good article to read
iPhone 7 or 7 Plus to buy
seriously zoom not useful in daily
btw what is bokeh effect ? I do google it don't know what it talking about
summoning sifu Andrewtst help explaining tqvm
Zoom is extreme useful as sometimes we want capture the thing where possible we can't reach the destination to get it.iPhone 7 or 7 Plus to buy

Optical Zoom is hardware zoom which can maintaining as clear as without zoom. Digital zoom wise is software simulation zoom.
The iPhone 7 Plus after 2x optical zoom is move to digital zoom, this is no choice, else the camera will be superb long, they can archive 2x optical zoom already is something really great.
Read this for bokeh explanation, in short summary blurring the background to stunning out the focus object - https://en.wikipedia.org/wiki/Bokeh - this is where the most people love it as it just simply look beautiful where human eye can't really see it. Bokeh in previous only DSLR can archive it but now mobile also can get similar result but is a mixed of hardware + software, not like DLSR which is purely hardware by lens where bigger aperture lens can generate much extreme feel of bokeh effect, or another way to get it is using telephoto lens which having a big optical zoom.
iPhone 7 Plus second camera is a telephoto lens which have 2x optical zoom, in general it can't really can get outstanding bokeh effect, that the reason why some software simulation is involved, but at least it still got 2x optical zoom, with it smart ISP calculation (software simulation), thus it can produce a nice look bokeh effect.
In another word, Bokeh effect is where the lens produce a shallow depth of field (DOF) - https://en.wikipedia.org/wiki/Depth_of_field, which means the background is blur and only the focus object is clear. It can archive in two way, a very big aperture lens or very big optical zoom telephoto lens. Combination of two can get something extreme shallow DOF. Mobile wise often involved with some software to emulate out due to it limitation where impossible to put something that big lenses in mobile.
