In his article in AP 26th September issue Rob Cottle wax's lyrical about the advantages of the Olympus OM-D E-M1 over the bulk of the Canon 7D mk ll. Coupled with the 300 mm lens it definitely has a weight advantage over the Canonl but the 300 mm is the longest lens that Zuiko make and in the photograph on page 50 it is just as bulky looking as the Canon 100-400mm so I wonder how the equivalent Zuico would compare if it was available. He also ignores price with the Olympus kit shown being £1000 more expensive than the Canon. No doubt a Zuiko 400mm lens would be even more expensive. The article is not a fair comparison!
