Very nice system. Specially for the compactness, ease of travel. I have a Nikon system, D7000, a Tamron 2.8 zoom, 50mm, filters, tripod etc. I had a 70-200mm 2.8, which i sold to buy a E-M10. Never regreted that decission. I have played a lot around with adapted lenses. Some i Had, some are Ebay buys. My experince is that it is very difficult to get usefull results. You do really have to take two or tree shots to get one in decent steady fokus. Maybe its my eyes, but its fun to play around, but never really will be a hit. It started with the GX1 with the 14-42. A lovely easy camera. Used it on some occations and vacations- I never really missed the big Nikon, especially not in transit. Never the "this photo could use the Nikon" in my mind. Almost always really nice photos. A read a lot of blogs, vlogs ect about merging to M43, before I decided to chip in the big heavy almost never used Zoom for a E-M10 and a olympus Grip. ( I have large hands ). I will never go back to the Nikon- I do still use it with a 50mm for repro or studio work. But i'm shure a result with the oly and 45 1.8 would be just as usefull. Maybe the Nikon its just an old friend thats hard to let go of, but it allmost never leave the house anymore. I used the Nikon to shoot the pic today. Gosh it felt good in the hands, but i just im tired of dragging it around. Now i'm waiting for spring and light to come back. I'm scandinavian, so January is pretty dark and grey. In the picture, GX1 with 14-42, E-M10 with adapted (mc) Tokina 300 5.6, Zuiko 200/4, Mamiya 135/2.8, Nikon 50/2+105/2.5+55-200vr, Sigma 105 macro (nikon af mount). 45 1.8 oly and Lumix 20 mmII (step up ring to fitertread 52 mm), Cheap fisheye converter 52ø. My next larger purchase would be som kind of extreme wideangle ex 7.5 mm. I really dont like the fisheye converter very much. Its big and bad. So before 2016 is over, it will go permanently in my private museum. I'm sure of that. I dont use zooms much. But i Would die for the 40-150 oly and a 1.4 converter. I love the super sharp results of a prime. Ex the Mushrooms, which by the way is cropped to about 1/3 frame. Im into Nature, street, travel, family, studio. Just misses the time. Hope this is usefull for newcomers. Sorry for the bad english, hope it makes sense.
