EVF Technical question
 

Hi all,

Does anyone knows the pinout of the EVF connector on the XL-H1 body ?

thanks !

Hi

The CRT or the LCD ?

hi, sorry, what do you mean by CRT or LCD ?

Gilles must be thinking about a different camera - no LCD on the XL-H1.
Steve

Or Giles is talking about the fact that the H1 has an output for the LCD/Viewfinder and one for the CRT viewfinder add-on. I've always wanted the pinout information myself but apparently Canon keeps this well guarded.

i started investigating the EVF to determine its pinout so here is my current status in the attached pictures.
I still have to find out about the Sharp ic which seemd like some kind of LVDS receiver ?
also maybe th LCD panel itself - 5J001638W ?
if any one has some info ... please add your comments.
if i find anything furher, i will post.

Hi Yalon,
I have attached a document which seems to be a parts list and diagram of the b&w viewfinder. Don't know where I found it but maybe it is of some help to your work.

hi Wolfgang,

thanks for the schematics - it is for a CRT type EVF, i do not know it but it seems an old type. do you know if it is compatible with the XLH1 ? does it have the same connector (it does have 20 pins on its connector but i dont know its shape and compatibility)?
to my understanding of the schematics of the circuit board ( page 13 ) and the technology of the XLH1's EVF , it will not suit the signals coming from the XLH1... so i dont think i can make something that may helo us understand the XLH1 output...

Hi Yalon,

Is there any particular reason in looking into the viewfinder like this?

Are you trying to find a way to install a higher resolution screen or something along those lines?

I'd be VERY interested in that.

Michael,
exactly !

I wish you well!

I will keep my eye on this thread!

I dearly love my XL H1S ... only thing killing me about it is the LCD/Viewfinder. Wish it was up to par with what's out there these days.

Only hope I have left is whatever LCD/Viewfinder they come out with on the XL successor will also be compatible with the H1(s).

Now that I think about this, this should really help those with the original H1.

Focusing on the H1S is much easier than the original H1, due to the ability to set 2 levels of variable peaking in the viewfinder. I set mine to a really fine line that shows on the focused area. But a higher res viewfinder is always better!

I forgot that the original H1 only has a peaking option, and it was fairly thick.

wow
 

I'm always amazed at the technical skills some of members of this site have. Does anything go unanswered? (rhetorical)

I'd be interested to.....with an original XL-H1...the viewfinder was certainly one of the WEAKEST links of the camera.
Wow...to think of being able to replace that LCD viewfinder with a new...sharper version....OH LA LA !!

How is this coming along? Has there been any progress in finding a way to replace the LCD in the viewfinder?
