ROKINON 35mm F1.4 AS Wide Angle US UMC Aspherical Lens
Product Information
The product is a lens that is compatible with various camera mounts, including Canon M, Fujifilm X, Sony, Sony E, FT, MFT, NX, and Canon EOS. The lens is available in different versions, including non-CPU lens and AE lens (with an electric contact and built-in aperture operating motor). For the Canon EOS mount, the lens without contacts (non-CPU lens) allows you to adjust the brightness by adjusting the aperture ring manually. On the other hand, the lens with an electric contact (AE lens) enables automatic exposure setting through communication with the camera. There is also a specific lens available for the Canon mount called 35mm F1.4 AS UMC lens (AE version) that comes with a CPU for automatic exposure value calculation.
Product Usage Instructions
Mounting the Lens:
- Ensure that your camera is powered off.
- Align the lens with the camera mount.
- Gently rotate the lens clockwise until it locks into place.
Adjusting Aperture (Non-CPU Lens):
- For Canon EOS mount (non-CPU lens), set the desired aperture value by adjusting the aperture ring on the lens.
- The aperture values range from F1.4 to F2.0 and F16 to F22, based on a 1-stop (1EV) increment.
Automatic Exposure (AE Lens):
- For Canon EOS mount (AE lens) and other compatible mounts, the aperture value is set automatically through communication between the camera and lens.
- This ensures proper exposure based on the available light conditions.
- In M mode (manual mode), you can manually set the aperture value yourself if desired. Refer to your camera’s user manual for detailed instructions on shooting modes.
Optional AE Lens (Canon Mount):
- If you prefer to have automatic exposure with the Canon mount, you can purchase the 35mm F1.4 AS UMC lens (AE version) that comes with a CPU installed.
