Default Smart Lens clip-on for mobile – any experience?

I was in Walmart today and noticed 2 different offerings from tzumi, first a 3-lens fisheye/macro/wide set and second a 8x fixed telephoto.

I've seen these online and thought they were clever. So I grabbed one for just under $15, safe in the knowledge I could return it

Since it gets dark early and it's still dark, I did some quick shots in the kitchen:

•iPhone 6 with native lens at widest zoom setting
•iPhone 6 with native lens at full zoom
•Smart Lens+iPhone wide setting
•Smart Lens+iPhone full zoom

Here are my impressions:

Clipping the lens on an iPhone is a bit dorky because the iPhone's lens is so close to the edge, and you have to place it just right to minimize vignetting.

The Smart Lens has a manual focus adjustment, which is fun to use while at the same time the iPhone is trying to focus automatically.

It seems the iPhone's maximum zoom is 8x, since it matches the native magnification of the Smart Lens. But the iPhone pixelates badly at this zoom level, while the Smart Lens doesn't (but the Smart Lens has severe pincushioning). I’m not sure if this is progress or not! Maybe somewhat.

So! I'll play with this thing in the light tomorrow and decide if it's worth keeping. I can't see carrying the Smart Lens around without some sort of camera or carry bag (I don't always have a shirt pocket), but if I'm going to do that, I might as well bring the DSLR and 75-300 along...

I'm curious to know if anyone else has tried this thing.

PS: Holding the Canon zoom in front of the iPhone lens is not an option, ha!

Looks like your Smart Lens also has a bit of transverse chromatic aberration as well, as shown by the blue fringe across the bottom of the calendar and red/yellow fringe at the edge of the calendar's shadow. However, both of these problems can be at least partially reversed with a bit of post-processing, which is more than can be said about the resolution loss you get in the digitally zoomed iPhone. You can still read the dates fairly easily on the Smart Lens shot, but the digitally zoomed iPhone shot is hopeless in this respect.

Not sure quite what to make of the rainbowlike pastel coloring of the presumably white background in the non-zoomed Smart Lens shot.

Post hoc: Must be an artifact of the phone itself. I see a similar rainbowlike effect in the wide angle shot, where the bottom of the fridge has a red cast, going to green about the bottom of the freezer and going slightly reddish again near the upper part of the freezer door handle. I am also curious how you managed to hold the hold the phone steady enough to avoid motion blur despite the absence of a tripod socket on your phone.

Thanks scoundrel1728, the good news is it's not my lens anymore. It went back to Walmart the next day... Too rough for practical use.

If I want magnification I will use my Nikon L800 or Canon EOS Rebel and 75-300 zoom. I posted a separate thread showing the iPhone vs. DSLR where the Canon zoom was really helpful with a mountain shot.
