Panasonic Lumix DMC-SZ1 vs Pentax Optio E90: A Detailed Comparison for Compact Camera Buyers in 2024

When it comes to small sensor compact cameras, the market often offers a confusing array of options. Today, I’m putting two budget-oriented compacts head-to-head: the Panasonic Lumix DMC-SZ1 (2012) and the Pentax Optio E90 (2010). Both cameras fall into the entry-level compact category, aimed primarily at casual shooters, travel enthusiasts, and those seeking ultra-portable “grab and go” options without sacrificing versatility.

I’ve personally tested hundreds of cameras in this niche, using controlled lab setups and real-world shooting to evaluate image quality, autofocus responsiveness, ergonomics, and usability. Here, I’ll share a comprehensive breakdown covering portraiture, landscapes, wildlife, and more - with a particular emphasis on practical use cases and value.

Let’s begin with a side-by-side look at their physicality and controls.

Compact Convenience: Physical Size and Handling Differences

Both cameras are designed for portability, but their build and ergonomic approach differ slightly.

• Panasonic SZ1 dimensions: 99x59x21mm, weight 131g
• Pentax E90 dimensions: 102x59x25mm, weight 145g

The Panasonic SZ1 feels marginally slimmer and lighter, which lends it an edge in pocketability. It also features an optical zoom range equivalent to 25-250mm, providing 10x zoom. The Pentax E90 covers a shorter zoom range - 32-95mm equivalent (3x zoom) - but offers a slightly faster maximum shutter speed (up to 1/2000s vs 1/1600s on the SZ1).

Handling-wise, both cameras rely on menus and minimal physical buttons - common at this level - which can slow down access to settings like exposure compensation or white balance changes.

The SZ1 has a slight ergonomic advantage in shape, tapering edges that fit more comfortably in the hand, while the E90 feels somewhat boxier. Neither offers a dedicated manual focus ring or advanced grip features, limiting their appeal to casual shooters over enthusiast use.

Top-Down Look: Control Layout and User Interface

Looking at the layout from above, you’ll notice the Panasonic SZ1 sports slightly larger zoom and shutter buttons. This helps when shooting on the move, as the buttons are easier to find and operate blind. The sensor-close placement of the mode dial is also typical of the time.

The Pentax E90 offers a similar control scheme but relies heavily on menu navigation due to fewer physical buttons. The lack of a touchscreen in both cameras means that navigating settings is less intuitive compared to newer models.

From a user experience standpoint, the Panasonic’s slightly more responsive buttons earned it better marks during my field testing, especially when shooting moving subjects or trying to adjust settings quickly during travel or street photography.

Sensor Technology and Image Quality: What’s Under the Hood?

Both cameras employ a 1/2.3-inch CCD sensor with an effective resolution of:

• Panasonic SZ1 – 16MP
• Pentax E90 – 10MP

While a higher resolution can enable larger prints and cropping flexibility, the benefits are constrained by sensor size and noise handling capabilities. In my lab tests, the Panasonic’s 16MP sensor produced slightly sharper images due to greater pixel density. However, this also increased noise levels at higher ISO settings.

The Pentax’s 10MP sensor was a bit more forgiving with noise thanks to larger individual pixels. Both cameras include an anti-aliasing filter, which slightly softens ultra-fine detail to prevent moiré patterns but impacts ultimate sharpness.

In practice, you can expect similar image quality from both cameras in good lighting, but the Panasonic’s extra resolution benefits landscape and travel photographers who may want to crop or print larger. The Pentax is arguably a better option if you prioritize cleaner images at base and mid-ISO settings (up to ISO 400–800 range).

Neither camera supports RAW image capture, limiting your ability to fine-tune images in post-processing. This omission is expected in models of these vintage and price point but restricts versatility for serious enthusiasts.

LCD Screens and User Interface: How You Frame and Review Images

The SZ1 boasts a 3-inch fixed TFT LCD with 230k-dot resolution, while the E90 uses a slightly smaller 2.7-inch screen at the same resolution.

Although the difference in screen size seems minor, the larger screen on the Panasonic offers a more comfortable framing and image review experience - a positive for travel and street photographers needing quick composition checks. Neither screen supports touch input or articulates, which can reduce flexibility when shooting at odd angles.

During my hands-on testing, I also noticed the Panasonic’s screen provides slightly better color reproduction and brightness outdoors, making it marginally easier to review shots in sunlight.

Zoom and Lens Comparison: Versatility in Framing

The Panasonic SZ1’s lens provides an impressive 10x optical zoom range (25-250mm equivalent), while the Pentax E90 caps out at a 3x zoom (32-95mm equivalent). Both have a maximum aperture range of f/3.1 to f/5.9.

Having tested both extensively:

• Panasonic’s longer zoom makes it far more capable for wildlife and sports snapshots, where getting closer to distant subjects matters.
• The Pentax’s shorter zoom performs well for casual landscapes and portraiture but falters in telephoto reach.

Macro capabilities are close, with the Panasonic focusing down to about 4cm, and the Pentax from 6cm. Optical image stabilization is present on the Panasonic but absent in the Pentax, giving the SZ1 an edge in handheld shooting situations, especially in low light or at longer focal lengths.

Autofocus Performance: Speed and Accuracy in Real Life

The SZ1 uses a contrast-detection autofocus system with 23 focus points including face detection, whereas the Pentax relies on a simpler 3-point contrast AF system with no face detection.

In field conditions:

• I found the Panasonic’s autofocus to be markedly faster and more reliable, especially with moving subjects, thanks to more AF points and face detection.
• The Pentax autofocus was adequate in static scenes but struggled with tracking action or low-contrast situations.

This difference affects wildlife, sports, and street photography where autofocus responsiveness is critical.

Burst Shooting and Shutter Speeds: Capturing the Action

The Panasonic maxes out at 1 fps continuous shooting, limited by processor and buffer constraints, while Pentax E90 did not specify burst capabilities, suggesting it’s not a priority feature.

Neither camera is suited for serious sports photography, but the Panasonic offers slightly better shutter speed flexibility (up to 1/1600s vs 1/2000s on the Pentax). However, this difference is marginal in real-world use.

Flash Systems and Low Light Performance

Built-in flash coverage:

• Panasonic SZ1: up to 5.6m
• Pentax E90: up to 3.5m

The Panasonic’s flash provides better illumination range and modes (Auto, On, Off, Red-eye reduction), whereas the Pentax offers fewer flash options.

In low light, Panasonic’s optical image stabilization and higher ISO ceiling (6400 vs 3200 ISO max) offer improved handheld shooting performance. I tested shooting indoor and evening scenes and consistently found the SZ1’s images exhibited less blur and more usable detail.

Video Capabilities: What to Expect

Both cameras offer HD video capture at 1280x720 resolution, but with notable differences:

• Panasonic SZ1: 30fps video in MPEG-4 format
• Pentax E90: 15fps at 1280x720, with additional lower resolution frame rates, recording in Motion JPEG format

The SZ1’s smoother frame rate and more efficient codec render it more practical for casual video capture, although professional video work is beyond these cameras’ scope. Neither model includes microphone or headphone jacks for audio input/output.

Battery Life and Storage

• Panasonic SZ1 uses a proprietary battery pack, rated for around 250 shots per charge.
• Pentax E90 uses two AA batteries, a convenient solution if you’re traveling and can’t charge but limiting in capacity and causes bulkier design.

Both cameras store images on SD or SDHC cards, shared single slots with no dual card options - typical given their compact class.

Connectivity and Additional Features

Neither Panasonic SZ1 nor Pentax E90 offers wireless connectivity, Bluetooth, NFC, GPS, or HDMI output. USB 2.0 ports exist on both for file transfer, but neither support live tethering or fast transfer speeds by modern standards.

Durability and Weather Sealing

Both cameras lack environmental sealing, dustproofing, waterproofing, or shockproofing. Their lightweight builds correspond strictly to casual, protected usage rather than professional or adventure photography contexts.
