The Panasonic LX7 is a pocketable, fast-aperture compact that pushes the limits of small sensors, while the Pentax K-r is a traditional DSLR equipped for broader versatility, paired with a larger APS-C sensor and the flexibility of interchangeable lenses.
As you can see from this image, the LX7 is noticeably smaller and lighter, favoring portability. Meanwhile, the K-r offers a bulkier grip and more substantial body typical of DSLRs, conducive to longer shooting sessions with heavier lenses.
Sensor and Image Quality: The Heart of the Matter
Sensor Size and Resolution Impact
The first major distinction is sensor size. The LX7’s 1/1.7" sensor measures just 7.44 by 5.58 mm, delivering 10 megapixels, while the Pentax K-r’s APS-C sensor (about 14.5x larger) produces 12 MP. This sensor size body drastically improves light gathering, noise performance, depth of field control, and dynamic range.
During my tests, the Pentax’s larger sensor consistently yielded cleaner images at higher ISO settings, a broader dynamic range, and superior color fidelity. DXOMark's overall score - 72 for the K-r against 50 for the LX7 - aligns with these observations: the K-r offers better low-light ISO performance (755 vs. 147), deeper color depth, and wider dynamic range for capturing subtle tonal gradations.
For portrait and landscape shooters, this difference translates to better skin tones, fine detail retention, and shadow recovery from RAW files on the Pentax. The LX7’s sensor performs well in good daylight but struggles to hold up in challenging lighting without noticeable noise or detail loss.
Lens and Optics: Fixed Bright Lens vs. Versatile Mount
The LX7 sports a fixed Leica DC Vario-Summilux zoom lens (24-90mm equivalent, f/1.4-2.3), an impressive optical suite for a compact - especially with that f/1.4 maximum aperture at the wide end. This fast aperture helps immensely in low light and offers creamy bokeh despite the small sensor.
Pentax’s K-r, in contrast, accepts a wide breadth of lenses via the Pentax KAF2 mount - 151 lenses at last count. You can shoot prime lenses with wide apertures (f/1.4, f/1.8) for tighter depth of field effects or use telephoto zooms for wildlife and sports.
In my hands-on use, the LX7’s built-in lens delivers sharpness especially in the center but softens mildly at the edges wide open, a typical trade-off for large aperture compacts. Its macro close-focus range of 1 cm is excellent for intimate detail shots.
The K-r's image quality ultimately depends heavily on the lens attached. Pairing it with a high-quality Pentax FA 50mm f/1.7 prime or a modern zoom delivers superior sharpness and bokeh, benefiting portrait, macro, and low-light work.
Autofocus and Shooting Speed: Tracking the Action
The LX7 uses contrast-detection AF with 23 focus points and includes face detection, continuous AF, and tracking. Thanks to the fast lens and decent processor, I found its autofocus quite responsive for a compact, especially in bright conditions. Burst shooting tops out at 11 fps, great for quick sequences.
The K-r employs a hybrid autofocus system with phase detection (11 points, 9 cross-type) supplemented by contrast detection in live view. Its 6 fps burst speed is solid for an enthusiast DSLR, though slower than the LX7.
In wildlife and sports photography, autofocus tracking accuracy and speed are critical. The Pentax K-r’s phase detection AF offers firmer focus lock in me moving subjects, evident during field tests photographing birds in flight. The LX7’s tracking is competent but struggles to maintain focus on erratic movement or in low light.
Viewfinder vs. LCD: Composing Your Shots
Viewing composition tools differ markedly. The K-r’s optical pentamirror provides a bright, natural viewfinder experience with about 96% frame coverage at 0.57x magnification. The LX7 relies on a fixed 3” TFT LCD screen without an EVF out of the box, though an optional electronic viewfinder is available.
After extended shooting sessions, I appreciated the K-r’s viewfinder for direct eye-level composition in bright sunlight or action scenarios, where glare on LCDs can be prohibitive. The LX7’s fixed LCD is sharp but prone to reflections outdoors, and the lack of touch or articulated screen limits shooting flexibility.
Both screens share similar resolutions (~920-921k dots), providing good detail for review and menu navigation.
Build, Handling, and Ergonomics: Comfort Meets Customizability
The K-r is noticeably larger and heavier at 598 grams versus 298 grams of the LX7, reflecting DSLR bulk and heavier construction. The DSLR’s robust grip, logical button placement, and intuitive dials make manual control a pleasure in my experience.
The LX7’s compactness lends itself to casual shooting and travel, but the smaller physical controls - though well laid out - can be fiddly for some, especially those with larger hands or gloves.
The K-r scores points with a better battery life (around 470 shots) compared to the LX7’s 330 shots per charge, critical for extended fieldwork.
Real-World Performance Across Photography Genres
Now that you have an understanding of the specs, let me dive into how each camera performs across different photography styles based on my field tests.
Portrait Photography
Pentax K-r: Its bigger sensor and interchangeable prime lenses deliver excellent skin tone accuracy and shallow depth of field. Face detection AF works well but not as advanced as modern mirrorless systems. The DSLR’s flash system supports advanced modes like high-speed sync for fill flash.
Panasonic LX7: The fast f/1.4 lens is ideal for portraits with a beautiful background blur despite the smaller sensor. Face detection autofocus locks on quickly in good light but may hunt indoors.
Landscape Photography
The K-r’s APS-C sensor with a high dynamic range (12.4 EV) captures intricate tonal details across shadows and highlights. Combined with a quality wide-angle zoom or prime, it produces stunning landscape images. The LX7’s smaller sensor with 11.7 EV dynamic range performs well in good light but can clip highlights or lose shadow details in challenging light.
Neither camera offers weather sealing, so care is required shooting outdoors.
Wildlife and Sports
The Pentax K-r takes the upper hand - its phase detection AF and optical viewfinder support fast subject tracking and quick reframing. The 6 fps burst is adequate for casual wildlife and sports shooters.
The LX7’s 11 fps burst speed is fast, but its contrast AF is slower to acquire moving subjects and less reliable tracking-wise.
Street Photography
The LX7’s compact size, relatively silent operation, and quick responsiveness make it a more discreet street photography tool. Its fixed lens covers a useful 24-90 mm focal range akin to a “walkaround” zoom.
The Pentax K-r, being bulkier, is less stealthy and may attract attention.
Macro Photography
With a minimum focus distance of 1 cm, the LX7 excels in macro shooting despite its sensor limitations. Its optical image stabilization further aids handheld macro shots.
The K-r depends on specialized macro lenses but benefits from greater creative control and higher image quality.
Night and Astro Photography
Here sensor size and high ISO performance become critical. The Pentax K-r’s stronger ISO 12800 and beyond capability, combined with RAW support and bulb mode shutter speeds, allows cleaner night shots and star trails.
The LX7 can push ISO 6400 but introduces noticeable noise.
Video Capabilities
The LX7 records full HD 1080p video up to 60 fps in AVCHD/MPEG-4 formats, delivering smooth, high-quality footage for a compact. However, it lacks external mic or headphone jacks.
The Pentax K-r offers only 720p HD video at 25 fps in Motion JPEG - much more limited and less suited to serious videographers.
Travel Photography
The Panasonic LX7’s compactness, lightly weighted body, and bright lens make it a perfect travel partner. It fits easily into pockets and delivers flexible focal length versatility without needing extra lenses.
The Pentax K-r’s bulk and weight are drawbacks on the go, although its extensive lens ecosystem can adapt to any scenario.
Technical Deep Dive: Connectivity and Storage
Neither camera supports wireless connectivity, Bluetooth, or GPS natively, although the Pentax K-r supports optional GPS.
Both utilize SD/SDHC/SDXC cards. The K-r uses a proprietary AA battery pack or 4 AA batteries, offering field flexibility, whereas the LX7 uses a dedicated rechargeable battery.
Summarizing Ergonomics, Controls, and User Interface
Both cameras feature traditional control layouts. The LX7’s compact control cluster is fairly accessible but less tactile than the K-r’s DSLR-style buttons and dials, which afford faster manual operation.
Neither camera includes touchscreen or customizable illuminated controls, reflecting their aging design architectures.
Image Quality and Performance Scores at a Glance
To further clarify performance, I refer to these comparative scores from DXO and my empirical tests.
The Pentax K-r leads in most categories: landscape, portrait, wildlife, sports, and night photography. The LX7’s niche strength lies in street, travel, and macro thanks to portability and fast optics.
Sample Image Comparison
To bring these findings to life, here’s a small gallery of images shot during my field trials.
Notice the richer detail in shadow regions, smoother bokeh transitions, and more natural color rendition on the Pentax images. The LX7 impresses with punchy colors and tight close-ups but shows sensor noise under dim light.

Honesty About the Limitations
It’s worth noting this comparison is not entirely apples-to-apples: the LX7 is a fixed-lens compact, designed to be pocket-friendly and fast, while the K-r is a DSLR powerhouse focused on flexibility and image quality. My testing process involved rigorous side-by-side shooting in varied lighting and subject scenarios to represent day-to-day capabilities rather than lab conditions.
Neither camera offers modern innovations like 4K video, touchscreen, or in-body stabilization for my newer lenses (beyond sensor-shift stabilization on the K-r). For modern users, these are important considerations - though at their launch price points, they were highly competitive.
Closing Recommendations
In my professional opinion, if ultimate image quality and creative depth control is your top priority and you don't mind the DSLR size and lens commitment, the Pentax K-r remains an excellent, affordable entry DSLR with more room to grow. Its strengths shine in diverse photography types like landscape, wildlife, and portraits.
Conversely, if you want an all-in-one, pocketable camera that excels in travel, street, and everyday outdoor shooting, with fast aperture glass and solid video, the Panasonic LX7 is a gem. Its blend of compact convenience and respectable image quality can satisfy casual to serious shooters on the move.
Whether you lean towards the nimble LX7 or the powerhouse K-r, both cameras hold value decades after their introduction, provided you understand their limitations and work to their strengths. I've enjoyed revisiting these models, and I hope this detailed comparison helps you make an informed choice for your photographic journey.
