This is related to the 'Stylus 1 Best Compromise?' thread, but, that thread is going to fill up, so I made this a separate thread. Use of 2X is a compromise itself.
Many cameras have variations of in-camera extra zooms, with in-camera upscaling, processing, etc. (not digital zoom). They were crap in the past, but, I use Oly Stylus 1 2X, and Sony's variation called Clear Image Zoom. Both of these are an in-camera crop combined with in-camera creation of extra pixels, upscaling, back to full resolution: Oly 12mp.
After using Sony's 'extended optical zoom', and 'clear image zoom', I was hoping Oly had a similar feature, happily Oly Stylus 1 has 2X. Sony is Jpeg only, Oly 2X is Jpeg, and also available when shooting RAW, (not sure how that works)
I find them both 'effortless, good enough, for occasional, not frequent use'. They are primarily for Jpeg shooters, limited PP skills.
How about you?
use it? tried it? like it? tried it, ok, but don't use it; hate it, hate anyone who uses it? I'm looking for your opinions after trying it, not necessarily samples.

A bunch of blab
Keeping 'occasional use' in mind
Visible limitations: majority of people today view on monitors and hardly print, (if so, 8x10 on a home printer). My 23" monitor, full height is only 11" high, +/- 100dpi. If not pixel peeping, is it ok?
Related to compromise: a camera with limited range, with very good 2X, can compare favorably to a longer range camera with less successful, or non-existant 2X. That might let you get more out of a smaller camera. Or, like Stylus 1, use 2X to get more reach, thereby having the advantage of a larger sensor than typical superzooms. Or, in lieu of buying the tele 1.7X. I do both, 1.7x optical to 510mm, 2X to 1,020mm
Optical Crop: I know, and have seen many comparisons of optical, raw, subsequent PP cropping, out of camera upscaling, using 'real' computer and dedicated software. Most are equal, some are better, a few are worse. The better out of camera versions usually are combined with excellent PP skills, CIZ and 2X is not for those folks, and, they would use a real optical lens at that zoom anyway IF IT MATTERED.
Focus, Metering, Framing: One potential advantage of 2X or CIZ, over a subsequent optical crop, is that when the camera is 2X zoomed, both focus and metering are taken at that area, and you can see and frame something you might not even be aware of.
When comparing cameras, I always wonder: does Pany, Canon, Nikon, (whatever model a poster mentions), have a matching feature, and, if so, is it any good?
Implementation:
Sony's is 'on or off, progressive, beyond optical only'.
If on, it starts at the end of optical. You see an indicator scale, and, it starts after the lens stops moving, so you 'hear' it start. You can leave it on, but stop before using it easily, or occasionally use it.
Olys is on or off, instantly doubling any zoom length.
So, if at optical full wide 28mm, 2X on gives a 56mm start, progressively doubling any zoom length, i.e. 200mm becomes 400mm, to max of 300/2x600mm. A disadvantage is you may leave in on inadvertantly, (stays on when powered off/on) and use it unnecessarily within 28 to 150mm, or unwanted within 28 to 300mm. However, it has a great advantage of toggling on/off. When finding a bird in a far tree for example, you instantly zoom 'out' with a button press (turn 2X off) a larger field of view to find the bird, then a button press to engage 2X for the closer shot. I like that a lot. Instant, no motor noise, ..
There is a 2X symbol on screen, top left, I try to remember to check upon power on. I have taken many a mix of optical and in-inadvertent shots with 2X left on. They are so good I have to check the detailed exif to know. It shows the optical 35mm equiv, then you look for the digital zoom line, in Oly's case 1 for optical, 2 for 2X (n sony's case, progressive X numbers 1.1, 1.7, to max 2.0)

at this point, I should cancel the thread, but, here it goes, hope some will have something to say
