Should we trust social media influencers repeating full-frame sales lines while reviewing Olympus and OM System cameras? Why is it important to sell the idea that FF cameras capture more light? Shouldn't we reject new sources of light if they're not listed in the exposure formula? Did full-frame advocates discover a new light source that improves image quality? Why would they reject the idea of using the exposure mix to manage the sensor's efficiency? Isn't the sensor's operating efficiency a function of the exposure mix, or did sensor size replace ETTR (managing the sensor's saturation)? Let's take a look at what camera and lens combo I used while reviewing these full-frame theories.
Why did Olympus sell an innovative and promising imaging business?
PS. Folks, ask why?...if you didn't know it's possible to manage your sensor's efficiency.
The lovely town, Meersburg am Bodensee. This is a handheld image with an aperture of f6.3 and no focus stacking.
The photos help illustrate the benefits of the new digital MFT sensor format and the TruePic imaging process. I converted and prepped these images in OM Workspace. Imagine using your camera's TruePic imaging processor to verify and adjust your camera settings with your PC and Workspace.
Which camera and lens did I use?
Hint:- Consider MFT lenses receiving negative feedback on social media. Why would some reject these great lenses? Start by listing those MFT lenses receiving the bulk of negative feedback...
PS. You will discover great M.Zuiko lenses as you learn to walk away from the noise on social media...
I used the 4/3rds aspect ratio for both the landscape and portrait versions...
Why would FF advocates continue to promote the idea that large sensors capture more light in 2026? One of the reasons marketers created the "bigger is better" theory was the physical size of full-frame DSLRs and lenses. They needed a commercial counter for the high sales Olympus experienced with the innovative designs and the size and weight benefits of the E-M5 and E-M1 from 2012/13.
The capture-more-light theory is critical to FF advocates because it explains the promise of less noise and more dynamic range, which are theoretically linked to the designed saturation level of the image sensor. The exposure formula has 4 exposure variables (shutter speed, aperture, ISO, and the average scene luminance). Three of these determine how much reflected light is exposing the sensor. More light (ETTR) means optimizing the sensor's efficiency. The more-light theory suggests that the size of the sensor (not pixels) captures light, which explains FF sensor saturation, noise, and dynamic range. Some refuse to acknowledge that image sensors have a noise floor, varying SNRs, and an optimum dynamic range. That simply means trust the sensor because knowledge is irrelevant.

Typical FF sales lines include a shallower depth-of-field (DOF) and the promise of full-frame cameras offering less noise with more dynamic range. Depth of field is an optical characteristic linked to the sensor's image circle, whereas noise and dynamic range are 2 of many technical characteristics linked to the design criteria, manufacturing, and the materials used to manufacture sensors. Think of gold-plated connectors in high-end sound systems versus more cost-effective connectors.
Instead of focusing on more accurate information, marketers doubled down on "bigger is better" with questionable programs such as astroturfing and repetition. For example, portrait photography with a shallow DOF became important when the benefits of having a deeper DOF were introduced. The "capture more light" theory was introduced to explain more dynamic range and less noise. It would have been better to simply explain ETTR (higher SNRs) with the photons-to-electrons graph.
There would have been no need for this article if it weren't for the constant "bigger is better" noise from photography forums and YouTubers reviewing and discussing Olympus and OM System cameras. All photographers will benefit from more reliable information about digital cameras.
PS. Study the photons to electrons graph for more on sensor saturation (dynamic range) and SNR (noise).
I used different picture modes and iEnhance options for my Workspace raw conversions in this article...
I used exposure, iEnhanced options, and tonal controls to "develop" some of these photos...
How do I research marketing trends and the Olympus and OM System digital imaging process? I have an engineering and marketing background, which helps to follow marketing trends and technical points relevant to digital photography. I used to share my thoughts on photography forums. Today I use AI to research technical information and to follow marketing trends. I focus on basic engineering principles as I study and explain digital cameras and the Olympus imaging process. I believe every photographer will benefit from accurate information and more advanced digital photography principles.
Folks, my goal is not to convince you that one format is superior. It's to encourage you to evaluate them as a complete imaging system consisting of the camera, lens, and imaging process. Judge them by the joy and enthusiasm for using a specific system and the photographs they inspire.
See this article and this article for more on image noise and dynamic range.
PS. I used the OM System OM-5 with the tiny Olympus M.Zuiko 9-18mm f4-5.6 lens. It should be clear why they hate this lens!
