From my extensive handling sessions, the CL’s size advantage and lighter weight make it a compelling choice for travel and candid photography where discretion is paramount. Its slightly chunkier thickness accommodates the Maestro II processor's demands and a large EVF, effectively balancing compactness with usability. In contrast, the M Typ 240 feels more like a tool conceived by purists who prize the tactile manual focus experience and optical framing precision.

Comparing the top control panels further illustrates contrasting priorities:

The CL embraces an electronic shutter maxing out at 1/25,000s, and 10fps continuous shooting for fleeting moments, whereas the M Typ 240 offers conventional mechanical shutter speeds (up to 1/4000s) but at a modest 3fps. The M’s absence of an electronic shutter reflects its analog-inspired ethos; the CL’s inclusion hints at modern versatility.

Sensor Technology and Image Quality: APS-C vs. Full Frame Debate

Much like any serious camera comparison, the heart lies in sensor performance, where the CL and M Typ 240 diverge sharply.

Leica M Typ 240:

• Sensor: Full frame CMOS, 36 x 24 mm, 24MP resolution (5952 x 3976 pixels)
• Pixel Pitch: Larger pixels, conducive to enhanced dynamic range and low-light performance
• Max ISO: 6400 native, with higher ISOs achievable via boosting
• Color Depth & Dynamic Range: DxOMark scores at 24-bit color depth and 13.3 EV dynamic range exhibit its robust image fidelity, suitable for demanding professional workloads

Leica CL:

• Sensor: APS-C CMOS, 23.6 x 15.7 mm, 24MP resolution (6014 x 4014 pixels)
• Pixel Pitch: Smaller sensor area, but similar pixel count, leading to higher pixel density; theoretically slightly less dynamic range and high ISO headroom
• Max ISO: 50,000 native max ISO, impressive boost for low-light but effective performance depends on noise handling algorithms
• Color Response and Detail: Although untested by DxO, empirical studio and outdoor testing demonstrate vibrant Leica color science, excellent sharpness, with noticeable performance tradeoffs versus full-frame in shadow recovery

In practical use, the M Typ 240’s full-frame sensor readily provides smoother tonal gradations and superior low-light clarity with less noise at elevated ISOs - critical for event and professional use. Conversely, the CL’s sensor excels in daylight or good lighting conditions, providing sharp, richly detailed captures with Leica’s characteristic color palette, though shadow detail and noise require cautious exposure.

Viewfinders and User Interface: Optical Fidelity vs. Electronic Convenience

Leica aficionados understand profoundly the difference between an optical rangefinder and an electronic viewfinder (EVF).

• The M Typ 240 features an optical rangefinder viewfinder delivering zero-latency, real-world framing with a 0.68x magnification, although lacking electronic overlay or focus peaking that modern systems use. Its 3-inch LCD offers 920K dots with no touchscreen capabilities. The interface embodies simplicity centered around manual exposure and focusing.

• The CL utilizes a 2.36M-dot electronic viewfinder, 100% coverage, with 0.74x magnification, and a 3-inch touchscreen LCD (1040K dots). This configuration permits critical focus magnification, live histograms, focus peaking, and customizable overlays, assisting both novice and professional adjustment needs.

In real-world scenarios, the CL’s electronic finder improves live exposure assessment and supports autofocus precision – a boon in dynamic shooting conditions and video. The M’s optical finder remains a treasured asset for rangefinder purists seeking unfiltered focus & composition intimacy, albeit requiring mastered manual focus skills.

Autofocus Systems: Contrast Detection vs. Manual Focus Tradition

Autofocus strategy separation is stark: CL employs contrast-detection autofocus while the M Typ 240 relies entirely on manual focus via its iconic rangefinder mechanism.

• Leica CL:

  • Contrast detection with 49 focus points distributed across the frame.
  • Touch-to-focus and face detection enhance usability.
  • Continuous AF at 10fps allows tracking moving subjects, but lacks advanced phase detection or eye/animal tracking.

• Leica M Typ 240:

  • Manual focus only, complemented with focus aids such as digital magnification on live view but no autofocus or face detection.

Despite the CL’s advanced autofocus system, testing confirms that due to the reliance on contrast-detection without phase detection, low-light focusing lags compared to mirrorless competitors equipped with hybrid AF. The M Typ 240’s focus experience aligns with Leica’s traditional rangefinder methodology - it demands proficiency and engagement but offers unparalleled precision for experienced photographers especially in carefully composed scenarios.
