Hi folks, A few month a go I bought an E-PM1 with the kit lens and now want to improve it with a second lens as a portrait lens. I've two options: 1. Olympus 45mm 1.8 for $399 2. Olympus 40-150mm for $179 To be honest I don't no wich one will work for me. In fact I've heard that 45mm is a magic lens for portrait, But the difference is $220 and I don't know if I really need 1.8 and should go for 45mm (since I'm not a professional photographer) or 40-150mm would give me an acceptable result at 40mm and I should get that one, save money and spend it on something else (like a flash or...etc). At the end I need to mention I don't need a telephoto lens and I'm considering 40-150 as a 40mm lens (I feel at 40 it's much better than the kit lens. Isn't it?) I'll appreciate if you guys kindly give me some advise.
