I spend a lot in camera stores than I should. Even in electronic stores, I’ve seen these blister packed or boxed lens kits for camera phones.
Looking at them, I do feel a bit aggravated in the obvious attempt to pander to consumers. Most of the time, the lenses are designed for one particular phone. Phones do become obsolete after a year or two while actual cameras last for a while. Before I bought my camera, it’s been out for quite a while. I’ve see a bunch of absurd accessories on this side of the decade, it’s not the most dumbest accessory (Cough cough, the circle “handle” thing for selfies).
I’m still on the fence about these attachments to a phone. People buy phones more than camera, people sometimes change preference on the operating system or brands. I know for sure, I would change phones if there’s one that would benefit me for cheap (and if I have to renew my contract). So these “lenses” seem to be built around a gimmick to make everything look as good with a camera phone without a camera. I would prefer a camera or the camera phone any day for imaging. However the camera phone make sharing an instant photo quicker. In a way much to be the digital equal to the instant film camera.
Don’t make them, don’t buy them. Save up to 50 bucks and use the money to get something else…or a camera itself.
