📸 APS-C vs Full Frame: Do They Capture the Same Amount of Light?

This question comes up constantly in photography—and the answer is more nuanced than a simple yes or no.

Let’s break it down in a way that actually makes sense.

⸻

🔍 The Short Truth

An APS-C camera and a full-frame camera, both at 24 megapixels and the same aperture (f-number):

❌ Do not capture the same total amount of light
✅ Do receive the same light intensity per unit area

That difference matters—a lot.

⸻

1️⃣ What Aperture (f-number) Really Controls

When you set an aperture like f/4, you’re controlling the brightness of light per square millimeter hitting the sensor.

At the same:
• Aperture (f/4)
• Shutter speed
• ISO

➡️ The brightness of the image projected onto the sensor is the same, regardless of sensor size.

So:
• APS-C at f/4 = same light per mm²
• Full frame at f/4 = same light per mm²

This is where the confusion usually starts.

⸻

2️⃣ Sensor Size Controls Total Light Collected

Here’s the part that changes everything.

A full-frame sensor is physically larger—about 2.3× the surface area of APS-C.

That means:
• It intercepts more of the image circle
• It collects more photons overall
• It has more total signal to work with

Think of it like rain:
• Same rainfall rate (aperture)
• Bigger bucket (sensor)
• More water collected (light)

➡️ Full frame captures more total light

⸻

3️⃣ But Both Are 24 Megapixels—Doesn’t That Even It Out?

No—and this is critical.

If both sensors have 24 MP:
• Full frame pixels are larger
• APS-C pixels are smaller

Larger pixels:
• Collect more photons
• Have higher signal-to-noise ratio
• Perform better at high ISO
• Hold more dynamic range

Smaller pixels:
• Collect fewer photons
• Hit noise sooner
• Require more amplification

So even pixel-for-pixel:
➡️ Full-frame pixels gather more light

⸻

4️⃣ Why the Images Can Look Identical Anyway

If you shoot:
• Same aperture
• Same shutter speed
• Same ISO

Both images can look equally bright on screen.

But internally:
• Full frame has more real signal
• APS-C relies more on amplification

That’s why:
• Noise shows up earlier on APS-C
• Full frame files tolerate pushing shadows better
• Dynamic range favors full frame at the same ISO

⸻

5️⃣ The “Equivalent Exposure” Argument Explained

When people say:

“Full frame gathers more light”

They usually mean for the same framing and depth of field.

To match framing:
• APS-C uses a shorter focal length

To match depth of field:
• APS-C needs a wider aperture

Once you equalize framing + DOF:
➡️ Full frame still captures more total light

That’s the real advantage—not brightness, but signal quality.

⸻

🧠 Final Takeaway
• Same f-number → same light per unit area
• Bigger sensor → more total photons
• Same megapixels → full frame has larger, cleaner pixels

APS-C is efficient and reach-friendly.
Full frame is light-hungry and noise-resistant.

Neither is “better”—they’re just optimized differently.

⸻

If you want, I can:
• Tailor this specifically to wildlife photography
• Add a Canon R7 vs full-frame comparison
• Or convert this into a voiceover script for the video 🎙️

Many make you believe that DSLR’s are substandard. These images are shot on the canon one DX Mark iii with a 20 megapixel camera. The lens is Canon EF 200-400 F4L IS USM +2x tele extender. There’s absolutely nothing wrong with the image quality. Now I challenge you to tell me why you need extreme megapixels. Cropping is not the same as buying quality lenses and filling your frame.
