The 12-40 is billed as being at the top end of the lens lineup. Unlike the previous high grade primes (12/2, 17/1.8, 75/1.8, click on the links for my reviews), the 12-40 is ‘triple proof’ – fully environmentally sealed to match the E-M1, and dust-, splash- and freeze-proof. It has a very nicely made machined aluminium barrel and zoom/ focusing rings, all of which are textured and grippy for use with gloves; overall finishing quality is on par with the primes; unfortunately all of this metal and robustness comes at a price – 382g of weight and bulk (70x84mm, 62mm filter). The lens is larger and heavier than the Panasonic 12-35/2.8, and slightly larger than the 75/1.8 (without hood). The lens also adds a programmable L-FN button for use with your thumb when cradling the combination with your left hand. At the asking price – I’m told in the region of US$1,000 – Olympus have finally included a hood and center-pinch lens cap; both of which are high quality items. The hood is reversible for storage, has a bayonet lock and metal rim; the lens cap appears to be mostly metal and rather nice looking, though I suspect also easily dented.
