Shuttershock on the A7r… shhh utter nonsense?

The deadly shutter shock issue on the increasingly popular Sony A7r just won’t go away. The reasoning behind it, is shaky at best….  I would like to dispel some myths and perceptions immediately.  Many people are making way too big a deal of this.

  • Concern is limited to, or prone to, longer focal lengths.  An increased vibration occurs, period…(read further about complexity and severity).
  • The camera doesn’t know how long of a lens is(physically) attached to it.
  • It can’t tell how much it weighs.
  • The 1/100th of a second “problem” area, doesn’t care what’s there taking pictures….
  • The camera mechanism itself, behaves exactly the same, every time, at a constant shutter speed… hmmm
  • Shutter doesn’t try harder because an AF, IS lens has higher electronic requirements.  In fact many of the adapters don’t even have electronic connections.  This logic really baffled me.
  • All A7r’s have this problem?  Nope…  Vast majority of people have no complications…

Some things that do make sense for this issue.

  • Poor tolerances on a myriad of adapters.  Early models had higher incident rate due to faulty mount on camera(light leak too).  They ain’t fittin too good.
  • The 36mp sensor requires near perfect execution to get a good shot.  Person isn’t shooting too good!
  • Communication between lens, adapter, camera, IS, AF, mount balance, or any combination of those, is complicated & can cause problems which are really unrelated.  Margin of error not too good….
  • The A7r has increased internal vibration at some shutter speeds that are easily compensated for.  Camera is good….
  • continued banter… is no good…

People have argued, proved, disproved, tested, complained and gone to great lengths trying to fix or explain this “problem”(see Joseph Holmes/Ferrell McCollough/Ross Hamamura and others).  Personally, I have never experienced anything that even slightly suggests an issue.  I own 2 A7r’s.  Blurring that’s occurred is easily attributable to my own operator error.   I will state that I don’t shoot many lenses over 200mm and am 98% manual settings & focus.  I do have several lenses that weigh over 700g.  When below 1/200th I tend to use a tripod and use a wireless Sony remote.  Varying conditions may require more stability.  This is not news to any high performance camera system.  Throw a 300mm lens on the D800e, it’s going to require more attention(experienced that.)  An IQ 280 on 645DF+ damn near sends out a shock wave!

I’m not sure why people propagate this.

Two very weighty lenses. Both top performers at any shutter speed on A7r. Used here with Metabones IV and RJcamera EF to NEx adapters.

Perhaps not crowd pleasing final thoughts.

  • Many really good photographers don’t realize the precision needed to capture perfect clarity on the 7r.  It’s hard…  Suppose to be!
  • It took me over 10,000 captures to get the D800e.  I’m up to around 4,000 on the 7r and have improved my percentage of reasonable photos.
  • Use the right camera to get desired results… BIG ONE!
  • Metaphor for the day…  If your car shimmy’s at 70mph and you continue to drive at 70….  –get tires balanced/aligned– (adapter, stabilize platform, change settings, etc).
  • Don’t write articles about your car shimmy… or post repeatedly in forums.  It is really a specious criticism.
  • The A7r is the ultimate, compact mirrorless camera.  Full Frame 36mp resolution, endless lens choices, developing native lens line, and lightweight. This isn’t a deal breaker, it’s more of a botheration.
