Leica SL3-P First Look: A 44MP Full-Frame All-Rounder

Leica has been building full-frame mirrorless cameras since 2015, when the original SL arrived. The lineage runs back a good deal further: the 35 mm camera was invented more than a century ago at Leitz in Wetzlar, and its direct descendants are still made today as the Leica M series, most recently the Leica M EV1. The SL line has widened steadily, from that single model to the second-generation SL2 and SL2-S, and it now runs to three bodies: the detail-focused 60 MP SL3, the fast, low-light 24 MP SL3-S, and the newly announced SL3-P, which sets out to be both at once.

This is a first look drawn from a published preview of the camera rather than a full laboratory test or a trial of our own, so the impressions below are early ones and a final verdict is still to come.

The SL3-P takes its body wholesale from the SL3 and SL3-S, and the only external clue as to which model you are holding is the lettering on the viewfinder housing: white on the SL3-P, as on the SL3, and black on the SL3-S. It is a substantial camera at 15.1 x 10.8 x 8.5 cm and 768 g without battery or memory card, yet the deep grip keeps it comfortable in the hand even when it is carrying larger and heavier lenses.

Weather sealing is thorough, and unusually the manufacturer publishes a formal figure for it. The SL3-P is certified to IP54, meaning protection against dust in harmful quantities and against splashing water from every direction. Few camera makers commit to an IP rating at all, so a published figure is worth something in itself. The menu system, as on other recent Leica models, is clear and logically arranged; photographers who normally shoot with another brand should find their way around quickly.

The SL3 chases outright detail with its 60 MP sensor, and the SL3-S prioritises speed and low-light performance with 24 MP. The SL3-P deliberately sits between the two, pairing a full-frame sensor of roughly 24 x 36 mm with a 44 MP resolution of 8144 x 5424 pixels — the same pixel count as the Panasonic Lumix S1R II.

Leica claims the sensor stays sensitive despite that higher resolution, quoting an ISO range reaching 200,000, which matches the SL3-S. In initial shooting the files held up well as far as ISO 6400. How the sensor genuinely compares with its two siblings, and with rival full-frame bodies, is a question only a full test can settle.

Autofocus is the clearest area of change. Leica has reworked the system, promising improved subject recognition along with fast and accurate focus tracking, and has increased the number of measurement points: the SL3-P focuses using the quicker Phase-Change method across 819 points. Early use left a good impression, though a considered judgement will have to wait for a full test.

Continuous shooting rises too, to as much as 40fps. That is a clear step beyond the SL3-S, which managed a measured 29.4fps. Such a rate fills the camera's 8 GB buffer quickly — it is full after around 70 frames — so sustained burst shooting will depend heavily on how fast the memory card can clear it. There are two card slots to help: one for very fast CFexpress Type B cards, one for SD.

Like the SL3-S, the SL3-P is built with video firmly in mind, and it goes further by adding 8K capture: 7680 x 4320 pixels in 16:9, or 8128 x 4288 in the slightly wider 17:9 format. The list of video modes runs to nine pages and takes in a great many professional options.

Among them is an Open Gate mode, which records almost the entire sensor area at 8064 x 5376 pixels. That yields an unusually flexible master file: the framing can be adjusted afterwards, cropped to 16:9 for television or YouTube, or to a vertical format for Instagram and TikTok. The camera also records in Apple's ProRes format, and will write ProRes to the in-camera memory card provided that card is a CFexpress. RAW video can be captured to an external recorder over HDMI.

Leica announced two lenses alongside the camera. The Summilux-SL 50 mm f1.4 is claimed to be the smallest full-frame system camera lens with autofocus, and is aimed at low-light work and at portraits calling for shallow depth of field and attractive bokeh. The Apo-Macro-Elmarit-SL 100 mm f2.8 is built for top-quality close-up photography, though its short telephoto focal length also makes it a natural portrait lens. Both are due at the end of 2026.

None of this is affordable. In the UK the SL3-P body is listed at £5,150, and it is sold as a special-order item: delivery typically takes at least four weeks, with payment taken only once stock is ready to be despatched.

Kits climb steeply from there. Expect £6,100 with the Vario-Elmarit-SL 28-70 mm f2.8, £6,480 with the Vario-Elmarit-SL 24-70 mm f2.8, and £8,560 for the pairing of the 24-70 mm f2.8 and the 70-200 mm f2.8. The two new lenses are listed at £2,110 for the Apo-Macro-Elmarit-SL 100 mm f2.8 and £3,890 for the Summilux-SL 50 mm f1.4.

On this early showing the SL3-P reads as a considered all-rounder rather than a specialist: a 44 MP sensor pitched between resolution and sensitivity, a quicker 819-point autofocus, 40fps bursts and a deep 8K video toolset, wrapped in the rugged, IP54-rated body and clear menus the SL line already had. The price places it firmly in professional territory, and the 8 GB buffer looks like the most obvious practical brake on that headline burst speed. Whether it genuinely combines the strengths of the SL3 and SL3-S, rather than simply landing between them, is what a full test will need to establish.
