Leica SL3-P Review: 45 Megapixels, 8K Video, and a Real Autofocus Upgrade

The Leica SL3-P sits in an interesting position: a 45-megapixel hybrid that Leica designed to land between the speed-focused SL3-S and the resolution-heavy SL3, and the question of whether it actually pulls that off has real stakes if you're considering dropping serious money on any of the three.

Coming to you from Benj Haisch, this thorough hands-on video puts the SL3-P through real-world use, including wedding video work, backyard sports testing, and low-light dance floor shooting. Haisch has been openly critical of the SL series for a while, particularly around autofocus, so his take carries some weight when he says this camera changes his view. He ran it with the Leica 24-70mm f/2.8 as the primary autofocus lens and found hit rates on moving subjects, including a kid sprinting in a backyard, to be more than acceptable. His read is that this is the best-focusing camera Leica has built to date, and that he'd be comfortable shooting a full wedding with it without feeling like he was fighting the system.

On the video side, the SL3-P shoots 8K open gate, 6K open gate, and 4K at up to 120 frames per second. Haisch used 6.4K open gate at 23.98 fps and 6K 60p extensively during a wedding shoot, and the footage holds up well even at 3,200 ISO on a dark dance floor with only a small off-camera light for fill. The burst shooting tells a different story: 40 frames per second is available, but you're capped at 70 frames total on the electronic shutter before the buffer needs to clear, and at 14-bit you're limited to slower burst rates. Rolling shutter shows up on fast lateral motion, which Haisch demonstrates clearly with a plastic bat swing that visibly warps in the frame.

One of the more practical highlights Haisch covers is the menu system. Leica built a filtering approach into the video settings, where selecting a sensor format or frame rate narrows down the remaining options automatically, so you're never scrolling through combinations that don't apply. He also points out that long-pressing any button on the camera brings up an option to remap it on the spot, skipping the customization menu entirely. He had the camera configured to his preferred video profiles in under five minutes. The build quality gets real attention too: the SL3-P is IP54 weather-rated, fills the hand without needing an add-on grip, and feels closer in heft and solidity to a medium format body than a typical full frame mirrorless.

The elephant in the room, which Haisch addresses directly, is how closely the SL3-P resembles the Panasonic Lumix S1R II in specs, including sensor resolution and video capabilities, while costing roughly twice as much. His reasoning on that tradeoff, along with the rest of the autofocus breakdown, video sample analysis, and his final verdict on who this camera actually makes sense for, is all in the video.
