The Sony A6700 and the Sony A7C II are both compact mirrorless cameras, but the A6700 uses an APS-C sensor and the A7C II uses a full-frame sensor. Choose the A6700 if you want the smallest overall kit with extra reach, and choose the A7C II if you want full-frame image qualities in a body that stays small.
What Each Camera Is For
The A6700 is the advanced model in Sony’s compact APS-C series, suited to travel, action and video. The A7C II is a compact full-frame body aimed at people who want a larger sensor without the bulk of a traditional full-frame camera, such as travelers, street photographers and hybrid creators.

Body Size Is Only Part of the Story
Both bodies are small, so the difference in size shows up mostly in the lenses. A full-frame lens with a wide aperture is usually bigger and heavier than its APS-C counterpart. If you carry a kit of two or three lenses, the total weight on your shoulder can differ more than the cameras themselves.
The reverse is also true for the sensor. In dim light, the larger sensor usually gives cleaner results and easier background blur, which people who photograph indoors or at dusk often value.
How to Choose
- Pack a bag with the lenses you would carry and compare weights using maker figures.
- Think about your typical light and whether background blur matters.
- Decide on reach: APS-C narrows the view, which helps with distant subjects.
- Look at the viewfinder, screen and card details on the maker pages.
- Count the full cost of lenses for the sensor you choose.
Who Should Choose Which
- Choose the A6700 for hiking, wildlife and action where reach and low weight help.
- Choose the A7C II for travel portraits, low-light scenes and a larger-sensor look.
- Use the same E-mount lenses on both when you want flexibility.
Remember that accessories, spare batteries and cases add to the real cost of any change, so count those too, and read the maker’s documents for battery, card and port details before you commit to a purchase.
FAQ
Can the A7C II use APS-C lenses?
Yes, it can, but the image is cropped, which lowers the effective resolution. Full-frame lenses are the better match.
Which is better for video?
Both are capable. Compare recording modes, stabilization and screens from the maker before you decide.
The Short Version
The A6700 is the lightest overall kit with reach, and the A7C II brings a full-frame sensor into a small body. Choose by lens weight, usual light and how much blur and depth you want.
