>>4155529>It’s smaller and has more reach cry moarThe Olympus 40-150 f/2.8 cannot be compared to the Sony 70-200 f2.8, you need to compare it to a Sony 80-300 f5.6.
Sony does not make a 80-300 f/5.6, but they do make a 70-300 f/4.5-5.6, which is *15mm shorter* than your M43 lens and has a brighter equivalent aperture at the short end of the zoom range and a wider zoom range on top of that.
