Optoma ZU720T VS ZU720TST: why pay more on short-throw lens

Now, let's dig deeper a bit more. When a projector's measure of the total visible light emitted by a its lens per unit of time climbs over 6,000 lumen, most manufacturers start offering detachable lenses. The word 'flexibility' gets thrown around by the sales people.
The logic applied is -- since you have doled out $8,000 to $10,000 for the projector -- you can afford to throw in another $2,000 to $3,000 for a detachable short-throw, normal or long-throw lens.

Who is a good fit for Optoma ZU720TST?
Optoma ZU720TST is less bright -- because of its short throw lens. And it's more expensive for that same reason -- its short throw lens.
Any lens is transparent only to a certain point. Visible light always dissipates in a complex projection scheme. The brighter the lens the more costly it is to make it. Short-throw projectors offer a smaller max picture size, making such devices a no-go for larger outdoor movie screens like these or these. By the same logic, ultra short throw projectors offer max 150" diagonal, by and large.
Which one to choose: Optoma ZU720T or Optoma ZU720TST?
The rule of thumb when choosing between ZU720T and a comparatively slightly costlier ZU720TST Optoma projectors is: when having plenty of space at your outdoor screening venue you end up paying less for a brighter T version projector. 'T' stands for 'Telephoto'.
If you want or need the projector closer to the screen -- be ready to sacrifice some brightness with the TST version and opt for a slightly costlier ZU720TST.
Here are some insights in parting. The bigger the projection surface, the further you need to place your projector from the screen, and the less concentrated visible light will be projected on it.
Take a 20' x 11' screen as a case in point -- like this inflatable by Open Air Cinema. The most distant wall is 40 ft away. А normal throw lens will call for a projection arrangement where the projector is placed at an 80 ft distance. But it's not possible. So this becomes a short throw projector situation.
Projector or LED display for Your outdoor events
And here is an illustration of a case where the screening event venue called for a long-throw lens:
But -- due to a limited budget for the outdoor movie screening -- a short throw projector was used, right in front of the inflatable screen.
