Since most of you guys shoot video professionally, i'd like to get your opinion when it comes to testing camera lenses. What is the preferred method of testing: shooting video and extracting one frame, or utilizing the camera's photo mode (if available) and shooting a still photo image? Or does it not matter which method is used?
I'll have to peruse the B&H site. I'm sure they sell simple charts I can buy to undertake my simple lens tests.
If you're talking about the lens on a video camera, the tried and true method is to use a proper test chart. B&H does sell a lot of different ones. The chart manufacturer that I'm familiar with is DSC labs and here's a link to their resolution charts. http://dsclabs.com/resolution.htm
If those are too much money for you, here's a link to a free one that you can download and print. This one is designed for still cameras but might be suitable for your use. I highly recommend using a laser printer for the best possible quality. http://www.graphics.cornell.edu/~westin/misc/res-chart.html
Google "video lens test chart" (without the quotes) as there are a lot of sites out there with very useful information.
