These micro four thirds lenses by a manufacturer called Opteka are not for me. http://www.amazon.com/s/ref=nb_sb_n...eld-keywords=opteka+micro+four+thirds&x=0&y=0 But, wow, 2600mm? Also, it is nice to see third party options. I'm hoping that this is the start of a very big trend. I'd love to be able to chose from a lot of lenses.
