    Sony FE 400mm f/2.8 GM OSS Announcement

      News

    Professional users of mirrorless Sony cameras can finally complete their arrays with a new bright FE 400mm f/2.8 GM OSS lens which has been announced for a long time.

     

    The lens has been designed having in mind sports photographers as well as the ones wanting to catch wildlife in movement – the combination of the above in the form of, for instance, a bear on a skateboard is, of course, possible.

    1). Sony FE 400mm f/2.8 GM OSS

     

    The optical system of the new Sony lens is based on 23 lenses placed in 17 groups, 3 of which are low-dispersion fluorite lenses. In order to ensure good balance of the lens, the lenses have been placed in the central and rear parts of the system. The lenses are covered with anti-reflective and fluorine coatings, which enable keeping them clean.

    The lens is equipped with a 11-blade aperture. Two newly-designed linear motors, which are supposed to facilitate the tracking of moving objects, are responsible for the functioning of the autofocus. At our disposal, we have 3 modes of image stabilization and a sharpening clutch. On the side of the lens, we have function buttons, including Full-Time DMF switch, which enables continuous manual sharpening.

    3). Sony FE 400mm f/2.8 GM OSS

     

    One of the main advantages of the lens is its construction. It has the dimensions of 158 x 359mm, it weighs only 2.7kg and it is supposed to enable, in special circumstances, photographing ”from hand”. The lens is made of magnesium and is, of course, sealed. Inserted filters with the diameter of 40.5mm can be used on the lens. In the case of using 1.4x and 2x converters, the brightness will decrease by, respectively, f/4 and f/5.6.

    4). Sony FE 400mm f/2.8 GM OSS

     

    Sony FE 400mm f/2.8 GM OSS will appear on sale in September. The enthusiasm may be cooled down by the price of the lens since, as at today, it will cost $12000.

      DESCRIPTION OF THE SONY RX100 VI
      Sony RX100 series are the most advanced compact cameras on the market. They are often used by professionals when the use of heavy professional cameras with replaceable optical system is not possible or does not make sense.

      RX100 VI is equipped with the 1'' sensor, in Exmor RS technology, with the resolution of 10.1MP. The ISO range of 125 to 12800 can be extended to ISO 80 to 25600. Thanks to the use of Bionz X processor, together with LSI chip and dedicated DRAM memory, the camera's efficiency enables taking photographs with the speed of 24f/s, or even 233 JPEG photographs in the 'Fine' quality in the buffer. The camera offers the fastest  autofocus in its class, based on 315 phase-detection points, with 65% frame coverage. The focusing time is 0.03s.

      Videos will be recorded in 4K HDR, in the resolution of 3840x2160px, with the use of the Hybryd Long Gamma profile. Full HD materials will be recorded with the speed of 120f/s, and in slow motion, the camera will be able to record even 1000 frames per second.

      The lens of Sony RX100 VI is equipped with the zoom with the equivalent of 24-200mm and it is based on 15 lenses (10 aspherical ones, including 2 low-dispersion ones), placed in 12 groups. The aperture range is f/2.8 - f/4.5, and the new processor will be able to reduce greater noise of photographs taken in low light. 

      Sony RX100 VI is equipped with a full touch LCD screen with the resolution of 1228 thousand points. The screen can be folded by 180 degrees upwards and by 90 degrees downwards. This should certainly satisfy vloggers and selfie-lovers. The camera has a retractable electronic  viewfinder with the resolution of 2359 thousand points and the flash.

      Two of the biggest telephoto Canon lenses - EF 400mm f/2.8L IS III USM and EF 600mm f/4L IS III USM have become renewed. In their third versions, the devices have significantly lost on weight, they became sealed and their ergonomy has significantly improved. 
       
      Canon EF 400mm f/2.8L IS III, with the dimensions of 163 x 343mm, lost more than one kilogram - from 3850g to 2840g. A slimming treatment of the bigger of the lenses, EF 600mm f/4L IS III USM, has been a little less successful and the lens now weights 3050g (its predecessor -  3920g) and it has the dimensions of 168 x 448mm. Both lenses have been sealed and the white finishing which characterizes the lenses from the L series is thermal insulation, thanks to which the devices are supposed to work better in extreme temperatures. In order to facilitate keeping the lenses clean, the external surfaces of the first and the last lens have been covered with the fluorine coating. 
       

      1). Canon EF 400mm f/2.8L IS III USM
       
      Both lenses are equipped with the control elements on the body enabling focus adjustment, blocking and stopping focus settings. With the use of the ring knob we can go to two pre-programmed focus positions at any time. The focus mode, focus range, programmed focus restoration and the IS controllers are placed ergonomically.
       

      2). Canon EF 400mm f/2.8L IS III USM
       
      The optical systems of both lenses are similar - in both of them we have seventeen lenses placed in thirteen groups, a 9-blade aperture which can be closed up to f/32, while the nominal aperture for 400 mm is f/2.8 and for 600mm - f/4. In both lenses we will find the elements of fluorite lenses and the SubWavelenght Structure Coating (SWC) so we can expect significant reduction in chromatic aberration, flares and blurring while maintaining high quality of the reproduced colors, high resolution and contrast. 
       

      3). Canon EF 600mm f/4L IS III USM
       
      The autofocus has also been treated as priority. New Canon lenses are equipped with ring USM motors with autofocus and an effective processor enabling fast and quiet AF work. Both lenses make it possible to obtain the  "pull-focus" effect with focus regulation and focus preset. Manual focus adjustment in full-time is also available and the focusing speed can be adjusted also by manual electronic regulation. 
       

      4). Canon EF 600mm f/4L IS III USM
       
      The lenses are to appear on sale in December and they will cost respectively:
      Canon EF 400 mm f/2.8L IS III USM - $12,000
      Canon EF 600 mm f/4L IS III USM - $13,000
       
      In the sets we will find only soft cases. Hard suitcases and new short hoods will be available optionally.
