Lens resolution test chart suggestions?

[Vernon t]

We toss about the concept of lens sharpness all the time.

We rarely get consistent and objective in our assessments.

Facts and data can quickly destroy a perfectly good emotional rant but the empiricist scientist in me is longing for something reproducible and objective.

Before someone says "You might be a photo-geek if..."yes I already know it. My kids tell me.

Does anyone have an easily available, affordable, anyone-can-own-one suggestion for a resolution target chart.

The web search turns up the Edmond Optical charts.
Suggestions anyone????

Some are reasonable, some not.

My old reliable HP 4P does a pretty respectable job, better than I would have thought.
