  • Compact and portable.
  • Extremely sharp across the frame.

Cons:

  • The 15mm focal length may not be wide enough for some.
  • Slightly less shift range than the 20mm lens.
Comparing the Focal Lengths: 20mm vs 15mm
Field of View

The Laowa 20mm offers a slightly wider field of view compared to the 15mm. This gives you more room to capture expansive scenes, making it ideal for architectural shots and interior photography.

Ideal Applications for Both Lenses
  • 20mm F/4 Zero-D Shift: Best for architecture, urban environments, and interiors where wide scenes are essential.
  • 15mm F/4.5 Zero-D Shift: Great for landscape photography and outdoor shooting, offering a compact solution for photographers on the go.
Optical Performance Comparison

Both the Laowa 20mm and 15mm lenses benefit from Laowa's Zero-D technology, which significantly reduces distortion in wide-angle images. However, the two lenses differ in terms of optical sharpness, chromatic aberration, and bokeh.

  • Sharpness & Resolution: The 15mm lens is sharper across the frame, especially at the corners, making it ideal for landscape shots.
  • Distortion and Chromatic Aberration: Both lenses perform excellently in minimizing these issues.
  • Bokeh: The 20mm lens has slightly better bokeh due to its longer focal length.
Shift Mechanism and Its Use in Photography

The shift mechanism is central to the appeal of these lenses. For architectural photographers, it allows for corrections of perspective, particularly in buildings where vertical lines can distort when photographing tall structures. The Laowa 20mm offers a more generous 11mm shift, while the 15mm offers 10mm. Both are significant for avoiding converging lines in images.

Image Quality and Optical Features

Both lenses exhibit superb sharpness across their aperture ranges. The Laowa 15mm F/4.5 Zero-D Shift excels in landscape shooting, delivering pin-sharp detail even in low light. The Laowa 20mm also handles low light well, though it is slightly less sharp in the corners at wider apertures.

Build and Durability

Both lenses are built to last with weather-sealing and robust metal bodies. However, the 20mm lens is a bit bulkier, which may affect portability when traveling or shooting in the field.

Autofocus and Manual Focus

Both lenses are manual focus-only, which is common in shift lenses. However, they both offer smooth and precise manual focusing, essential for ensuring the sharpest details in architectural photography.

Cost and Value for Money

The Laowa 20mm F/4 Zero-D Shift is priced slightly higher than the 15mm, reflecting its more extensive shift range and slightly higher focal length. However, both lenses offer great value for money in terms of optical performance and build quality.

Best Use Cases for Each Lens

The Laowa 20mm F/4 Zero-D Shift excels in architectural photography, while the Laowa 15mm F/4.5 Zero-D Shift is better suited for landscape photography due to its compact size and wide field of view.

Which Lens is Right for You?

Choosing between the two depends on your specific needs. If you prioritize architectural photography and need a wider shift range, the 20mm lens may be the better choice. However, for those looking for a more portable option for landscape and outdoor photography, the 15mm F/4.5 offers great performance with a more manageable form factor.
