The Holy Grail of Calibration for Canon and specifically Nikon

 

Why is a Tamron lens calibration better than most other lens brands? One   of   the   biggest   issues   we   find   when   calibrating   lenses   with   Nikon cameras   is   that   Nikon   cameras   unlike   Canon   do   not   allow   you   add Autofocus   micro-adjustments   for   both   ends   of   zoom   lenses.   This   is especially problematic when calibrating the ‘holy trinity’ of Nikon lenses:

  • Nikon 14-24mm
  • Nikon 24-70mm
  • Nikon 70-200mm

 

This is because we have found that these three lenses tend to be the most inconsistent and thus need Autofocus Micro-Adjustments. The majority of the     Nikon   24-70mm’s   we   see     are   especially   prone   to   needing   totally different values as in – at WIDE and  + at TELE. Although   here   at   Cameracal   we   have   devised   a   work   around   which involves mapping the AF Fine Tune function to one of the programmable Function   buttons   (Fnct)   (we   also   calibrate   both   ends   of   the   zoom) this allows   the   user   to   quickly   change   the   AFMA   values   for   one   end   of   the zoom to the other. This is not always convenient though, especially if zooming quickly, this is where the  Tamron tap in console / dock comes in.

 

Tamron lens calibration

 

When Sigma brought in their ‘Global Vision’ line of lenses about five years ago, they also announced their Sigma Dock which allowed customers to customise their lenses. Fast forward a few years, Tamron also developed the   same   idea   of   using   a   dock   for   customers   to   ‘self-calibrate’   certain lenses (those in the G2 range). The   main advantage of the Tamron dock over that used by Sigma   (and by extension lenses) the fact the Autofocus Micro-Adjustments speak the same calibration language as both Canon and Nikon bodies. This means that more accurate AFMA result can be obtained by using Reikan’s FoCal, software.   This   calibration   software   product   is   considered   the   industry standard and typically yields far more accurate results. In comparison, Sigma Dock units are different to the internal camera units used from Nikon and Canon and there is no simple conversion factor.

When calibrating Sigma lenses using the Sigma Dock it is more time consuming with an element of trial and error to convert between camera units and Sigma Dock units The benefit   of   using   the   combination   of   Focal   and   the   Tamron   tap-in console   is   that   it   is   possible   to   calibrate   for   multiple   focal   lengths   and focus   ranges   and   input   these   into   the   lens,   thus   the   “Holy   Grail   Of Calibration”   This   is   even   more   sophisticated   than   the   Canon   lens calibration system, which allow you to calibrate for both ends of the zoom. The Tamron Tap –In console also allows Nikon users to over the one value only limit.

So   there   we   have   it,   next   time   you   buy   a   new   lens   please   do   look   at Tamron   (especially   if   you   are   a   Nikon   user)   as   you   may   just   get   more consistent focus, and sharper results, because of it! You can find out more about Tamron calibration here. With   regards   the   calibration   of   a   Tamron   150-600mm   G2   we   would undertake the following:

  • Check and upgrade firmware
  • 6 individual calibrations to the following focal lengths – 150, 200, 300, 400, 500 and 600mm

 

For our Tamron Zoom Lens Calibration Service there would be up to 6 calibration points along the focal range depending on the focal range of the lens. So for the Tamron 150-600mm G2 there would be 6 calibration points and for the Tamron SP 70-200mm F/2.8 Di VC USD G2 there would be 4 calibration points (See below)
