Using Live View for Focusing
In Live View mode, you can focus manually using the magnified image on the LCD screen. This allows for precise focusing, especially when shooting macro or landscape images.
Manual Focusing
For maximum control, you can switch to manual focus (MF) mode. Use the focus ring on the lens to adjust the focus manually. This is particularly useful for shooting in low-light conditions or when focusing on specific details.
Focus Lock and Recompose
This technique allows you to focus on a subject and then recompose the frame without losing focus. To do this, press the shutter button halfway to lock focus, then recompose and fully press the shutter button.
Focus Fine-Tuning
If you notice consistent focusing errors, you may need to fine-tune the autofocus system. This can be done through the camera’s menu system.
Tips for Sharper Focus
- Use a tripod for stability.
- Avoid shooting in low-light conditions if possible.
