Why do mobile phones find wide angle lenses so difficult?

We seem to be inundated with claims for zoom lenses on mobile phones, but who wants them? Zoom = blur! But getting everything you wanted included in the photo, especially for inside shots, is a major opportunity every company seems to want to ignore. W

Answers:

Two reasons. First, phone camera lenses are fixed focal length. Zooming is done digitally, which means the image is cropped and enlarged in software. As with any enlargement, there is a proportional loss of optical resolution. So if your phone had an extreme wide-angle lens, your "normal" shots would be digitally zoomed-in and therefore less sharp.

The other factor is that getting an extremely wide field of view adds both size and cost to a lens. To fit both size and price point of the phone, the camera has to make some compromises. if you need a wider view you can buy accessory lenses that will more than double your phone camera's field of view.

Maybe someday you will realize that a god damned TELEPHONE is NOT a real camera, and thus it has many restrictions that a properly designed from the ground up actual camera does not.

Not if you have in phone image stabilisation

Which. I phones from Apple have.

I wonder if they will increase megapixels

Like Sony have?

Very best wishes and enjoy photography.

The manufacturers have to draw the line someplace. It's not like phones have zoom lenses either - zooming on phones is done digitally. How much extra do you want to spend on a phone? Would you buy a $2000 phone that has a DLSR camera built in?

First, for clarity, zooms do not necessarily = blur. When you increase the focal length, you might have to increase the shutter speed to prevent blur. If you can do that, then you won't get any blur due to camera shake.

When you change the focal length, you change the perspective. The perspective is, in part, the angle of view, but it's also how the lens compresses or elongates near/far objects. Right now, smart phones have the equivalent of a 28mm lens, which is fairly wide angle. This focal length is intended for group shots, landscapes and architecture. It is not to be used for portraits due to the distortion of the perspective that these short short focal lengths produce. This is why so many people ask why the look ugly in photos. You didn't have that in the film days because those cameras all had zoom lenses. Plus, no one used them for selfies because you couldn't frame yourself. With just 24 or 36 exposures, do you really want to waste a few frames trying to get your face in the shot? Probably not.

When you zoom past the 50mm mark (in 35mm format) the lens will no longer stretch the perspective, but rather compress it. This flattening effect actually makes people look more attractive than they do in real life. This is why lenses in the 80-150mm range have always been considered portrait lenses.

Manufacturers like Apple, LG and Samsung do not put zoom lenses into their smart phones because of the added cost. Considering that the front camera module in the $1,000 iPhone X costs about $35 on eBay, and most other models cost around $8-$15, adding a zoom lens would increase the cost too much.

Back in the film days, having a camera with just a 28mm lens would be practically unheard of. Who would want a camera without a zoom? But today, the market proves its laziness once again. The market would rather have a convenient phone with a camera than to have a vastly superior camera as an additional item to carry. The reason, I assume, is that the average person simply does not care about the quality of their images nor do they care about doing anything other than selfies and snapshots.

If you want a camera with a zoom, you can add a zoom lens module to your existing phone, or go out and buy a real camera.
