hdl10 trade for gt17

I had swapped around a bunch of lenses, going from the universal to the best for my screen size, a set of GT26's. I did not see any real differance in the video image, there probably was, but I would have to have used a more scientific method, other then just watching some DVD's. Well at least I know I have the best.

hmmm, that's wierd, a friend of mine locally switched from HD10L's to starigth HD10" on his 96" wide screen and the improvment in corner focus was substantial. Gary you need to find out which HD10 ou have, the suffix is differnt on them.
keep in mind a set of straight HD10's are worth about $250., HD10L's about $100. , and HD10GT17's sell for $700. set .

Really? There is that big a price difference for what seems to be variations of the same thing? I suppose the HD10-GT17's are so popular because they're ideal for the most typical screen size.

There are alot of varibles involved, screen size, PJ throw, curved screen, flat screen... What I'm saying is you do not know what you will get in the end. At that the better lens should be better.

On mine I ended up shimming the lenses to get proper flapping adjustment, improved the edge focus on one side by quite a bit.

Does anyone know what goes into these better lenses? Or what makes them better then the universal lens?

I have tried some different lenses on my 9500LC.
It throws a picture 88" wide on a flat screen.

Started of with HD10L. Bad corner focus. Obviously the wrong choice.
Went GT17. Better corner focus, but still not good enough.
Changed to HD10F. Awsome corner focus. The HD10F is the perfect choice in my setup.

oh for sure,like alan guessed the GT17 is just most popular because it fits perfectly on the average 91" wide HT flat screen (actually rated for 91" to 114" wide on 9500 by VDC). If you have a curved job or some other rare screen then it might turn into a long experiment as to what's best for you. What i'm wondering now is what the hell is a HD10F? Never even heard of it before.

What I know:

10L- good for up to 72" wide. No more than that. Trust me. I found out the hard way. 4 trips out of town no less. I'm an idiot!

10F Sony's answer to the GT lenses. Found only on G90s and 1292s.

I will do some SERIOUS playing with HD 120, HD 10, GT 17, GT 26 and HD 300 on a 96" wide screen over Xmas when I have time. I don't think you'll see the difference between 10 and 12 lines of resolution, I think the tube is the limiting factor. But I could be wrong, thus the experimentation.

HD10F is pure optical magic!

Said in the matter by Mad Mr H:
"Sony 1292 and G90 use a HD10F - this is sometimes thought to be a HFQ900 - this is NOT confirmed.

However Barco call the Lens a HFQ900

I am under the understanding that these are "based" around an HD10E lens BUT have better edge focus and so "might" be hand picked with the tightest tolerance, or have a "special" outer focus system. "

Curt, When you say
"10F Sony's answer to the GT lenses. Found only on G90s and 1292s."

Are you reffering to GT17 or GT26? (Or both at the same time?)

What I found with the HD10F lenses is that they have a huge focus range compared to GT17, but still very precise edge focus. A pair of GT26 is on it's way here (for an other install). If I find the time, I will compare them with the HD10F next week.

When I first got my 9500, it had the HD-10L and the focus was terrible on my 52X92 screen. I tried the HD-10 and the focus is so much better... I have not tried the HD-10GT17's yet.

Where on the lens do you look to see what model you have? I have three Ampro 4000G's. Only 2 of the 9 leses have a HD10 sticker on them.

hello mr lyckman

do you want your hd10gt26 back now?

Wise Words

From a Mad Man .

All I know is that my 10Fs kick the snot out of the 10s and 10Ls I've tried before

I'd be curious to see how a HD10F compares to my HFQ900's

I have 10F's X 6 so we shall soon see.

how much would the hd-10gt26's be worth and how do they compare focus wise to
the other lenses mentioned? also how would these compare to the hfq900?

Straight HD10s are pretty amazing lenses all in all. I would start there and try them out - as they are cheap as chips. I have a set here I could lend you - although you would need to pay postage (i'm in Australia!)

GT26's are for larger screens than the other lens's.

In comparing the HD10F's (early 1292's and late G90's). HD10GT17's, and HFQ900's on a 96" wide screen, what we found was that:
* There is a difference between early and late HD10F and the late one have better overall focus especially the corners.
* The early HD10F's are about the same as the HD10GT17's with a very slight improvement in corner focus but not enough to justify changing to the early HD10F's.
* The HFQ900 lens's are the best of the batch both in corner and overall focus.

Conclusions, if you are running HD10GT17 lens's unless you are going to change to late HD10F's (from a G90) or HFQ900's don't bother to change to early HD10F's from a 1292.

BTW boomtruckman2003 I have someone who might be interested in a set of HD10GT26 lens's as he is running a very large screen and currently has HD10GT17 lens which are pristine and new looking. So if you are running a screen that is less than 102" wide you might want to consider these. He is wanting to trade.

Terry

Terry I have a set of GT26's in nearly mint condition that I would trade for the GT17's. Glass is perfect with no cleaning marks. I would expect the same from the GT17's.

Tom.W

thanks for the info terry, i need to keep the gt26 lenses as i will be
going to a 140" x 75" screen in the next few months, would hfq900
focus well on a screen this size? i currently use a 7' wide screen,
1209s with the gt26's but it doesn't focus near as well as the 1351lc
i was using before, it should focus better i guess on the bigger screen,
it will be a few more months before i finish building the 20' x 24' room
before i can find out

Tom,
I have a less than 500 hr Runco 1101 that these lens's would be coming off. They have no stickers on them but I am sure they are the Barco HD120's which are near identical to the HD10 GT17's in focus range and being 2001 built maybe a little better. These lens's look like new.
So here is the deal, I have someone looking at the 1101 to purchase and if he does, he will want HD10 GT26's.
I'll let you know if the "deal" goes through.

Terry

Just so that you know, the 140" wide screen that you are going with is IMO way to large for your PJ. For best picture you should try and stay under 102" wide or less. Personally I would go 96" x 54" for best picture.
I've never tried to focus that large on the HFQ900's.
On your 7' (84" wide) wide screen the you will not be able to get any kind of corner or edge focus with the GT26's as they are for much larger screens.

Terry

hi terry, i agree it's probably too big for the pj but i've already
got the screen so i've got to at least try it, i can always go
back to a smaller screen, what about stacking 2 1209s's?
or 2 1351lc's?
would a 140" screen still be too wide for 2 pj's?
or do you think i would be happier with a smaller screen
even with stacking?
thanks for your opinions!

I just got a set of HD10's with no suffix so what was the concensis now? This thread gives no real answer beside the HD10L's suck and the HFQ900's are the best. I would specificly like to know for a blend set up, for now i will be doing 8inc air coupled and have HD144's but want to upgrade at a later date and am acquiring parts now. I have one set of HD10's and a set of HD10GT's comming soon. can they be mixed or would it best to get another set of HD10's or should I try to sell thses HD10's and look for another set of HD10GT17's the screen for now is 12 feet but plane to go 13-14 feet wide.

Athanasios

Are you going to be upgrading to 9" tubes or are you going to be converting your 8" tubes to LC. If staying with 8" the GT17" lenses will work very well. I used them when I had my 8500LC and I was able to get perfect focus corner to corner on an 86" wide screen.

I was not a fan of the regular HD10 lenses, they cause a very minor reflection on mixed content scenes. See http://www.curtpalme.com/forum/viewt...ght=reflection

I was using HD10 lenses when I had this problem and the problem went away with the GT17 lenses.

Chris.

Not sure what I plan for now. I have one 9500LC that came with HD10L's, not useing those, And I just got a set of 8 inch LC tubes. I was going to run my blend for now with the HD144's AC and eventualy move to an LC unit now if I decide to use the housings from the 9 inch on the 8 inch tubes or look for a nother set of bar 9 inch for the futurs is still up in the air. I have a set of HD10GT17's comming and I now have this set of HD10's.

And now with the VDC bellow fiasco(not selling only Bellows) I might just sell everything and keep the AC marquees so not to mess with paying 1000 a tube for overhauls. VDC is screwing the LC marquee owners.

Athanasios

It would be quite easy to convert the marquee to accept Barco or Sony LC housings. You could then avoid the issues with the Marquee bellows.

Chris.

I think VDC is the only place to get LC Bellows for all PJ's, isnt it?
