List of lightest mirrorless cameras

This is a list of the lightest and smallest mirrorless digital cameras ever released with an interchangeable lens mount, excluding smartphones and action cameras, sorted by weight including battery and memory card.

Nearly all the lightest models have been discontinued, as smartphone cameras have rapidly improved and taken over their market. Some high-end smartphones now exceed several of these models in weight, sensor size, and functionality. (For example, an iPhone 15 Pro Max weighs 221 g, and a Galaxy S24 Ultra weighs 233 g.)

The lightest mirrorless cameras in production today are the Olympus E-P7 at 337 g and Sony ZV-E10 at 343 g. The lightest models in production with an electronic viewfinder (EVF) are the Panasonic G100D at 346 g and Canon R100 at 356 g. With the exception of the E-P7's in-body image stabilization (IBIS), these models eschew certain hardware features, such as IBIS and weather sealing, that add weight. Most newer models include one or more of these features, as the bulk of the mirrorless camera sector has moved upmarket.

Of these ultracompact models, the Micro Four Thirds cameras (Panasonic GM1, Panasonic GM5, and Z CAM E1) have by far the largest sensor, with an area nearly twice as large as Samsung's and Nikon's "1-inch" sensors and nearly eight times as large as the Pentax Q's sensor. On the other hand, Pentax was able to include in-body image stabilization in their Q-series bodies, because of the tiny sensors.

Lightest mirrorless cameras with an APS-C sensor
The lightest mirrorless cameras in production today with an APS-C sensor are the Sony ZV-E10 at 343 g, Canon R100 at 356 g, Canon R50 at 375 g, Sony ZV-E10 II at 377 g, and Fujifilm X-T30 II at 383 g.

Lightest rangefinder cameras with a full frame sensor
All rangefinder cameras (including digital Leica M-series cameras) are technically mirrorless, because they do not contain a mirror. However, rangefinder cameras are usually not considered mirrorless cameras, a differentiation dating back to when they co-existed with SLR film cameras. More specifically, rangefinder cameras lack autofocus and employ a very different manual focusing method involving a rangefinder mechanism with an optical viewfinder. Furthermore, most digital rangefinder cameras (except Leica's recent models) lack live preview, which is sometimes considered a defining feature of mirrorless cameras.

Lens-style cameras
Lens-style cameras are lighter than all other interchangeable lens cameras with their respective sensor sizes, but they are usually not classified with other mirrorless cameras because they have no screen or viewfinder.

They are designed to be attached to a smartphone so that the phone’s screen can be used as the camera’s display.

Industrial cameras
Sony introduced a mirrorless camera designed for industrial applications that has no screen or viewfinder and no internal battery. It is lighter than all other full-frame interchangeable lens cameras, and as with other modular cameras it is designed to be attached to other hardware, e.g. a drone.
