The Options in Focus Compensation will be different depending on the Lens and AF system! The software will automatically adapt and offer only the options applicable to your Lens.
Start by selecting ‘All Cameras’ and ‘Aria 61-Frame’.
- ‘All Cameras’ gives accurate AF compensation across all camera bodies, while ‘Aria 61-Frame’ supports ‘Convert to Other AF Systems’, which lets your adjustments apply automatically across the board.
- ‘Selected Camera Models’ and ‘Select AF System to Adjust’ options are for special situations, which are fully explained in both the Demo and working software instructions.
⚠️ The Help files in the working software and Demo will guide you through every step: when to adjust, which targets to use, and how to save and verify results.
Example: Creating a Focus Compensation File
- Select All Cameras
- Select Aria 61-Frame – to open the AF Compensation window.
The necessary AF targets are included with the software!
Area 61-Frame
This menu is used to create the F/2.8 and F/5.6 AF Sensors Compensation Files.
Compensation Adjustment is a Two Step Process:
- Click F/2.8 to adjust the f/2.8 sensors using Diagonal targets.
- Click F/5.6 to adjust the f/5.6 sensors using Vertical and Horizontal targets.
F/2.8 Focus Compensation Adjust
This menu lets you adjust the f/2.8 AF sensors, creating the F/2.8 Compensation File.
Step 1: Create the F/2.8 Compensation File
- First test the Lens and record the initial AF error.
- Then make adjustments using the Diagonal targets at both telephoto and wide-angle zoom positions.
- Using the ‘Calculate Intermediate Values’ button you automatically fill in the adjustments for the other zoom steps.
- Now click “Write the New Values” to create the new F/2.8 Compensation data File.
- Finally, you test the lens again to verify improved focus accuracy. And move on to creating the F/5.6 Compensation File.
F/5.6 Focus Compensation Adjust
This menu lets you adjust the f/5.6 AF sensors, creating the F/5.6 Compensation File.
Step 2: Create the F/5.6 Compensation File
You follow the same process as the F/2.8 file, using the Vertical and Horizontal targets to adjust the f/5.6 AF sensors. When finished, the workflow returns through the Area 61-Frame window to Focus Compensation Adjustment window, where you use the ‘Convert to Other AF Systems’ function to complete the process.
