p.1 #1 · p.1 #1 · Best way to af tune lenses?


I did a search here and couldn't come up with the answer I am looking for. Is there a recommended way or manner in which to fine tune your lenses to make sure they are as sharp as they can be? I have the D750 and various lenses that I can tell are just a little bit off. Any suggestions or help would be appreciated! Thanks.

Don't know if there's one best way. But I'll start with the camera on a tripod, mirror up, 3 second delay, remote release, single point AF, use live view. Find a nice target with decent contrast. Take a few shots. Make sure VR is off. Tune at the most frequently used focal length. Use the best as the benchmark. That should be your best. Eliminates human error for the comparative.

Then turn off live view and start adjusting via viewfinder until you get as close to the comparative as possible.

Many here favor Snapsy's "dot tune" method.

I'm a big fan of:

Because it is quick, fully objective, and free. And it works. An alternative to the moire pattern us just a piece of paper taped flat on the wall with some grid pattern printed to it.

I like the battery test via the tripod/mirror/live view method. Easy since most people have batteries laying around.
