The Vello LENS-2020 Lens Calibration Tool sets up quickly onto a tripod through its 1/4"-20 tripod mounting socket and can level out using the two-way bubble level at the base of the target. With this tool, you can test your camera's auto focus accuracy and then calibrate the focus system to correct for any front-or back-focusing issues. After the adjustment is saved within the camera as a lens profile, it can be used for future photo sessions. The included gray card helps you to set custom white balance for true colors, and the target folds flat for easy storage and portability.

Vello LENS-2020 Reviews
Well made, Works
To get the readings you see in the adds you need to use an incredibly low F-stop setting. But after a quick session with several lenses I am convinced my camera was focusing well with all the lenses. It's nice to know that any Pics out of focus are my fault not the camera's
Overall Good
This calibration tool works as it is supposed to. I like that it can be attached to a tripod. The overall layout is simple and straight forward. The issue is setting it up. It doesn't slide out intuitively, and the locking mechanism behind the ruler is difficult to engage. I'll worried that it will break as I force it.
Not much to say
It is what it is
As expected
What else is there to say. It is what it is
Still learning to use it.
Seems good. Learning to use it.

Target with ruler and tri-pod mount is great
Pros: + The target in combination with the ruler is great. + Having the 1/4 tripod mount is very useful to hold it steady during usage which is very critical. + Comes with a bag to keep it clean and protected. + The hinges are two part cupped not single piece flexi type that break off. Cons: - The grey card falls right out holder as there is only a very small lip at the bottom and nothing to hold the card in slot. Have to put the unit in upside down so the card does not fall out of the bag also. - In order to latch close the unit, you have to squish between the face, which is right over the ruler and the back of the unit. The problem is you don't want to be touching the ruler and getting it dirty. Neutral: Have no use of the bubble levels as even if you make it level in both directions, and your camera is perfectly level, that is no guarantee that with the target in the center of the image that the target and camera are perfectly squared up (needs to be with in 0.5mm if you want the ruler measurements to mean anything.
Inexpensive way to test your lenses.
A bit flimsy but it works just fine for an occasional lens test. Plus it comes with a nice size plastic Gray Card for setting your White Balance.
