<p>[QUOTE="dougsmit, post: 4762097, member: 19463"]This is a far better response that we usually get from 'technical support' folks. The important one here is, "I encourage you to experiment and find out what works best for you!" The problem I see is that lenses are designed to cover a certain format sensor. Most lenses cover a much larger sensor when focused closely than when at distance. Most lenses are better in the middle and not as good toward the edges but some fall off faster than others. If a lens is designed to cover a certain sensor at really close distances, it is likely that it will be very unsharp and darker in the corners if focused on infinity. Many of these problems can be fixed to some extent with fancy designs using many elements or expensive rare earth glass. For what they are intended to do, it is unlikely that a manufacturer won't spend the money on design and materials. It is more likely that you will get a piece of molded plastic not even glass. Add to that, some units may be assembled better than others so two units may perform differently. There will be less difference with $1000 lenses that $10 ones. If you already own something, it makes sense to try it; if not, don't buy expecting miracles. Yesterday, I was playing taking photos with my microscope which is older than I am.
