Datacolor SpyderLensCal Autofocus Calibration Aid

The D500 has AF adjustment which can work along with this product.

Yes, both your setups can be used with this device as long each camera has micro focus adjust.

No additional software is required.

Testing and fine tuning AF accuracy is a way to insure tac sharp images, especially important with todays high resolution optics and sensors. This feature is found in the more advanced and pro model digital cameras. Canon calls theirs AF Microadjustment and on the 5DmkII it can be accessed in Custom Function C.Fn III-8. Mentioned on page 200 of the instruction manual. The 5D mkIII is not a custom function but is under the AF menu.Both the SpyderLensCal Autofocus Calibration Aid from Datacolor & MkII Focus Calibration System from LensAlign use a detailed focusing target plus a ruler to see correct fall off. The LensAlign includes True Parallel Alignment which is the basis that provides visual verification of perfect camera positioning during AF calibration. The orientation of your camera is essential for accurate analysis and adjustment of the camera's auto-focus systems.For more information on Canons AF Microadjustment: http://bhpho.to/1g0Ighg

Yes the Datacolor SpyderLensCal Autofocus Calibration Aid is also compatible with the D800.

Yes it will , micro adjustment

Some zoom lenses and some cameras can be calibrated just fine. However, if you have a lens which requires different calibration settings at different focal lengths, and you camera only accommodates one calibration setting, then you will need to send the lens to the mfg to be calibrated before you can do the autofocus micro adjustment calibration in-camera. For instance, my old Tamron 70-200mm lens had been dropped a few times. On most of my bodies, at 70mm, I needed to adjust the MF adjustment to -5, at 135mm it needed 0 calibration, and at 200mm it needed to be +10. My old canon 7D only has one MF adjustment setting per lens. I sent the lens to Tamron, and when it came back I was able to adjust it perfectly on the 7D. However, that same lens (before sending to Tamron) could be calibrated on my 5D Mark IV. By setting the 70mm setting to -5 and the 200mm setting to +10, the calibration settings worked throughout the entire focal range.

Here are a few tips for getting the target perfectly parallel to the camera focal plane: First - Use tripods with level bubbles for both the camera and the target. If you don't have a second tripod, place the target on a table and make sure that the table is level in all directions. Second - Make sure that the center of the target and the center of the lens are at exactly the same height so that the camera is not pointing up or down relative to the target. Third - Once I think I have everything set properly, I lightly place a yard stick on the front face of the target. It is amazing how quickly you can see that the target face is not perfectly leveled. That 36 inch length amplifies any slight tilt of the target. I also place the yardstick on the target horizontally to make sure it is parallel to the camera sensor. Again, any slight left to right skewing is quite obvious.
