ORIGINAL POST
PLEASE SHARE YOUR SONY 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots.
Interestingly, with 87 lenses reported, not a single bad one with serial number below 10,000. Over 10,000, 42% of the lenses seem to exhibit the focus shift.

PLEASE SHARE YOUR SONY 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots.
Interestingly, with 87 lenses reported, not a single bad one with serial number below 10,000. Over 10,000, 42% of the lenses seem to exhibit the focus shift.

PLEASE SHARE YOUR SONY 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots.
NOTE: If you have access to the box, please check the serial number suffix (i.e. 'A', 'D', etc) and share that as well. See photo for location.
I will update this post, as new submissions come in.

24-105mm FOCUS SHIFT survey - submit serial numbers
Pulled this out from the main 24-105mm thread.
PLEASE SHARE YOUR SONY 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots.
NOTE: If you have access to the box, please check the serial number suffix (i.e. 'A', 'D', etc) and share that as well. See photo for location.
I will update this post, as new submissions come in.
________________________
Here's the list, with all submissions so far -
Interestingly, with over 80 lenses reported now, not a single bad one with serial number below 10,000. Over 10,000, 45% of the lenses seem to exhibit the focus shift.

24-105mm FOCUS SHIFT survey - submit serial numbers
Pulled this out from the main 24-105mm thread.
PLEASE SHARE YOUR SONY 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots.
NOTE: If you have access to the box, please check the serial number suffix (i.e. 'A', 'D', etc) and share that as well. See photo for location.
I will update this post, as new submissions come in.
________________________
Here's the list, with all submissions so far -
Interestingly, with 81 lenses reported now, not a single bad one with serial number below 10,000. Over 10,000, 45% of the lenses seem to exhibit the focus shift.

24-105mm FOCUS SHIFT survey - submit serial numbers
Pulled this out from the main 24-105mm thread.
PLEASE SHARE YOUR SONY 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots.
NOTE: If you have access to the box, please check the serial number suffix (i.e. 'A', 'D', etc) and share that as well. See photo for location.
I will update this post, as new submissions come in.
________________________
Here's the list, with all submissions so far -
Interestingly, with 80 lenses reported now, not a single bad one with serial number below 10,000. Over 10,000, 46% of the lenses seem to exhibit the focus shift.

24-105mm FOCUS SHIFT survey - submit serial numbers
Pulled this out from the main 24-105mm thread.
PLEASE SHARE YOUR SONY 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots.
NOTE: If you have access to the box, please check the serial number suffix (i.e. 'A', 'D', etc) and share that as well. See photo for location.
I will update this post, as new submissions come in.

NOTE: If you have access to the box, please check the serial number suffix (i.e. 'A', 'D', etc) and share that as well. See photo for location.

24-105mm FOCUS SHIFT survey - submit serial numbers
Pulled this out from the main 24-105mm thread.
PLEASE SHARE YOUR SONY 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots.
NOTE: If you have access to the box, please check the serial number suffix (i.e. 'A', 'D', etc) and share that as well. See photo for location.
I will update this post, as new submissions come in.

24-105mm FOCUS SHIFT survey - submit serial numbers
Pulled this out from the main 24-105mm thread.
PLEASE SHARE YOUR Sony 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots. Here's an example of how it looks - https://www.fredmiranda.com/forum/topic/1517297/36#14349657
I will update this post, as new submissions come in.

Here's the list, with all submissions so far -
Interestingly, with over 60 lenses reported now, not a single bad one with serial number below 10,000. Over 10,000, about half of the lenses seem to exhibit the focus shift.

24-105mm FOCUS SHIFT survey - submit serial numbers
Pulled this out from the main 24-105mm thread.
PLEASE SHARE YOUR Sony 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots. Here's an example of how it looks - https://www.fredmiranda.com/forum/topic/1517297/36#14349657
I will update this post, as new submissions come in.

Here's the list, with all submissions so far -
Interestingly, with 60 lenses reported now, not a single bad one with serial number below 10,000. Over 10,000, about half of the lenses seem to exhibit the focus shift.

24-105mm FOCUS SHIFT survey - submit serial numbers
Pulled this out from the main 24-105mm thread.
PLEASE SHARE YOUR Sony 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots. Here's an example of how it looks - https://www.fredmiranda.com/forum/topic/1517297/36#14349657
I will update this post, as new submissions come in.
________________________
Here's the list, with all submissions so far -
Interestingly, with over 50 lenses reported now, not a single bad one with serial number below 10,000. Over 10,000, about half of the lenses seem to exhibit the focus shift.

24-105mm FOCUS SHIFT survey - submit serial numbers
Pulled this out from the main 24-105mm thread.
PLEASE SHARE YOUR 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots. Here's an example of how it looks - https://www.fredmiranda.com/forum/topic/1517297/36#14349657
I will update the list in this first post, as new submissions come in.
________________________
Here's the list, with all submissions so far -
Interestingly, with over 50 lenses reported now, not a single bad one with serial number below 10,000. Over 10,000, about half of the lenses seem to exhibit the focus shift.

24-105mm FOCUS SHIFT survey - submit serial numbers
Pulled this out from the main 24-105mm thread.
PLEASE SHARE YOUR 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots. Here's an example of how it looks - https://www.fredmiranda.com/forum/topic/1517297/36#14349657
I will update the list in this first post, as new submissions come in.

Here's the list, with all submissions so far -
Interestingly, no bad ones below serial number 10,000. That sure sounds like it could be batch one and batch two to me.

24-105mm FOCUS SHIFT survey - submit serial numbers
Pulled this out from the main 24-105mm thread.
PLEASE SHARE YOUR 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots. Here's an example of how it looks - https://www.fredmiranda.com/forum/topic/1517297/36#14349657
I will update the list in this first post, as new submissions come in.

24-105mm FOCUS SHIFT survey - submit serial numbers
Pulled this out from the main 24-105mm thread.
PLEASE SHARE YOUR 24-105mm 4 SERIAL NUMBER AND WHETHER OR NOT YOU'VE HAD THE FOCUS SHIFT PROBLEM.
The easiest way to test for this is on a tripod. Zoom to 105mm, manual focus, set to 4. Focus using the magnifier and take a shot. Then without changing anything else, stop down to 8 and take another shot. Compare the shots.
I will update the list in this first post, as new submissions come in.

Here's the list, with all submissions so far -
Interestingly, no bad ones below serial number 10,000. That sure sounds like it could be batch one and batch two to me.
