Watch me, Tom. I can pick apart your posts, too.
Big difference. The fact that it's a lens just makes it easier to take videos with.
Yet my argument was that it was hard to track moving bodies with telescopes. I didn't say anything about camera lenses.
What
is your point? A lens is a series of glass elements that focus light onto an imaging sensor. It's got a barrel and everything, just like a telescope does. And you can mount it on a tripod.
It's also easy to focus on a plane looking through a sheet of glass. Looking at a plane through a sheet of glass wouldn't compare to looking at it through a telescope.
You couldn't be more wrong about this. If anything, a telescope is a "sheet of glass".
As shown here, a modern telescope has only 3 optical elements (4 if you count the objective piece). Any modern lens has at least 8 elements or more, including aspherical and anti-reflective elements to prevent against aberrations from the light diverging.
As you can see, it's actually the telescope that's simply a "sheet of glass"; the lens is a piece of technology. Don't confuse that.
Also, with the right equipment (a very sturdy tripod), it might even be easier to shoot a video of a plane in the distance because it would appear to move slower than one flying straight above you.
No. The slightest tremors and movements of your hand prevent you from tracking far off moving bodies.
Clearly not.
And if it were out in the distance, with the right kind of tripod, you can get the plane in view with ease. It's much easier to focus on something
not moving a lot, than something that
is moving a lot. Right?
If you have a camera at the business end, then what's the difference?
Looking through a telescope exaggerates the slight movements of your hands and decreases precision of movement.
True. So do lenses. The difference is, telescopes tend to be larger and
longer than telephoto lenses. The whole idea of a telephoto lens is that its actual length is shorter than the focal length. So what's your point? Tripods will solve the "precision of movement" problem.
A plane in the distance would be easier to track because it would appear to move more slowly than a plane directly overhead.
It would be harder to track because the telescope is focused on an extremely small area of the sky, which you need to track with millimeter precision.
Again, telescopes and lenses are basically the same thing, except lenses are made with more glass and refine the light before it reaches the image sensor.
Also, tripods.
