I want to test lens sharpness

[reyhan]

I need a chart for this and I don't know how to find a suitable chart. Also, what paper should I choose when printing from a scanner? Has anyone printed a chart at home to test the sharpness of their lens? Can you help me with this?

I use a product called Spyder LENSCAL I recommend. with is you can easily check front/back focus. just have camera and target on same level. below not so but for demo only UK price around £45. Just focus on the small square

Thank you so much

That's for focus accuracy. For sharpness, you'll need a resolution test chart. They can be found on line by searching for those words.

It is acceptable to remove a page from a magazine, place it on a flat wall and photo it. Check the sharpness of the text, so on.
