Understanding the Canon 5D MK II Internal Shutter Count
Service Advisory from Canon regarding the Canon 5D MKII Shutter Count 
 
Problem
The shutter reading in the General Page of the software can be inaccurate by up to 2048 shots.  This is the camera’s  Internal Shutter Count.
 
 
Reason:
The 5D II has a firmware bug that limits the accuracy of its shot count and total count, read or written, to within 2048 of the actual value. Since the internal shutter count was never designed to display its count to the user, it doesn't have much effect on them until they come in for service.  Because of that Canon did not feel it necessary for an update to correct this defect. 
 
 
You can verify the shutter count:
SPT software are definitely reading and writing the count correctly. We have been able to verify this by comparing to the camera's own built-in shutter count, accessible under the factory menu (DATA CK > ERR), which gives exactly the same results as the SPT Software.
 
 
Technical:
The EOS 5d II stores the correct count until it gets above intervals of 2048 (800 in hexadecimal). Then it just fails to write the current count to Eeprom, until it gets to the next interval, which is 4092, and so on.  It updates an internal counter, so the camera is able to maintain a shutter count, and if you click the shutter enough times, it will start reading correctly again (It'll just jump up by 2048). 
 
 
Keep checking for Firmware Upgrades, Canon may address this issue at some point.
 
Understanding Canon's USB 2 and USB 3 Connectors

Canon uses USB cables to connect their camera’s to PCs.  Although most Canon D SLRs use USB 2 cables known as a ‘micro-USB’,  newer Canon D SLRs have upgraded to USB 3. 

 

USB 2_‘micro-USB’

 

USB 3

 

An easy way to tell USB 3 from USB 2 is that the plastic tongue of the connector is always blue on a USB 3.

 

SPT Service Adjustment Software can use either USB 2 or USB 3 to connect SPT software to the camera …. with the exception of the Canon EOS 5DS and 5DS R.

 

Canon 5D S using the USB 3

 

 

Canon EOS 5Ds and 5DS R

  • Use a USB 2 ‘micro-USB’ for the 5D S and 5DS R cameras.  

 

  • Or use a USB 2 extension from your PC, and then plug your existing cable into that. The PC will treat it as a USB 2 connection.

 

If you use USB 3 to connect your Canon EOS 5DS or 5DS R to SPT Service Adjustment software, they will not communicate correctly and will probably lock into Service Mode.  This can be fixed by connecting the camera to the SPT Service Adjustment Software using a USB 2 cable.

 

 
An Overview of Data Files

Always download and save the Camera and Digital data files, first thing.  If you own the Professional or Advanced version of the software; also download and save the Calibration data files.  Each link below will take you to an expansive explanation of that data file.

 

SPT’s Canon Service Adjustment Software enables you to download and save a total of five Data Files.  

Each backup function has its own objective.

 

Camera and Digital Data Files

The Camera and Digital data files are accessible with every version of our Canon Service Adjustment Software;  Essential, Professional and Advanced.

 

Rule 1:    Always Download the Camera and Digital Data files.  

 

 

Always download and save these data files; before you do anything to the camera, even if you do nothing to the camera.  Save these data files!  Get in the habit of downloading and storing these data files for your customers.

 

 

Calibration Data Files

The Calibration Data File is accessible with both Professional and Advanced versions of our Canon Service Adjustment Software.  You can download the Calibration Data Files when you use the Main Board Replacement Plugin.

 

Rule 2:    Download the Calibration Data Files whenever possible. 

 

 

 

If you own the Professional or Advanced versions of SPT’s Canon Service Adjustment Software, use the Main Board Replacement Plugin to download and save the Calibration Data file.  Do this after you save the Camera and Digital Data files, do this even if you are not replacing the Main Board.  Get in the habit of downloading and storing this data file for your customers.

 

 

 

Auto Exposure Calibration Data Files

The Auto Exposure Calibration Data file is accessible with both Professional and Advanced versions of our Canon Service Adjustment Software.  You should download the Auto Exposure Calibration Data file if you use the Auto Exposure Calibration Plugin.

Auto Focus Shift Data Files

The Auto Focus Shift Data file is accessible with the Advanced versions of versions of our Canon Service Adjustment Software.  You should download the Auto Focus Shift Data file if you use the Auto Exposure Calibration Plugin.

 

 

When you use use the Auto Focus Calibration plugin, it opens in the Backup window.   Use the opportunity to backup the AF Shift Data file.

 
Understanding Camera and Digital Data Files

This Tech Note deals with two of the most important Data files:  Camera Data and Digital Data.  These DATA FILES SHOULD ALWAYS BE DOWNLOADED AND SAVED.

 

 

We recommend Data Backup Service using our Canon Service Software for all your customers, future customers and with every repair, service or Camera FAX.  If your have the Professional or Advanced versions of our Canon Service Adjustment Software also use the Main Board Replacement plugin to Backup (Camera) Calibration Data files.  The camera's original Data files are Gold! 

 

Camera and Digital Data Files allow you to:

  • Repair a camera using a Salvage Main Board.  After installing the salvage Main Board, upload both Camera and Digital data files from the original Main Board into the salvage Main Board …  This DOSE NOT REQUIRE INITIALIZATION! 

 

  • Install the cameras original Data files into a New replacement Main Board.  This REQUIRES INITIALIZATION using our Canon Adjustment Software Plugin ‘Main Board Replacement’.  This plugin is part of our Professional and Advanced software series.

 

  • Return the camera to its original condition.

 

Saving Camera (.cmr) and Digital (.dig) Data files will allow you to build a library which you can use if your repair requires you to replace a Completely Blown Main Board.  

 

* Data files can only be used by cameras of the same model. 

 

With a library of data files you will be able to load known good Camera (.cmr) and Digital (.dig) Data files separately (mix and match) until you find a set which is a reasonable match for the the cameras original calibration data. 

 
  • Business Promotion - having the original data files guarantees your customer that a camera can be restored to original condition.

 

 

Camera Data Files

Camera Data files contains adjustments specific for that camera, AE, AF, TTL and more.  If your camera has AF MicroAdjust, you can Save and Load your AF MicroAdjust Data files in this section of our Canon Service Adjustment Software.

 

To Download and Save Camera Data:

  • ‘Click’ Save.
  • Name the file - perhaps the camera’s serial number.  
  • Save the file you have just named.  You MUST name the file to ‘save’.  The software will add the file extension - .cmr.
  • The software will download and go through the save sequence … NOTE:  Interrupting this process can cause catastrophic failure to the Main Board. 

 

To Load the Camera Data:

  • ‘Click’ Load.
  • Find your file.
  • ‘Click’ Open.
  • The software will Load your original Camera Data.  NOTE:  Interrupting this process can cause catastrophic failure to the Main Board. 

 

  • Saving and Loading AF MicroAdjust data files follows the same procedure.  The software will add the file extension - .afm.

Digital Data Files

Digital Data files contains the Image Adjustments specific for that camera; Hot / Horizontal / Vertical Shading, Dark Value, Hot Pixels, Image CMOS and more.  

 

Saving Digital Data files is even more important then saving Camera Data files.  If the Camera Data is lost you can still use our Canon Adjustment Software to adjust the camera.  But if the Digital Data is lost our software does not offer image adjustment features.

 

To Download and Save Digital Data

  • ‘Click’ Save.
  • Name the file - usually the camera’s serial number.  
  • Save the file you have just named.  You MUST name the file or you can not do a ‘save’.  The software will add the file extension - .dig.
  • The software will download and go through the save sequence … NOTE:  Interrupting this process can cause catastrophic failure to the Main Board.

Understanding What to Do if you are replacing a completely Blown Main Board

Many repairs involve cameras that are completely dead - bricked!  When you decide that the cause is a blown Main Board you need to know the things you can do / steps you can take, to get the camera to work like a new camera.  

 

You can work the steps in order or you can vary you’re technique depending on circumstances.  However, Step 1 is always you’re preferred choice!

 

 

Step 1:    Use the Original Data Files

  1. Retrieve the data files the you saved on your PC before the camera crashed - bricked.
  2. Upload the original Calibration Data File (.cal) into the new Main Board after Initialization.
  3. Or upload the original Camera (.cmr)  and Digital data (.dig) files sepearately into a good Salvage Board.

 

 

Step 2:     Retrieve what you can

If the Main Board is able connect to our Canon Service Adjustment Software, you may still be able to retrieve some of the calibration data. The backup and restore tabs on the Main Board Replacement plugin allow you to save and load all of the calibration data at once for convenience, but you can load separate chunks of data elsewhere:

  1. Save / Load Digital data (Main window) 
  2. Save / Load Camera data (Main window) 
  3. Backup / Restore AF Shift data (Auto Focus plugin) 
  4. Backup / Restore AE data (Automatic Exposure plugin) 

As an example, it may be the case that you can save camera data but not the digital data.

 

 

Step 3:     Rescue the Eeprom

If the Main Board can NOT connect to our Canon Service Adjustment Software, you can still retrieve some data. 

 

Unfortunately, the flash ROM cannot be removed from the main board without very special soldering equipment.  But .. the Eeprom is relatively easy to desolder. It is a small 8 pin package located near the main processor, usually labelled 514E or similar. 

 

CAUTION the Eeprom is heat sensitive, overheating can corrupt its data. If you are successful you can then swap the Eeprom for the Eeprom in the replacement board

 

Note:  This procedure requires some skill, and that the Eeprom itself may be faulty - a common cause of main board failure. If the Eeprom is faulty, transferring it to the new Main Board will cause the new board to appear faulty. But on the positive side, you will have diagnosed the fault of the old board, and can get it working again by inserting a good Eeprom, saving $$$.

 

 

Step 4:     Use data from other cameras as a template

Every time you get an EOS DSLR to repair, it's a good idea to save the camera and digital data using our Canon Service Adjustment Software. As well as 'fingerprinting' the camera for future repairs on that specific camera, this will allow you to build up a library of calibration data that you can use to load into New Main Boards in different cameras / same model.  This works well more often then you would think.

 

*  If you don't have any saved data for that model, contact SPT - someone will email you known good Data Files.

 

  • If you are using a brand New Main Board, you must initialize the new Main Board first using the Main Board Replacement plugin that is part of our Professional and Advanced Canon Service Adjustment Software.  After Initialization you can upload data files. 

 

  • If you are using a known good Salvage Main Board, you can proceed with uploading your data files.

    

  • Load the Camera (.cmr) and Digital (.dig) Data Files separately from other cameras until you find a set for which the camera operates reasonably well. 
  • Check that the image looks reasonable, especially noise in dark. 
  • Check that the camera doesn't hunt too much on AF. 

 

 

Step 5:     Use SPT Advanced software to calibrate AE, AF shift, and Shutter timing

  • Once the camera is operating reasonably well, you can perform the important adjustments with SPT software. Be sure to perform AE adjustment first - This will affect the histogram for shutter timing.

Even if you only follow steps 4 and 5, you should be able to get the camera to perform as well as, if not better than, it did before the fault.

Understanding How to Evaluate Lens Sharpness

The measure of a lens is optical sharpness!  Often taken for granted with new lenses, often questioned with used lenses.  There are numerious methods to test sharpness but most are time consuming and therefore expensive.  Testing Lens Sharpness is a great service you can provide for customers.  It is also your first step in creating a Test Lens for Canon Auto Focus Calibration.  It is an easy entry into the world of Canon Auto Focus Adjustments and Canon AF MicroAdjust. 

 

SPTs Canon Service Adjustment software gives you a quick and easy way to test sharpness.  With our software you can electronically measure sharpness, display the measurement as an easy to understand graph and give your customer a screen shot of the graph (Alt + PrtSc).

 

New Lenses

Expensive lenses are better, true.  Lenses cost more because they have better glass and have tighter tolerances.  But expensive or moderate in cost, every lens is different.  In any group of lenses some are better then others.  And your customer may be perfectly satisfied with a lens of moderate price if he knows that … The lens is sharp enough.   Our Canon Adjustment Software allows you to evaluate a single lens or pick the best out of a group ... quickly.

 

 

Used Lenses

Used lenses can be a great purchase or they may have focus problems!  When you are buying a used lens you want to know which is which.  SPTs Canon Adjustment Software lets you evaluate the mechanics of a lens without disassembly... quickly.

 

 

Sharpness relies on two factors:

  • Lens Sharpness.  The combined optical quality of the lens elements.
  • Focus Consistency.  The combined tolerance of the mechanics.

Lens Sharpness and Focus Consistency are combined into a single test, done simultaneously.   You will rapidly gain experience and be to Evaluate Lenses Sharpness using our Canon Service Adjustment Software.  And as importantly you will be able to do the test quickly and present it to your customer in a easy to understand format - Screen Shots with Focus Point Graph.

 

TESTING LENS SHARPNESS

 

 

The Tools You Need to Test Lens Sharpness:

  • SPT Canon Service Adjustment Software.
  • 3D Target mounted on a 30 degrees bracket. 
  • Sturdy mount for your camera.
  • Canon EOS Camera Body - preferably your test body.

The 3D target is part of our Canon Service Adjustment Software package.  The 30 degree bracket is self made.  We recommend a professional copy stand, new or used, as your camera mount.  Your test body or your customers camera body and our Canon Service Adjustment Software - Advanced version.  

 

 

Here is the Procedure:

  • Set the camera to ‘M’ with lens wide open.
  • Put the Camera and Lens on your Camera Mount.
  • Set the lens to manual focus.
  • Align your 3D Target.
  • Set your Lens to near the closest focus for that lens. 
  • Adjust the height of your camera accordingly.
  • Manually focus on ‘0’
  • In the Software:  Use Auto Focus Calibration / Calibrate Test Lens / Start
  • Use your Focus Tool and Focus Graft to measure sharpness.
  • Shoot a Screen Shot of the active picture window for your records.

The directions might sound complicated but doing it is not.  Its like reading directions for tying your shoes .. long explanation for a simple process.

 

Some Notes

  • Setting your lens to wide open (F/Fo) and lens to its closest focus has one objective - limit the field of focus!  
  • It may take you several shots to manually focus on ‘0’ - remember Image focus is what counts NOT the focus in the viewfinder. 
  • Manually focus your lens while taking test shots until the ‘O’ in the Image is your sharpest point of focus.

Look at the three screen shot below.  The first image is a entry level kit lens, the middle image is from a good EF lens and the bottom image is from an EF L lens.  For your information the EF lens would be called ‘sharp’.

 

You can use a simple rating; soft, good or great.  You can also measure degree and depth of focus (front and back focus) in millimeters.  

 

No matter how you decide to rate a lens your customer will have a visual ‘easy to understand’ graft of their lenses sharpness.  Something that is quick to do and very easy to understand
