<p>“We expect the 18-300mm F/3.5-6.3 DC Macro OS HSM to be yet another standout in our Global Vision lineup, and a perfect option for anyone looking to carry minimal equipment and still be able to capture breathtaking images” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “It will be a compact and affordable, high-performance, all-in-one lens that offers wide-angle to telephoto versatility and the very unique macro-zoom capability for close-ups. It’s perfect for all photographic needs – especially for those purchasing this product as their first time interchangeable lens.”</p>
<p>The lens offers a minimum focusing distance of 15 inches, with a maximum magnification ratio of 1:3. To enhance the macro capabilities of the lens, Sigma Corporation has also designed a dedicated close-up AML72-01 lens that pairs with the 18-300mm F/3.5-6.3 to offer a maximum magnification ratio 1:2 and changeable angles of view. Even when this close-up lens is attached, the image taken at maximum magnification ratio, at 300mm, infinity, shows very little difference in modulation transfer function (MTF). This close-up lens will be sold separately for $55 and will also be available in October.</p>
<p>The 18-300mm F/3.5-6.3 DC MACRO OS HSM incorporates a bigger and newly developed Hyper Sonic Motor (HSM) that ensures high speed and quiet AF. Additionally the Super Multi-Layer Coating reduces flare and ghosting, to provide the user with sharp and high contrast images.</p>
<p>The lens will be available in Sigma, Nikon, Canon, Pentax and Sony mounts; Pentax and Sony mounts will not offer OS.</p>
<p>The 18-300mm F/3.5-6.3 DC MACRO OS HSM is compatible with Sigma’s USB dock, allowing photographers to update the lens’ firmware and change focus parameters using Sigma’s Optimization Pro software. It is also compatible with Sigma’s Mount Conversion Service. Sigma remains one of the very few manufacturers whose products are solely made in Japan. Moreover, all products, including the 18-300mm F/3.5-6.3 DC MACRO OS HSM was designed to surpass the required quality inspection of every Global Vision lens with Sigma’s own modulation transfer function (MTF) “A1” measuring system to create a new optical standard to align with the high-spec cameras on today’s market.</p>
<p>The company will be exhibiting at the 2014 Photokina in Cologne, Germany, later this month. The latest lenses from the Global Vision lineup will be on display at the event and attendees are invited to stop by booth #B20/C29 in Hall 4.2.

<p><!--more--></p>
<p><strong>Teleconverters:  TC-1401  and  TC2001</strong></p>
<p>The  teleconverters  TC-1401  and  TC2001  are  developed  as  dedicated  attachments  for  Sigma  Global  Vision  lenses.  By  mounting  it  in  between  a  telephoto  lens  and  a  camera,  the  TC-1401  and  TC-2001  will  magnify  a  lens’  focal  length  by  1.4  and  2  times,  respectively.  Both  models  now  incorporate  Special  Low  Dispersion  (SLD)  glass  elements,  the  TC-1401  with  1  and  the  TC2001  with  2  SLD  elements,  which  offer  excellent  aberration  correction  and  maintain  the  exceptional  image  quality  of  the  original  lens.  The  TC-1401  will  be  sold  for  the  street  price  of  $349,  and  the  TC2001  will  be  sold  for  $399.  Availability  is  still  yet  to  be  announced  for  both  teleconverters.</p>
<p>The  teleconverters  come  packed  with  additional  special  features  –  its  power  distribution  is  designed  for  Sigma  lenses  of  large  diameter.  Without  affecting  the  lens  performance,  these  options  offer  stable  image  quality  through  the  zoom  at  every  focal  length  and  on  the  corners  of  the  frame.  Additionally,  the  tele  converters  are  designed  for  high  durability  –  being  both  dust  and  splash-proof.  These  new  teleconverters  are  capable  of  shooting  effective  AF  at  F8,  if  the  camera  can  do  so.</p>
<p><strong>Filter  lineups:  WR  Protector,  Protector,  WR  UV  Filter,  WR  Circular  PL  Filter</strong></p>
<p>With  the  new  Global  Vision  lens  filters,  Sigma  will  now  offer  13  filter  size  options  in  four  new  lineups.  These  filters  offer  several  new  features  that  enable  photographers  to  maximize  the  optical  performance  of  Sigma’s  lenses  in  various  conditions.  The  filters  will  be  available  for  purchase  in  October.</p>
<p>These  filters  have  a  new  design  that  suits  the  high  optical  performance  of  all  new  Global  Vision  products  to  prevent  vignetting  or  the  decrease  in  peripheral  light  quantities  especially  when  the  thinner  wide  type  filters  are  used  with  Sigma  lenses.  By  incorporating  Sigma’s  Super  Multi-Layer  Coating,  the  filter  reduces  flare  and  hosting;  black  rimmed  glass  eliminates  unnecessary  internal  reflections,  and  provides  high  performance  for  both  digital  cameras  and  film  cameras.  In  addition,  to  ensure  versatility,  Sigma’s  WR  filters  feature  excellent  water  and  oil  repellent  as  well  as  an  antistatic  function,  and  the  two  types  of  “Protector”  can  protect  the  lens  surface  effectively.</p>
<p><strong>The  four  line  ups  include:</strong></p>
<ul>
<li>WR  Protector  (Water-repellent,  antistatic  type)  and  Protector  (normal  type):  The  protector  is  developed  to  protect  the  lens  surface  from  dirt  and  dust  as  well  as  scratches.  It  is  an  ideal  filter  for  regular  use  as  it  is  completely  colorless  so  it  does  not  affect  color  reproduction.</li>
<li>WR  UV  Filter  (UV  water-repellent,  antistatic  type):  UV  filter  prevents  the  bluish  tone  that  generates  by  absorbing  ultraviolet  rays.  It  is  effective  in  most  situations,  such  as  landscape,  portrait  and  general  photography  on  a  sunny  day.</li>
<li>WR  Circular  PL  Filter  (PL  water-repellent,  antistatic  type):  Circular  PL  filter  removes  the  reflection  of  water  surface  and  glass  windows,  and  increases  the  contrast  in  landscape  photography.</li>

<p><strong>September  12,  2014,  Saitama,  Japan.  –  Tamron  Co.,  Ltd.</strong>  (President  &  CEO:  Morio  Ono),  a  leading  manufacturer  of  precision  optics,  announces  development  of  a  new  ultra-wideangle  zoom  lens  for  full-frame  DSLR  cameras  with  a  fast  F/2.8  aperture  and  VC  (Vibration  Compensation),  the  world’s  first  in  its  category.  The  price  and  launch  date  are  to  be  determined.  The  lens  will  be  showcased  at  the  Tamron  booth  at  Photokina  2014,  September  16-  21,  2014  in  Cologne,  Germany  (Photokina  Booth  Number:Hall  4.2  D10  –  E19).</p>
Since  2012,  Tamron  has  been  expanding  its  lineup  of  interchangeable  lenses  for  35mm  full-frame  DSLR  cameras.  SP  24-70mm  F/2.8  was  the  first  in  the  series,  being  integrated  with  VC,  followed  by  the  70-200mm  F/2.8,  90mm  F/2.8  Macro,  and  150-600mm  F/5-6.3.  The  array  of  those  new  lenses  have  been  highly  acclaimed  among  the  photo  enthusiasts  and  working  pros  around  the  globe.  To  address  the  needs  for  more  towards  the  wider  angular  field,  Tamron  spearheaded  the  development  of  SP  15-30mm  F/2.8  Di  VC  USD,  a  fast  ultra-wideangle  zoom  lens  with  the  image  stabilization  feature,  setting  itself  apart  from  the  rest  of  zooms  in  this  category.</p>
<p><!--more--></p>
<p><strong>Product  Highlights</strong></p>
<p>Superb  image  quality  and  performance</p>
<p>With  an  optical  construction  of  18  elements  in  13  groups,  inclusive  of  XGM  (eXpanded  Glass  Molded  Aspherical)  element  placed  at  the  front  group  and  several  LD  (Low  Dispersion)  glass  elements  in  the  system,  aberrations  such  as  geometrical  distortion  and  lateral  color  are  efficiently  compensated  for  enabling  the  zoom  lens  to  deliver  outstanding  image  quality  throughout  the  entire  range  from  corner  to  corner.</p>
<p><strong>Prominent  competence  of  VC  when  shooting  night  scenes  and  under  low  light  conditions</strong></p>
<p>Recognizing  the  needs  for  image  stabilization  capability  on  a  wideangle  lens  voiced  by  a  number  of  photographers,  especially  for  a  full-frame,  fast  F/2.8  ultra-wide-angle  zoom  lens  category,  VC  is  tuned  for  providing  discernible  competence  throughout  the  entire  zoom  range.  The  feature  enhances  image  depicting  capabilities  for  shooting  night  scenes  and  under  low  light  conditions.</p>
<p>B<strong>enefit  of  the  eBAND  and  the  improved  BBAR  coatings</strong></p>
<p>Tamron’s  acclaimed  BBAR  (Broad-Band  Anti-Reflection)  coating  is  further  refined  to  render  uniformity  in  transmissivity  across  the  critical  bandwidths.  Coupled  with  the  eBAND  coating,  ghosting  and  flare  typically  observed  on  ultra-wideangle  lenses  are  efficiently  eliminated,  resulting  in  crisper  and  crystal-clear  images.</p>
<p><strong>Fluorine  coating  on  the  front  element,  Tamron’s  first</strong></p>
<p>Due  to  the  large  diameter  and  the  prominent  convex  profile  of  the  front  element,  it  is  not  practical  to  deploy  a  protective  filter.  For  the  first  time,  a  fluorine  coating  is  applied  to  the  front  element,  which  repels  water  or  any  type  of  dirt,  while  making  it  easier  to  remove  such  smudge  when  contaminated.</p>
<p><strong>Fascinating  background  “bokeh”  with  the  fast  maximum  aperture  of  F/2.8</strong></p>
<p>Natural  and  smooth  blur  on  the  subject  background  enhances  depictive  capabilities  of  wide-angle  photography  when  a  subject  is  located  in  the  close  distance.  The  9-blade  diaphragm  construction  retains  a  near-circular  aperture  opening  even  when  stopped  down  by  two  steps  from  its  full  open  position  and  delivers  ideal  bokeh  effects.</p>
<p><strong>Easy-to-use  autofocus</strong></p>
<p>Speed  of  autofocus  and  control  accuracy  are  further  improved.  USD[4]  (Ultrasonic  Silent  Drive)  delivers  tack-sharp  images  due  to  the  high  torque  and  fast  response  speed  with  least  amount  of  lag  time,  yet  with  extremely  low  acoustic  noise.  Equipped  with  a  full-time  manual  focus  mechanism,  fine  focus  adjustments  are  enabled  without  exiting  from  the  AF  mode.</p>
<p><strong>Comes  with  “SILKYPIX  Developer  Studio  for  Tamron”,  RAW  image  processing  software  customized  for  Tamron  SP  lenses</strong></p>
<p>The  SILKYPIX  Developer  Studio  software  provides  an  added  feature  to  generate  high-quality  images  from  RAW  data,  while  performing  adjustments  to  reflect  a  personal  style  and  a  taste  of  the  photographer.  These  include  white  balance,  color,  sharpness,  and  the  tonal  curves  recorded  by  digital  cameras.</p>
<p>The  SILKYPIX  Developer  Studio  for  Tamron  provides  a  range  of  functions,  in  addition  to  the  basic  adjustment  capabilities,  such  as  correcting  aberrations  (lateral  color,  distortion,  relative  illumination  fall-off)  referring  to  the  optical  design  data.  Optimal  use  with  Tamron’s  SP  series  lenses  –  renowned  for  their  high-depiction  capabilities  –  delivers  images  that  meet  photographers’  most  exacting  demands.</p>
<p>[4]  USD  (Ultrasonic  Silent  Drive)  is  Tamron’s  proprietary  ring-type  ultrasonic  motor.</p>
<p><strong>Detailed  Feature  Explanation</strong></p>
<p><strong>VC  (Vibration  Compensation)</strong></p>
<p>VC  (Vibration  Compensation)  is  Tamron’s  proprietary  image  stabilization  system.  Tamron’s  VC  is  a  three-coil  system,  whereby  three  driving  coils  activate  the  shake-compensating  VC  lens  group  electromagnetically  via  three  ceramic  ball  bearings.  The  VC  lens  elements  are  held  in  place  only  by  contact  with  the  ceramic  ball  bearings,  achieving  smooth  movement  with  little  friction.  And  since  the  VC  mechanism  is  moved  in  parallel  using  only  the  motorized  control,  the  mechanical  structure  has  been  simplified,  enabling  the  development  of  a  more  compact  lens.</p>
<p><strong>The  Ultrasonic  Silent  Motor  (USD)</strong></p>
<p>In  the  ultrasonic  motor,  a  piezoelectric  element  arranged  in  a  ring  formation  generates  ultrasonic  vibrations  in  a  metallic  ring  stator,  and  the  vibration  energy  is  used  to  rotate  a  metallic  ring  rotor  that  is  attached  to  the  stator.  The  rotation  energy  is  in  turn  transferred  from  the  metallic  ring  rotor  to  operate  the  focusing  mechanism  of  the  lens.</p>
<p><strong>eBAND  (Extended  Bandwidth  &  Angular-Dependency)  Coating</strong></p>
<p>eBAND  Coating,  developed  by  Tamron,  is  a  new  coating  technique  that  radically  improves  anti-reflection  properties.  A  nano-structured  layer  (1nm  =  1/1,000,000mm),  with  dimensions  smaller  than  the  wavelengths  of  visible  rays  of  light,  is  deployed  on  top  of  multiple  coating  layers  to  maximize  efficiency.</p>
<p>Reflections  occur  at  the  interface  between  the  lens  and  the  air  because  of  the  difference  in  refractive  indices  of  the  two  substances.  The  nano-structure  of  the  eBAND  Coating  renders  an  extremely  low  refractive  index  by  minimizing  the  differential  with  that  of  air  while  actively  inducing  air  to  its  own  structure,  thus  significantly  suppressing  the  extent  and  degree  of  reflections.</p>
<p>In  addition,  a  total  anti-reflection  efficiency  at  the  lens  surface  is  further  improved  by  means  of  integrating  the  conventional  coating  technique  based  on  an  active  utilization  of  the  “interference  of  light”  principle,  attenuating  an  amount  of  reflections  by  overlaying  reflected  light  on  the  coating  front  surface  and  that  of  the  back  side  with  its  phase  shifted,  thus  increasing  the  net  transmissivity.</p>
<p>As  a  hybrid  technology  between  the  newly  developed  nano-structured  layer  with  an  extremely  low  refractive  index  and  conventional  multiple-layer  coatings,  the  eBAND  Coating  provides  superb  anti-reflection  performance,  delivering  crisp,  razor  sharp  images,  and  remarkably  eliminating  the  flare  and  ghosting  that  can  tangibly  damage  image  quality.</p>

<p>All  of  Sigma’s  Global  Vision  lenses  are  compatible  with  the  company’s  USB  dock  and  Mount  Conversion  Service,  and  undergo  individual  testing  before  being  shipped.  Using  the  USB  Dock  allows  for  advanced  customization  of  AF  speed,  OS  viewing  modes,  focus  limiter  and  firmware  updates.  Every  Sigma  Global  Vision  lens  is  tested  with  Sigma’s  proprietary  “A1”  MTF  measuring  system  prior  to  shipping  to  ensure  optimal  performance  and  image  quality.</p>
<p>The  company  will  be  exhibiting  at  the  2014  Photokina  in  Cologne,  Germany,  later  this  month.
