NiSi 250mm F5.6 Reflex MF Lens

Description

• Appropriate depth of field: Aperture F5.6 is a “golden match” for the 250mm segment. If the focal length is too short, the depth of field is too large and the background blur is not obvious, the donut and bilinear characteristics are not strong.
• The donut is more prominent, with a “better proportion” of rings, good shallow depth of field, and clear donuts from minimum to maximum size, resulting in a richer layering.
• The bilinear characteristics outside the focus are more pronounced, with a painterly brushstroke feel.
• Special optical glass material and coating design, the image is transparent, with a slight warm tone, vivid colors, a comfortable retro tone, soft, stable, clean imaging, and a more atmospheric oil painting feel.
• The focus travel is increased to 270 degrees of movie lens, which makes focusing more precise, easier, and quicker to get started.
