What is it?

That 44MP BSI CMOS sensor will be familiar to anyone that’s been following Panasonic’s recent launches.

Thus far, Leica has produced high-resolution SL models and high-speed SL-S versions. The SL-P appears to be something of an attempt to merge the two lines, offering both high speed and high resolution.

The result is something akin to Sony’s recent a7R VI or, perhaps more pertinently, the Panasonic S1RII: not an out-and-out sports camera but more a studio and landscape camera that’s happy to venture further afield. That Panasonic comparison is unavoidable as the 44MP, 40fps headline spec is shared between both cameras, as are their processors, even if the branding of them differs.

However, our experience of the SL3-P and the S1RII reminded us of how different you can make two cameras, even if you start with many of the same components and have similar destinations in mind.

Leica talks a good game about building cameras that last, and that’s immediately apparent in the feel and heft of the SL3-P. But what’s really striking is how few control points the Leica seems to have. That minimalism, honing the camera down to its core functions and little more extends to the menus and interface, meaning it gives a very different experience to the Panasonic. Or, indeed, any other mainstream camera.

How it compares

Although it offers both high speed and high resolution, the SL3-P doesn’t match the do-everything levels of capability of the Nikon Z8 and Canon EOS R5 II, with their stacked CMOS sensors. Instead it’s closer in ethos to the Sony a7R VI or, perhaps unsurprisingly, the Panasonic S1RII, essentially delivering a studio and landscape camera that isn’t scared of a little action, rather than a camera you might pick for sports work.

We’ve also compared it here to the SL3, which offers higher resolution but less speed, if absolute image quality is more important to you than the added speed.

It probably shouldn’t come as a surprise to find that the SL3-P’s specs are a very close match for those of the S1RII. The differences between the two cameras aren’t something readily captured in a specs table.

The original SL3 offers a slight boost in resolution capture but at the cost of a lot of the new camera’s flexibility. Sony’s a7R VI offers both though: higher resolution and competitively fast shooting with excellent autofocus and slightly wider dynamic range. It’s hard to imagine how two user interfaces and user experiences could be more different, for two cameras ultimately trying to do the same thing, though.

Body and handing

The SL3-P’s design is as simple and solid as the huge sans serif branding across its viewfinder hump. And with a vague sense that this is how it’s always been.

The SL3-P uses the same body as the existing SL3 models: a solid, angular block of a thing with a few large control points and a substantial grip to wrap your hand around. The Leica branding across the viewfinder hump is so beautifully proportioned that it’s easy to assume that this series (and, perhaps, a series of film cameras before it), have always looked this way. So it was a shock to see the original SL in the company’s archives and see how far the design has evolved.

There are two buttons on the front of the camera, two on the top and one on the back, none of which have marked functions. Instead they can be re-programmed with a long press. In addition there are three marked buttons on the back of the camera: Play, Fn and Menu.

Then there are the three large command dials: one towards the front of the top plate, one protruding from the rear of the right shoulder and a third on the top left of the camera (which I kept forgetting about, as it’s such an unorthodox place to find one).

Beyond this there’s a small rubber joystick on the back of the camera, and that’s about it. Relatively few control points and still fewer dedicated ones. No switches for focus mode or AF area, not even the seemingly obligatory stills/movie switch: that’s controlled by swiping left or right on the rear screen.

Rather than making you dig through an incredibly long list of formats, the SL3-P makes it easy to filter down to the video modes that fit your shooting scenario.

We’ll touch more on the user interface in the ‘In use’ section of the review, but Leica is continuing to refine the rather elegant and focused interface it introduced in the SL3. For instance, in this latest camera, the company has re-worked the way you select a video mode: letting you select the parameters that are most important to you: frame rate, resolution, codec, etc, then filtering down the available list from a seemingly unmanageable 193 down to the handful that fit your requirements. It sounds obvious once you’ve seen it done, but it’s cleaner and simpler than most cameras we use.

Viewfinder and screen

The SL3-P has the same viewfinder as the other SL3 models: a 5.76M dot OLED panel (1600 x 1200px) with 0.76x magnification and a 21mm eyepoint. A large circular rubber cushion makes the camera comfortable to use if you wear glasses and there’s a -4 to +2 diopter adjuster set behind that cushion.

The rear screen is a 2.33M dot (1080 x 720px) panel mounted on a tilt up/down mechanism.

Ports

The SL3-P has the same port arrangement as its sister models, with 3.5mm headphone and mic sockets and a full-sized HDMI socket under a large, rubber flap on the left flank of the camera. Below these is a USB-C socket that can be used for data transfer (10Gbps), tethering (including to an iPhone) or charging.

Battery

As has become standard for Leica, the base of the battery includes the outer surface of the camera. There’s a sprung silver lever on the base to release the battery and a stepped latch to prevent it just dropping onto the floor when you do.

The camera uses the same BP-SCL6 battery as its siblings: a 15.8Wh unit that powers the camera to a rating of 383 shots per charge, when tested to the CIPA protocol. As always, this tends to significantly under-represent the actual number of shots you can expect to get, but a rating of nearly 400 shots per charge is the sort of number that should means an enthusiast photographer rarely has to worry about topping-up on a day’s shooting. It’s only intensive shooting such a weddings, or anything involving a mixture of video and stills that are likely to call for you to have a spare to hand.

Autofocus

The Leica’s autofocus behavior is as innovative and unconventional as the rest of the UI.

The camera has three AF area modes, but offers more than three AF areas. The first is called “Spot / Field,” the second is called “Multi-Field / Zone” and the last is called Tracking.

There are three AF area options available, but two of them represent a series of different AF area modes.

The clue is in the forward slashes. Spot / Field lets you select a single AF point of various sizes, while Multi-Field / Zone lets you choose between an adjustable AF zone and all-area AF, where the camera selects a subject from anywhere within the frame. Once you’ve chosen an AF zone mode, you can adjust it by pressing the AF area on your rear screen or long-pressing anywhere on the live preview. This then lets you use the rear dial to adjust the focus area size.

You can’t adjust the size of the tracking AF target but you can, in the menus, reconfigure it so it doesn’t keep jumping back to the center of the screen.

Like Panasonic’s recent cameras, the camera will track recognized subjects when you have subject recognition turned on, but won’t track non-recognized subjects at all. So you’ll need to turn subject recognition on and off depending on what you’re trying to photograph. We’d definitely recommend configuring a button to do this.

By default, the camera’s Tracking AF mode gives you a small rectangle that resets to the center of the frame at the end of each burst. However, while you can’t change the size of the initial target, you can configure the tracking target to revert to wherever you last triggered it. So, for instance, if you want to track a car down through a series of curves, across your frame, then have the camera jump back to where the next car is likely to arrive, you can.

In use

One of the Leica’s most compelling aspects isn’t something you can see from product photos or interpret from the spec sheets: the user interface.

The SL3-P uses the latest iteration of the back-to-basics interface Leica has been refining over the past few years.

Pressing the menu button brings up this status panel, which can be customized with a long press of any of the virtual buttons. You can even customize the list of available options, to make selection faster. Pressing the menu button again takes you into the main menu, which is impressively concise for a modern camera.

At its heart, it’s designed around putting the key photographic parameters at your fingertips and minimizing the extent of, and need for, menu options. For instance, holding down a customizable button or long-pressing any of the on-screen icons brings up a list of other functions you can assign to it. In fact one of the few options present in the main menu is one to filter-down which options are presented to you, when you long-press a control point to customize its function.

The result is an interface very focused on the fundamental settings of photography. It affords you the luxury of just ignoring what’s going on in the interface, much of the time, and just letting you concentrate on the settings assigned to the two big dials, and what you’re seeing in your viewfinder.

The Play, Fn and Menu buttons on the back of the camera are the only ones with marked functions: the rest are designed to be configured (and reconfigured) to suit your shooting style and preferences.

This minimalist approach extends to the body and its control points, too, with a smattering of custom buttons, a joystick and three large, solid-feeling command dials being your points of contact. It’s remarkable how few dedicated control points there are and while, for my shooting, I found myself sometimes wishing for an AF mode selector, with a little work it’s very likely that you can set the camera up in a way you find very quick and easy to work with.

Because it’s such a different way of working, the interface takes a little bit of getting used to, though. It rewards you for taking the time to adjust to its design philosophy. One aspect of which is learning to save your setup as a user profile, or risk discovering that selecting the default profile erases any customization you’ve started applying.

It’s also worth recognizing what is and isn’t included in these profiles. Exposure mode is, but specific exposure settings aren’t, so my attempt to build a profile for freezing the action and another one, with a slower shutter speed, for panning ended up being unsuccessful. Likewise, it’s worth carefully planning your profiles before saving them: I thought it would be handy to define a custom button to switch between profiles. Which was great until I pressed the button and switched to a profile with different custom buttons settings, so couldn’t get back.

Overall it works very well, though, giving a very photo-focused shooting experience where, for all the cleverness that modern cameras have brought, you end up remembering that the only things that really matter are shutter speed, aperture value, composition and where you’re going to focus.

Video

Despite us saying that the SL3-P has a very photo-focused interface, it’s probably better to say that it’s a very exposure-focused. Swipe left on the camera’s settings panel and you get a similar but now video-centric display, with yellow, rather than red accents.

The SL3 offers an incredible range of video modes: 157 in total. These range from 8K open-gate capture, that uses the full extent of the sensor, via 8K in either 1.89:1 or 16:9 aspect ratios and on to 4K capture, again with a choice of aspect ratios. But the camera also offers a selection of other resolutions for each of these capture regions, letting you strike a balance between resolution capture and speed.

Like Panasonic’s S1RII, the SL3-P doesn’t quite have enough pixels to capture DCI 8K (8192 x 4320px) footage so instead outputs 8132 x 4288px footage. UHD 8K is no problem, though, so you can also select the more conventional 7680 x 4320 resolution, if you prefer.

As you’d expect of a modern camera, you get the choice of 10-bit Log or HLG, or 8-bit if you don’t plan to color grade, and you’re targeting SDR displays.

Video options:

As with the Panasonic S1RII, the SL3-P has a Dynamic Range Expansion mode in video, which reads each exposure in both low conversion gain mode for maximum highlight capture and in high conversion gain mode, for cleaner shadows, and combines the two, to boost DR.

This is available in any resolution mode but only at frame rates up to 30p. In each case it increases the readout rate by around 33%. So, for instance, the UHD 8K/24 mode increases from 23.9ms to 31.9ms.

Initial impressions

The Leica SL3-P is the fastest-shooting camera Leica has ever made and should, in principle, be the only SL model they need to persist with. It offers an awful lot of what the SL3 offers, in terms of resolution, and it outperforms the more speed-focused SL3-S.

The subject recognition AF performs impressively well: finding subjects very quickly and following them well (especially when it’s a subject the camera has been trained to recognize). Just as the user interface as a whole takes some getting used to, it’s worth digging around in the menus and familiarizing yourself with the SL3-P’s AF logic before you go out shooting. Without an instruction manual it wasn’t obvious that Leica had grouped its AF area modes, or how to switch between them, nor that you can override the camera’s default behaviour when it comes to AF tracking.

Some issues you can’t overcome, though. The sensor is fast, but it’s not as quick as the best stacked CMOS sensors. So the camera will start showing a slideshow of the images you’ve just shot, when you’re shooting at its fastest rates, making it very difficult to keep pace with the action. Similarly, we were advised to shoot Raw-only and to disengage Content Credentials, to get the best performance.

Rolling shutter can become visible if the camera or subject moves too quickly. The camera makes clear whether it’s shooting in 12 or 14-bit readout mode, which significantly affects the rolling shutter rate.

And, even with that done, the camera’s approximately 20ms (1/5 sec) readout rates in 12-bit mode mean that rolling shutter will be apparent if you’re trying to follow really fast action.

In this respect it’s a lot like the Sony a7R VI we recently reviewed: very fast for a high-res studio/landscape camera, meaning it’ll handle itself very confidently in a much broader range of circumstances than that. It’s not quite the high-res, high-speed all-rounder that Canon’s EOS R5 II and Nikon Z8 are, but it’ll still be more than enough camera for a very broad range of photographers, taking a very broad range of photos.

The challenge, as ever with Leica, is the price. It’s a beautifully built object, constructed in Portugal and Germany, that wears the Leica name and is likely to sell in relatively small numbers, when compared to the volumes of the large Japanese manufacturers. As such, the price is high.

For that money you get the fruits of some very clever design work, in a body that feels like it’s designed to last decades. However, parts availability and the continued march of technology (we can already see that sensors and AF will continue to get faster), will make it difficult to match the sense of longevity that a Leica film camera gave you. So, as always, part of the calculus comes down to: how important are those five letters to you?
