The mirrorless versus DSLR debate is the question Alan Photo answers more than any other. Both types of camera produce outstanding images. The differences come down to how they work, what they prioritise, and which one suits your shooting style. This guide covers everything you need to know to make the right decision.
How DSLRs Work
A DSLR (Digital Single-Lens Reflex) camera uses a physical mirror inside the camera body. When you look through the viewfinder, you are seeing exactly what the lens sees via a reflection from that mirror. When you press the shutter, the mirror flips up, the shutter opens, and light hits the sensor to capture the image. This mechanical process is what gives DSLRs their satisfying shutter sound and their optical viewfinder.
How Mirrorless Cameras Work
A mirrorless camera has no mirror. Light passes directly through the lens onto the sensor at all times. The electronic viewfinder (EVF) shows you a live digital preview of the image as the sensor sees it. This means you can see exposure, white balance, and depth of field adjustments in real time before you press the shutter.
The Real Differences Between Mirrorless and DSLR
- Size and weight: Mirrorless cameras are generally smaller and lighter because they have no mirror box. However, high-end mirrorless cameras like the Panasonic Lumix S5II are still substantial in size.
- Autofocus speed: Modern mirrorless cameras have a significant advantage here. Phase-detection autofocus built directly into the sensor means mirrorless cameras track moving subjects faster and more accurately than most DSLRs. This matters a lot for sports, wildlife, and video.
- Battery life: DSLRs win comfortably. Because the sensor is only active when you press the shutter, DSLRs use far less power. Mirrorless cameras run the sensor continuously, draining batteries faster. The Canon EOS 1500D delivers over 500 shots per charge. Most mirrorless cameras deliver 200 to 400.
- Video quality: Mirrorless cameras are better for video. The Canon G7X Mark III shoots 4K. The Panasonic Lumix S5II shoots 6K. Most DSLRs max out at 1080p and have limited autofocus tracking during video recording.
- Lens selection: DSLRs like the Canon EOS 1500D use the EF mount, which has thousands of lenses available at every price point. Mirrorless cameras use newer lens mounts (Canon RF, Sony E, Panasonic L-mount) with a growing but smaller selection.
- Viewfinder experience: DSLR optical viewfinders show you the real world. EVFs show a digital preview that can lag slightly in very low light. Many photographers prefer the optical viewfinder for landscape and street photography. EVFs are more useful for exposure preview.
Which One Should You Buy in Singapore?
Choose a DSLR if you: are a beginner learning photography, shoot mostly stills, prioritise battery life, want the largest lens selection at the lowest prices, or have a budget under SGD 800.
Choose mirrorless if you: shoot video as well as stills, want the fastest autofocus for sports or events, are willing to invest in newer lens systems, or want the most future-proof technology available.
The Honest Answer from Alan Photo
If you are just starting out and budget matters, get the Canon EOS 1500D. It will teach you photography without any limitations and the image quality is excellent. If you are ready to invest and want a camera that covers both photo and video with professional results, the Panasonic Lumix S5II or Canon EOS R range are the right choices. Come into either of our Singapore stores and we will put both types in your hands so you can feel the difference for yourself.
Frequently Asked Questions
Is mirrorless better than DSLR?
Mirrorless cameras have technological advantages in autofocus and video. DSLRs still win on battery life and lens selection. Neither is objectively better. The right choice depends on your use case.
Are DSLRs becoming obsolete?
Major manufacturers including Canon and Nikon have shifted their development focus to mirrorless. However, DSLRs will remain excellent cameras for many years and continue to be available with full support.
Can I use my old DSLR lenses on a mirrorless camera?
In most cases yes, with an adapter. Canon EF lenses can be used on Canon RF mirrorless bodies with the official EF-EOS R adapter. Autofocus performance is generally maintained.
