Hi guys, I am planning to buy an Industar-69 28 mm f/ 2.8 and Industar-50 lenses for Olympus EPL5 - so then I need just any m39 to m4/3 adapter from these ones? and they will fit without any issues? http://www.ebay.com/sch/i.html?_sac...&_nkw=m39+to+m4/3&LH_PrefLoc=2&rt=nc&LH_BIN=1 if so, which one cheapest and smallest you can recommend? - there is a two 50mm lenses: Industar-50-2 50 mm f/ 3.5 Lens and Industar-50 50 mm f/ 3.5 http://allphotolenses.com/lenses/item/c_551.html http://allphotolenses.com/lenses/item/c_2183.html what do you think which one is better? thanks!
