So i just had a bit of GAS over the last week. I now have: - Olympus 14-42 with epl1 - Olympus 14-42 with epl2 - Olympus 17mm f2.8 - Olympus 20mm f1.7 - Olympus 45mm f1.8 - Olympus 40-150mm - Panasonic 45-200mm I want to make my collection a littler smaller, but im not too sure what to get rid of. The main things i shoot are: Cars Nature Social events Concerts Lots of low light things I havent had much experience with alot of the lenses since i just purchased most of them over the last week. The most experience i have is with the epl1 kit lens and 17mm which i used for over a year. Please let me know which lenses are best for each application. You can also suggest a lense i dont have as well as im happy to acquire new stuff.
