wow, so spam shake the hand and capture also no problem right ??
because i want to use GNex as my primary camera ><
I'd recommend against using the Galaxy Nexus as your primary camera, if photography is of concern. Taking snapshots still ok, but for photography purposes, a big fat no. Sensor just not up to the job.
Zero shutter lag has nothing to do with image blur. Zero shutter lag only concerns the process after the shutter button is released, and the image being captured. Shutter lag concerns whether you capture the exact moment that you want (like you want to take a pic of a moving car in the centre of the frame, a huge shutter lag will cause the frame to totally miss the car, while a short shutter lag will let the sensor capture the image just as you want).
Image blur has to do with shutter speed (not to be confused with shutter lag). Shutter speed is the duration which the sensor is capturing the image. Think of light as particles (which it is in quantum mechanics), and you are capturing an image which only has a big dot in the centre. If the sensor is as still as possible, then the light will only hit a fixed place with little variation (clear image) and you get a clear dot in your image. If the sensor is shaking, the particles will land in a scattered area (blur image) and you get a dot with blurred edges.
To make it simple, the process of taking a picture on any camera:
1) Shutter button is half-pressed, lens focuses (in this case, you press the on-screen shutter button on your phone)
2) Shutter button is pressed fully. (in this case, you release the on-screen shutter button on your phone)
3) Shutter opens.
4) Sensor is activated for capturing image
5) Sensor is deactivated (shutter closes) and processing of image begins
6) Image is processed and is saved
7) Sensor ready to capture the next photo.
Shutter lag is between 2) and 3) [since phones don't have shutters, shutter lag concerns from 2) to 4)]. Shutter speed is in step 4). Shutter lag is the primary reason why people buy DSLRs.
Hope that helps.
Apologies for the wall of text on shutter speed vs shutter lag. Too many people are using the wrong term.
