Re: Interesting article
If you're doing landscapes, the only advantage a bigger sensor/camera will get you is resolution. And nobody really cares a whole lot about resolution anymore because the platforms we view pictures on are actually really small these days.
If you're doing travel, m4/3 cannot be beat.
But if you need shallow depth of field at wider focal lengths, such as full frame 35mm equiv., which you would for most wedding work for example, m4/3 is not for you. If you look at pictures taken with a FF and a 35mm f/1.4 or 50mm f/1.4 or 24mm f/1.4, you simply cannot get that look with m4/3. The question is, do you want to? Do you need to? Are you willing to spend thousands of dollars more for your equipment?
