Sigma FP2 Debuts with 6K Video and Built-In 70GB Storage

Sigma has introduced the FP2, reclaiming the crown for the world's smallest full-frame mirrorless camera. The new model brings a partially stacked 24.5-megapixel sensor, 6K open gate recording, and an unexpected 70GB of integrated internal memory.

More power inside an even smaller frame

Sigma has never followed conventional mirrorless playbook rules, and the Sigma FP2 doubles down on that modular philosophy. According to early testing details from TechRadar, the new camera trims down the silhouette of the original FP while cramming in significantly more capable internals.

At the heart of the FP2 sits a partially stacked 24.5-megapixel full-frame sensor. It enables 6K open gate capture using Sigma's L-Log profile, as well as RAW video output when connected to an external SSD. Autofocus gets a notable lift through a hybrid phase-detection setup that tracks a broader range of subjects with a 15% claimed improvement in speed and precision.

Rather than forcing shooters to rely purely on memory cards from the jump, Sigma built 70GB of storage directly into the camera body. That gives creators a built-in safety net on set or a way to strip the rig down to the bare essentials for ultra-light run-and-gun street shooting. It is a welcome hardware shift in an era where modern imaging gear is constantly renegotiating size constraints, much like how Amazon Blink adds 4K video and a 7,000-foot wireless range by rethinking everyday enclosure designs.

The trade-offs of going tiny

Keeping the footprint this small means Sigma had to leave standard mirrorless staples on the cutting room floor. The FP2 lacks in-body image stabilization (IBIS), putting it at a handheld disadvantage against rivals like the Lumix S9 or full-sized hybrid bodies.

There is also no integrated electronic viewfinder or built-in handgrip. Sigma expects shooters to treat the FP2 as a modular core. You can mount a crisp 5.76-million-dot tilting EVF accessory to the side, but that modularity comes with a sting: original FP accessories are not backward compatible with the FP2, and vice versa.

The Sigma FP2 remains an acquired taste, but it deserves credit for refusing to blend into the sea of identical hybrid bodies. Omitting IBIS will frustrate casual videographers, yet drone operators, gimbal users, and cinema rig builders will love the shaved dimensions and internal 70GB drive.

Availability and pricing

Sigma has not yet announced formal retail pricing or shipping dates for international markets across North America and Europe. While the base body is framed as competitively priced against compact full-frame rivals, buyers should factor in the cost of essential add-ons, particularly the external EVF and bolt-on grips.

By pairing an upgraded sensor and built-in storage with its modular ethos, the FP2 cements Sigma's reputation for engineering daring hardware that prioritizes pocketable utility over broad mainstream appeal.

Frequently asked questions

Does the Sigma FP2 have in-body image stabilization?

No. To maintain the world's smallest full-frame dimensions, Sigma omitted in-body image stabilization, requiring you to rely on optically stabilized lenses, gimbals, or tripods.

Can I use original Sigma FP accessories on the FP2?

No. Sigma altered the dimensions and mounting configuration for the FP2, meaning original FP accessories are not compatible with the new body.

How much internal memory does the Sigma FP2 have?

The FP2 includes 70GB of built-in storage, allowing you to capture high-resolution stills and video internally without an external memory card installed.
