I bought a Lumix G5 for a great price and I'm loving it (great perf, best bang for the buck for a camera w/ EVF). However I'm not blown away by the stock 14-42 Vario PZD and looking to buy some new lens (Especially a short prime for low-light and street) Also, my friend who lured me into m43 told me the lens from m43 are way cheaper. And that come from someone who own must of them. However, I'm comparing the prime I want with their Nikon APS-C equivalent, and they are 2-3 time more expensive. However, it's true that zoom lens tend to be cheaper, however, for some common telephoto the difference is not much. For exemple. Nikon 35mm f/1.8G AF-S DX -> 200$ new, 50mm equiv Olympus 25mm f/1.8 -> 500$, 50 equiv Nikon Nikon 55-200mm VR AF-S f/4-5.6G -> 250$, easily found for 200$, 82-300mm equiv Olympus M.Zuiko Digital ED 40-150mm f/4.0-5.6 R Lens -> 200$, 80-300mm equiv So m43 being smaller, shouldn't they those lens be less costly to produce? Especially prime lens, that are more simple construction? Can we say that m43 lens are generally cheaper? If not which are more expensive and what other are cheaper? I love the m43 format, but I find the lens I want and need cost more than on APS-C DSLR, I might want to switch. Since my goal is to make great picture on a budget.
