Tamron 35-150/2-2.8, E and Z mounts?
If you suspend the laws of physics then yes, such a lens might have some appeal. Unfortunately we can't suspend those laws and a 20-800 lens isn't practical. As one who asked for a 20-70 or 20-120 I was asking for something reasonable and potentially achievable. As an example, I'd actually like to be able to lift the lens and hand hold it. I'd like a reasonably fast aperture, f/4 or f/2.8 and some fine control of focal length.I am only an amateur. The question is what your dream zoom range is.
I see people answering 20-70, 20-50, 40-110?
Why not choose a very long zoom range like 20-800? In the question there were no restrictions mentioned, so if it would be technically possible without quality loss and in a very compact form, I would go for a 20-800 so I could capture everything close up and at a long distance.
I get it ... I was talking about a dream zoom range without any restrictions.If you suspend the laws of physics then yes, such a lens might have some appeal.

Of course the one I had in mind would only be 5 cm long and 250 g weight. Hey, but I was dreaming right!
Well, 20mm you can find them all around, all day long, but let's say, a 100- 500 ( 150- 750 mm APS-C) under a kilo, it could start at 4.5 or even 5.6, with a minimum focal distance under a meter, and/or with a magnification above 0.30 or even closer to 0,40If you suspend the laws of physics then yes, such a lens might have some appeal.

A 20-800 f/4 might be your dream but I would find it a nightmare, unless it could be under 2Kg and about 20cm long with a diameter around 100mm. Let me know when you can manage that please.
Why constrain yourself? Use the right tool for the task at hand rather than restricting yourself. I'd never try to use a Philips that needs a Flathead ...lol
It depends on ones concept of limiting. It could also be financial for some as well as convenience and weight. Many factors are involved depending on subject matter.
