the added three settings if preferred.

The settings and accomplishing may be the same, but Auto Lighting Optimizer on the 7D has now been answer from the base of the Custom area to its own arresting position on the added agenda page.

Canon EOS 7D Auto Lighting Optimiser: Off / Strong

Above you can see two examples of the aforementioned agreement taken with the Auto Lighting Optimizer disabled (above left) and with its Strong ambience (above right). In this accurate archetype which includes aphotic adumbration areas and complete highlights, we can see actual little affirmation of the Auto Lighting Optimiser in action. The caliginosity abide aphotic and the ablaze window highlights abide saturated. Lest you anticipate it’s the aforementioned image, we’ve included histograms of anniversary which acknowledge a actual slight abridgement in the adumbration aiguille on the adaptation with Strong Auto Lighting Optimization, but little aberration overall.

Following our action of application absence settings aback testing cameras, best of the aforementioned images you’ll see in this analysis were taken with Highlight Tone Priority off and the Active Lighting Optimizer set to Standard. Aback both can aftereffect in artificially college babble levels though, we ensured both were disabled for our Aerial ISO After-effects page.

The EOS 7D additionally inherits the Peripheral Illumination Alteration of the EOS 50D and 5D Mark II. This is optionally activated to JPEG images to abate the aftereffect of vignetting area the angel darkens appear the corners. The EOS 7D contains a database of 26 Canon lenses and allows you to access a added 14 models or bandy complete ones for added models if preferred. If the lens archetypal is recognised, the alteration will be activated by absence to JPEG images, although you can about-face the advantage off if preferred. Canon describes the consistent aftereffect as agnate to that offered on RAW images in contempo versions of its Agenda Photo Professional (DPP) software, although DPP itself can action added corrections.

Any lens for which DPP offers corrections can be entered into the 7D’s centralized database application the supplied EOS Utility. The best contempo adaptation includes alteration abstracts for the fresh EF-S 15-85mm and EF-S 18-135mm IS zooms. DPP additionally offers abstracts for anniversary lens adapted with a 1.4x or 2x Extender, although these will calculation as added entries in the 7D’s 40-model centralized database.

Since Peripheral Illumination Alteration is enabled by default, you’ll see the aftereffect of it on our JPEG sample images throughout this analysis taken with the EF 24-105mm f4.0L IS lens.

In our tests, it accepted actual able at abbreviation the aftereffect of vignetting, although in acute cases with assertive lenses there can still some concealment in the acute corners.

It charcoal a advance over the versions afterwards though, but bethink any agenda brightening will aftereffect in potentially greater arresting babble in the activated areas – abnormally if the ISO was already aerial on the original.

Note clashing the Nikon D300s, the EOS 7D does not automatically actual coloured fringing in-camera. Instead you’ll charge to use the supplied DPP software.

Canon EOS 7D drive modes and alien control

The Canon EOS 7D offers two affiliated cutting modes: Low which shoots at 3fps and Aerial which shoots at 8fps. The closing is 1.7fps faster than the EOS 50D and over alert as quick as the 5D Mark II; absolutely it approaches the 10fps top acceleration of Canon’s pro sports DSLR, the EOS 1D Mark IV. It additionally assuredly gives the Canon an bend over its battling from Nikon. The D300s offers 7fps as standard, although this is boostable to 8fps with the alternative array anchor (when adapted with the appropriate batteries). The EOS 7D’s acceleration isn’t accelerated by its array grip, but by boasting 8fps with no alternative accessories, it numerically has the advantage.

Of advance these quoted abstracts are all theoretical, so to see how the EOS 7D absolutely performs in convenance we adapted it with a formatted Lexar Professional UDMA 16GB 300x Compact Beam agenda and set the camera to Affiliated High. In Large Fine JPEG mode, the 7D rattled-off no beneath than 157 JPEGs in 20 abnormal and seemed blessed to abide while amplitude remained; this corresponded to a amount of 7.85fps.

Set to RAW mode, the 7D managed 20 frames in three abnormal afore slowing, agnate to a amount of 6.6fps. Autograph to the agenda was actual fast, with the action completed afterwards alone a few seconds.

The RAW cutting amount we abstinent may accept been a little slower than the quoted top speed, but the JPEG amount was alone a atom beneath 8fps in practice. In comparison, we abstinent the D300s cutting JPEGs at 6.3fps and RAW files at aloof beneath 6fps. It’s important to agenda this RAW acceleration on the D300s was with 12-bit data, and switching it to 14-bit alone the acceleration to aloof 2.35fps. In contrast, the 7D alone annal its RAW files in 14-bit.

So aback comparing JPEGs or 14-bit RAW data, the EOS 7D calmly out-paced the D300s, and this is alike added absorbing aback you accede it’s alive 50% added abstracts with every frame.

To be fair, the 6.3fps JPEG amount we abstinent from the D300s is still actual fast and should be added than acceptable for best applications, but the EOS 7D is quicker still and becomes the best advantage for anyone ambitious complete top anatomy ante afterwards advance in a pro sports body.

Note during our tests, Canon appear a account advising admonishing the EOS 7D could ache from ghosting during affiliated shooting. We didn’t apprehension this on any of our affiliated sample images and you can see several examples in our Gallery and HD Video bout – although they were taken beneath ablaze lighting altitude at almost low ISOs. Canon has about aback appear a firmware amend which it claims fixes the affair (version 1.1.0 appear during aboriginal November 2009).

In agreement of the self-timer, the EOS 7D gives you the best of 10 or 2 added countdowns, although it doesn’t allotment the added custom timers of contempo customer EOS DSLRs which can booty assorted shots as insurance. A mirror alcove advantage is about accessible in the custom menu, which applies to either accustomed or self-timed shots. Clashing the Nikon D300s, there’s no congenital Intervalometer, but in its favour, the 7D can accomplish this and abundant added aback affiliated to a computer with supplied software.

In a affection which aboriginal fabricated its admission on the EOS 40D, the 7D can be remote-controlled by a PC or Mac application the supplied EOS Utility. Images can be recorded to your computer’s adamantine disk, the centralized anamnesis agenda or both, and there’s Intervalometer accessories for programmed shoots. The camera can be affiliated to your computer either anon with the supplied USB cable, or via the alternative WFT-E5(A) wireless transmitter; the closing allows active or wireless Ethernet connections, forth with ascendancy via a web-based interface for alien ascendancy which could potentially be on the added ancillary of the world.

Up to ten EOS 7D’s able with WFT-E5(A)s can additionally be triggered by the aforementioned computer. To acquisition out added about the wireless transmitter capabilities, see our WFT-E3(A) review; this archetypal may be advised for the beforehand EOS 40D and 50D bodies, but is physically and functionally actual agnate to the WFT-E5(A).

The EOS Utility lets you alien ascendancy and acclimatize appealing abundant any ambience that doesn’t absorb the concrete about-face of a punch or flick of a switch. So you can’t change the acknowledgment approach from, say, Breach to Bang Priority application the software, but you can acclimatize the breach or bang value, the angel quality, white balance, metering or acuteness for example. Impressively thecomputer application additionally lets you see the Live Appearance on your computer adviser and alike lets you manually or autofocus the lens with a abstract appearance for assistance. We accept a affirmation of this in our EOS 7D video tour.

New to adaptation 2.7.0.2 which comes supplied with the EOS 7D is the advantage to acclimatize the beam settings and automatically popup the centralized beam if desired, although you’ll charge to advance it aback bottomward afresh yourself. You’ll additionally see a Peripheral Illumination Alteration area which lets you accept which 40 lenses from the complete Canon EF archive should abide the 7D’s centralized database.

Software-based alien ascendancy is a admirable affection to accept and if you accept a laptop handy, it could alike annihilate the charge for assertive photographers to advance in a cable release. In actuality the alone downside we could acquisition was the disability for the USB anchorage to ability the camera itself, thereby authoritative an AC adapter binding for austere abandoned photography.
