Premier third-party lens manufacturer Sigma has drawn strong interest across the industry by disclosing patents for two new full-frame super-zoom lenses designed for E-mount and L-mount mirrorless systems.
According to global news outlet SonyAlphaRumors, these patent disclosures outline high-performance optical designs aimed directly at photographers seeking the ultimate single-lens, all-in-one setup for travel and everyday walkaround shooting.
Here is a breakdown of the key specifications and features revealed in Sigma's newly disclosed lens patents.
1. Key Specifications of the Two Disclosed Sigma Super-Zoom Lens Patents
- 28-200mm F3.5-5.6: A standard high-resolution all-in-one zoom covering wide-angle 28mm to telephoto 200mm. It combines a versatile F3.5-5.6 variable aperture with a compact form factor designed to maximize optical quality for travel and snapshot photography.
- 28-300mm F3.5-6.3: An extended super-telephoto zoom lens offering an immense focal range. Its optical construction incorporates multiple specialized glass elements to correct aberrations across the entire range, handling everything from landscapes to wildlife and sports in a single package.
2. Advanced Optical Architecture to Overcome Traditional Super-Zoom Limits
- Heavy Use of Low-Dispersion Glass (FLD/SLD): Incorporates advanced aberration-correction element groupings to drastically suppress chromatic aberration and corner softness—longstanding drawbacks of traditional super-zoom optics at telephoto focal lengths.
- Multi-Mount Compatibility for E-Mount & L-Mount: Highly likely to enter mass production under Sigma’s Contemporary or Art lineups, promising a versatile all-in-one solution for both Sony Alpha users and Panasonic/Leica/Sigma L-mount photographers.
✍️ Editor's Note
"Whenever we head out for travel or light outdoor excursions, we always ask ourselves: 'Can I just get away with bringing one single lens?' While traditional 28-200mm or 28-300mm super-zooms often required trade-offs in image sharpness, seeing Sigma apply its modern optical engineering to these patent formulas gives us plenty of reason to be excited! If Sigma brings its signature edge-to-edge sharpness to a light all-in-one zoom, it could completely redefine travel lens lineups for mirrorless shooters!"
