Great for still life with no motion blur

It works well. The difference is clear once it starts getting dark and the ISO increases. I think it might be slightly over sharpened. However, the last update made using the app on my 5S very slow. Taking pictures used to be very fast. Now the exposure is about twice as long, requiring me to hold steady for about 4 seconds. In addition, processing time increased over 3 times (6 seconds). Not a big deal, but seems like a downgrade. Is this intentional in order to make it "higher quality" in the last update?
