Why I Stuck with Sony Over Canon Mirrorless Cameras: A Professional Photographer's Journey

Why I Still Shoot Sony After Seriously Testing Canon

This is not a post I expected to write. I've been shooting Sony for years — starting with the A7 III, moving to the A7 IV, and now working with the A7V — and I had gotten comfortable enough with the system that I hadn't seriously questioned the choice in a long time.

Then Canon's RF system started generating real buzz in photography circles. The R5 and R6 got reviews that were genuinely impressive. Friends whose opinions I respect switched from Canon EF glass to the RF ecosystem and were enthusiastic about the results. I borrowed an R6 for a weekend of shooting to see what the conversation was about.

I came back to Sony.

Here's a detailed account of why — not as a dismissal of Canon, which makes excellent cameras, but as an honest explanation of why the Sony ecosystem continues to serve the kind of work I do at Photography Shark better than the alternative.

What I Was Testing For

The work at Photography Shark covers a specific range: Boston headshots, senior portraits, family photos, boudoir sessions, studio work, and event photography. That's a wide range of scenarios with different technical demands.

Headshots require precise, reliable autofocus on a single subject at close to medium range. Senior portraits often happen on location — beaches, trails, downtown areas — where light is variable and subjects aren't always cooperative. Family sessions with young children require fast, accurate tracking AF that can handle unpredictable movement. Boudoir work requires excellent high-ISO performance and flattering skin tone rendering in controlled studio light. Events require quiet operation, strong low-light performance, and the ability to work quickly in chaotic environments.

The Canon R6 I tested is a capable camera. It checks many of these boxes. But in the areas that matter most for this specific mix of work, Sony consistently came out ahead.

Autofocus: The Single Biggest Factor

For portrait work, autofocus is the single most important technical specification after image quality. A missed focus on an eye in a headshot is not recoverable. A soft background is a creative choice; soft eyes are a reject.

Sony's Real-Time Eye AF is the best eye-tracking autofocus system I've used. At the time I was doing my Canon comparison, the Sony A7 IV had been out for about a year and the tracking system had been refined through firmware updates. In practical use during a headshot session, the camera locks on an eye within the first few frames and holds that lock continuously as the subject moves, turns, and shifts weight. I rarely think about focus during a headshot session on Sony — it's reliably handled.

The Canon R6's autofocus is genuinely good. The Dual Pixel CMOS II AF system Canon uses is accurate and tracks well. But in back-to-back testing across a family session with two kids under seven — the most demanding AF scenario I regularly shoot — Sony produced a measurably higher percentage of sharply focused frames in the burst sequences. The difference wasn't dramatic, but it was consistent enough to matter in a professional context where I deliver a guaranteed number of polished images per session.

For events specifically, where I'm shooting in low light with moving subjects at varying distances, Sony's high-density phase-detection array (759 AF points covering 94% of the frame on the A7 IV) gives more flexibility in frame composition than Canon's DPAF. I can place the subject anywhere in the frame without hunting or recomposing, and the camera tracks correctly.

Resolution and Cropping Latitude

The R6 has a 20.1 megapixel sensor. The Sony A7 IV I was using for comparison has 33 megapixels. The A7V, which I've since moved to, has 61 megapixels.

This gap matters for specific reasons.

For large-format printing — something that comes up regularly with graduation and senior portrait clients who want wall-sized prints — resolution directly limits how large you can print before pixel structure becomes visible. At 33+ megapixels, a full-frame image can be printed at 30x40 or larger with excellent results. At 20 megapixels, that print size requires more careful subject-to-frame ratio management and minimal cropping.

More practically for event and candid work: higher resolution gives me cropping latitude in post. If I'm covering an event and can't always position myself optimally — because there's a crowd, because the speaker is moving, because the moment is happening faster than I can adjust my position — I can crop aggressively from a high-resolution file and still have a usable image. At 20 megapixels, that latitude is more limited.

The R5 (45 megapixels) would have addressed this comparison, but the R5 at the time of my testing was priced significantly higher than the A7 IV and came with 8K video heat management issues that weren't acceptable for long event shoots.

Sony's Color Science: The Common Objection, Addressed Honestly

The most common argument for Canon over Sony in portrait work is color science — specifically, that Canon produces more accurate, more flattering skin tones straight out of camera in JPEG or with less post-processing correction in RAW.

This is true, and I'll be direct about it.

Sony's default color profiles, particularly S-Log and the standard color picture profiles, render skin with a greenish tint that requires correction in post. Canon's skin tone rendering is genuinely more accurate out of box. Photographers who shoot JPEG primarily, or who want to minimize post-processing time, have a real advantage with Canon in this regard.

For my workflow, this matters less than it would for a shooter who delivers JPEGs or works with minimal editing. All of Photography Shark's client images go through Lightroom for color correction, tone adjustment, and skin tone refinement regardless of camera system. Building in a specific Sony-to-neutral color correction step in Lightroom is a two-minute addition to the workflow that becomes automatic over time. The image quality advantage in autofocus performance and resolution justifies that tradeoff easily.

That said, I'll acknowledge the complaint. If you're a high-volume shooter who needs to minimize editing time — a wedding photographer doing 500 client galleries a year, for instance — Sony's color science overhead is a legitimate consideration and Canon may serve you better.

The Sony Ecosystem

By the time I was making this comparison, I had invested significantly in Sony G Master glass. The 85mm f/1.4 GM is my primary portrait lens. The 24-70mm f/2.8 GM handles most event and family work. The 135mm f/1.8 GM is on rotation for specific portrait work where I want maximum background separation.

Switching to Canon RF would have meant either selling that glass and absorbing the depreciation cost, or using an adapter (which introduces its own complications). Neither option made economic sense against the performance advantage Canon was offering over my existing Sony setup.

But beyond the economic argument: the G Master lenses are genuinely excellent. The 85mm f/1.4 GM is as sharp as any portrait lens I've used, focuses reliably in low light, and produces the kind of out-of-focus background rendering that portrait clients specifically notice and comment on. There's no Canon RF equivalent I tested that outperformed it.

Sony's ecosystem also includes strong third-party options. Sigma's Art series lenses support full functionality on Sony E-mount bodies through native adapters, and Tamron has built several excellent Sony-native lenses (the 28-75mm f/2.8 G2 in particular) at prices below what first-party G Master glass costs. This gives flexibility for clients on tighter equipment budgets or for specific use cases where premium glass isn't required.

What Canon Gets Right

To be clear about where the comparison is honest: Canon's ergonomics are better. The button layout is more intuitive, the menus are more logically organized, and the grip fits a wide range of hand sizes naturally. Photographers coming from any Canon DSLR background will have an extremely short adjustment curve moving to the RF system.

The R5's dual card slots (CFexpress and SD) are more flexible than Sony's dual SD arrangement on most A7 bodies. For event photographers who shoot video as well as stills, this matters for the higher bitrate video formats.

Canon's customer service reputation is also stronger than Sony's in the professional space. Canon Professional Services (CPS) is a mature, well-organized program with loaner equipment availability and fast turnaround on repairs. Sony's equivalent program exists but is less established.

These are real advantages. For a photographer coming fresh to mirrorless without existing system investment, or one who prioritizes ergonomics and service infrastructure over autofocus and resolution, Canon RF is a legitimate choice that will produce excellent professional results.

The Bottom Line

Choosing between Sony and Canon mirrorless is not a choice between excellent and mediocre — it's a choice between two strong systems with different strengths.

For the specific mix of portrait, event, and studio work that Photography Shark does on the South Shore and in Boston, Sony's autofocus performance, resolution, and the existing lens investment make it the better platform. That judgment holds after serious real-world testing against Canon's current offering.

The best camera is the one you know thoroughly, trust technically, and that consistently delivers the results your clients are paying for. For me, after ten-plus years of professional work, that's Sony.
