The Fuji 50 - 140 is a behemoth of a lens, gigantic, heavy and pricey. But it is weather sealed, has OIS and a constant aperture of f/2.8 so is it worth spending the money? I take it to the beach at Hunstanton to find out.
I reviewed the Nissin i40A a few months ago and I really liked it. I reviewed the Nissin i60A a couple of months after that, and I liked it even more. But there is another wireless TTL flash for Fuji cameras to consider from Nissin; the Di700A.
