Comparing the Panasonic Lumix DMC-LZ40 and Pentax MX-1: Small-Sensor Cameras Put to the Test

Choosing a compact camera that delivers on both performance and value can be a subtle balancing act. Today, I’m diving deep into the comparative strengths and weaknesses of two popular models from the mid-2010s small sensor category: the Panasonic Lumix DMC-LZ40 - a superzoom bridge camera designed for maximum reach - and the Pentax MX-1, a stylish compact with a fast lens and solid image controls. Though these cameras occupy the same general market, their designs and target users differ markedly, so understanding their nuances will help you pick the right tool for your shooting style and photographic ambitions.

Over many hours of side-by-side field and lab testing, I examined everything from image quality and ergonomics to autofocus performance and video capabilities. I’ve integrated technical benchmarks with practical shooting experience across multiple genres: portrait, landscape, wildlife, and more. Let’s break down their performance and ultimately help you decide which camera earns a spot in your gear bag.

First Impressions and Handling: Size, Controls, and Feel

When you pick up a camera, the physical interface and ergonomics can make or break your experience. The Panasonic LZ40 is a classic “bridge” style camera - it looks somewhat DSLR-ish with a pronounced grip and a long zoom barrel. Meanwhile, the Pentax MX-1 sports a compact, retro-inspired design with a more subdued form factor.

Physically, the Panasonic LZ40 is chunkier and heavier at 524g compared to the MX-1’s 391g. Its larger dimensions (126 x 87 x 94 mm) give it a more solid feel in hand and help steady the long zoom lens, but it also means less pocketability. The MX-1 is quite slim at 122 x 61 x 51 mm, making it ideal for discreet shooting or travel when minimalism is key.

Both cameras feature fixed lenses - the LZ40 with an enormous 42x zoom lens (22-924mm equivalent) and the MX-1 a more moderate 4x zoom (28-112mm equivalent). This difference is immediately palpable when you hold and shoot: the LZ40 feels like a superzoom bridge meant to reach far, the MX-1 more like a premium compact emphasizing lens speed and build quality over reach.

Let’s look at controls next:

Here the MX-1 clearly shines, with dedicated dials for shutter speed and exposure compensation, plus a classic aperture ring on the lens. This affords manual exposure control that feels intuitive and tactile - a real plus for enthusiasts wanting creative control on the fly. The Panasonic LZ40 offers manual exposure modes, but lacks dedicated dials, relying more on menu navigation and button combos, which can interrupt your workflow in dynamic shooting situations.

Our handheld experience: If you prefer an analogue-influenced interface for real-time adjustments, the MX-1 feels authentic and engaging. The LZ40’s control scheme is more entry-level friendly but can get cumbersome with quick scene changes.

Sensor Technology and Image Quality: Bridging Resolution and Dynamic Range

Both cameras utilize small sensors, but the differences here are instructive. The Panasonic LZ40 has a 1/2.3” CCD sensor with a whopping 20MP resolution, while the Pentax MX-1 packs a larger 1/1.7” CMOS sensor at 12MP. Let’s unpack what these specs mean practically.

While a higher megapixel count in the LZ40 might seem advantageous, sensor size and technology often matter more for image quality - especially low light and dynamic range. The MX-1’s 1/1.7” CMOS sensor covers approximately 41.5 mm² versus the LZ40’s smaller 28 mm² CCD area. This enables larger photodiodes and better noise control.

In our laboratory testing and field conditions:

• The Panasonic LZ40 delivers sharp images in bright daylight with decent color reproduction. However, its small sensor and CCD technology limit dynamic range - shadows clip easily and highlights can blow out under harsh lighting. The maximum ISO tops out at 1600 (native) and 6400 boosted, but noise rises sharply beyond ISO 400.
• The Pentax MX-1, in contrast, shows better tonal gradation and expanded dynamic range, scoring 11.3 EV per DXOmark tests (unofficial, but my practical experience confirms this). It handles shadows and highlights concurrently with less clipping, and the sensor’s CMOS design allows ISO sensitivity up to 12800 with usable noise levels up to ISO 800–1600, a substantial improvement for low-light shooters.

Regarding megapixels: The MX-1’s 12MP resolution is sufficient for most uses, including 8x10 inch prints, while the 20MP LZ40 might appeal if you want larger prints or extensive cropping. But bear in mind the practical limits with noise and dynamic range.

Focusing Systems and Speed: Who Nabs the Shot Faster?

Autofocus (AF) systems in compact cameras often reflect their market positioning. Testing the Panasonic LZ40 and Pentax MX-1 under various focus conditions reveals significant differences.

The LZ40 has a 9-point contrast-detection AF system, including face detection, but no phase-detection. It offers continuous AF and single AF with tracking, but its slow processor and limited AF points struggle in fast-paced environments.

The MX-1 uses a 25-point contrast-detection system, still no phase-detection, but with superior algorithms offering faster lock times and better face detection accuracy. In practical terms:

• Panasonic LZ40 autofocus feels sluggish - locking can take over a second in low contrast or low light. Tracking moving subjects, especially wildlife or sports, is a race the LZ40 mostly loses due to lag.
• Pentax MX-1 autofocus feels snappier and more precise on still subjects and moderate movement. However, it’s still not up to modern mirrorless or DSLR AF speeds - consider it adequate but not stellar for wildlife or fast sports action.

Both cameras allow manual focus, but the MX-1’s dedicated focus ring and manual controls make it much easier and more satisfying to use for deliberate focus adjustments. The Panasonic’s lack of a manual focus ring hampers control, especially in macro or creative focus work.

Variety of Photography Genres: Strengths and Weaknesses in Action

Every camera shines differently depending on your shooting goals. Let’s walk through how these two contenders measure up across major photography disciplines:

Portrait Photography

Portraiture requires accurate skin tones, shallow depth of field, and reliable eye detection AF.

• Pentax MX-1’s faster lens (F1.8-2.5) enables creamy bokeh and effective subject separation even at moderate zooms (28-112 mm range), rendering skin tones nicely with balanced color reproduction thanks to the CMOS sensor. Its face detection works well for headshots.
• The Panasonic LZ40 struggles here because of its slower lens (F3.0-6.5) - achieving background blur at longer focal lengths is challenging due to small sensor and narrower aperture. Skin tones are decent but less nuanced, shadow detail suffers, and eye-focused AF functionality is absent.

Landscape Photography

Landscape shooters prize resolution, dynamic range, and weather resistance.

• Pentax MX-1 edges ahead due to better dynamic range and a sensor that delivers sharper corners and better color fidelity in daylight. The lens is sharp wide open and tilting rear screen aids composing tricky shots.
• The LZ40 offers an extraordinary zoom for framing distant mountains or cityscapes but falls short on overall image quality and lacks any weather resistance or ruggedness, which may be a deal-breaker outdoors.

Wildlife and Sports Photography

Fast autofocus, high burst frame rate, and telephoto reach are essential.

• Panasonic LZ40’s superzoom lens certainly wins in reach (up to 924 mm equivalent), but this advantage is tempered by sluggish AF, single fps continuous shooting, and limited buffer capacity. It’s more for casual documentarians than action pros.
• Pentax MX-1 autofocus speed and burst rate (1 fps) are also modest; sports and wildlife photography will be challenging regardless, but MX-1’s superior image noise control in low light can help capture better results during golden hour.

Street Photography

Here, discretion, portability, and responsiveness dominate.

• Pentax MX-1 is more street-friendly due to its compact size, discreet design, and fast aperture lens enabling excellent low-light street scenes.

Macro Photography

Close focusing distance and precision focus are everything here.

Both cameras offer a 1 cm macro focus range:

• MX-1’s manual focus ring and sensor-shift stabilization give it a definite edge for precision macro work.
• Panasonic’s optical stabilization is decent but coarse AF and slower controls limit its macro appeal.

Night and Astro Photography

High ISO performance and long exposure capability are critical.

• While both cameras lack specialized astro modes, MX-1’s better high ISO noise control and longer shutter speed range (up to 30 seconds) give it the benefit.
• The LZ40 caps at 15 seconds shutter and has noisier high ISO images, hindering night sky detail capture.

Video Capabilities

The Panasonic shoots 720p at 30 fps in Motion JPEG format, while the Pentax MX-1 punches above with 1080p at 30 fps and additional 720p at 60 fps, using more efficient MPEG-4/H.264 encoding.

• The MX-1’s sensor-shift stabilization also helps video steadiness, though no microphone or headphone ports exist on either.
• The LZ40 supports an external microphone via a 3.5mm mic port - rare at its price but video quality remains dated.

Travel Photography

For travel, small size, battery life, and versatile zoom range matter.

• The Panasonic LZ40 wins with a huge zoom range, excellent battery life (320 shots), and better zoom versatility overall - great for travelers wanting one-lens-all convenience.
• However, its bulk and image quality trade-offs are a consideration.
• The Pentax MX-1 is lighter, more compact, and produces higher quality images - suitable when image fidelity and portability balance matters more than superzoom reach.

Professional Work

In professional contexts, RAW format support and file quality are defining.

• Notably, the Panasonic LZ40 offers no RAW support, pinning users to JPEG only, limiting post-processing flexibility.
• The Pentax MX-1 supports RAW, a boon for pros and enthusiasts who want post-capture latitude.
• Neither camera offers weather sealing or rugged construction, limiting professional use in harsh environments.

LCD Screens and User Interface: Composing and Reviewing Your Shots

The rear screen is your constant companion, so let’s see whose screen delights more.

The Pentax MX-1’s 3-inch tilting TFT LCD with 920k dots and anti-reflective coating blows the LZ40’s fixed 3-inch 460k dot screen out of the water in both brightness and flexibility. Tilting aids shooting from awkward angles, crucial for macro, street, and landscape work.

The Panasonic’s screen feels dated: dull with limited resolution, frustrating when reviewing focus or details under bright sunlight. Both lack touchscreen support, a disadvantage compared to current standards, but the MX-1’s superior screen maintains a clear user experience edge here.
