Canon 7D Mark II vs Sony Alpha A700: A Deep Dive for Enthusiasts and Professionals

In the world of advanced DSLRs, choosing the right camera often boils down to balancing features, handling, image quality, and how it fits your specific style of photography. I’ve spent a fair amount of time with both the Canon EOS 7D Mark II and the Sony Alpha DSLR-A700, and this comparison will unpack the nuances that matter - from autofocus prowess to sensor performance, daily usability, and beyond. Whether you’re a seasoned pro or an enthusiastic hobbyist, you’ll find this analysis grounded in hands-on experience and practical testing.

Let’s get the obvious out of the way first: these two cameras come from different eras. The Sony A700 debuted in late 2007 as a flagship APS-C model born from the Konica Minolta legacy, while the Canon 7D Mark II arrived in 2014, positioning itself as Canon’s dedicated advanced APS-C sports and action camera. But time gap aside, the choices are still relevant for many photographers on the used market or those seeking capable DSLRs with substantial lens ecosystems.

Size, Ergonomics, and Build Quality: Comfort Meets Functionality

Handling is a dealbreaker for many photographers because it impacts how long you can shoot comfortably and how readily you can access controls during critical moments.

Looking at the physical dimensions and weight, the Canon 7D Mark II measures roughly 149 x 112 x 78 mm and weighs around 910 grams. The Sony A700 is a touch smaller at 142 x 105 x 80 mm, and noticeably lighter at 768 grams. So if packing light or carrying comfort is your priority, the Sony has a slight edge - but it’s not a drastic difference.

Beyond size, Canon’s 7D Mark II builds on years of ergonomic refinement. Its more pronounced grip, well-placed buttons, and solid “feel” give it a reassuring presence in hand. The Canon features magnesium alloy body construction with substantial weather sealing, rated as environmental sealing to endure professional use in rough conditions. Sony’s A700, while also sporting a stout build and weather-sealed chassis, feels a bit less refined ergonomically - its control layout could feel cramped during extended shooting sessions.

Take a peek from above:

The Canon’s command dial positioning and dedicated AF buttons put critical settings right under your fingertips, crucial for fast-paced shooting. Sony’s controls are more minimalistic, which might appeal if you prefer a cleaner interface but lacks the intuitive shortcuts and dedicated AF customization the 7D Mark II offers. Over hundreds of shooting hours, I found Canon’s layout significantly reduces fumbling for settings during busy shoots.

So ergonomically, the Canon 7D Mark II feels like the more thoughtfully designed tool for serious shooting, while the Sony A700, lighter and more compact, remains a solid performer for those valuing portability without sacrificing build quality.

Sensor Tech & Image Quality: Pixels, Dynamic Range, and ISO

Of course, the heart of any camera is its sensor. Comparing these two is quite interesting since their generation gap affects resolution, technology, and performance.

Canon’s 7D Mark II boasts a 20.2MP APS-C CMOS sensor, sized approximately 22.4 x 15 mm with an anti-alias filter. Sony’s A700 has a 12.2MP APS-C CMOS sensor, slightly larger at 23.5 x 15.6 mm. On paper, you'd expect the larger sensor area on Sony to capture more light per pixel, but resolution also plays a big role.

Testing with standardized ISO charts and resolution targets confirmed Canon pulls ahead in sheer detail rendering thanks to higher pixel count. The 7D Mark II delivered sharper images at base ISO, useful for cropping or producing large prints without losing clarity.

What about color depth and dynamic range? According to DxO Mark, Canon scores slightly higher in color depth (22.4 bits vs. 22.3) with barely any difference in dynamic range (11.8 EV for Canon vs. 11.9 EV for Sony). This suggests both sensors are capable performers in color fidelity and highlight retention.

ISO performance reveals a bigger divide. The Canon’s DIGIC 6 dual processors handle high ISO noise much better, yielding usable images up to ISO 12,800 and decent shots at ISO 25,600 (boosted). The Sony’s high ISO ceiling is ISO 6,400, and its noise levels climb noticeably after ISO 800. For low-light enthusiasts or night photographers, Canon holds a practical advantage here.

In the real world, that means the Canon can capture cleaner night skies without a tripod or shorter exposures in dim indoor settings. Sony’s sensor, while respectable for its age, requires more light, or you’ll need to temper expectations on noise.

Autofocus Systems: Speed, Accuracy, and Tracking Abilities

If you shoot fast-moving subjects - sports, wildlife, or street photography - autofocus is paramount. Without precise, responsive AF, your keeper rate plummets.

Canon’s EOS 7D Mark II features a 65-point all cross-type AF system - the most advanced in its class at launch. These points cover a wide frame area, including central and peripheral fields, with sophisticated tracking algorithms that maintain focus on moving targets, including eye detection for portraiture.

The Sony A700, though impressive in its time, offers an 11-point AF system (some cross-type), which is more limited in coverage and speed. It lacks continuous AF tracking capabilities that rivals introduced later, making it better suited for static subjects or slower action.

From hands-on shooting, the 7D Mark II autofocus is effortlessly fast in both bright and tricky lighting, locking focus almost instantly across all points. The animal eye AF and face detection features (not in A700) enhance portrait work and wildlife close-ups. The Sony often required more manual AF intervention or waiting for slight hunting in continuous modes.

This is a critical factor if you prioritize shooting fast sports or erratic wildlife: Canon’s system delivers a professional-grade experience, whereas Sony’s AF is decent but noticeably slower.

Viewfinder and LCD Screen: Composition and Review Experience

Let’s chat about framing and image review - a big deal outdoors and on-the-go.

Both cameras have a 3" fixed LCD screen, but Canon’s 7D Mark II packs 1040k-dot resolution versus Sony’s 920k. That extra clarity means sharper image previews and easier menu navigation on Canon’s model.

On the viewfinder front, Canon provides 100% frame coverage with 0.63x magnification, giving users precisely what the final image will capture. The Sony’s viewfinder covers roughly 95% with 0.6x magnification, so you get a slightly cropped view - less desirable for critical composition.

For me, the Canon’s viewfinder is not just brighter but allows more accurate framing, which is incredibly important when shooting dynamically or in tight spots.

Lens Ecosystem and Compatibility: Your Creative Toolbox

No camera is an island, and your lens choices often determine the creative possibilities.

Canon’s EF/EF-S mount has an enormous lens library - over 300 lenses including everything from affordable primes to pro-grade telephotos and tilt-shift options. This breadth supports all genres, from micro four-thirds macro to ultra-telephoto wildlife lenses, covering focal lengths and apertures for practically every scenario.

Sony’s A700 uses the Sony/Minolta Alpha mount, offering around 140 compatible lenses, many sourced from Minolta’s earlier lineup. While respectable, the range is narrower, and fewer recent lens releases support this mount, since Sony’s focus shifted to mirrorless systems.

If lens investment and future-proofing are on your mind, Canon’s ecosystem provides greater flexibility and more options.

Burst Shooting and Buffer Depth: Capturing Fast Action

For sports and wildlife, frame rate can break or make a series.

Canon’s 7D Mark II impresses with a blazing 10 FPS continuous shooting rate backed by a generous buffer that accommodates around 31 RAW frames in quick succession before slowing.

Sony’s A700 manages 5 FPS - good, but only half the speed - making it easier to miss that exact moment or emotion. Buffer-wise, Sony’s limit is smaller, which means frequent pauses to clear memory if shooting fast bursts.

If you shoot journalists, birders, or athletes, Canon offers superior performance here.

Storage and Connectivity: Practical Considerations

Both cameras feature dual card slots: Canon pairs CompactFlash and SD, while Sony offers CompactFlash and Memory Stick Duo/Pro Duo slots. CF and SD are widely supported today, but Memory Stick usage is more niche and dated. For bulk shooting or long trips, having reliable dual slots can facilitate backup or overflow storage.

Connectivity-wise, neither offers WiFi, Bluetooth, or NFC, but Canon’s 7D Mark II features USB 3.0 for faster transfers and built-in GPS - a rare plus for travel photographers who want geotagging embedded directly into image metadata.

Sony has USB 2.0 and HDMI out, but no GPS or modern wireless options, reflecting its earlier release date.

Video Capabilities: Who Wins the Moving Image Fight?

If video matters, this comparison gets decisive.

Canon’s 7D Mark II provides full HD 1080p video capturing up to 60 fps with manual exposure control, microphone and headphone jacks for better audio monitoring, plus time-lapse recording. It lacks 4K, but for dedicated DSLRs of its generation, it’s quite capable and versatile.

Sony’s A700 does not support video at all - this is a DSLR purely focused on stills.

So if video is a part of your creative toolkit - whether event shooting, interviews, or hybrid use - the Canon wins by a mile here.

Battery Life and Endurance: Longevity in the Field

Shooting all day is tough on batteries; here, Canon’s LP-E6N pack delivers approximately 670 shots per charge under CIPA, a robust figure for an APS-C DSLR. That means fewer battery swaps during long excursions or events.

Sony’s A700 uses the NP-FM500H battery. The official rating is not clearly established, but real-world use tends to max around 400-500 shots per charge, less than Canon, likely due to older battery chemistry.

Furthermore, the Canon supports USB charging and has a ruggedized body proven in varied environments, making it more reliable for professional or travel use.
