Just wondering if any of you guys do a calibration check of your new cameras to see if they are spot on or not. I used my 24-70 2.8 lens on all four of my Canon bodies to check them for pinpoint accuracy. Out of all of them only the 6D MK 11 was just a smidgeon off.

If you mean the AF accuracy for DSLRs, I calibrate the camera’s MFA to each lens using Riekan’s FoCal calibration system.
Each lens has different tolerances, so the calibration for each lens is different, which the camera “remembers” and implements when that lens is mounted. Your 6D2 supports Microfocus adjustment and provides 1 value for each prime and 2 values for each zoom for at least 20 different lenses.

You may not realize it, but you may have just rekindled the age old UHH debate about calibration and whether it’s necessary and who should do it if so - you or the camera and lens factory service center. Stand back - it can get heated!

As an old time film shooter, who used to use the "sunny 16" rule until I got a Gossen meter, camera calibration is much less important to me than how the images turn out.

Let me see . . . . You want to know if I second guess a highly sophisticated and expensive piece of electronic gear engineered for the highest levels of accuracy ever attempted by man and micro adjusted by a computer? The same piece of gear which gives me beautiful exposures under the most dreadful conditions and exposures second only to what the human eye can decipher.

Nah, taking pics and "polishing" them software is what makes me . . . .

With mirrorless lens calibration is a thing of the past.
BUT, IMHO, even with my film and digital mirrored camera's I NEVER had to calibrate a lens. Lens calibration often results in increasing the lens issues. Many author's of camera's caution against calibration.
Good luck and keep on shooting until the end.

Modern cameras are very well calibrated at the factory. If you think that your camera needs calibration Canon is your best friend.

DSLR camera bodies are made in 1 physical location & lenses are made in another...Vendors use an established set of values installed on each. Due to the sensor being installed by a machine, during building, the fine tuning may or may not need to be needed.

No, I just use them.

NO. Mirrorless Cameras do not get out of focus calibration, because focus is achieved on/at/by the sensor. dSLRs and SLRs require calibration because focus is achieved separately at the film plane from the ground glass. But I quit using them many years ago.

If you mean EXPOSURE calibration, yes, I always check that, regardless of the technology. It is seldom off by more than 1/3 stop, for which I use a simple exposure compensation. White balance can require a hue offset adjustment, but that is rare. It's mostly irrelevant to raw workflow.

Gotta blame it on something.

If that were sufficient, then the Auto AF Fine-tune values would have been stable, and not have had to be periodically corrected on my D500 for the 200-500mm. Every few months, especially with temperature/humidity change.

Haha! Absolutely! 🤔😏😎
