Choosing the right compact camera can be daunting given the sheer range of choices on the market. Among small sensor compacts, the Olympus Stylus 7040 (also known as the mju 7040) and the Panasonic Lumix DMC-ZS40 (Lumix TZ60 in some regions) stand out as affordable options that cater to everyday photographers seeking portability without sacrificing zoom reach or basic image quality.

I’ve put both models through real-world tests, examining their technical specs, handling, image quality, autofocus, video capabilities, and more - all with the goal of helping you find the best fit depending on your style of photography and budget. Having hands-on experience with thousands of cameras over 15 years, I approach this comparison first and foremost from your perspective, balancing specs with practical performance insights.

Let’s dive in.

Hold Them in Your Hands: Size, Design, and Ergonomics

Both Olympus 7040 and Panasonic ZS40 slot firmly in the compact category, but there are notable distinctions in their ergonomics and physical presence.

• Olympus 7040: It is more pocketable at 95 x 56 x 26 mm with a feather-light 144g body weight. Its simple, curvy design makes it very travel-friendly.
• Panasonic ZS40: Larger and heavier at 111 x 64 x 34 mm and 240g, the ZS40 sacrifices some ultra-portability for extra features and handling comfort.

On testing, the Panasonic felt more comfortable for extended shoots thanks to its slightly larger grip and better button placement but the Olympus scores for discreteness in street and travel photography owing to its smaller footprint.

Moving to control layout:

The Olympus has a pared-down interface with minimal buttons and no manual controls - aimed at point-and-shoot simplicity. The Panasonic, however, offers more physical controls including dedicated dials for aperture, shutter speed, and exposure compensation, making it a better choice if you like to actively engage with settings beyond Auto mode.

Quick takeaway:
If you want something ultra-portable for casual everyday shooting, the Olympus 7040 handles well. For more hands-on control during longer sessions, the Panasonic ZS40’s ergonomics and button layout will suit you better.

Sensor Technology & Image Quality - The Heart of the Matter

A camera’s sensor greatly influences image quality, and here the two diverge in key respects.

What I found in testing:

The CMOS sensor and Venus Engine processor in the Panasonic enable greater dynamic range, improved low-light capability, and support for RAW files - a significant advantage for enthusiasts seeking post-processing flexibility. The Olympus's CCD sensor, while decent for daylight shooting, shows more noise at higher ISOs and lacks RAW output, limiting creative control.

In side-by-side landscape shots, the Panasonic delivered crisper detail with less noise in shadow areas and retained color saturation more faithfully. The Olympus images sometimes felt softer with less tonal gradation.

On resolution, the Panasonic's higher 18MP count translates to more cropping freedom, especially valuable in wildlife or sports where detail retention is crucial.

Image sharpness and detail tests:
The Panasonic’s sensor paired with its quality lens produced noticeably sharper results in center and corner detail charts. Olympus’s images, while good for web sharing and snapshots, don’t have the same level of detail or tonality subtlety.

Summary on sensor and image quality:
The Panasonic ZS40 has a definite edge in sensor technology and image quality, making it the better choice if image fidelity and post-production are priorities.

Autofocus & Shooting Performance: Speed and Accuracy

Focusing and shooting speeds can make or break candid, sports, wildlife, and street photography, so I spent significant time testing AF systems, burst rates, and shutter lag.

The Panasonic’s 23-point AF with face detection and tracking delivers noticeably quicker, more reliable focus acquisition, particularly in more challenging light (shade, indoor) or when subjects are moving. Continuous autofocus and a ten-frame per second burst rate mean the Panasonic is well suited for action and wildlife photography.

The Olympus 7040's AF is slower and limited to single autofocus with tracking that’s not highly reliable. In practice, this means you’ll miss a lot of fast action or fleeting moments.

Practical impact:
I found the Olympus struggles locking focus on moving subjects, making it less ideal for sports or wildlife shooters. Conversely, the Panasonic handled quickly shifting compositions with ease, even in dim conditions.

Build Quality and Weather Resistance

Neither camera offers professional-level weather sealing or rugged build. Both are plastic-bodied compacts intended for casual daily use.

• Olympus 7040: No weather or dust sealing. Lightweight plastic makes it less robust under rough handling.
• Panasonic ZS40: Also lacks weather sealing but feels sturdier due to its larger size; slightly more durable buttons.

This means neither is suitable for extreme environments or heavy outdoor use without protective cases.

Display and Viewfinder: Composing Your Shots

Both cameras have 3-inch fixed LCDs, but the Panasonic’s screen boasts higher resolution and is easier to use in bright sunlight.

I found the Panasonic’s screen much clearer for manual focusing and reviewing images. The Olympus’s dim lower-res LCD can frustrate in daylight.

The Panasonic’s built-in EVF is a strong plus for shooting in bright light or composing with stability. Olympus’s lack of viewfinder limits composing options in sunshine or fast-paced situations.

Lens and Zoom Capabilities: How Far Can You Reach?

The Panasonic's powerful 30x zoom (24–720mm equiv.) offers phenomenal reach for wildlife and travel, letting you capture distant details without lenses to carry. In contrast, the Olympus’s 7x zoom is more limited, tailored to everyday snapshots.

Wide-angle coverage on the Panasonic also provides greater landscape framing flexibility.

While the Panasonic’s max aperture narrows at longer focal lengths (typical in compacts), I found its lens reasonably sharp across the range, though edge softness creeps in at extremes.

The Olympus lens is reasonably sharp in the center but shows more softening in the corners, limiting cropping flexibility.

Summarized view:
For photographers needing extended zoom, the ZS40 is outstanding. For simple casual shooting, the Olympus lens suffices.

Image Stabilization: Keeping Shots Sharp

• Olympus 7040: Sensor-shift image stabilization helps compensate for camera shake.
• Panasonic ZS40: Optical image stabilization (OIS) integrated into the lens.

In my tests, both effectively minimized blur at moderate zoom levels. However, with the Panasonic’s longer zoom, OIS proved essential to handhold without motion blur.

Video Capabilities: Moving Images

Panasonic clearly leads with Full HD 1080p video at up to 60 fps, letting you capture smooth motion. It also records in advanced AVCHD format, suited for quality preservation.

Olympus is limited to 720p HD recording at 30 fps, which may be insufficient for serious videography.

Neither has external mic inputs; thus audio quality is basic on both.

Bottom line:
For casual videos, Olympus’s basic HD may be enough, but Panasonic gives you more versatility and quality.

Connectivity, Storage, and Battery Life

Connectivity is essential for modern workflows.

The Panasonic’s built-in Wi-Fi and NFC make image sharing convenient while on the move. Its GPS tagging is valuable for travel photographers who want geotagged images.

The Olympus lacks wireless or GPS features, limiting connectivity to manual USB transfers.

Battery life on the Panasonic is better documented and more reliable for a full day of shooting.
