Hands-on with Phase One 45mm F3. 5 and 150mm F2. 8 Phase One is showing off two new 'Blue Ring' lenses at this year's Photokina tradeshow in Cologne, Germany. We visited the Phase One booth earlier and got our hands on them.
First up is the new 150mm LS F2. 8 IF, which offers a focal length equivalent to 64mm on full-frame, making it a useful portrait prime. At first glance this is an enormous lens, but a lot of its apparent size is actually the detachable hood.

F2. 8 is fast for a medium-format lens, which should ensure nice shallow depth of field when used wide-open for portraits. Here's a view straight down the front of the lens. See what we mean about that big hood?

With the hood removed, the 150mm becomes a good deal smaller. The new lens can synchronize with flash at shutter speeds of up to 1/1000sec and can focus as close as 100cm/3. 2ft. It uses 8 elements in 7 groups and accepts 105mm screw-in filters. It could be yours for only $6990/€5990.

Next up is the 45mm LS F3. 5, which Phase One tells us will offer extremely good edge-to-edge sharpness, even wide-open. Aimed at landscape photographers, the 45mm (and indeed the 150mm) offers a simple auto/manual focus clutch switch. Shifting to manual focus is as easy as pulling the focus ring towards the camera.

Like the 150mm, the 45mm features a leaf shutter inside the lens itself, and it can synchronize with flash at shutter speeds of up to 1/1600sec. Construction comprises 10 elements in 7 groups.

Equivalent to a 28mm field of view on full-frame, the new 45mm F3. 5 has a closest focusing distance of 55cm/1. 8ft. It is available now for $5990/€5290.

This is Lau Norgaard, VP of R&D at Phase One. He's pretty pleased with his new lenses - what do you think? Let us know in the comments.
