I recently bought into the M43 system, with an Oly ELP5 and Panny GF3, along with the Zuiko kit lens, Panny 14mm and Sigma 19mm. I also have a couple legacy lenses with adapters which I've come to enjoy very much, though I'd like to round up my collection with a native portrait lens and 45-150mm zoom. The 45mm Zuiko would be the obvious choice, but I've come to be very puzzled with Olympus concerning their concept of build quality. The silver EPL5 body feels great in the hands until you have to handle the abominable scroll wheel and mushy Fn/Loupe buttons (why are these even plastic?? The rest of the controls are metallic and much better quality!). The 14-42mm also feels so cheap, cheaper than any other lens I've ever handled or seen, and while I love the form factor, It's disappointing to handle it at all, though I can put up with using it because it performs much better than it looks. Then, I'm worried when I look at the 45mm in pictures and I fear it will be more of the same cheap-looking mushy plastic as the other two?? Even though I don't doubt it's optically great, if the build quality is this bad I'd like to look at other options. Namely I'm thinking of the Sigma 60mm or an M-mount 40mm Voigtlander. These options all have their disadvantages. I'd like some reassurance about the 45mm Zuiko's build quality before deciding, or some advice on an alternative otherwise.
