Sony SEL28F20

Overview

The Sony SEL28F20 is a compact wide-angle prime lens designed for full-frame E-mount cameras, offering a 28 mm focal length and a bright f/2 aperture. This lens excels in low-light conditions and provides a shallow depth of field to make subjects stand out with smooth background blur. Its lightweight design, weighing about 200 grams, makes it an excellent choice for photographers and videographers who need high optical performance without added bulk.

Key features

• Bright f/2 maximum aperture allows shooting in dim environments and creates a shallow depth of field for subject isolation.
• Two extra-low dispersion elements combined with three aspherical elements reduce chromatic aberration and edge distortion, ensuring sharp and true-to-life images across the frame.
• Fast and quiet autofocus driven by a linear motor supports both still photography and video recording without distracting noise.
• Dust and moisture-resistant construction provides reliability for outdoor shooting in challenging weather conditions.
• 9-blade rounded diaphragm produces smooth, circular bokeh that enhances the aesthetic quality of out-of-focus areas.
• Compatibility with Sony’s optional Ultra-Wide and Fisheye conversion lenses expands creative possibilities without the need for additional lenses.
• Compact and lightweight build balances naturally on Sony A7 series cameras and fits easily into travel kits or small bags.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
