Tamron 70-300mm F4.5-6.3 Di III RXD (Sony FE Mount)

The Tamron 70-300mm  F/4.5-6.3  Di  III  RXD  (Model  A047)  for  Sony  full-frame  E-mount  mirrorless  cameras  is  a  telephoto  zoom  lens  designed  and  created  so  photographers  of  all  skill  levels  can  enjoy  high  quality  images  comfortably.  It  achieves  the  world's  smallest  size  and  lightest  weight,  coming  in  at  148mm  (5.8  in)  long  with  a  maximum  diameter  of  77mm,  and  weighing  just  545g  (19.2  oz).  With  special  emphasis  on  resolving  power, Tamron has deployed special lens elements appropriately arranged to correct chromatic aberration, generally very strong in a telephoto lens, as  well  as  other  aberrations.  Users  can  enjoy  high-resolution  images  combined with the stunning bokeh qualities that are achievable only with a  telephoto  lens.  The  lens  also  incorporates  the  RXD  (Rapid  eXtra-silent  stepping  Drive)  stepping  motor  unit,  a  high-speed  precision  AF  drive  system that is remarkably quiet. The 70-300mm F4.5-6.3 is a versatile lens for  photographing  landscapes,  sports  and  other  action,  pets  and  wildlife  and  more.  The  lens  also  demonstrates  its  potential  for  portrait  shooting,  casual  snapshots  and  scenarios  that  require  you  to  be  mobile  and  shoot  handheld,  like  sporting  events.  The  apparent  image  compression  and  the  close-up  effects  characteristic  of  telephoto  lenses  naturally  amplify  photographic expression. Zooming in on distant objects and making them appear  closer  is  one  of  the  joys  of  telephoto  shooting.  This  zoom  lens  provides an entryway into that new world.

High quality images with beautiful, dreamy bokeh

Superb AF keeps it sharp and quietThe lens is made up of15 elements in 10 groupswith  an  appropriate  arrangement  of  LD  (Low  Dispersion)  lens  elements.  Aberrations  such as axial chromatic aberration (which tends to  occur  in  telephoto  lens  designs)  have  been  well  corrected.  The 300mm end, which receives  particularly  frequent  use  in  a  telephoto  zoom,  provides  excellent high-resolution performance from the center of the image all the way to the corners. Stunning bokeh (intentional background blur qualities) are another remarkable feature of this new lens.

Superb AF keeps it sharp and quiet

The AF drive incorporates an RXD (Rapid eXtra-silent stepping Drive) stepping  motor  unit.  RXD  uses  an  actuator  that  is  able  to  precisely  control  the  rotational  angle  of  the  motor,  allowing  it  to  drive  the  focusing lens without passing through a reduction gear.The  addition  of  a  sensor  that  detects  the  position  of  the  lens  to  a  high  degree  of  accuracy  enables  high-speed  and  precise AF, which allows you tomaintain razor-sharp focus when shooting  continually  moving subjects  or  filming  video.  The  lens  is  also  remarkably  quiet,  eliminating  concerns  of  drive  sounds  being  picked  up  while  shooting video
