true, but its still manual. a mechanical shutter isnt required to manually control exposure. an iris would be nice so we wouldn't have the lame Portrait Mode artifacts. but oh wells
I could only find that Nokia phones ever came with a mechanical shutter
You wouldn't get any more pronounced shallow depth of field effects with a mechanical iris, because phone cameras are already shooting wide open.
To get a natural, shallow depth of field effect, you need a much larger sensor and a longer focal length.
As a photo/cinematographer, I'm just fine acknowledging that camera phones have become more serviceable largely through better software processing and less through more refined optics. That software processing is impressive, getting us stuff like good image stabilization, color rendering, etc.
But again, if I want to faff about with exposure settings, I have tools that satisfy that desire. For documenting what I see and posting to TEH GRAMS, my phone does just fine.
