Panasonic strikes a balance between retro charm and modern efficiency. The LX100’s top-plate dials - including aperture ring, shutter speed dial, and exposure compensation - give direct manual control, a joy for enthusiasts who like tactile feedback. The control layout is intuitive, and all buttons are well placed for quick access.

The K110D employs a more traditional DSLR control scheme, including a mode dial with common PASM options and a dedicated shutter speed dial - a uniquely Pentax touch in entry-level DSLRs. Buttons are fewer and more spaced out, reflecting its beginner-friendly philosophy. Its grip is slightly large but comfortable, suitable for extended shoots.

Summary of handling:

• LX100 - compact, well-built, dials for manual controls, lightweight, ideal for on-the-go use
• K110D - sturdy DSLR feel, straightforward controls, less portable, better for users who prefer optical viewfinder and lens versatility

Sensor and Image Quality: Four Thirds Compact vs APS-C DSLR

Sensor size and technology are the heart of image quality. Here the comparison becomes very interesting.

Sensor size and specs: Panasonic LX100 features a Four Thirds sensor; Pentax K110D sports an APS-C CCD sensor

Panasonic LX100:

• Four Thirds CMOS sensor, 13 MP resolution (4112x3088)
• Sensor size: 17.3 x 13 mm (224.9 mm²)
• No optical low-pass filter (mild anti-aliasing filter present)
• Native ISO 200-25600 range, optical image stabilization
• Venus Engine processor, RAW support with 12.5 EV dynamic range per DxOMark

Pentax K110D:

• APS-C CCD sensor, 6 MP resolution (3008x2008)
• Sensor size: 23.5 x 15.7 mm (368.95 mm²)
• Optical low-pass filter enabled
• ISO 200-3200 native sensitivity
• No image stabilization in body, RAW support

While the K110D’s larger APS-C sensor theoretically promises superior light gathering and better high ISO performance, the LX100’s modern Four Thirds sensor and powerful Venus Engine bring it surprisingly close. In fact, Panasonic’s newer sensor tech plus stabilized optics help reduce noise and preserve detail better than you might expect from a smaller sensor.

In practice, I found the LX100 delivered punchier, cleaner images with smoother gradations and richer colors at base and moderate ISOs (200-1600). The K110D’s CCD sensor renders pleasing tones, particularly in daylight, but shows more noise and falls short in dynamic range beyond ISO 400.

Here’s a key point: the LX100’s sensor resolution nearly doubles that of K110D, translating into sharper images and more cropping flexibility. Its effective ISO ceiling of 25600, while not always usable, outpaces the K110D’s ISO 3200 max.

You also benefit from the LX100’s greater dynamic range, delivering better retention in shadows and highlights, which is vital for landscape and high-contrast conditions.

Summary comparison:

• LX100 wins in sensor tech, resolution, and noise handling
• K110D offers a larger physical sensor but lags in resolution and dynamic range due to CCD aging tech

Autofocus and Shooting Performance: Precision vs Tradition

Autofocus speed and accuracy are crucial for capturing fleeting moments, action, or wildlife.

Panasonic LX100:

• Contrast-detection AF with 49 focus points
• Face detection autofocus
• AF single, continuous, tracking modes
• Max shutter speed 1/4000s, electronic shutter up to 1/16000s
• Burst shooting at 11 fps

Pentax K110D:

• Phase-detection AF with 11 focus points (no face detection)
• AF modes: single, continuous, selective
• Max shutter speed 1/4000s
• Burst shooting at 3 fps

I tested autofocus on both in low light, wildlife, and sports scenarios. The Pentax K110D’s phase-detection system was reliable but noticeably slower to lock on, especially in dim conditions, and lacked sophisticated tracking features. Its lower burst rate limits action shooting potential.

Conversely, the LX100’s contrast-based AF is surprisingly snappy, with the bonus of face detection providing quick focus in portrait or candid contexts. Its faster burst speed and silent electronic shutter offered flexibility in versatile shooting environments.

Ergonomics in shooting:
The LX100’s EVF gives real-time exposure previews, assisting manual tweaks, while the K110D relies on its optical viewfinder, prized for no lag but lacking exposure simulation.

Summary:

• LX100 offers faster, smarter AF suited better for street, wildlife, and sports
• K110D suits slower-paced shooting, studio, or controlled settings

Lens and System Flexibility

One of DSLR’s main pulls is its interchangeable lens ecosystem, an area where these two cameras sharply diverge.

Panasonic LX100:

• Fixed Leica 24-75mm equiv. lens, 3.1x zoom, fast aperture f/1.7-2.8
• Optical stabilization
• Compact, no lens swaps possible

Pentax K110D:

• Pentax KAF mount, compatibility with 151 lenses (including many budget primes, zooms, and legacy glass)
• No in-body stabilization, relies on lens IS if available
• Macro and telephoto options at varying price points

Here, the choice depends on your shooting style. The LX100’s lens is impressively versatile and sharp, especially wide open. Its bright aperture aids low-light and shallow depth-of-field work. But its zoom range maxes out modestly; telephoto reach is limited for serious wildlife or sports.

The K110D offers complete freedom to adapt lenses tailored to genre - macro, ultrawide, long telephoto - and hence can evolve with you. For enthusiasts wanting system growth, this is a compelling factor.

LCD and Viewfinder Experience: Digital Convenience vs Optical Tradition
