Temperature

Solve Hard-to-Troubleshoot Temperature Related Problems

With the Temperature Plugin, you can:

  1. Check and Test Key Sensors; on the EF Unit, CMOS Unit, TFT Display.
  2. Eliminate guesswork when diagnosing temperature sensor issues.
  3. Quickly identify the source of temperature-related problems.
  4. Save time and minimize frustration during repairs.

 

Here are a few temperature-related issues

  • Soft focus on hot days – Caused by changes in Lens Flange/CMOS distance.
  • Random overexposure or underexposure – Due to fluctuations in AE current.
  • Dark images at high shutter speeds – Resulting from Shutter temperature changes.
  • Flash malfunctions – Triggered by temperature shifts in the EF unit.

Canon 5D Mark IV Lens Focus Compensation & AF Error Diagnostic

⬅️ Tip: Use your browser’s back arrow to return to the previous page anytime.

Lens Focus Compensation Plugin

Measure Lens AF Error Values to Recalibrate Lenses AF in SPT Lens Professional

How Lens Focus Compensation Works

This plugin automates a series of camera AF operations to measure a lens's average deviation from perfect focus, generating a precise Lens Focus Error number.

You can then input this value into SPT Lens Professional Software to perform true lens AF adjustments.

  • Automated Focus Analysis: Measures exact focus deviation across specific AF system configurations and zoom settings.
  • Isolate Mechanical vs. Calibration Issues:
    • Small Errors: Normal tolerance; can generally be ignored.
    • Larger Errors {> 0.04): Indicates either an internal mechanical fault or a lens that requires full recalibration.
  • Bench Requirement: Must be used with a verified Reference Body that shares the target camera's AF system.

With the Camera Data Tab, you can:

  1. Replace the Main Board with a reliable Used board, if you were able to save the original Calibration data.
  2. Save the calibration data before making adjustments, so you can quickly restore the camera’s original settings if needed.

 

⚠️  If you CAN NOT save the Original Camera Data or are installing a New Main Board, you will need to use the more extensive Main Board Replacement Plugin.

 

ℹ️ Note on AF MacroAdjust: These files contain the custom lens-to-body focus compensation data. They are saved automatically inside your full Calibration Data backup, or can be managed as individual files.

 

The software makes it simple … just follow the directions and prompts

Canon DSLR Manual Auto Focus Calibration Overview
Automatic AF Calibration | Manual AF Adjustment | Sensor Output
Manual Auto Focus Adjustment

Our automatic calibration process handles most jobs and is the recommended default method!

However, Technician preference or unique client requests — such as specific front/back shifts or Infrared (IR) conversions require manual AF Adjustment. For these advanced setups, you will use the Enable Sensors and AF Shift tabs in tandem to dial in the calibration.

Bench Tip: Until you are experienced with manual sensor-level calibration, we strongly recommend selecting "Enable all sensors (Normal)" in the Enable Sensors tab, and Adjust 'All sensors' in the AF Shift tab.

Enable Sensors (Requires Test Lens)

Manually AF Adjustments are normally reserved for special calibrations!
Select Enable all sensors (Normal) for standard repairs.
Click: "All sensors (Normal)". This locks all sensor groups simultaneously so you can adjust them globally inside the AF Shift tab.

Manual AF Adjustment — Part 2 (Requires Test Lens)

Use this tab to manually adjust AF shift values after enabling your sensors.
Reserve Manual AF Adjustments for Special Calibrations Only.

Getting Started

Start by creating a Calibrated Test Lens. This gives you a hands-on introduction to the workflow, and this single lens can be used to service all Canon DSLR bodies. Use the software Help section to select a good test lens.

When performing a repair, use this fast two-step workflow:

  1. Backup Camera Data using the Backup tab.
  2. Calibrate Auto Focus automatically using the AF Calibrate tab.

AF Data Backup & Restore

Protect the camera’s original calibration data before Making any modifications

Create a Test Lens

Create a calibrated Test Lens by building a custom compensation file.
Normally AF calibration requires an expensive, lab-grade lens. Our process creates a custom compensation file for a standard, high-quality lens; converting it into a precise Test Lens.
You can create as many Test Lenses as you want.
Watch & Learn: How to Build Your Test Lens

Automatic AF Calibration (Requires Test Lens)

Adjust your Camera Bodies AF Automatically
Cameras have hundreds of AF Sensors, so it is not practical to calibrate AF manually. SPT Software uses our Automatic AF Calibration process which can complete the job in minutes.
Load your saved Compensation File into your Test Lens. Then follow our step-by-step on-screen prompts to manually guide software as it adjusts the camera body.

⚠️ Tip:  Even though you are planing to use the Main Board Replacement plugin,  save your Camera Data using the Calibration Tab first,  Here’s why …

With the Main Board Replacement Plugin, you can:

  • Replace the defective Board with a new Main Board
  • Use a Reliable used Main Board even if the original Calibration Data was not saved.

This Backup Calibration tab goes beyond the Calibration Data tab in Essential — it captures a more complete set of data, including files stored on other boards inside the camera.

 

⚠️ IMPORTANT: Canon OEM Battery Power Issue There are verified reports of new main boards failing to power up when using a Canon OEM battery. This issue does not occur with third-party/off-brand batteries.

⚠️  Users report having successfully installed calibration data from a similar model with good results. However, installing non-original calibration data is not fully tested. Proceed at your own discretion.

 

⚠️ Important: User Data must be saved and restored separately. User Settings are NOT part of Calibration Data or Backup Calibration.
