ARTEMIS 1 versus ARTEMIS 2: what changed and what carried over

Note (as of October 2026)Curt O. Schaller, the developer of Artemis and Trinity, has no longer been with ARRI since the end of 2025. To our knowledge, ARRI currently has no dedicated team and no official contact persons for its stabilizer systems. In our view, the future of this line is uncertain. If you are buying new, get written confirmation from ARRI beforehand on how long service and spare parts are guaranteed. Have used rigs checked by the manufacturer before you buy.

What the thread found

ARTEMIS 1 and ARTEMIS 2 are official ARRI product names, registered as trademarks alongside TRINITY 1, TRINITY 2, SRH3 and SRH360 - they are not just operator shorthand for older and newer revisions.
The camera interface is the largest change: ARTEMIS 2 introduces the SAM standard (Stabilizer Adapter Mount), delivered as SAM-2 for ALEXA and SAM-3 for AMIRA, which lets the same camera move tool-free between the stabilizer, a remote head, a tripod and TRINITY.
Power capacity grew by a factor of five. On the earlier generation most top stage outputs are rated 12 V at a maximum of 3 A; ARTEMIS 2 accepts 10.6 to 33.6 V DC and supplies 12/24 V at up to 15 A.
The ARTEMIS 2 stages carry data buses the earlier generation did not have: LBUS on a Lemo 0B 4-pin connector at 24 V and a CAN bus on a Fischer 4-pin connector.
The battery system was rebuilt around 19 mm rods with a BMS-2 base and repositionable mounts, with a jog wheel menu and a simultaneous discharge mode, replacing the mechanical battery hanger with its pendulum and dovetail.
The 1.8 in carbon centre post family carried over. On the earlier generation it telescopes from 43 to 72 cm (16.9 to 28.3 in) with a fine trim range of 22 mm in total, plus or minus 11 mm; on ARTEMIS 2 the same post is two-stage with a tool-free clamp and tool-free fine trim.
The gimbal also carried over: 1.8 in post, 15.9 mm (5/8 in) arm posts, no-tool clamp lever, knurled handle at 50.8 mm and curved handle at 26 mm, with a patented self-centring friction ring that aligns the main bearing to the post rather than clamping it.
ARTEMIS 2 is explicitly designed for conversion to TRINITY 2, and weighs 7.4 kg (16.3 lb).
The Artemis sold under Sachtler, before ARRI took the line over, uses a 1.5 in centre post. That is the Steadicam standard diameter, so a Tiffen Volt fits a Sachtler Artemis - a cross-manufacturer compatibility that neither company's documentation mentions, because it concerns the other one's product.
Operators with a first-generation Artemis do ask how to run a Volt on it, repeatedly, and the answer given in the field is that the manufacturer supplies it directly as a set comprising the control block, the cables and the gimbal. The open practical question is where the block mounts on that sled, not whether the post diameter fits.

Depends on

Taken from ARRI product documentation, not from a forum discussion: the ARTEMIS 2 user manual version 1.1 dated 2022-09-01 and the certified TRINITY generation 1 training material.
Figures describe the state at publication. ARRI states that specifications may change without notice and refers to current data sheets.
The note on the Sachtler Artemis 1.5 in post and Volt compatibility comes from operator practice, not from a manufacturer document. It applies to the Sachtler-branded Artemis, not to the later ARRI models.
