OK - so maybe I'm being a bit harsh, but I'm feeling somewhat underwhelmed at the moment: - They're all very "modal" - they run in their own little world and have their own settings - basic stuff like filetype/quality, size, drive mode, metering mode etc. Why? - They seems picky about what mode you're in (e.g. the touchless shutter doesn't work with my Memory 1 setting). - They don't work well with back-button focus (e.g. Remote Control doesn't focus at all and Touchless Shutter just tells me that C3 (my assigned button for back focus) is "disabled"). - Availability across cameras is patchy (e.g. Light Trail only works on A7S and A5100) - To use the free ones you still need to logon to the Sony Entertainment Network - Some apps don't support raw (e.g. light painting) - Some stupid limitations - e.g. Neither Smooth Reflections nor Touchless Shutter will work with full electronic shutter (silent shooting). It also disables the centre button on the dial - the one that let's you move the focus point! - Can't combine apps - e.g. Smooth Reflections with Touchless Shutter On top of all that the prices of some of them are a bit crazy - £7.99 for timelapse. Are they serious? So, IMHO - all a bit lame.... A flawed idea.
