Buy an anamorphic lens or projector with more zoom?
I own an Epson HC2100 projector and a 127" Silver Ticket 2.35:1 screen. After I moved, I learned my throw isn't short enough anymore. The most I can throw is 120" but I need to throw 135" and a minimum of a 100". The most suitable projector I found for this is the BenQ ht4050. I could zoom in when I want to watch movies and zoom out when I want to watch TV. However there's another option, I could take the 100" screen that I project right now, even though the Epson HC2100 doesn't have an anamorphic option, I could figure something out with my PC, and buy a used panamorph lens like a uh480.
Ultimately would I benefit more from putting another layer of glass in front of the projector lens, but having more light output and pixels? Or just having one layer of glass for the projector, yet losing light output and pixels on the top and bottom?
With the ht4050: I would still have a full 1080p image for 16:9 content. Also, it has a glass lens and probably better PQ than the Epson.
With the Panamorph lens: If i just need to throw 100", I'll have more choices for projector upgrades in the future, not having to worry about zoom level. For staying 1080p anyway. An older Panamorph probably won't work as well if i upgrade to 4k.
What would you do in my shoes?
