I want to play around with some single spherical lenses of different types - meniscus, dcx, pcx, diameters and focal lengths, but want to make sure they will cover the sensor without too much vignetting before I buy.

What is the simplest approach to this?

You will probably get more advice at Adapted Lens Talk
Thee first question will be what mount and sensor size are you talking about.

Thank you, Bill.  I am hoping to learn the (barest of the) underlying theory, so that I can develop a better intuition about this.
