Both lenses in stock as this was written.
Also new and in stock: Fujifilm X-T10.
Sony FE 90mm f/2.8
This lens arrived for review a week ago, but with no Sony camera body, I sent it back—I’ve elected to defer review to the new Sony A7R II until late July when the A7R II is expected to ship (I expect to have one of the first shipment available).
I never did buy a Sony mirrorless body—too many flaws—but I will be buying the A7R II for sure, since the A7R II addresses most of the flaws of the Sony A7R and as a bonus has upped the resolution.
Canon EF 100-400mm f/4-5.6L II IS
I reviewed the Canon EF 100-400mm f/4.5-5.6L IS II a few months ago on the Canon 5D Mark III. It has many fine properties, and is a serious upgrade over its predecessor. It will show some weaknesses on the new Canon 5DS R, but that’s the case with all Canon EF lenses.
