Retiring previous M9 and M9 P versions this latest model – known simply as the Leica M, sits alongside the Leica M-E Typ 220 as the two full frame cameras in the German manufacturer’s renowned M series. With a list price of $6950 (body only), streamlined functionality and rangefinder viewfinders Leica cameras are unusual in the digital era but they continue to hold reverence with some photojournalists.
Quality engineering using brass and magnesium combined with simple controls and petite proportions make the M solid as well as portable and quick for reportage photographers. The rangefinder style of composition provides a rough indication of framing using guidelines in the viewfinder that adjust as you change lens. This is done via a sensor in the body to read the lens profile and allows the image processor to apply lens-based corrections as files are saved.
Compatible with both M mount as well as Leica R lenses via the $310 R Adapter M, there’s a wide choice of high quality Leica optics available for the M, but it only offers manual focus. The new 3.0in 920k LCD does feature live view for more precise framing however and makes shooting with macro or telephoto lenses a realistic possibility. Live view also offers a 10x magnification for precise manual focus.
Despite remaining true to simplicity this latest model does incorporate a few updated specs such as HD video, a 100 – 6400 ISO range, 3fps burst shooting and compatibility with the $465 EVF2 viewfinder, which plugs into the hot shoe, but there’s no built-in flash. Lets find out if the new 24-megapixel CMOS sensor can catch up with the latest DSLR competition.
Leica M: New 24-megapixel CMOS sensor significantly improves image quality
Achieving an overall DxOMark Sensor Score of 84 the Leica M ranks 11th for all sensors on database and 8th overall for full frame cameras. Ahead in the full frame category remain the latest generations of full frame Nikon and Sony cameras but the M’s new CMOS sensor does just nudge out Canon DSLRs. Its individual category rankings are all down on 11th place however making it a good all rounder without a particular strong point.
A Portrait (Color Depth) score of 24 bits places the Leica M 21st, a Landscape (Dynamic Range) score of 13.3 Evs is 17th and its Sports (Low light ISO) is a bit off the pace with the best in this class with a rating of 1860 ISO placing it 13th.
During testing we did also observe under certain lighting conditions the problem of colour shading, which was low but noticeable when using certain lenses. Overall however though this is a significant improvement in image quality for the Leica M thatseries and puts itLeica back in the hunt with the full frame competition.
Note: Since testing the M running firmware version 184.108.40.206 Leica have updated to version 220.127.116.11, which provides a small improvement for video quality, lens support and stability.
Leica M-E Typ 220 Vs Leica M Typ 240 Vs Leica M9 P: A big step forward for the latest M
The 18Mp CCD previously used in Leica M rangefinders hasn’t fared well in our tests ranking towards the bottom for full frame sensors. The new 24Mp CMOS model is a big improvement however boasting 6 million more pixels than its predecessor and delivering a 1 Stop improvement in image quality, too. With a +1 Stop improvement for both Color Depth and ISO, as well as an impressive +1.6 Stops better Dynamic Range, it seems switching to a CMOS sensor was certainly a good move for Leica. It’s interesting to note too that no RAW smoothing is applied to files from the new model, as was previously the case from ISO 400 on earlier versions.
Leica M Typ 240 Vs Sony RX-1 Vs Nikon D800: Leica M remains behind the best new sensors
Two of the best full frame sensors we’ve tested in the fixed lens Sony RX1 and Nikon D800 DSLR offer a +2/3rds of a Stop image quality overall compared to the Leica M. Drill down into the different categories and the superior RX1 and D800 sensors deliver + 2/3rds of a Stop better Color Depth and Low-Light ISO performance. The Leica M’s measured base ISO of 134 compared to ISO 81 and ISO 74 for the RX1 and D800 respectively mean the Sony and Nikon cameras have an immediate advantage and deliver +1 Stop improved Dynamic Range overall with scores of 14.3 (RX1), 14.4 Evs (D800) and 13.3Evs (M). As sensitivity is increased on all three cameras Dynamic Range drops at roughly the same trajectory up to ISO800 where the Leica M takes a further dip. The impact of this is good Dynamic Range of 10Evs and over is only achievable on Leica M up to ISO1600, while the RX1 / D800 are good until ISO 3200 and these better sensors offer the same Dynamic Range at ISO 25600 as Leica M at its maximum sensitivity of ISO 6400.
Leica M Typ 240 Vs Nikon D4 Vs Canon EOS 1Dx: Leica M catching up the sensor performance in top of the range DSLRs
Compared to the full frame sensor in Canon’s flagship DSLR, the 1Dx, the Leica M just wins overall with 84 points to 82. For Color Depth there’s little in it with 24 bits for the M compared to 23.8 bits for the 1Dx, so it’s left to Dynamic Range and Low-light ISO to separate them. At base ISO sensitivities the Leica M offers significantly improved Dynamic Range +1.5 Stop better than the 1Dx, although this changes quickly as sensitivity is increased.
While the 1Dx delivers consistently good Dynamic Range of around 11.8Evs up to ISO 800 the Leica M performance drops markedly as sensitivity is increased and by ISO 800 the two cameras are the same. The trend persists past ISO 800 too where the Leica M’s Color Sensitivity continues to drop rapidly and the 1Dx offers better Dynamic Range at ISO 25600 than the Leica M at ISO 6400.
Nikon’s top end DSLR the D4 ranks 1/3rd Stop better than the Leica M overall scoring 89 points compared to 84. The D4 is also ½ Stop better for Color Sensitivity at base ISO with 24.7 bits to 24 bits, but as the Leica M’s performance takes a dip as ISO sensitivity is increased the D4 offers +2/3rds of a Stop Color Sensitivity at ISO 1600 compared to the Leica M at the same sensitivity. While the D4 and the Leica M have similar Dynamic Range at base ISO sensitivity of 13.3Evs (M) to 13.1Evs (D4) the same pattern emerges as sensitivity is increased, so while good Dynamic Range of +10Evs is possible on the Leica M up to around ISO 800 the D4 delivers the same results up to ISO 3200.
No doubt you’ve picked up on the pattern here that while the Leica M can deliver comparable results at base ISO it struggles at higher sensitivities. With a DxOMark Low-light ISO score of 1860 ISO (M) compared to 2965 ISO (D4) and 2786 ISO (1Dx) the rangefinder offers around -1 Stop ISO performance compared to these flagship DSLRs.
Leica M: CMOS sensor provides a welcome boost for Leica M image quality scores
Featuring a new higher resolution sensor and updated functionality expectations are high for the new Leica M and it doesn’t disappoint. Although remaining true to their ‘no gimmicks’ approach the addition of an improved LCD screen with live view, as well as the increased ISO sensitivity range are welcome additions that update Leica’s digital rangefinder for the modern era.
The latest 24-megapixel CMOS sensor offers not only six million extra pixels but DxOMark’s Sensor Scores indicate a +1 Stop improvement in overall image quality compared to the previous 18Mp CCD sensor. As well as offering more consistent Color Sensitivity across the ISO range there’s also an impressive extra +1.6 Stops boost for Dynamic Range and its low-light ISO scores are improved too, again beating previous versions by around +1 Stop.
So a big step in the right direction although the new sensor doesn’t quite match the heights of the best sensors DxOMark have tested or those of flagship DSLRs. Compared to the best sensors the Leica M is a little off the pace with the Sony RX1 and Nikon D800 boasting around +1 Stop better image quality overall.
Against the Nikon D4 and Canon 1Dx the overall scores indicate the Leica M is either better or not far off in terms of Color Sensitivity and Dynamic Range. These overall scores are a little misleading however as image quality on the M drops quickly as ISO sensitivity is increased compared to this DSLR competition, which deliver a more consistent performance up to ISO 3200.
Nonetheless a welcome improvement in image quality demonstrates Leica made a wise choice switching to a CMOS sensor. If you’re after a Leica digital rangefinder and your budget can stretch to $6950 the new M offers better image quality, features and functions compared to the $5450 M-E Typ 220.
