As any photographer will know, the sharpness of your focus has a huge impact on your final shot, especially apparent on high-resolution sensors. DSLR auto-focus sensors are separate from the imaging CMOS sensor so there can be a variation between the distance from lens to AF sensor vs lens to CMOS. This variation can cause the AF to lock on even if the image recorded is slightly soft.
Our new focus calibration service matches bodies to lenses for optimal focus performance using FoCal software and the AF fine tune options built into your camera.
Focus calibration is a process used to ensure that the autofocus system of a camera is accurately and consistently focusing on the intended subject. It involves adjusting the camera’s autofocus settings to compensate for any front or back focusing issues.
“FoCal” is an abbreviation of “Focus Calibration,” which is the process of measuring and adjusting the focus performance of a camera and lens system. Reikan FoCal is a system that allows for automatic autofocus calibration, which determines the calibration values required for a user’s camera and lens at the touch of a button.
In addition to focusing calibration, Reikan FoCal also offers a range of other features and tests, including autofocus consistency and accuracy, aperture sharpness, distortion, and advanced testing for expert users.
Some signs that your camera may need focus calibration include consistently blurry or out-of-focus images, especially when using the autofocus feature. If you find that the focus seems inconsistent or that images are consistently front or back-focused, it may be worth considering focus calibration.
While some cameras offer built-in autofocus micro-adjustment features that allow users to perform basic focus calibration themselves, it is generally recommended to have it done by a professional service or authorized camera technician. They have the necessary tools and expertise to accurately calibrate the focus system.
It is generally not necessary to calibrate the focus of your camera frequently unless you notice consistent focus issues. However, lens changes, accidental impacts, or firmware updates can sometimes affect autofocus performance, so it’s a good idea to have your camera calibrated after any significant changes or events.
The time taken for focus calibration can vary depending on the complexity of the camera and the specific issues that need to be addressed. It can range from a few minutes to an hour or more, depending on the situation. It is best to check with the service provider or technician for an estimated time frame.
The cost of focus calibration can vary depending on the camera model, the service provider, and any additional repairs or adjustments that may be needed. It is recommended to contact a professional camera service centre or technician for specific pricing information.
Focus calibration can generally be performed on most DSLR (Digital Single-Lens Reflex) cameras with interchangeable lenses. Mirrorless cameras with interchangeable lenses may also support focus calibration, but it is advisable to consult the camera’s user manual or contact the manufacturer for specific guidance.
Once your camera’s focus has been professionally calibrated, it should remain accurate and stable unless there are significant changes to the camera or lens. However, it is always a good idea to periodically check the focus performance and seek professional calibration if you notice any persistent issues.
In most cases, focus calibration performed by a professional service center or authorized technician will not void your camera warranty. However, it is advisable to check your camera’s warranty terms and conditions or consult with the manufacturer to ensure that calibration does not impact your warranty coverage.
Focus Calibration Procedure
The Fixation calibration service starts with a thorough professional sensor-clean that cleans the sensor, mirror and mirror-box assembly. Dust in the mirror box area can interfere with the auto focus performance and we need a clean slate to start testing and adjusting. Our technicians go the extra mile to ensure the most accurate tests, undertaking the following steps each time:
- Take test images to establish level and location of dust
- Clean the mirror box area, including the underside of the focus screen
- Clean the sensor
- Clean front and rear elements of lenses
- Upgrade your camera to the latest firmware
- Check lenses and cameras for any faults before calibration
- Test each lens and adjust AF fine-tuning using Fo-Cal calibration software
- Email focus performance report with a record of adjustments made
Please note that we may change your camera settings whilst we perform sensor cleaning. Please read our T&Cs for further info. Before and after tests may not show dramatic improvements in focus performance when shooting wide open as many lenses are softer at their widest apertures.
How Does Focus Calibration Work?
Focus calibration is an adjustment to correct front focus or back focus. This is where the sharp area of your image falls just in front of, or just behind, where you intended to focus. Calibration tells the camera that for a specific lens the focus should be pushed back or forwards a little to compensate for this inaccuracy. Canon calls this setting AF micro adjustment while Nikon calls it AF fine tune. We test each of the lenses you supply with each of your camera bodies at every focus adjustment position to identify the best focus position for each camera and lens combination.
How Often Should I Have My Cameras And Lenses Calibrated?
We are often asked how often servicing and calibration is needed. There is no one answer to this question as it depends on the frequency of use and working environment that your camera is exposed to. Subtle changes in image sharpness can build up over time, we recommend you keep track of your camera’s performance by comparing images with a similar shoot that you did in the past. Remember that the adjustment is specific to each camera and lens combination so you may experience different results using one lens on different camera bodies.
