Compatibility & Setup Instructions

This is a fully manual T-Mount lens—your camera cannot electronically detect or communicate with it. Before use, follow these steps:

• Set both your camera and lens to Manual (M) Mode
• In your camera menu, enable “Release Shutter Without Lens” or “Allow Shutter Release Without Lens” (exact wording varies by model)
• We recommend using Live View for precise manual focusing
• This lens does not support image stabilization, displays no aperture value on-camera, and does not record lens metadata in EXIF

Usage Tips

• Focusing: Rotate the front focus ring slowly and precisely; for critical sharpness, pair with Live View zoom
• Stability: Due to its long focal length and lack of built-in stabilization, we strongly recommend using a sturdy tripod and remote shutter release
• Exposure Control: Adjust shutter speed and ISO manually:
  • If the image is too dark: decrease shutter speed (e.g., from 1/125s to 1/60s) and/or increase ISO
  • If the image is too bright: increase shutter speed (e.g., from 1/125s to 1/250s) and/or decrease ISO

Included & Optional Adapters

This package includes a T-Mount to Canon EF adapter. For other mounts, purchase compatible T-Mount adapters separately:

• Nikon F mount: T-Mount to Nikon F adapter (sold separately)
• Pentax K, Sony A/FE, Fujifilm X, Micro Four Thirds: Select the corresponding T-Mount adapter
