I have been reading about lens calibration and have watched a video of the technique. I have not yet tried calibration yet. My question is is I calibrate my principal lens, a Tamron SP 24-70 mm F2.8 Di VC USD G2, on my camera, Canon 5D IV, if I change to another lens, such as a Tamron SP 70-200 mm F2.8 Di VC USD G2, will that lens be affected by the camera calibration of the first lens? Does the camera hold in its memory calibration data for each lens?

YES.

My Nikon DSLRs allow me to save adjustments for each lens and allows me to number/define them. I don't remember if it automatically adjusts when you change lenses. I believe however that for example, an adjustment made for a 50mm F1.4 lens does not impact an adjustment for another lens so long as the camera knows the lens.

I can also add a question for this topic if you don't mind.
I have a Z6 mirrorless and cannot get my Spider Pro 5 to work its software for a fine tune adjustment. Do I need to update the Spider?

Calibrating a lens will only be for that lens, the camera will hold individual calibrations for all your lenses. Mirrorless cameras by virtue of they way they work do not require lens calibration.

Canon can store the calibration data by the serial number of the lens, so even if you use multiple copies of the same lens, the camera can tell the difference. The details regarding how / if the camera can detect the 10-digit serial number are covered in your EOS 5DIV User Manual in the section starting on page 152.

I have calibrated several Tamron lenses including the 24-70mm f/2.8 G2. I did not change any settings in my camera at all. I hooked Tamron's USB dock up to the lens and found the tuning table has 12 entries. The distances are 1.25', 3' and infinity and the zoom factors are 24mm, 35mm, 50mm, 70mm. I tested for front and back focus at all 12 entries and made appropriate adjustments using the USB dock. It is a great lens that gets glowing reviews. I hope you enjoy it.

Thanks for the feedback. I violated one of my own principles: Have a question? See if its in the manual. Page 152 of the 5DIV does begin a lengthy explanation of lens calibration and the camera can store the info for up to 40 lenses. I will give it a try. Might be back with some added questions on this topic after I do it.

I wonder which is the better calibration method? Using the Tamron attachment or the camera software? Using the camera software certainly does not incur buying the attachment from Tamron. If I do not get the results from the calibration via the camera, I will try the lens attachment method. Thanks for the feedback

The advantage of the dock is the number of calibration points (12), while your 5D4 will store 2, at whatever focal lengths you choose.

The USB Dock allows you to tune the lens at more points, allows you to update firmware and you can do some AF customization. They are not that expensive. I am invested in Nikon and found that Nikon zooms tend to hold focus throughout the zoom range. So, if you calibrate at, say, the far end, it will be in tune at the close end, so I use the AF fine tune in my bodies. This is not the case with Tamron glass. My tuning tables are all over the map, but once tuned, they perform well and I have moved them from one body to another without having to retune. The fact that Tamron glass does not hold focus throughout the zoom range is probably why they are not as expensive as equivalent Nikon glass, but like I said, once tuned, they perform very well. I can’t speak to Canon dslrs and glass as my last Canon camera was an AE-1.

This is for a Canon NOT Nikon.
