Zeiss Loxia 50mm — same as ID 597, possible duplicate with different canonical name.
The Zeiss Loxia 50mm f/2 Planar T* for Sony E mount is a premium manual-focus standard prime using the classic Zeiss Planar optical formula. It is the same lens as ID 597 with a different canonical name emphasising the Sony E compatibility.
Same outstanding Planar T* optics as ID 597 — smooth tonal transitions with Zeiss rendering character. Weather-sealed construction with de-clickable aperture ring for video use. Electronic EXIF contacts communicate focus distance and aperture data to the camera body.
Sony FE mount with 52mm filter thread at 320g with full weather sealing — unusual for a manual-focus prime. Minimum focus distance 37cm. The de-clickable aperture enables smooth iris transitions for professional video production work.
Available used at mid-range to professional prices. This listing appears to be a duplicate of ID 597 with explicit Sony E mount designation. The Loxia range targets manual-focus enthusiasts on Sony FE who value the tactile shooting experience and Zeiss rendering.
