[Updated] Phase One Announces First Schneider Kreuznach Blue Ring Zoom Lenses

In partnership with Schneider Kreuznach, Phase One has added two Blue Ring zoom lenses to their impressive lineup of high-end imaging products. These new full-frame 645 lenses, the 40-80mm LS f/4.0-5.6 and 75-150mm LS f/4.0-5.6, promise prime lens quality with improved precision and advanced electronics. Phase One will be hosting a webinar on July 19 where you can watch a hands-on demonstration of these lenses.

Update: Check below for sample images from these two lenses.

When paired up, the two new Blue Ring zoom lenses offer a 40mm-150mm zoom range covering wide to normal to telephoto. Both the 40-80mm LS and 75-150mm LS lenses have a zoom lock function and are designed to maintain focus position while zooming. These leaf-shutter lenses support flash synchronization up to 1/1,600 s.

With front lens diameters of 63mm an 65mm, Phase One Senior Product Manager Espen Beck said in the press release, “Creating optics this large with such tight tolerances is quite an achievement.” He continued by explaining how capturing full resolution images with a square 100-megapixel medium-format sensor using a round lens requires a larger overall lens, which needs larger lens elements and larger movements, all while maintaining speed and precision.

“Schneider Kreuznach lenses are designed to deliver the ultimate analog input to be shaped and refined with the Phase One XF 100MP Camera System and Capture One software. This design also benefits the Phase One XF 50MP system, which can exploit the ‘sweet spot’ of the lens, producing impeccable results,” said Beck.

"are designed to maintain focus position while zooming"

Does this mean these lenses are parfocal or does this mean something else?

Sounds like parfocal to me.

Well, I wasn't sure if this could mean some sort of internal choreography between the focus ring and the zoom ring. It's possible to keep focus on a non-parfocal zoom by adjusting/syncing the focus AS you zoom.

This was rumored sometime ago at P1 Rumors:
As an owner and user of blue ring design 120mm f/4 SK LS macro lens, I'd say that focal plane 120mm AF macro was performing better in terms of sharpness and resolving power (even not counting size, weight and autofocus speed because of obvious reason - BRD is a leaf shutter version of the original macro lens). There is a quite good P1 120mm lens comparison done by Capture Integration which you might be interested at:
Now I need to wait and see the performance of blue ring design 40-80 zoom lens, which I'd like to invest in :)
