The Canon PowerShot G1 X Mark II and the PowerShot G5 X are both advanced compact cameras with fixed zoom lenses, but they take different routes. The G1 X Mark II leans on a larger sensor, while the G5 X adds a built-in viewfinder and a more modern compact design. Confirm exact specs on Canon’s own pages.

What each camera is for
The G1 X Mark II is a chunky premium compact built around a sensor that is larger than the one-inch type found in many compacts. It is meant for people who want better low-light behavior and softer background blur from a camera that is not a full system.
The G5 X is a smaller body with a built-in electronic viewfinder, a one-inch type sensor and a bright lens, designed for travel and street use where a viewfinder helps in sunlight.
Key differences
| Trait | G1 X Mark II | G5 X |
|---|---|---|
| Sensor | Larger than one-inch type | One-inch type |
| Viewfinder | Not built in (optional accessory) | Built-in electronic viewfinder |
| Zoom character | Longer reach | Brighter at the wide end |
| Body | Thicker, more rounded | Compact with a raised viewfinder hump |
The lens trade-off is common to this class: a longer zoom range usually comes with a darker maximum aperture, while a faster lens may reach less far.
How to decide
- Decide whether you need a viewfinder. In bright sun, many people find a screen hard to see.
- Think about reach. If you want to frame distant subjects, a longer zoom matters; for rooms and streets, a faster lens helps.
- Consider size. A pocket-friendly camera gets carried more often.
- Check what is still available new or used, and the condition of any used unit, such as battery and lens movement.
Choose which
- Choose the G1 X Mark II if you value the larger sensor and a longer zoom range over portability.
- Choose the G5 X if you want a built-in viewfinder, a faster lens and a body that is easier to carry.
If you buy either camera used, look at the lens for smooth zoom movement, check that the screen and buttons respond properly and ask about the battery. Fixed-lens cameras cannot swap a worn part for another lens, so condition matters more than it would on an interchangeable-lens body.
FAQ
Are these cameras still worth considering?
They are older designs, so many people look at them as used cameras. They can still make sense for a simple, single-lens carry-around camera, but check condition carefully.
Can I change lenses?
No. Both have fixed lenses, which keeps the body small and simple but means you choose the lens range when you choose the camera.
The Short Version
The G1 X Mark II suits those who want a larger sensor and longer zoom, and the G5 X suits those who want a viewfinder and smaller size. Choose by how you like to frame pictures, and verify specs on the maker’s page.
