6. Objektifin Kullanımı
6.1 Manual Focus
The Irix 11mm f/4.0 Firefly is a manual focus lens. Rotate the focus ring to adjust the focus. The built-in AE chip provides focus confirmation through your camera's viewbulucu veya canlı view, indicating when your subject is in sharp focus.
6.2 Infinity Click
The lens features an audible and tactile 'infinity click' that helps you quickly set the focus to infinity without needing to look at the focus scale. This is particularly useful for astrophotography or landscape shots where distant subjects need to be sharp.
Video: Demonstration of the Irix lens infinity click feature. This video shows the feature on a 15mm lens, but the functionality is identical for the 11mm lens.
6.3 Hyperfocal Scale
Utilize the hyperfocal scale on the lens barrel to maximize depth of field. By setting the focus to the hyperfocal distance, you can achieve sharp focus from half that distance to infinity.
6.4 Diyafram Kontrolü
Thanks to the built-in AE chip, the aperture of the Irix 11mm f/4.0 Firefly lens can be controlled directly from your camera body, just like an autofocus lens. This allows for seamless integration with your camera's exposure modes.
7. Bakım
7.1 Lensin Temizlenmesi

8. Sorun Giderme
| Sorun | Olası Neden | Çözüm |
|---|---|---|
| Difficulty achieving sharp focus | Incorrect manual focus setting. | Utilize your camera's focus peaking or magnification features for precise manual focusing. Ensure the focus lock ring is disengaged. |
| Aperture not controllable from camera | Poor contact between lens and camera. | Ensure the lens is securely mounted. Clean the electronic contacts on both the lens and camera with a dry, soft cloth. |
| Purple fringing or color aberrations | Common with ultra-wide lenses, especially in high-contrast areas. | These can often be corrected in post-processing software (e.g., Lightroom, Photoshop) using chromatic aberration removal tools. |
| Lens feels loose on camera mount | Lens not fully engaged. | Re-mount the lens, ensuring it clicks securely into place. |
