There are four test chart snap-shots from four different lenses shown on the left.
For obvious reasons there are no lens manufacturer's names mentioned.
All lenses are claimed to be mega-pixel lenses.
The same camera is used throughout and all camera settings are identical. The angle of view, compression settings and illumination are also identical.
All lenses are focused for best possible image.
Even though the exported images are reduced and cropped (for the purposes of displaying on the web site) the image quality is obviously different, the top one being the best, and lowest being the worst.
All lenses are vari-focal, mega-pixel and within a similar price range.
Lens quality may be one of the most important factors in obtaining the best possible image for your cameras.
The ViDi Labs test chart is one of the easiest and optimal methods for objective comparison and testing.

|Using the ViDi Labs SD/HD test
chart it is possible to test and measure the effect of fast moving
objects on the resulting recorded video.
With this new and unique method we have advised this process, and offered some formulas that will help in determining such pixel shifting, while taking into account all the possible variables.
We used the same formula to calculate pixel blurriness due to moving objects in the ViDiLabs Calc.
The test example on the left illustrates the appearance of movement (in this case oscillating test chart) and shows the accuracy of the developed formula above.
