๐จ Design and Build Quality
The Panasonic Lumix S 18mm f/1.8 lens is part of Panasonic’s f/1.8 series, sharing the same physical dimensions and design as its siblings. This provides consistent handling when using multiple lenses in the series.
Size and Weight
- Lens dimensions: 73.6mm x 82mm (diameter x length)
- Weight: 340g
Despite being an ultra-wide lens, it maintains a remarkably compact and lightweight design, offering excellent portability. It balances perfectly with mid-sized mirrorless cameras like the Panasonic S5.
Build Quality
While constructed primarily from plastic, the lens maintains a premium feel. It features a metal mount for increased durability and weather sealing for use in various environments.
Design Features
- 67mm filter thread: Compatible with filters used across Panasonic’s f/1.8 series
- Focus ring: Wide and smooth-operating focus ring
- AF/MF switch: Conveniently located on the lens barrel for easy focus mode switching
๐ธ Optical Performance
The Panasonic Lumix S 18mm f/1.8 lens demonstrates excellent optical performance despite its ultra-wide nature.
Sharpness
- Center: Excellent sharpness even at f/1.8. Slight improvement when stopped down to f/2.8, though f/1.8 performance is satisfactory for most situations.
- Corners: Usable at f/1.8, with significant improvement at f/2.8-f/4. Peak corner sharpness is achieved between f/4 and f/8.
Chromatic Aberration
Chromatic aberration is minimal in most real-world shooting situations. Some lateral chromatic aberration may appear in high-contrast scenarios but is easily correctable in post-processing.
Distortion
With lens profile corrections applied, distortion is minimal. Without correction, some barrel distortion is present, though typical for an ultra-wide lens.
Vignetting
- f/1.8: Noticeable vignetting
- f/2.8: Significantly improved
- f/4 and beyond: Minimal vignetting
Flare and Ghosting Control
Excellent flare and ghosting control. Even when shooting directly at the sun at f/1.8, minimal flare occurs with negligible impact on contrast.
Bokeh
Despite being an ultra-wide lens, the bright f/1.8 aperture and close minimum focus distance (18cm) allow for depth of field control. Bokeh quality is generally smooth and circular, though some situations may show slight haloing around bokeh edges.
๐ฅ Video Performance
The Panasonic Lumix S 18mm f/1.8 lens includes several features optimized for video shooting, making it an attractive option for videographers.
Focus Breathing
Focus breathing is extremely well-controlled. When focusing from 1m to infinity, focus breathing is barely noticeable.
Focus Control
- Supports both linear and non-linear focus control
- Linear focus control allows selection of rotation angle from 90 to 360 degrees
AF Performance
- Fast and accurate focusing using linear AF motor
- Extremely quiet AF operation minimizing noise during video recording
Aperture Transitions
Aperture changes during video recording are exceptionally smooth, with minimal stepping compared to other lenses, allowing for natural exposure transitions.
Wide-Angle Effects
The 18mm ultra-wide angle of view is particularly useful for:
- Landscape videography
- Architectural footage
- Shooting in tight spaces
- Vlog-style self-recording
Stability
The light weight enables stable shooting when using gimbals or steadicams.
๐ Real-World Experience
Landscape Photography
The 18mm ultra-wide angle is perfect for capturing expansive landscapes. The bright f/1.8 aperture is advantageous for night landscapes and astrophotography.
Architectural Photography
Effectively captures entire buildings while maintaining good distortion control, preserving architectural lines naturally.
Street Photography
The compact size and light weight make it comfortable for extended shooting sessions. The wide angle allows for dynamic street shots including environmental context.
Vlogging and Self-Recording
The wide angle is ideal for self-recording, capturing both the subject and background effectively for vlogging and YouTube content creation.
Close-up Photography
The 18cm minimum focus distance enables close-up shooting. The 0.2x maximum magnification allows for capturing small objects with good detail.
