Attention : Pixel Peepers. Quiz here
In reply to Adventsam, Apr 27, 2013

Here is a test for all of you arm chair experts. Pixel peepers of the highest degree.

After hearing all of the statements in this thread about OS or SS being better,  I decided to test the theory using my Sigma 120-400 APO HSM OS lens.  It has the OS or I can switch it off and use Steadyshot, or I can switch them all off.

These shots were taken from a tripod, using 2 second shot mode, aimed at a copy of a test pattern, lite with my wireless flash.  All were cropped to approximately the same size, and uploaded to my gallery on Dpreview.

Your challenge, if you decide to accept it, is to pick out the four photos, and tell which one was:

All stabilization OFF

All stabilization ON ! (Oh My) BOTH on at the same time, on a tripod!

Super Steady Shot ON

Optical Stabilizer ON

They are posted here in NO particular order.

Photo A

Photo B

Photo C

Photo D

You can post your guesses if you like,  I will post the answers in a few days.

Good luck, and good eyesight.
