Bokeh and EFCS for the Fuji X-H1

November 22, 2018 - David Berryrieser - Leave a Comment

In the last post, I looked at the effects on Bokeh from EFCS with the Fuji GFX 50s.  Due to the ES (electronic shutter) and MS (mechanical shutter) operating in different planes, out of focus areas in an image can become distorted.  The gap between the two shutters can allow for preferential acceptance of some […]

Bokeh Shift Using EFCS on the Fuji GFX 50S

November 22, 2018 - David Berryrieser - Leave a Comment

In analyzing shutter shock, I wondered not just use EFCS (Electronic First Curtain Shutter) all of the time to avoid any sort image degradation.  With ES (Electronic Shutter), there are considerable rolling shutter effects to have to deal with if shooting moving subjects.  With EFCS however, the electronic shutter first clears the sensor, and in […]

Fuji GFX 50s Shutter Shock with 110mm F/2

Shutter Shock Methodology Demonstrated with the Fuji X-T2

November 18, 2018 - David Berryrieser - Leave a Comment

Shutter shock is an issue that has plagued early models of mirrorless cameras.  Unlike in a DSLRs, the shutter must wind to cover the sensor very quickly, then release.  This additional movement causes mirrorless cameras to be more susceptible to the shutter action.  DSLR cameras are not immune, and have their own host of problems […]

Optimizing Ball Head Choice Part III: Searching for Generalization

November 6, 2018 - David Berryrieser - Leave a Comment

In Part II of this series, we saw that each tripod has an optimal range of ball head sizes that complement the performance of the legs.  While legs are typically less stiff than heads, a head that is too small will materially diminish the stiffness performance of the system.  On the other hand, a head […]
