Additional information on the Schneider Kreuznach × LK Samyang lens prototypes

Here is some additional information on the Schneider Kreuznach × LK Samyang lens prototypes (previously reported here), courtesy of Phototrend from their CP+ report:

Focal length & aperture: 20-50 mm f/2 (constant)
Mount: Sony E (FE)
Key points: Brighter and wider than the existing AF 24-60 mm f/2.8; expected to be bulkier and heavier
Status: Very early development (possible 2028–2029 launch to avoid cannibalising the 24-60 mm)
No further specs (elements/groups, size, weight, etc.) available yet

Focal length & aperture: 28-85 mm f/2-2.8 (variable aperture; originally planned constant f/2 but adjusted for size)
Mount: Sony E (FE)
Key points: Slightly larger than the new AF 24-60 mm f/2.8; no built-in stabilisation
Status: Early concept; possible late-2027 or spring-2028 release if feedback is positive
No further specs released

Focal length & aperture: 28-135 mm f/2.8 (constant)
Mount: Sony E (FE)
Key points: New linear VCM autofocus motor (faster and quieter than previous stepper motors, ideal for video/action); more versatile range than competing 28-105/35-100 mm f/2.8 zooms
Status: Already in production; prototype shown at IBC 2025; earliest release late 2026
No detailed optical formula, size or weight figures yet

Focal length & aperture: 300 mm f/4
Mount: Sony E (FE)
Key points: First Samyang lens with optical image stabilisation (OIS); built-in 1.4× teleconverter (becomes 420 mm f/5.6); multiple custom controls; positioned as a lighter/cheaper wildlife/sports alternative to 70-200 mm f/2.8 zooms
Status: Early development; competitive pricing targeted
No further specs available

Focal length & aperture: 200 mm f/1.8
Mount: Sony E (FE)
Key points: Bright prime with integrated OIS; technological showcase to compete with Laowa/Sigma 200 mm f/2 options
Status: Early development (only one of the two telephoto primes may eventually be produced to avoid internal competition)
No further specs released

In the US, some LK Samyang lenses are sold under the Rokinon brand. In Europe, Smyang lenses are sold at Foto Erhardt and WEX Photo.
