New shutter options
From those three nearly everyone will be setting the Hybrid mode as their default shutter choice for obvious reasons - It gives you the best of both worlds. If ELECTRONIC SHUTTER or MECHANICAL+ELECTRONIC is selected, shutter speeds faster than 1/4000s will be chosen automatically in Program AE and Aperture Priority AE or they can be chosen manually in Shutter Priority AE or Manual mode by rotating the shutter speed dial to 4000 and then rotating the command dial to the desired speed.
Selecting the ELECTRONIC shutter is of great use to photographers who need to shoot in complete silence and this is a very common need for a lot of working professionals especially in nursery’s, theaters, churches or movie sets (no more sound blimp necessary). For those who choose the ELECTRONIC shutter option, you do get the choice of adding some sound with the new SHUTTER SOUND and SHUTTER VOLUME options in the setup menu for a more positive shooting experience or muting the sound altogether.
There are a couple of drawbacks with the ELECTRONIC shutter though that you must be aware of before selecting it as your default choice. For starters it’s not recommended for fast moving subjects due to the rolling shutter phenomenon. Secondly because of the way the exposure is taken (line by line) erratic lighting such as with the flickering of fluorescent lights may cause fogging or banding effects. Also take note that the longest shutter speed is restricted to 1sec and ISO between 200-6400. You have been warned about the drawback of electronic shutters so don’t rush to blame Fuji for a weak product, though I’m predicting that there are going to be many such cases on the forums.
Last but not least, the mechanical shutter option will still be needed for many photography situations. Studio and advertising photographers will be selecting this option more than anyone else simply because any strobe or flash work cannot be used with an electronic shutter; they are technically incompatible with each other. The use of any remote triggers such as the popular Pocket Wizards won’t fire unless you have selected the Mechanical shutter option.
