AF fine tuning help appreciated.

[Energize]

So I've noticed that some lenses often focus a bit behind my subject resulting in a loss of detail, however contrast af focuses the same objects perfectly. I noticed that in the D7000 menu there is an af tuning section and setting one of my lenses to -15 results in a significant improvement in resolution at all focusing distances I've tried so far.

I've just been crudely taking photos of patterned items like wallpaper etc. to see which adjustment is sharpest, but I was wondering if there is any better way to do this?

Thanks, not so sure what the dating site has to do with photography though.

That Nikon link, looks like a lowtech version of a device made by Datacolor called the Spyder LensCal which retails for around £45

I use the Spyder LenCal, it's ok but expensive for what it is.

You might want to give this a go. It doesn't need any extra kit.

That's genius! Thanks.

It exactly matches the -15 decision I made based on comparing photographs at different corrections. So much faster than doing it that way!

I was just going to post that, well to his other thread on FM anyway!

There are some good charts that you can print off, that is what I use. Set at a 45* angle and I just use trial and error, but also test it shototing at my GF to check that my artificial etsts match natural tests.
