Hey /p/, I need to make a video showcasing the zooming abilities of a lens. I am a bit of a photography noob so forgive me if this is a retarded question but why is it that a simple point and shoot like the Nikon P900 which sells for $500 has an 83x optical zoom meanwhile even the best "zoom lens" I can find for my a6300 is an 18-200mm lens which works out to about 11x optical zoom which is pathetic.
zoom lenses are for hacks who's legs are broken/ people who shoot sports and birds
zoom (variable focal length) directly correlates with sensor size. smaller sensor = more zoom. If you want, you can crop down that APS-C sensor to 1/2.3" size and get closer equivalent zoom but also lose MP because of the sensor design.

You on fire OP, follow your dream.
a point and shoot zoom is like looking at the moon through a paper towel roll then blowing that image up with commodore 64 8bit graphics and then painting it onto a football field with a weed sprayer filled with dog vomit.

Pick one, friend.

lmao
this is the kind of """""photographers""""" on /p/ handing out advice top kek
you don't understand, I need 1000mm lenses to make my art

There is always going to be a big trade-off in performance, size and zoom range. When you consider the tiny sensor inside of the P900 and it's low resolution of just 16mp, it's no problem to design a lens with such a long zoom that just barely meets the criteria for rendering an acceptable image.
That's not to say only shitty cameras can have a large zoom range, when cost is no object you can get similar to pic related, which in this case is an 86x zoom lens for broadcast use, although there are ones that go up to 100x as well. The trade off for having a pristine image at any point of its (equivalent) zoom range of 35-3000mm is a monster that costs $200,000 and weighs 24 kilos.
Dialing things back to more reasonable levels, the "sweet spot" for most zooms is up to 3.3x, which is why most "professional" zooms cover ranges like 24-70mm and 70-200mm. Ranges of 5-6x already begin to compromise on some aspects, and 11x lenses like the 18-200mm are called super-zooms and generally have poor performance near the extreme ranges of the zoom. Anything more would simply be prohibitively large and expensive if you also wanted to maintain sufficiently low distortion and a sharp image for larger sensor sizes.

when producing a quality zoom lense, a heavy zoom range is not a top priority. even worse, assuming a large zoom range it gets more difficult to come up with a lense design which also delivers good quality images.

Shame that the sensor itself isn't 645, still waiting patiently...

I own the p900. Carry & use it daily for the last 8 months.
One P&S that enables face shots of distant hotair balloonists & 5 seconds later a macro of bug shit. And all that potential in between. It gives me the moon.
Not once have I blamed the sensor for lacking ability.
That's the job of the monkey pressing the buttons.

say you have a fool frame with a 24-105, you have a zoom ratio of 4.4x (24/105=4.375)
if you have an m43 camera with the same lens, you get a 2 times crop factor and you get an equivalent focal length of 48-210, which still has an zoom ratio of 4.4x (210/48=4.375)
