HD10E found on Sony1292-s are not even considered the same as the later HD10Es found on the G90... The 1292 and the G90 both had HD10F lenses. The G90 had a later version that is superior to the lenses from the 1292. I am not aware that the G90 ever had HD10E unless modified by the owner. Indeed, my bad... |

I have two sets of HFQ900 here, one set does what you said with reflections, and the other set does not. The newer ones i have here have got a Delta sticker on them with all the details, just like the one seen on the HD-145s etc... The ones on my CineMAX only have a silver sticker saying HFQ900... So which of the two did you find was the better performer; the Delta sticker or the silver sticker? I assume you played around with moving the lenses from tube to tube. Even within the same set you can find difference from lens to lens. |

I wouldnt say either were sharper than the next, just one set had the halo and one did not.

Oh man I have to tell this. I got a set of Barco HFQ900 and I got a great feeling when trying them on another projector. So now I compared with the GT17 on the Marquee and it is absolutely true that the HFQ900 are more uniform over the total area into the corners. It even seems the colours a little less saturated but i want to measure that one day to be sure. I never had HFQ900 with the coating on them and no way I am going back to the GT17. I might give them to someone to test one day close to me. The whole picture looks simple more photographic, sharp and uniform. I am writing this on the Marquee and the characters look much much more black than I am used to  |

I have ones with only a silver sticker now saying HFQ900.
My opinion this is almost as big an upgrade as the MP boards. The lenses are possible the most important part of any projector.

Ill be happy to trade a set of my 2003 build HD10E lenses for a set of 2003 or later build GT17. Or sell a few sets for 1500$ each.
If you can resolve the 1:1 pixel phase pattern on the HD basic disc on screen you cant ask for better optical resolution, i still miss to see the HD10E or HD10F do that, i have seen the GT17 and the2010 build HD10L do that on a 90 and 110" screen.
Im using a set of 1999 build GT17 on my 90" and have 8 set of HD10E, 4 set of HD10L 1 set of HD10F 1 set of HD10 and 2 set of GT17.
The battle betwen the GT17 and HD10L was close, and came down to focus uniformity, where the HD10L was a bit off around 60cm from the center.
I still miss to test the HD10E on a bigger screen.

I do not know what you have. Might be HD10E are not the same as HFQ900 from Barco? Wolfman had 2 HFQ900. I looked up an old email discussion I had with Mike Parker.
me:
I have the GT17 but on the Barco I have the HFQ900 so I can try both.
mike:
The HFQ900 are the best. The GT17's are what I have, but the HFQ900are truly better. Are your HFQ900 lenses labeled as such?
me:
They are labelled Barco HFQ900HM
mike:
Yes, you have a good set of lenses
Notice Mike asking for the labelling! Perhaps he knows more about the HD10E that are not labelled as HFQ900?

This is a picture of my 3 types of lenses. The HFQ900 do really have HFQ900 written and not HD10E. My both HFQ900 do have plastic front exactly the same. Both come from 2001 Barco models. The golden sticker came with a Cinemax and I think only the sticker is different.  From this post below (and pictures) I understand that Barco also used hand picked HD10E modified? This might hve started the confusion that the HD10E are the same as HFQ900? www.curtpalme.com/forum/viewtopic.php?t=2761 |

There has been huge amounts of confusion about lenses true time, and i dont see any changes, people speculate and guess, and some will still try to make the HDF900 rare/ special, caling it special selection, and quote from old posts. Ill get hold on a set of HFQ900 lenses, and compare it to some of my late HD10E lenses. I have seen HFQ900 lenses, but not done a direct comparison, i never was impressed with what they did, later lenses might have a improved ansi contrast due to less internal light reflections. Af all the lenses i have, the only one with out of focus corners is the HD10, the others will all do perfect corner focus on my screen, compared to the center. I think the corner focus has more to do with glycol and flare/ stig setup than lenses in general, the difference i find is more about overall resolution and uniformity looking across the hole screen. The HD10L lens seen on the pic was focused on a 110" screen, see how centered the adjustments are, thats a sweet lens, and did resolve the pattern on screen, about as good as it looked on the tube face.  What test pattern do you use to evalate and adjust optical focus.? |

It is difficult to see with a test pattern but I had the smpte testpattern and looked at the corners. I tried to make pictures but you have to hold the phone at exact the same distance. Not possible. When I had changed green I saw the difference between red and green and green was a lot sharper in the corner. Now I checked a minute ago and the difference between green and red is not in sharpness but in the corner red is vertical better and green horizontal. So what I am saying is that I think I see it in the testpatterns but can not make a iphone picture of it and do not care enough to use a better camera. I just watched a small part of doctor who and the difference is obvious judging from my memory. The black characters are also blacker might very well be a coating issue. GT17 is out for me I have a 100 inch screen. |

Wait a moment. Black is not blacker when it is full screen but when it is in the characters on the desktop. That means this lens has better ANSI contrast like you said possible caused by the coating. That might be measurable with a checker block pattern.
The upgrade was really comparable with having MP boards for the first time. They also improve the ANSI.
I cannot compare with my other HFQ900 because they have no coating at all on the front part. I only remember that after those my GT17 looked the same or better.

Comparing green to red is like comparing appels with bananna, you have to compare on the same tube swapping lenses, so you know whats tube and whats optical related, the drive on green is much higher and can not be compared with red and blue, as there is much more light traveling true the lens. And you need to perfect lens flapping to each lens you test.
The SMPTE is a terrible pattern for optical resolution, you need something more complex, that is more on the edge of the lens resolution.
I used a grid pattern and the smpte pattern once testing the GT17 against the HD10F lens on the SONY G90 as was not able to detect a difference, that was a hole different story on the marquee with the right test patterns and a high bandwidth video chain with perfect focus adjustment. The HD10F was judged as a low resolution lens not capable of resolving 1080P, worse than the HD10E, on a 90" screen, wich also makes sense looking the lens specs of the HD10E
The HD10E might show better performance over 110", ill think it needs 200" to hit the sweetspot, way above HT preference, there is a reason they used the HD10E for planetariums shooting 10-12m away from the scren/ dome. Its a lens optimised for laaaarge screens.
If you like to compare lenses, make sure your magnetic adjustment and focus is perfect, try separate the test in different parameters like resolution uniformity, and contrast, so you dont judge the lens on a single performance parameter.

Perhaps you think to much in the hfq and the gt17 while there are much different versions and individual differnces. I do not need a testpattern to see my hfq is better it s like nigt and day. about green and blue try to understand this difficult way of thinking. I compared hfq green with gt17 red that gave a difference than I compared hfq green with hfq red that gave no difference. Tataaaa |

I had no problems focusing my outer corners, its all about flare magnets and stig, and getting it adjusted right. And i dont know why you have so much drift problems, it is usually setup related, to how the boards are operating, maybe you need to start all over with a standard Marquee that is working right, and get the mecanical setup nailed right before you do geometry and convergence.
Dont think its fair to judge a Marquee, for problems that might be related to you have been tampering with every board and even running different focus coils.
I see that your not interested in testing lenses, but only judging them from your reference point, and that i cant argue against, as i think we have very different references.
Anyway i thought this was a lens thread. But i dont think its polite leaving you all alone talking to yourself.
