Hasselblad’s new XH Converter 0.8 reduces focal length, increases aperture of HC/HCD lenses on X system cameras

03 Nov

Hasselblad has announced the XH Converter 0.8, a new Speedbooster-style adapter that makes it possible to use H system lenses on Hasselblad’s mirrorless X system while reducing the focal length by 0.8x and increasing the maximum aperture of the adapted lenses by two-thirds of a stop.

The XH Converter 0.8 works similarly to other focal length reduction adapters, such as Metabones’ popular Speedbooster line of adapters. Thanks to the extra flange distance going from a mirrored body to a mirrorless body, Hasselblad is able to pack not only the adapter components inside the unit, but also five optical elements in three groups. This differentiates the XH Converter 0.8 from Hasselblad’s previously-released XH Lens Adapter, which simply keeps the focal length and apertures the same across the board with adapted lenses.

Hasselblad has created a thorough chart showing what effective aperture and focal length compatible H system lenses would be when using them with this adapter on a Hasselblad X system camera:

Hasselblad has also shared a collection of sample images captured by photographer Tom Oldham on a 907X 50C using the XH Converter 0.8 with various lenses:

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_0131422922″,”galleryId”:”0131422922″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

As tends to be the case with many adapters, not all lenses can use all of the features. The XH Converter 0.8 requires all HC/HCD lenses with firmware version 18.0.0 or later to be updated to firmware version 19.1.0 if you want autofocus compatibility, with the exception of the HC 120 and HC 120 II, which are limited to manual focus mode.

Likewise, any HC/HCD lenses that weren’t updated to firmware version 18.0.0 can’t be updated to firmware version 19.1.0 due to hardware limitations and will therefore be limited to manual focus. Hasselblad does not that since HCD lenses ‘were originally designed for a smaller format than HC lenses […] some reduction of performance in extreme corners can occur.’

Firmware version 19.1.0 for various lenses can be downloaded on Hasselblad’s website.

Hasselblad cameras must also be updated to the latest firmware, The X1D 50C must be updated to firmware version 1.25.0 or later, while the X1D II 50C, 907X 50C and 907X Special Edition models require firmware version 1.4.0 or later to work with the adapter.

The XH Converter 0.8 is made in Sweden and is available today for $ 950 on Hasselblad’s online store.

Press release:

HASSELBLAD LAUNCHES XH CONVERTER 0,8 UNLOCKING A WHOLE NEW SET OF LENSES

The XH Converter 0,8 brings new opportunities to Hasselblad photographers with the ability to unlock a whole new set of H System lens capabilities. The XH Converter 0,8, used on HC/HCD lenses attached to an X System or 907X camera, reduces the focal length of the lens by a factor of 0,8x, which delivers a wider field of view and improves the maximum aperture of the lens by two-thirds of a stop. Additionally, the XH Converter 0,8 improves lens performance in terms of contrast and apparent sharpness across the entire frame.

An impressive combination for maximizing aperture is achieved when attaching the XH Converter 0,8 to the HC f/2,2 100mm lens, transforming the aperture and focal length to f/1,8 and 80mm, respectively. This creates an extremely large aperture that proves even faster than the XCD f/1,9 80mm lens, which until now has been the highest aperture lens option for X and 907X camera systems. An example of reducing focal length with the XH Converter 0,8 is when combined with the HCD f/4,8 24mm lens, it creates an aperture of f/3,8 with a 19mm focal length. This results in an even wider lens option than the existing XCD 21 lens, the widest lens in the X System.

The XH Converter 0,8 joins a range of Hasselblad adapters and converters, including the XH Lens Adapter which allows the usage of all 12 H System lenses as they are on X and 907X camera systems. The addition of the XH Converter 0,8 to the existing accessories lineup now provides these systems with enhanced functionality for H Lenses. In addition, H System users who decide to branch into the X or 907X systems gain more versatility from their current HC/HCD Lens options.

All H System lenses with firmware 18.0.0 or later must be updated to the newest version 19.1.0 to work with the XH Converter 0,8 and to get auto focus (HC 120 and HC 120 II can only be used in manual focus mode). Other H System lenses (except HC 120 and HC 120 II) with firmware older than 18.0.0 will work but only in manual focus mode. Please note that only HC/HCD lenses with firmware 18.0.0 or later can be updated to 19.1.0. Lenses with older firmware have older hardware and therefore cannot be updated. Additionally, the X1D-50c must be updated with firmware 1.25.0 or later and the X1D II 50C, 907X 50C and 907X Special Edition cameras must all be updated with firmware 1.4.0 or later.

The XH Converter 0,8 is available now for purchase with a MSRP of €959 / £859 including VAT and $ 944 excluding sales tax. See more at www.hasselblad.com/x-system-accessories/xh-converter-0-8/.

Metabones’ new EF-RF Speed Booster reduces Canon EOS R 4K crop factor

27 Mar

Metabones has released a new Speed Booster that reduces the significant 4K video crop factor found on the Canon EOS R full-frame camera systems. With this adapter, photographers can use Canon EF full-frame lenses with the Canon RF mount, significantly reducing the 4K crop on the EOS R from 1.75x to 1.24x and the crop on the EOS RP from 1.63x to 1.15x.

As with the company’s existing Speed Boosters, it works by condensing the main lens’s field of view down into a smaller region: reducing the net focal length by 1.4x and hence lowering the F-number by one stop, compared with the adapted lens’s setting. A 50mm F2.0 combined with the adapter would become a 35mm F1.4.

The Metabones EF-RF Speed Booster ULTRA 0.71x is constructed of 5 elements in 4 groups and features an ultra-high index tantalum-based optics, magnification of 0.71x and a max output aperture of F0.9. The Speed Booster supports dual-pixel autofocus, video AF, plus it has IS lens support, a built-in Control Wheel for accessing various functions like shutter speed and ISO, an LED indicator and automatic adjustment of the autofocus speed.

As far as construction is concerned, Metabones used a rubber gasket to help protect against moisture and dust, as well as flocking to cut down on internal reflections. The Speed Booster is made from brass and aluminum alloy with chromium plating and a satin finish. The tripod head is detachable and can be used with popular ball heads from Photo Clam, Arca Swiss and Markins.

The new ULTRA model wasn’t designed for still photography, Metabones explains, but it can be used as such if the camera is in APS-C mode. Lens compatibility is fairly extensive and includes:

  • Canon EF lenses
  • Canon EF extender
  • Carl Zeiss EF lenses
  • Sigma EF lenses
  • Tamron EF lenses
  • Tokina EF lenses
  • Contax N lenses modified to Canon EF by Conurus

The Speed Booster can also be used with the Contax 645 NAM-1 adapter that has been modified for Canon EF, but it can’t be used with Canon EF-S lenses nor with APS-C lenses. Metabones stresses that those latter lenses ‘DO NOT WORK AT ALL.’

The Metabones EF-RF Speed Booster ULTRA 0.71x is available now for $ 479.

Sony reduces Pixel Shift interval to 0.5 seconds in a7R lll

10 May

Sony has released new firmware for its a7R lll camera to insert a new option for Pixel Shift Multi Shooting that reduces the delay between frames to 0.5 sec. Firmware v1.10 adds the 0.5 sec delay setting to the menu so users can halve the current shortest time between frames taken with the camera in Pixel Shift Shooting mode. Previously, delays of 1-30 seconds could be selected. The move will reduce the total amount of time the pixel shift mode takes to record the images it needs, so perhaps will also reduce the risk of movement in the subject.

Users can now also use exposure bracketing in silent mode when recording uncompressed Raw files, and the focus assist peaking display can be tuned when shooting in S-Log mode. Sony says it has improved the general stability of the camera and has fixed problems it had with Eye AF failing in when used with certain settings.

For more information, and to download firmware v1.10 for the Sony a7R lll visit the Sony website.

Manufacturer’s information

ILCE-7RM3 Camera Firmware Update

What Does This Do?
This update (version 1.10) provides the following benefits:

  • Adds the menu option to select Pixel Shift Multi Shooting (On: Shooting Interval 0.5sec)

Notes:

When using an A-mount lens via an adaptor (LA-EA1/ LA-EA2/ LA-EA3/ LA-EA4), the interval might be slightly longer

When the camera is connected to PC, please use the latest version of the Imaging Edge software

  • Adds support for bracketing during silent shooting with uncompressed RAW
  • Adds support for tuning of the peaking display level for S-Log shooting
  • Makes improvements for a condition where the Eye AF does not work with certain camera settings
  • Makes improvements for a condition where Viewfinder Brightness is not reflected correctly in the Manual setting
  • Improves overall stability of camera
