Hi Guys, My current camera is an E-PL6 + Sigma 30mm f2.8. Now here's my dilemma. I'm planning to get the Sigma 60mm f2.8 and here in Singapore, it costs $270. Now Olympus a cash back promotion and the Olympus 45mm is now priced at ONLY $299. Knowing that I already have the 30mm and is wanting a semi-portrait lens, should I go with the Sigma 60mm or the Oly 45mm? Is the Oly 45mm too close to the 30mm I currently have? I was in favor of the Sigma because of the price difference between the Olympus before the promotion. But now that they're closely priced, I'm having a hard time deciding. Your opinions are highly appreciated.
