Thank you for this comparison, it was really interesting and helpful reading the results and all the feedback too. It would however as many pointed out in the thread be interesting to see the comparison measured in a more proper/typical dark HT room and using a projector more in line with what we also typically use in our home theaters.
I have a reasonable basement HT room with black back wall, black roof and black velvet side drapes, I would also welcome you for repeat test at your convenience in Espoo. The room is however far from as perfect as Marek's HT demo room in Helsinki, I just have too many light colored objects in the room, which can be removed of course.
You probably know Marek too, he sells your lenses after all and not too many do that in these parts of the Finnish woods
. Maybe he would be up to letting you use his nice HT demo room for a re-test too?
He has almost the complete current line-up of projectors from JVC, Epson, Panasonic, Sony and Optoma available in the demo room. He also has a very nice Stewart curved scope screen with motorized side aspect masking in the demo room and he has your HD-5000R lens setup on a JVC HD950 to demo the screen and lens setup. My point just being that it would all be very close to the conditions that the tough crowd in this forum are accustomed to. Can't hurt to ask if you could use it for a day for a re-run of the tests. Would save you from having to make a temporary dark draped room setup for the test and maybe if asking nicely he could also give you access to the projectors we would like to see this tested on. I assume you still have the Isco3 available?Side topic: Still a zoomer myself
I tried a borrowed HD-5000R some time ago in my current setup, still manually zooming though. With black back wall and by US standards fairly small scope screen (image only 260cm x 109cm Diag: 282cm [102.4x 42.9 Diag: 111], biggest size I could fit in my room) I did not necessarily need the lens for any additional lumen to be thrown at it. Plus with black background the black bar over spill from zooming to fill the screen never bothered me.
So the only points left for me were really the convenience and wow factor. Lately the convenience is becoming a bigger and bigger factor, I'm just getting fed-up with manual zooming and I need to replace my ancient projector very soon too. However, with only Panasonic and soon also the LCOS newcomers from Epson having zoom memories, choices still remain a bit limited for a lazy zoomer like myself. I would like to be able to consider at least JVCs new lineup as well, but as far I have found on the released specs there is no zoom memory on their new line this year either (sigh). Yes, I also consider remote controlled motorized zoom/shift/focus as manual, since I cannot do the switch at the push of a button. So it looks like I might have to start considering a lens again, thus I ended browsing this forum again, seems to be the place to go to...
