Description and Reviews

Key Take-Aways:

The S1RII is a full-frame L-Mount mirrorless camera that Panasonic presents as the latest high-resolution model of its LUMIX S Series. Three reviews (Digital Camera World, Photography Blog, Space.com) praise the 8K video and two (Digital Camera World, Photography Blog) praise the price while one review (Space.com) faults it, and two (Digital Camera World, Space.com) fault the lower resolution than the S1R.

From Panasonic:

Panasonic is proud to introduce the new LUMIX S1RII - the latest high-resolution model of the Full-Frame mirrorless LUMIX S Series.

Official Website

Panasonic’s consumer product pages block automated reads, so the maker page above is Panasonic USA’s launch press release of 25 Feb 2025; the quote is its opening paragraph, unchanged. The specs come from that release and from Panasonic Japan’s DC-S1RM2 spec table, its recording-mode list and its product page.

Weight of 795 g is Panasonic Japan’s figure with battery and one SD card (θ³ͺ量 η΄„795g, shoe cover fitted, no body cap). The dimensions are its 134.3 x 102.3 x 91.8 mm, rounded. The price of USD 3,299.99 (rounded to 3300) is the US price in Panasonic USA’s release (“available in late March for $3299.99”), which is body only; DPReview’s spec page could not be read here, so the maker figure is used. Announced on 25 Feb 2025, hence 2025 as the year.

The sensor is 44.3 MP effective (η΄„4,430δΈ‡η”»η΄ ). The release gives 8.0 stops of Body I.S. (CIPA, with the S-R2060), so ibis is true; the Japanese table lists dust- and splash-resistance (ι˜²ε‘΅ι˜²ζ»΄δ»•ζ§˜ marked as present), so weather_sealed is true. The viewfinder is a 5.76 million-dot OLED (η΄„576δΈ‡γƒ‰γƒƒγƒˆ, 0.78x per the table). The mechanical shutter runs to 1/8,000 s and the electronic shutter to 1/16,000 s (speed priority). The lowest standard ISO is 80 (ISO 40 is an extended setting). The table gives 10 fps with the mechanical shutter in speed-priority mode (AFS/MF; 9 fps in quality-priority mode, 8 fps with AFC) and 40 fps with the electronic shutter (SH), and it lists an SH PRE mode with pre-capture, so pre_burst is true. The recording-mode list has 8.1K 3:2 video of 8064x5376 at 23.98p, which is Panasonic’s widest open-gate mode today (6.4K 3:2, 6432x4288, was the launch mode and 8.1K / 7.2K came with the firmware update the release announced), so open gate is 8.1K. The list tops out at 119.88p, reached by 4K (and C4K and FHD), so slow_mo is 4K 120p. The hot shoe is inferred from the hot shoe cover (γƒ›γƒƒγƒˆγ‚·γƒ₯ーカバー) in the table’s accessory list and the shoe cover in the weight note. The table lists CFexpress Type B for slot 1 and SD (UHS-I / UHS-II) for slot 2, and no internal storage, so internal_storage is 0. The table’s USB entry lists UVC support (UVC：対応), so webcam is true; Panasonic’s LUMIX Webcam Software page does not name the DC-S1RM2. The battery is the DMW-BLK22 named in the Japanese table’s CIPA entries and accessory list. Battery life is the CIPA-based figure of about 340 shots with the rear monitor and a CFexpress card (280 with the viewfinder, 350 monitor and SD card) with the S-R24105 lens. The SKU is left out because no US body-only SKU is published on a page reachable for automated reads. Panasonic’s operating range is -10 to 40 degrees C.

Current: Panasonic Japan’s product page still lists the S1RII with no production-ended marking and no discontinuation report was found as of 2026-11-05, so there is no discontinuation year.

Reviews and videos were a full pass because the body is current. DPReview’s review (Mitchell Clark and Richard Butler, 91%) is listed first but could not be read, so it is not used for the Key Take-Aways. TechRadar’s launch-day review states a pre-production unit and Cameralabs’ review states an early sample from a press trip, so neither is listed. Digital Camera World’s launch-day review (25 Feb 2025, updated 8 May 2025) is kept because it states no pre-production unit. Photography Blog’s review (Mark Goldstein, 27 Mar 2025) states none either. Space.com’s review (Gavin Stoker) is written for night-sky shooters and states no pre-production unit; Tom’s Guide’s Oct 2025 piece is an opinion column and is not listed. Points counted for the Key Take-Aways: Digital Camera World praises the 8K video, internal ProRes, the 44 MP sensor with 40 fps and autofocus and the price, and faults the lower resolution than the S1R, the battery life, 8K being overkill for many and the S5 IIX offering strong video for less; Photography Blog praises the video, price, autofocus, screen, viewfinder and stabilisation and the smaller body, and faults the lost top-plate screen and the missing automatic subject-detection option; Space.com praises the build, screen and 8K video and faults the lower resolution than the S1R, the price and the bulk with a lens. Videos with a paid-promotion notice, a Panasonic affiliate link or a unit on loan from Panasonic, launch-day videos and creators’ first looks are not listed. Product image: Panasonic.
