I currently own the Olympus 45mm 1.8 and 75mm 1.8, they are both mostly used for scenic/travel stuff and more often than not in good light. Even though it's the middle of winter here in the UK I've noticed I rarely get to utilise anywhere near wide open as the 1/4000 shutter speed limit isn't fast enough. The vast majority of my shots that I would want wide open end up around f4 or thereabouts. I know I could use ND filters, but they're a hassle. In the interests of saving a bit of money, having one less lens to change and having the bonus of 1:1 macro, would it be logical to sell both and move over to the 60mm? The 75mm is a great lens but it's a lot of money to have tied up in something that doesn't appear like it's going to get as much use as I can justify. Does anyone use the 60mm and the 45 and/or 75? I'm mainly wondering if it will be a reasonable alternative, and if the AF speed will stand up for a lot of telephoto work (mainly static subjects) as well as macro.
