A place to politely discuss the tools, technique and culture of photography.

This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.

Are those phone lens objectives the equialent of holding binoculars in front of a DSLR with an objective? (alien.top)

I never used them, so maybe I'm wrong, but aren't they just things you put in front of an existing regular phone camera (for example 24mm on the new Iphone) and then they just take a picture with a 24mm opening, but looking through whatever 120mm telephoto objective you stacked on top, without it having an effect on the photo quality?

In other words, if a 24mm opening can let a certain amount of light and information to the sensor, do the telephoto lenses change that somehow or is it literaly as if you pointed the phone through a binocular, since whatever passes through the telephoto then has to filter further through the standard 24mm lens?

I've got a homemade adaptor to put a phone onto my spotting scope.

Photo quality is variable. You need to zoom in or you get a circular back border (the inside of the scope)

Any vibration ruins your shot at distance. This even includes heavy walkers, using a timer is a must.

It's an absolute pain to focus.

You lose a lot of light.

Still fun to use.
