What's the equivalent lens for a cell phone?

When I got my first 8x10 years ago, I'd figure out what lens I wanted by equating it to 35mm. ("Hmmm, I want something like a 35mm lens, so that would be a 210mm...")

Today I was thinking about getting a wider lens for my 4x5, and thought "hmmm, I have a 90mm, which is like a 180mm on my 8x10, but if I got a 65mm, that would be like a 130mm on my 8x10..." Nothing significant, just for what it's worth...

Is that a 4x5 cellphone, or 5x7?

A pinhole. It's everything all at once and it's always in focus.

See all those little numbered buttons on the keypad? Those are zones 0 through 9. The zone system is so easy in the digital age...

Actually I think any cell phone camera is more aptly equated to a Holga...... with a bad lens.
