I just meant that some people seemed to think that way about almost anything other than an ISCO.
Yeah, I get that, and thanks for your comments
I do get frustrated when people just assert something definitive without any hard data to back it up. Until someone actually tests a claim using some kind of blind or double blind standard, it's impossible to make any kind of definitive statement ("high rez audio sounds so much better!" or "product a blows away product b").
FWIW, I've shot out the UH480 with the ISCO III on several occasions, once with about 6 people in the room. It was hardly a controlled experiment, as one of the group was constantly switching out the lenses and was therefore aware of which lens was up at any given time. All we could do was ask that no one look behind them to see which lens was in front of the projector during the comparison. The result was that no one could tell which lens was which when watching reference HD material on a 144" StudioTek 130 in blackout conditions using a JVC HD990 projector. Seating distance was 12.5' back. When we did use test patterns, it was possible to see the difference in pincushion at the very top and bottom grid lines, and on one occasion where we tested an Optoma projector that had some chromatic aberration within its own lens, we could see the slight "smearing out" of the chromatic that was reported in the previous AVS shootout. Pixel sharpness and overall brightness appeared identical, however, and with HD video content the lenses were essentially indistinguishable.
Now of course I expect people to be extremely
skeptical of what I report here, since I still occasionally work as a consultant for Panamorph and can very fairly be accused of bias (although almost all of my Panamorph related work has been with CE manufacturers and major studios to get anamorphic video part of Blu-ray and next generation video, a project that - if successful - will benefit everyone, Schneider, XEIT, and ISCO included). I WANT people to be skeptical of my claims, just like I want them to be skeptical of the claim that one design or brand is somehow "automatically" better than another. I encourage a more controlled shootout between the two different lens products, and am happy to let the cards fall where they may when it comes to the results. My shootout was hardly double blind, although we did try to make it as "single blind" as possible. The only other shootout I know of is the one published here on AVS by HogPilot. I seriously do not know of any other. An ideal shootout would be one that was attended by representatives from all the major brands, with each lens set up properly and under best conditions. At that point their contributions to the proceedings would end, and it would be up to a group of qualified observers to make judgements based upon ideal real world viewing conditions.
Because I am so aware of the dual phenomenons of confirmation and expectation bias, I am skeptical of my OWN findings. We all tend to take in information that supports our own existing conclusions or biases and ignore information that contradicts them. This is an extremely hard tendency that it is extremely hard for us human beings to overcome. The only way I know of overcoming these tendencies is a test like what I describe above.
