A7r - Unusual memory card event
Aug 5, 2014

Sorry for the double post, pushed the wrong key.

I'm gradually learning how to use my new A7r.  Technique is important and I don't think you can get away with lazy.  Last weekend I had a day shooting in a village near me in Suffolk, England.  I'm familiar with the place and shot around 250 frames.  Once downloaded and processed I was dismayed to find I couldn't get any shot to be truly sharp and to display fine detail.  As I say technique is important but even I can't miss every shot with the three lenses I possess - FE35,FE55 and a old Canon 100mm fd.  So I wondered was my camera suddenly faulty?  Well, as well as the camera being common to all the shots so was the memory card.  I did a fairly rigorous test on all six of my cards and sure enough one the the cards produces files with a noticable slight blur and a loss of fine detail.  I can't recall ever hearing of such a thing happening to any one else but my gloom has certainly lifted.

Just for fun I attach some other shots that have maybe worked OK.
