First Impressions: Size, Build, and Usability

Handling and Ergonomics

At first glance, the newer Nikon D7500 offers a more contemporary and ergonomically refined body, but it’s important to understand the context of each design.

The Leica Digilux 3, released in 2006, is a mid-size SLR featuring a traditional SLR design with a relatively compact footprint for its time. Weighing 606 grams and measuring 146x87x77 mm, it’s reasonably portable but lacks some modern conveniences. Notably, it has a fixed 2.5-inch, low-resolution LCD and no touchscreen, live view modes are minimal, and its user interface is intentionally minimalistic - typical for Leica’s philosophy emphasizing direct control and simplicity.

The Nikon D7500, launched over a decade later in 2017, tips the scales at 720 grams but offers a more substantial grip, tilt-angle 3.2-inch touchscreen LCD with significantly higher resolution (922k dots), and modern live view with advanced autofocus. It measures 136x104x73 mm - shorter but noticeably thicker and heavier than the Digilux 3.

Control Layout and Intuitiveness

From the top view, the D7500 showcases Nikon’s signature exposure-compensation dial, mode selector, and customizable buttons - providing immediate tactile access to settings enthusiasts demand. Buttons are logically placed and illuminated, facilitating easy use in dim conditions.

Conversely, the Leica Digilux 3 takes a minimalist approach. It has fewer buttons and dials, reflecting an era where simplicity was prized and many advanced functions were manual. Its optical pentamirror viewfinder has 95% frame coverage and 0.47x magnification, which feels restrictive compared to the D7500’s bright pentaprism with 100% coverage and 0.63x magnification - significant for critical reframing and composition.

Summary: The D7500 excels ergonomically and functionally for the modern photographer, while the Digilux 3 appeals to users who prefer a simpler, classic tactile experience.

The Heart of the Camera: Sensor Technology and Image Quality

Sensor Specs and Performance

The Leica Digilux 3 is equipped with a 7-megapixel Four Thirds CMOS sensor measuring 17.3x13 mm - a relatively small sensor by today’s standards. Its maximum native ISO is 1600, with no extended ISO, and it features a traditional anti-alias filter. The camera supports RAW files, allowing some latitude in post-processing, but dynamic range and color depth inevitably fall short of modern sensors.

In contrast, the Nikon D7500 boasts a 21.0-megapixel APS-C CMOS sensor (23.5x15.7 mm), a larger area which correlates with improved low-light sensitivity, less noise, and better overall image quality. Nikon’s omission of the anti-aliasing filter aids in resolving finer detail at the expense of potential moiré in some scenarios. A staggering maximum native ISO of 51200, extendable up to ISO 1,640,000 (boosted), provides remarkable flexibility in varied lighting.

Testing Results:
During my tests shooting both cameras under controlled lab conditions and in field environments, the D7500 consistently delivered richer, cleaner images with higher dynamic range. Skin tones appeared more natural and subtly gradated, especially in JPEG outputs. The Digilux 3 images, while retaining a distinct vintage character beloved by Leica enthusiasts, struggled in low light and showed more noticeable noise and color shifts.

Autofocus and Shooting Speed: Precision and Responsiveness

Autofocus Systems Compared

The Digilux 3 employs an early phase-detection system with 3 focus points - adequate for static subjects but limited for fast-moving or complex scenes. It lacks face or eye detection and offers no live view focus assistance. Autofocus performance was acceptable during my portrait sessions but struggled tracking wildlife or sports subjects.

The D7500’s 51-point multi-CAM autofocus system, including 15 cross-type points, is vastly superior. It incorporates face detection, continuous tracking, and supports autofocus in live view via contrast-detection. During wildlife and sports tracking tests, I found it fast, accurate, and reliable, even under challenging light.

Continuous Shooting and Shutter Speeds

Continuous burst modes greatly influence shooting sports or wildlife. The Digilux 3 offers a modest 3 frames per second (fps) shooting rate, capped by a max shutter speed of 1/2000 s. That’s quick enough for casual activities but limiting for capturing high action.

The Nikon D7500 pushes to 8 fps and can reach shutter speeds as fast as 1/8000 s, enabling freeze-frame shots of fast subjects. Additionally, its flash sync speed is 1/250 s compared to the Digilux 3’s slower 1/160 s limit - crucial when using fill flash outdoors.

Viewfinding and LCD Interface: Composing and Reviewing Images

Optical Viewfinder Experience

The Digilux 3’s pentamirror viewfinder covers 95% of the frame, which means what you see is slightly less than what the sensor captures. Magnification sits at 0.47x, making the viewfinder dimmer and smaller than modern standards. While this may appeal to traditionalists familiar with rangefinder-style framing, it can be restrictive for critical manual focus work.

The D7500 sports a bright pentaprism with 100% coverage and 0.63x magnification; this means what you see matches exactly what you get in the final photo - a decisive advantage for precision framing and manual focus.

LCD Screen and Live View

Reviewing images and navigating menus is enjoyable on the Nikon’s large, tilting touchscreen LCD. Responsiveness is snappy, and the interface benefits from years of usability refinement.

By contrast, the Digilux 3’s fixed 2.5-inch LCD with just 207k dots resolution is more of a legacy feature. Live view is basic and non-touch, making menu navigation slower and less intuitive.

Lens Ecosystem: Flexibility and Creative Potential

The Leica Digilux 3’s Micro Four Thirds mount is a compact system with about 45 lenses available. Though Leica lenses are renowned for optical quality and character, the selection is limited compared to Nikon’s legacy.

The D7500 uses the Nikon F mount, which boasts an extensive lens ecosystem exceeding 300 options, from ultra-wide to super-telephoto, including many affordable third-party lenses. This enables photographers to cover virtually any genre or specialty without compromise.

Moreover, the D7500 features in-body vibration reduction (IBIS) image stabilization, facilitating sharper handheld shots even with non-stabilized glass. The Digilux 3 lacks any stabilization, meaning you must rely entirely on lens stabilization or tripod use.

Weather Sealing and Durability: Can They Take a Beating?

The Nikon D7500 has partial environmental sealing against dust and moisture, making it more resilient for fieldwork in challenging environments. I have personally shot in rain and dusty conditions with it without issues.

The Digilux 3 offers no weather sealing and should be treated more delicately. Its older build is solid but not designed for rugged use.

Battery Life and Storage: Practical Considerations for Extended Shoots

Battery endurance is crucial, especially for travel, wildlife, or event photographers.

• Digilux 3: Battery life specs aren’t well-documented, but given its age and design, expect limited shots per charge - likely under 300 images.
• Nikon D7500: Rated for an impressive 950 shots per charge, tested with the EN-EL15a battery.

Storage-wise, both cameras take standard SD cards, but the D7500 supports modern SDXC formats with larger capacities and faster write speeds.

Video Capabilities: Modern Needs Versus Legacy Limitations

Videographers will find the Nikon D7500 vastly superior.

• Nikon D7500 offers 4K UHD recording at 30p, with 144 Mbps bitrate and uncompressed audio via mic input. It also supports external headphone monitoring through a dedicated port.
• Leica Digilux 3 has no video recording capabilities.

This makes the D7500 suitable for hybrid shooters needing high-quality video and audio integration, while the Digilux 3 is strictly a stills camera.
