Samyang 300mm F6.3 Reflex peiliteleobjektiivi Sony E (hopea)

For photographers who want extreme telephoto reach without the bulk, the Samyang 300mm F6.3 Reflex lens offers a mirror-based optical design that is dramatically smaller and lighter than conventional refractive 300mm lenses. Its fixed f/6.3 aperture and manual focus demand a deliberate shooting style, but reward you with a unique donut-shaped bokeh and a compact package that fits easily in a small bag. The silver metal barrel not only looks distinctive but also helps reflect heat, keeping the lens cooler during long outdoor sessions.

Highlights

• 300mm focal length on Sony E-mount APS-C cameras (450mm equivalent full-frame field of view)
• Reflex (catadioptric) design: only 62mm long and 64.5mm in diameter
• Fixed f/6.3 aperture – no diaphragm, exposure controlled via shutter speed or ISO
• UMC multi-coating and ED element reduce flare, ghosting, and chromatic aberration
• Manual focus with smooth, precise ring; minimum focus distance 0.9m
• 58mm front filter thread and 25.5mm rear filter slot for creative effects
• All-metal construction for durability and premium feel

In daily use

This lens is ideal for wildlife, sports, and astrophotography where you can work with a tripod or fast shutter speeds. The mirror design eliminates chromatic aberration almost entirely, and the fixed aperture means you will rely on ISO and shutter speed for exposure. The manual focus ring is well-damped, and the lens includes a built-in lens hood to reduce stray light. Because of the mirror design, out-of-focus highlights take on a distinctive ring shape, which can be used creatively. The silver finish is not just cosmetic – it helps keep the lens cooler in direct sunlight, which is beneficial for long shooting sessions.
