7artisans 50mm F0.95 APS-C Manual Focus Prime Lens Instruction Manual

1. Product Overview

The 7artisans 50mm F0.95 lens is a large aperture manual focus prime lens designed for APS-C mirrorless cameras with a Sony E-Mount. It is engineered to provide a shallow depth of field and smooth background blur, making it suitable for portrait, street, and creative photography. Its optical design allows for clear images even in low-light conditions.

Key Features:

• Ultra-Large F0.95 Aperture: Designed for shallow depth of field and smooth bokeh, ideal for subject isolation.
• Low-Light Performance: The wide F0.95 aperture allows significant light intake, enabling clear images with lower ISO settings in dim environments.
• Optical Construction: Features 7 elements in 5 groups, including 2 ED (Extra-low Dispersion) glass elements, and 13 aperture blades for high image quality and pleasing out-of-focus areas.
• Manual Focus: Provides precise control over focus, with a minimum focusing distance of 0.45 meters.
• APS-C Compatibility: Offers an angle of view equivalent to approximately 75mm on full-frame cameras.

3.2 Camera Settings for Manual Lenses

Since this is a manual lens without electronic contacts, your camera may not detect its presence. To enable shooting, you might need to adjust a specific camera setting. This setting is commonly referred to as "Release shutter w/o lens" or similar.

Image 3.2: Example camera menu settings for enabling shutter release without a lens. Consult your camera's manual for exact steps.

General Steps (may vary by camera model):

• Navigate to your camera's menu.
• Look for settings related to "Shooting," "Custom Settings," or "Setup."
• Find an option like "Release shutter w/o lens," "Shoot without lens," or "Shutter Lock."
• Enable this option (set to "On" or "Disable" shutter lock).

Refer to your specific camera's instruction manual for precise menu navigation and terminology.

4. Operating the Lens

The 7artisans 50mm F0.95 is a fully manual lens, requiring manual control of both focus and aperture.

4.1 Manual Focusing

• Focus Ring: Rotate the focus ring (labeled with distance markings in meters and feet) to adjust the focus. Turn it until your subject appears sharp in the viewfinder or on the LCD screen.
• Focus Peaking/Magnification: Utilize your camera's focus peaking and/or magnification features for more precise manual focusing. These tools highlight in-focus areas or zoom into the image for critical focus.

4.2 Aperture Control

• Aperture Ring: The lens features an aperture ring (marked with F-stops from F0.95 to F16). Rotate this ring to select your desired aperture.
• De-clicked Aperture: This lens has a de-clicked aperture ring, meaning it rotates smoothly without distinct stops. This is beneficial for video recording as it allows for seamless aperture adjustments during shooting.
• Depth of Field Scale: The depth of field scale on the lens barrel provides an indication of the range of acceptable sharpness at different apertures and focus distances.

4.3 Exposure Settings

Since the lens does not communicate aperture information to the camera, you will need to set your camera to Manual (M) mode or Aperture Priority (A/Av) mode. In Manual mode, you control shutter speed, ISO, and aperture. In Aperture Priority, you set the ISO and shutter speed, and the camera will adjust the shutter speed for correct exposure based on the aperture you set on the lens.

4.4 Optical Structure and Performance

The lens's optical design, featuring 7 elements in 5 groups with 2 ED glasses, contributes to its image quality. The 13 aperture blades create a smooth, circular bokeh, enhancing the aesthetic appeal of out-of-focus areas.

5. Care and Maintenance

• Cleaning the Lens: Use a soft, lint-free microfiber cloth specifically designed for optics to clean the lens elements. For stubborn smudges, use a small amount of lens cleaning fluid applied to the cloth, not directly to the lens.
• Dust Removal: Use a blower brush to remove dust particles from the lens surface before wiping. Avoid using compressed air, which can damage coatings or force dust into the lens.
• Storage: When not in use, keep the lens covered with both front and rear caps. Store it in a dry, cool place, ideally in a lens pouch or camera bag to protect it from dust, moisture, and impacts.
• Avoid Extreme Conditions: Do not expose the lens to extreme temperatures, high humidity, or direct sunlight for extended periods. The lens is not water-resistant.
