Zoom Lens Image resolution Testing Calculations

A contact lens fills the gap concerning the camera and the article. The magnification of typically the lens doesn't mean more effective quality photos, but you possibly can determine the quality that lens brings by trying out its resolution.

Testing a lens requires specific glasses test charts, preferably for a white background, and any tripod. You need to understand the measurements of your current test board area, and the magnification value used once photographing the charts.

Viewing the particular photos at 100 % with image editor software means that you can analyze the performance on the lens, to see how nicely it detected the faintest lines to the chart. The black and white lines -- that will be distinguishable from the other person -- determine the side to side and vertical directions. The numbers indicate your lines per millimeter the fact that lens detected.

Multiplying this horizontal lines per millimeter value from the magnification used reveals your resolution for that lens. The calculation can be repeated for vertical.

For ideal results, you need to check the lens at numerous apertures and distances. A lot more tests conducted, the more accuracy and expertise in the lens gained. Image resolution isn't according to one factor, but rather combining the lens and the particular camera sensor. Testing for both comes with better resolution.
