Leica SL sensor review: Best-performing Leica to date 2019


Specifications and Features

as, and now with the introduction of the new full-frame mirrorless Leica SL (Type 601), the company should hope they finally have a platform Is for the legendary R-system of the manufacturer's SLR lens. In fact, the Leica SL has been introduced with mount adapters for M-, S-, and R-series lenses, and while it appears that the Leica SL has a new lens mount, it is actually on the same mount. is used to. Leica T.

 Although that camera was an APS-C format model, the T-series lens can be used on the Leica SL in crop mode. As a multi-stage camera, then, the Leica SL seems particularly well suited.

 In addition to the full-frame 24-MPX CMOS sensor, which avoids an AA filter to maximize potential expansion in the imaging range, and the Maestro II processor with sensitivity from  - 4.4 million-dot display with magnification of 0.8 million, which is larger than any pro-grade DSLR from Canon or Nikon.

 The autofocus is what the Leica L-mount lens is saying (so far limited to just one model, optically-stabilized Wario-Elmarit 24-90mm f2.8-4 ASPH $ 4950) made up of 49-point contrast detection system, But the T-series lens can also be focused automatically.

Leica SL sensorMeasurements: The best-performing Leica ever

The latest addition of Leica undergoing testing in our labs achieved an overall DxOMark score of 88 points, which is just three points higher than Leica Q.

 The Leica SL realized an excellent score of 25 bits for color sensitivity, a solid 13.4 EV range at base ISO, and a good one when compared to a low-light ISO score of 1821 ISO. It stops at Leica Q about a -0.25 and is indistinguishable from Lyca M.

Comparison 1: Leica SL (Type 601) vs Leica Q (Type 116) vs Leica M (Type 240): Excellent ISO at high ISO.

Compared to its siblings, the $ 7250 rangefinder Leica M and the $ 4250 fixed-lens compact Leica Q, the new Leica SL gains a subsequent three-digit incremental edge over the 21% Leica M. and overall overall improvement. Is too much.

The Leica Q is achieved by a lower base ISO setting (ISO50) and a lower SNR, which in turn accounts for a color sensitivity of 25 bits. In fact, all three colors share the same results of sensitivity when they overlap in ISO sensitivity. In terms of dynamic range, it is slightly different, with Leica SL and Leica Q sharing similar results.

 Both models show better dynamic range over the Leica M at higher ISOs, but at the base, all three share a similar 13-stop dynamic range. Both the Leica SL and Leica Q have relative ISO attacks in comparison, and with this, a boost in the dynamic range at ISO400 which is roughly equivalent to +2 EV gain over ISO1600. Despite the low-noise floor, low-light scores are comparable, although the Leica Q has a slight advantage in our tests, which is equivalent to just +0.25 eV.

Comparison 2: Leica SL (Type 601) vs Sony A7 II vs Nikon D750: Close to leading-edge mobility

Comparing Leica SL with two rivals that are capable of delivering a 16-bit TIFF file of the same size, the Sony A7 II and Nikon D750, Leica performs very competitively. In fact, overall it is close to Sony and not far behind Nikon, which has the best-performing full-frame 24-MPP sensor in our database.

In terms of color depth, the Leica SL is more or less the same for both ISO ranges, although Leica's lower base ISO of 50 helps to some extent in its summary score. This is not to say that it does not have the highest-measured color sensitivity, but as always, it pays to look at the results presented in our graph.

For the dynamic range, the Leica SL practically matches the Sony A7 II, though Sony has about 0.5-stop additional dynamic range at ISO100 and a +0.3 EV gain in low light. But this is only a minor lead, and the additional dynamic range is not noticeable on other settings.

Nikon has extracted the most from its sensors, and the Nikon D610 ranks as class-leading on the D750 as well as 24-Mpix. Still, with only 5 points overall, Leica is closing the gap that once existed in sensor dynamics between higher-range cameras and more mainstream models.

While the color depth is comparable to the Leica SL, the Nikon D750 has only one stop (+ 1.1EV) wide dynamic range at ISO100, which is below the IS200. From ISO400, the gain in the dynamic range has been reduced, although Nikon hovers around the +0.5 EV lead in our low-light score.
The conclusion

Although Leiko Q's sensor performance improves on the direction Leica indicated, the Leica SL sensor does. Such improvement can occur only in a few small ways, but it is quantitative. With several still surpassing high-end DSLRs with impressive capability, and access to Leica's vast range of top-drawer optics with a range of optional adapters, the Leica SL is a compelling option, especially for those.

Who already owns a number of Leica. Lens. The Leica SL is not cheap, but engineering never happens at this level again. Compared to the Lyca M, there is not much of it — indoors, it is also cheaper than a new M-P for $ 7950 and before taking care of the extra $ 570 for the Leica Visflex EVF2. Given the benefits of the built-in viewfinder for focusing, especially off-center, SL may also be a better bet.
