* Note: As discussed above, the actual brightness values may be approximately 10% to higher than listed in this table (for comparison to other reviews), due to differences in the light meters being used.
The optics of this Epson seem to be very good to excellent. It’s interesting that Epson states that the zoom range is 2.1:1 same as many other Epsons (like the UBs), but the specs are otherwise different. Per the specs, there should be slightly less difference in brightness between wide angle, mid-zoom, and telephoto, and the measurements in this table back that up. It is clearly marked as a Fujinon lens, which is what Epson’s been using for years on their UB and some other projectors.
Since we primarily use mid-zoom brightness in most discussions, and there’s often a 10-25+ percent drop from closest to mid-zoom, then in this case if you can use the closest placement you won’t see as big a jump in lumens. In this case, only about 5%, and just 27% drop going from maximum to minimum zoom, while most previous Epson’s dropped over 35%.
