Most photographers chase headline specs and flagship hype. Here are five “wrong” opinions that are usually right in the field.
Micro Four Thirds Is the Most Rational Travel System
When the job is “be there, get the shot, and carry it all day,” Micro Four Thirds offers a brutally efficient proposition: more reach per ounce, fantasticx stabilization, and a compact lens catalog built for mobility. Smaller sensors don’t only change image quality curves; they reshape what you can realistically put on your shoulder for sunrise to sunset. A 300mm lens that behaves like a 600mm field of view is suddenly an everyday tool, not a once-a-year rental that requires a monopod and a back brace. That means hand-held birds-in-flight at golden hour, mountain switchbacks without a penalty, and city travel where your “big lens” doesn’t scream "big lens."
Micro Four Thirds thrives on synergy. In-body stabilization (IBIS) and lens stabilization often work together so you can shoot at slower shutter speeds with crisp results, which lets you keep ISO lower without dragging a tripod everywhere. The system’s lighter glass also balances better on compact bodies and gimbals, which quietly reduces shake and missed frames. And because the ecosystem emphasizes practical focal lengths and close-focusing designs, many lenses double as quasi-macro tools for field detail and food photography on the same trip.
“Yeah, but noise.” That’s the classic rebuttal. It does matter, especially if you habitually push past ISO 6,400, but the counterpoints are real: stabilization that buys you 3–7 stops on static subjects, modern denoising that deals gracefully with fine-grain structure in raw files, and field craft that favors exposure discipline over ISO roulette. In travel and wildlife, the biggest performance killer isn’t always sensor size; it’s missing the moment because your kit was too heavy, too conspicuous, or back in the hotel.
How to Make It Sing
-
Build a two-lens kit: a weather-sealed standard zoom and a compact telephoto (e.g., “300mm that behaves like 600mm”). You’ll cover wildlife, city scenes, and food without swapping bags.
-
Exploit IBIS: practice breathing technique and shutter discipline so 1/60 at medium tele becomes routine, not risky.
APS-C Is Plenty for (Most) Paid Work
Most client deliverables live on screens, social feeds, slide decks, and prints that rarely exceed 24×36 inches. APS-C systems hit a sweet spot of resolution, autofocus, and portability that keeps your keeper rate high and your workflow nimble. You get meaningful “free reach," while still enjoying mature color pipelines, reliable tracking, and sane file sizes that don’t choke your laptop or your cloud bill.
There’s also a quiet economic truth: APS-C bodies and lenses are cheaper, and cheaper often multiplies into “more.” More batteries. More backup bodies. A second light. A better tripod. Those compound into reliability and consistency that clients feel even if they can’t name the sensor inside your camera. Meanwhile, modern APS-C sensors handle ISO 3,200–6,400 with confidence, and thoughtful lighting or stabilization usually beats spiraling into high-ISO territory anyway.
If you also shoot video, the equation gets better. APS-C avoids the most punishing rolling-shutter artifacts of some high-resolution full frame bodies and frequently delivers oversampled footage with sharp detail. That means you’re delivering clean, confident work to clients who judge results, not spec sheets.
How to Make It Sing
-
Build around a two-zoom plus a fast normal trio: a compact standard zoom, a tele zoom, and a 35mm or 50mm prime for low light and look.
-
Calibrate for speed: set focal-length-aware Auto ISO, map AF modes to custom buttons, and save stills/video banks so you can flip roles without menu fishing.
-
Print a big sample: hang a 24×36 from your APS-C kit. Seeing it on a wall ends the resolution anxiety.
24–200mm+ Superzooms Are Good Enough
“Good enough” is heresy in gear forums, but in the field, it reads as “right place, right time, right focal length (and no painful back).” Modern superzoom lenses deliver honest sharpness, effective stabilization, and useful close-focus while removing 90% of the lens-swap moments that cause missed shots. For a lot of scenarios, that friction reduction is everything. You’re on the right focal length now, not in 12 seconds after the moment passes.
Do you trade a bit of maximum aperture and pixel-peeping perfection? Sure. But most modern superzooms sharpen up beautifully by f/5.6–f/8, are corrected in-camera for distortion and vignetting, and respond well to thoughtful post. Pair them with high-resolution sensors and you can crop to longer focal lengths on demand without packing something like a 500mm. Add a compact prime to your bag for low-light character or shallow depth of field and you’ve got a two-piece kit that covers local sports at noon, street scenes at dusk, and dinner portraits without breaking stride.

How to Make It Sing
-
Learn the lens: every superzoom has sweet spots. Test yours at common focal lengths and apertures; memorize where contrast and detail peak.
-
Use stabilization intentionally: at the long end, brace and control your breath. Let IBIS/OIS handle the micro-shake while you nail the moment.
-
Bring one small fast prime: for indoor ambient light or deliberate subject isolation, that prime gives you the “wow” look without hauling a full second kit.
f/4 Lenses Are Highly Underrated
It’s easy to romanticize f/2.8 zooms and f/1.2 primes, but the total cost of that last stop includes price, weight, balance, fatigue, and price. Did I mention price? High-quality f/4 zooms and f/1.8 primes solve most problems with less mass and more range, which translates directly into more time on target and a steadier hand by hour three. On modern sensors, the “lost stop” is often a non-issue: stabilization lets you slow the shutter on static subjects, compact flashes provide clean bounce indoors, and high-ISO performance is more than enough compensation.
Optically, f/4 zooms from the last few generations are shockingly consistent across the frame, especially at landscape apertures like f/5.6–f/11. Many focus closer than their faster siblings, adding versatility for product and detail work. And because they’re lighter, they pair better with travel tripods, sliders, and gimbals, keeping your whole system inside more comfortable support limits.

How to Make It Sing
-
Build around two f/4 zooms that cover 24–200mm equivalent. Add a single fast prime at your favorite storytelling focal length.
-
Favor lenses with good stabilization.
Global Shutter Isn’t Essential for Most Shooters
Global shutter is a technological triumph: no rolling distortion, incredible flash sync, and perfectly frozen propellers. But for 95% of photography, fast-read rolling shutters already mitigate the issues that used to haunt electronic shutters. Today’s stacked sensors shorten readout drastically, which means panning looks natural and vertical lines stay vertical. Meanwhile, the tradeoffs for early global-shutter systems, namely price premiums and dynamic range compromises, aren’t always worth it outside niche scenarios.
Ask what you actually shoot. Sports under brutal LED lighting with ad boards? High-speed studio work where you want to sync fast without high-speed sync? Aerial propellers with lateral motion? If those are your daily realities, the value is obvious. But for events, portraits, travel, documentary, and most commercial stills, a modern stacked-sensor camera checks the boxes with fewer drawbacks. And because these systems are now widely available at mid-tier prices, you can pair a fast-read body with better glass or lighting for the same budget as one global-shutter flagship.
For hybrid shooters, fast-read sensors have also improved video rolling shutter performance to the point where whip pans and handheld moves no longer look like gelatin. Add anti-flicker tools, shutter-angle controls, and high-frequency scan modes, and you can largely tame the environments that used to demand specialized hardware.
How to Make It Sing
-
Use anti-flicker shot timing for stills and high-frequency scan (or fine shutter-angle steps) for video to squash bands before they start.
-
Favor stacked-sensor bodies when you upgrade. The readout speed upgrade is the visible real-world win most shooters feel immediately.
The Practical Buyer’s Playbook
It’s one thing to nod along and another to commit budget. Use these quick checks to keep your shopping honest.
Match the system to the mission. If you hike, fly, or chase wildlife, weight and stabilization are performance features, not luxuries. Micro Four Thirds makes sense because it keeps you shooting in places where heavier kits stay zipped.
Shop for balance, not just aperture. If a lens makes your rig nose-heavy, your minimum shutter speed quietly rises and your wrist tires sooner. An f/4 zoom you can hold steady beats an f/2.8 you fight all day.
Prioritize range and focus behavior. A 24–200mm replaces lens swaps with moments captured.
Buy for the workflow you have. Moderate-resolution files move through your computer and cloud faster.
Spend where it multiplies. A good support system, dependable lights, and extra batteries create more usable frames than chasing one more stop on a lens you only shoot at f/4 anyway.
Field Scenarios That Prove the Point
Urban weekend with one body. A compact APS-C body, a 24–200 superzoom, and a 35mm prime fit in a small sling. You cover street details at 24mm, skyline compression at 200mm, and dinner portraits with the 35mm at f/1.8. You never swap bags, never miss the subway, and still bring home a sequence that looks intentional.
Birding on a boardwalk. Micro Four Thirds body, weather-sealed 300mm (behaves like 600mm), and a lightweight monopod. You hold position without blocking the path and your shoulder isn’t destroyed by noon.
Corporate off-site. APS-C body pair, two zooms, on-camera flash with small modifier, and a compact stand with a bounce umbrella. You shoot candids in conference rooms, quick headshots by the window, and evening awards without demanding a power drop or a rolling cart.
Dawn landscape on a carry-on. f/4 wide zoom on a light full frame body, travel tripod, ND, and polarizer. You shoot at f/8 anyway, stack a few long exposures at ISO 100, and carry everything to a second viewpoint without a shuttle run to the car.
High school gym. Stacked-sensor body with fast readout, tele zoom, anti-flicker on. You leave with consistent color and exposure across a full quarter without bands or skew.
Handling 'But What About…' Objections
“I need shallow depth of field.” Great—carry one fast prime that earns its keep. Shoot it when look matters, then go back to the f/4 zoom that keeps you nimble.
“I print big.” Run a controlled test: shoot the same scene on APS-C and full frame, process with your standard workflow, and print at 24×36. If you can’t tell at viewing distance, your audience can’t either. Spend your savings on calibration, paper, and framing.
“Superzooms distort.” Modern bodies correct distortion and vignetting in raw processing. For architecture or stitched work, bring the lens that suits the job. For everything else, superzooms are a storytelling machine.
“Global shutter is the future.” Likely, but you buy for today’s needs. If your work truly benefits (studio flash at extreme sync, specialty sports, scientific imaging), go for it. Otherwise, fast-read sensors already solved most practical problems.
Why This Approach Works
Gear is only “best” when it multiplies your chances to be present, composed, and comfortable at the exact second something worth photographing happens. Micro Four Thirds wins by making “long” normal. APS-C wins by putting pro performance in lighter, cheaper packages. Superzooms win by replacing a dozen micro-decisions with one decisive frame. f/4 wins by trading theoretical speed for all-day balance. Fast-read sensors win by solving yesterday’s electronic-shutter pain without new baggage.
The meta-lesson is to optimize for how you actually move through shoots, not for how you imagine you might someday shoot a lab chart. If a choice increases your keeper rate, reduces fatigue, and speeds your workflow, it’s a pro choice, even when the spec sheet looks “lesser.” Pick the tools that keep you out in the world and inside the moment. The rest is forum noise.
Excellent article, Alex.
I happen to mostly agree with everything you have written here. The only difference that we have is that I believe that there are some exceptions, and the exceptions are valid, and should be accepted instead of being dismissively reasoned away.
I mean there actually are instances when a M43 or APS-C sensor is not good enough to produce the desired depth of field or the desired image quality. The majority of the time, these smaller sensor bodies will do exactly what we need them to. But exceptions do really exist and there are cases where using a different lens or viewing a print from further away isn't a good enough solution.
But yeah for 80% of what most of us shoot the little sensors are plenty good enough.
I don't think he dismissively reasoned away anything. He said MFT are a rational choice for travel. He said APS-C is plenty for (most) paid work conditioned on how it will be used. He reasoned that if you can print at 24x36 and not see a difference at normal viewing distances, your audience won't either. Nothing controversial about any of that. There are cases where a full frame sensor and lenses are best and cases where they are overkill and make a photographer spend more and carry more weight for no good reason.
If someone says "the tiny sensor doesn't produce shallow enough depth of field for some of the images I want to create" and someone responds by saying, "well then use a fast prime for those shots" ..... that would most definitely be dismissively reasoning away the photographer's concerns about the camera's shortcomings.
There is another writer here who routinely dismissively reasons away any concerns anyone ever posts about the shortcomings of the small M43 sensors. He has never, even once, admitted that there are some jobs for which it is not the best choice. This boneheaded behavior is offensive to me. Alex is not at all boneheaded and I respect the way he presents his insights and opinions because he always* qualifies his statements instead of making blanket absolutist statements.
* except in a few of the titles he has written
I have MFT, APS-C and full frame cameras. There are cases where one is better than the other for various reasons. But some folks never fail to get exercised as if we have cursed their child when someone says MFT/APS-C is 'good enough' for many if not most people and situations. Size/weight/cost are real advantages of MFT/APS-C. That is not a diminishment or dismissal of FF at all.
I agree with you.
For many years, I used FF, APS-H, and APS-C sensor cameras almost equally, constantly switching from on body to another to another while afield.
What an APS-C sensor could do great could not be done with a FF sensor (deep corner sharpness and brightness, no vignette at all).
Conversely, what I could get from a FF sensor, in terms of the way the out-of-focus areas were blurred, I could not possibly replicate with an APS-C sensor.
Different tools for different jobs and different output.
NOTE: This is coming from someone who spends a shameful amount of time examining and assessing and enjoying images on a large hi-res computer monitor and in print. Small differences that may not even be noticed by regular people are monumentally enormous big deals to me. Like if an out-of-focus leaf in the distant background of a deer photo doesn't look exactly the way I want it to, it drives me crazy with discontent, and I may spend a half hour Photoshopping that leaf to try to get it to look exactly the way I think it should look. Yes, even if it is really small in the frame, something that most people would never even see. For someone as anal-retentive and picky as I am is told that something is "good enough", it makes me feel utterly exasperated, because whoever is saying that just doesn't seem to understand how extremely important all these minuscule parts of every photo matter so very very much to me. Yeah, a blade of grass or a tiny leaf way way way behind my subject will totally ruin a photo for me if it isn't rendered exactly the way I want it to be. It is from this mindset that my opinions about sensor size is coming from.
No nonsense good advice.
I love my Olympus Pen-f digital. The compact and featherweight 14-42mm produces a 28-84mm angle of view.
