So what is Zero Shutter Lag (ZSL) and what’s good for? ZSL is when you push the capture button and you take a picture instantly without any delay at all, resulting in the exact image in the viewfinder that’s captured. Only expensive digital still cameras have had this luxury before.
ZSL is a term invented by Scalado and the first company being able to make it on a mobile device, back in 2008. ZSL now starts to come in more released mobile phones and devices.
In the video below ZSL is displayed together with Scalado Rewind, showing how to take perfect group photos. Watch the video below:
