When it comes to photography, autofocus is one of the most crucial features that can make or break a shot. With the advancements in technology, camera manufacturers have introduced various autofocus modes and settings to help photographers achieve precise focus. Two such features that often raise questions among photographers are AEL (Auto Exposure Lock) and AF MF (Autofocus Manual Focus). In this article, we’ll delve into the world of autofocus and explore what AEL and AF MF are, how they work, and when to use them to take your photography skills to the next level.
What is AEL (Auto Exposure Lock)?
AEL, or Auto Exposure Lock, is a feature found in many cameras that allows photographers to lock the exposure settings for a scene, ensuring that the camera captures the desired brightness and contrast. This feature is particularly useful when shooting in challenging lighting conditions or when the subject is backlit.
How AEL Works
When you activate AEL, the camera takes a meter reading of the scene and locks the exposure settings, including aperture, shutter speed, and ISO. This means that even if the lighting conditions change, the camera will maintain the same exposure settings, ensuring consistency in the captured image.
For example, imagine you’re shooting a portrait of a person standing in front of a bright window. Without AEL, the camera might adjust the exposure settings to compensate for the bright background, resulting in an underexposed subject. By activating AEL, you can lock the exposure settings to prioritize the subject’s face, ensuring it’s properly exposed.
Benefits of AEL
The benefits of AEL are numerous:
- Consistency in exposure: AEL ensures that the camera captures the desired exposure settings, even in changing lighting conditions.
- Prioritizes subject: By locking the exposure settings, you can prioritize the subject’s face or a specific area of the image, ensuring it’s properly exposed.
What is AF MF (Autofocus Manual Focus)?
AF MF, or Autofocus Manual Focus, is a feature that combines the benefits of autofocus and manual focus. This feature allows photographers to use the camera’s autofocus system to quickly acquire focus and then fine-tune the focus manually using the lens’s focus ring.
How AF MF Works
When you activate AF MF, the camera’s autofocus system quickly locks onto the subject and adjusts the focus accordingly. However, instead of relying solely on the autofocus system, you can then manually adjust the focus using the lens’s focus ring. This allows for precise control over the focus point, ensuring that the subject is tack-sharp.
For example, imagine you’re shooting a macro shot of a delicate flower. The autofocus system might struggle to lock onto the subject, resulting in a soft focus. By activating AF MF, you can quickly acquire focus using the autofocus system and then fine-tune the focus manually to ensure the desired level of sharpness.
Benefits of AF MF
The benefits of AF MF include:
- Precision focus control: AF MF allows for precise control over the focus point, ensuring that the subject is tack-sharp.
- Combines autofocus and manual focus benefits: AF MF combines the speed and convenience of autofocus with the precision of manual focus.
When to Use AEL and AF MF
Now that we’ve explored what AEL and AF MF are, let’s discuss when to use these features to take your photography to the next level.
Using AEL
Use AEL in the following scenarios:
- Backlit subjects: AEL helps to prioritize the subject’s face or a specific area of the image, ensuring it’s properly exposed.
- Challenging lighting conditions: AEL ensures consistency in exposure, even in changing lighting conditions.
Using AF MF
Use AF MF in the following scenarios:
- Macro and close-up photography: AF MF allows for precise control over the focus point, ensuring that the subject is tack-sharp.
: AF MF ensures that the subject’s eyes are in sharp focus, while the background remains blurred.
Conclusion
AEL and AF MF are two powerful features that can elevate your photography skills and help you achieve stunning images. By understanding how to use these features, you can take control of the autofocus system and ensure that your images are sharp, well-exposed, and visually stunning. Remember, practice makes perfect, so experiment with AEL and AF MF to unlock the full potential of your camera and take your photography to new heights.

By mastering AEL and AF MF, you’ll be able to tackle even the most challenging photography situations with confidence and precision. So, go ahead and experiment with these features – your camera (and your photography skills) will thank you!
What is AEL and how does it differ from AF?
AEL stands for Auto Exposure Lock, which is a feature in digital cameras that allows you to lock the exposure settings, such as aperture, shutter speed, and ISO, to a specific value. This is different from AF, or Autofocus, which is a feature that allows the camera to automatically adjust the focus of the lens to ensure that the subject is in sharp focus. While AF is concerned with focus, AEL is concerned with exposure.
In practice, AEL is useful when you’re taking multiple shots of the same scene, but the lighting conditions are changing. By locking the exposure settings, you can ensure that the brightness and contrast of the images remain consistent. This can be particularly useful in situations where you’re taking a series of shots for a panoramic image or when you’re shooting in a studio setting.
What is AF MF and how does it work?
AF MF, or Autofocus Manual Focus, is a feature that combines the benefits of autofocus and manual focus. When enabled, the camera will initially use autofocus to quickly focus on the subject, and then allow you to manually fine-tune the focus using the lens’s focus ring. This allows you to take advantage of the speed and accuracy of autofocus, while still having control over the final focus.
In practice, AF MF is useful when you need to focus on a subject that is too small or too close for the autofocus system to accurately detect. By using autofocus to get close to the correct focus, and then manually fine-tuning the focus, you can ensure that your subject is sharp and in focus. This feature is particularly useful in macro and close-up photography, where precise focus is critical.
How do I enable AEL on my camera?
The process for enabling AEL on your camera varies depending on the make and model of your camera. However, in general, you can enable AEL by pressing the AEL button, which is usually located on the back or top of the camera. Some cameras may require you to press and hold the AEL button, while others may require you to press it in combination with another button.
Once you’ve pressed the AEL button, the camera will lock the exposure settings, and you’ll often see an “AEL” or “AE Lock” indicator on the camera’s LCD screen or viewfinder. You can then take multiple shots, and the camera will use the locked exposure settings for each shot. Be sure to check your camera’s manual or online documentation for specific instructions on how to enable AEL on your particular camera.
Can I use AEL and AF MF together?
Yes, you can use AEL and AF MF together to take advantage of the benefits of both features. When you enable AEL, the camera will lock the exposure settings, and then when you enable AF MF, the camera will use autofocus to quickly focus on the subject, and then allow you to manually fine-tune the focus. This can be particularly useful when you’re shooting in a situation where the lighting conditions are changing, but you also need precise control over the focus.
By using AEL and AF MF together, you can ensure that your images have consistent brightness and contrast, while also being in sharp focus. This can be particularly useful in situations where you’re shooting a series of shots, such as in a studio setting or when taking a panoramic image.
Is AEL the same as exposure compensation?
No, AEL and exposure compensation are not the same thing. Exposure compensation is a feature that allows you to adjust the brightness of the image by adjusting the aperture, shutter speed, and ISO. This is usually done by adjusting the exposure compensation dial or button on the camera.
AEL, on the other hand, locks the exposure settings to a specific value, so that the camera uses the same settings for multiple shots. While exposure compensation allows you to make adjustments to the brightness of the image, AEL ensures that the brightness and contrast of the image remain consistent across multiple shots.
Can I use AF MF in continuous autofocus mode?
Yes, you can use AF MF in continuous autofocus mode. In continuous autofocus mode, the camera will continuously track the subject and adjust the focus as needed. When you enable AF MF in continuous autofocus mode, the camera will use the autofocus system to track the subject and make any necessary adjustments, and then allow you to manually fine-tune the focus as needed.
This can be particularly useful when you’re shooting fast-moving subjects, such as wildlife or sports, where the subject is constantly moving. By combining continuous autofocus with AF MF, you can ensure that your subject is in sharp focus, even when it’s moving quickly.
Is AF MF available on all cameras?
No, AF MF is not available on all cameras. While many modern digital cameras offer AF MF, some entry-level cameras or older models may not have this feature. Additionally, some cameras may have a similar feature, but it may be called something different, such as “AF+MF” or “Autofocus Fine-Tune”.
If you’re considering purchasing a camera and want to make sure it has AF MF, be sure to check the camera’s specifications or documentation before making a purchase. You can also check online reviews or ask other photographers who have used the camera to see if they have any experience with the AF MF feature.
