Solve Hard-to-Diagnose Temperature Related Problems

With the Temperature Plugin, you can:

1. Check and Test Key Sensors; on the Shutter, CMOS, Main PCB, and TFT Display Cover.
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.

Sharp Focus: Calibrating the Lens to Your Camera Body

Get the sharpest Auto Focus from your customers Lens by Paring it to their Camera Body

Adjusts both Lens and Lens + Extender

With the Lens Focus Calibration Plugin, you can:

1. Offer a standalone Auto Focus Adjustment Service to address common autofocus issues.
2. Pair your customers lens to their camera body for optimized autofocus.
3. Adjust both Prime (fixed focal length) and Zoom lenses for precision performance.
4. Adjust both Wide and Telephoto settings on Zoom lenses.
5. Adjust AF for Lenses used with Extenders
6. The Canon R5, R6, R7 and R-10 can register up to 7 lenses to the camera body for streamlined operation.
7. Add or remove lenses as needed, allowing for flexible customization.
8. View a color-coded list of lenses, including those that are Registered but not attached, Attached but not yet Registered, and Currently attached and Registered for quick and efficient management.

Sharper Auto Focus

Soft autofocus is a common complaint among mirrorless camera owners. Many photographers find that while some lenses focus perfectly, others may front- or back-focus on the same camera body, producing soft images.

This isn’t a flaw in the camera or the lens — it’s the result of that specific lens–body combination.

With the Auto Focus Calibration Plugin, you can easily fine-tune each lens to the customer’s camera body, restoring sharp, accurate focus. The process is simple and efficient — just the camera, lens, and the standard 3D target included with the software.

This plugin offers a fast, effective way to expand your service capabilities and deliver precision results that customers can see.

New: Many users noticed that images were perfectly sharp without an extender but softened when one was attached. The latest Pro Advanced upgrade now solves this by allowing separate AF adjustments for each setup — with and without extenders.

Save Yourself Trouble Later — Use the Calibration Tab in Essential First

Before doing anything else, we recommend backing up your camera’s Calibration Data using the Calibration Data Tab in Essential. It’s the simplest and most direct way to save your data—and it gives you an easy-to-access backup for the future.

While the Main Board Replacement Plugin also saves Calibration Data, it’s part of a larger, more complex process, and the camera data backup file it creates is stored in a hidden folder. That makes it harder to find or use later if you need it.

Bottom line:
Start with the Calibration Tab in Essential. It’s quicker, easier, and gives you a clean backup you can rely on if something goes wrong down the road.

A Practical Solution When a Known Good Reference Camera Is Not Available

For the most accurate CMOS calibration, it’s ideal to use a working camera of the same model — preferably one that is brand new or has never been repaired and is known to function correctly.

But sometimes, you don’t have access to a known good camera — especially when working with used gear, salvaged parts, or equipment that’s already been repaired. In these cases, being able to create a Demo-based compensation file allows you to move forward with CMOS calibration, even without the ideal setup.

What Is the Demo File?

The Demo feature creates a simulated compensation file using ideal values — as if you were using a perfectly calibrated light source and a standard EF 50mm F1.8 STM lens. While not as precise as a real-world calibration, this method usually gives better results than the generic calibration stored on a replacement main board.

How to Create a Compensation File Using Demo

1. Close the SPT software completely and then reopen it.
2. In the first window that appears, click ‘Demo’.
3. Go to the Plugins tab and select CMOS Calibration.
4. Under the Lightbox/Lens Compensation tab, follow the steps—this mostly involves clicking ‘Start’ several times.
5. When prompted, save the compensation file.

Using the Demo File for CMOS Calibration

When you use this file for CMOS calibration, the SPT software will detect that it's a Demo file and ask you to confirm before proceeding. This is just a safeguard to make sure you understand that it’s not as precise as calibration with a real camera.
