Mirrorless Cameras: Sensor Size, Kits and Lenses

Body only, lens kit or accessory bundle

Listings come as body only, with a kit lens such as 16-50 mm or 24-70 mm, or as a bundle with extras. A kit lens is the quickest start, and a zoom range covers everyday shooting. Bundles that add cards, bags and filters in a numbered accessory pack can look generous, but the extras are often generic; judge the camera and lens first. If you already own lenses for the same mount, body only avoids buying a second lens.

Sensor size, megapixels and handling features

Sensor size shapes image quality more than megapixels do. Micro Four Thirds sensors allow compact lenses, APS-C is the popular middle, and full-frame handles low light best at the cost of larger bodies and lenses. A resolution of 24 to 26 MP is plenty for prints and screens; 33 or 61 MP helps cropping and large prints but fills cards faster. Also check the hybrid autofocus, a tilting or flip-out screen for vlogging, a hot shoe for flashes and microphones, and image stabilisation in the body.

Questions about Mirrorless Cameras: Sensor Size, Kits and Lenses

Is a kit lens good enough?

For travel, family and everyday photos, yes: a standard zoom covers wide to short telephoto and is light. Faster prime lenses add shallower depth of field and better low-light results, so treat the kit lens as a starting point.

Do more megapixels mean better photos?

Not by themselves. Sensor size, lens quality and light matter more. Extra megapixels allow heavier cropping and bigger prints but create larger files and can show more noise at high ISO on a small sensor.

Can I use my old lenses on a mirrorless camera?

Often yes with a mount adapter, but it must match both the lens mount and the camera mount. Autofocus and stabilisation may be limited or lost, so check compatibility notes for the specific lens and body before choosing.
