your camera, the better the results will be, but in any case if you look
carefully at shots taken even by the most expensive cameras equipped with the
most expensive lenses you will see various artifacts.  It is very hard to make
ideal cameras, because there are a lot of factors that affect the final image
quality, and at some point camera and lens designers have to trade one factor
for another to achieve the optimal image quality, within the given design
restrictions and budget.  But we all want ideal shots, don't we?  So that's
what's Lensfun is all about: rectifying the defects introduced by your
photographic equipment.")
