Well what i was planning on doing was using that nifty little 'lift up the viewfinder' function on my XL2 and sticking a mirror in between the two to flip it.

ill try to make a picture...

| | <---lcd screen part
|___| _____**
\ | |
mirror --> \ |_____ | <-- eye piece
**

u get the idea... im not sure if it would work but im thinking that it works the same way the view finder on an slr are works, and the same way they made their mini35 for Marla.

darn my picture didnt work... :(

Brian Valente April 13th, 2005 02:40 PM

phew - I thought it was just me!

Jon:
I have an XL1s and I'm not sure if the viewfinder mounting set up is the same or not, but if it is you can loosen the viewfinder, disconnect the cable and take the finder completely off. Then just put it on the opposite way so the finder is on the right of the camera. Your basically flipping it 180 so the image would then be upright.

It works fine on a tripod, but I'm not sure how well it would work for hand held.

Well the main difference between the XL2 view finder and the XL1s viewfinder is that the XL2's eye piece can flip up revealing an LCD screen. So what i was planning on doing was opening it up so the two pieces form a 90 degree angle and stick a mirror between the two to flip it. I think it works in theory, but ill have to get my hands on a micro35 first before i can clarify. I'll have to try the flipping the viewfinder around, but people seem to have different opinions as to how the image flips.

Can anyone give me a real answer (maybe with a picture) to show how the image flips? O and dont try an ASCII picture... it doesn't work...

The image will flip left to right and up and down. I didn't understand it at first either, but it's actually pretty simple. To correct for the 2 flips all you have to do is rotate the image 180 degrees. That is why the fliping an LCD screen works. It's the same for the XL. You just flip the viewfinder to right and it will be a 180 degree rotated image.

Explanation of the Rotation
 
I was just thinking how to explain the flips involved in these devices so here's an visual explanation of how the image is flipped through homemade mini 35/DOF type devices, for anyone who is interested...

Ketih are you saying the mini35 has this 180 issue as well?

Keith Kline April 13th, 2005 10:43 PM

No sorry I shouldn't have used the term "mini 35". The actual mini 35 uses prisms to correct the image back to normal. I was meaning for homemade devices or devices such as the micro35 and others. I'll fix the page.

Brian Valente April 13th, 2005 11:40 PM

That's what I thought - phew!

flipping...
 
here's a monitor that has a built-in feature for flipping the image:

Here's another one - at 1/2 that price:

That one would not work.. it only flips it horizontally... you would actually be better of using a non flip monitor and just physically flipping it. But the first one does both, I can only assume it does both at the same time.

Brian Valente April 14th, 2005 12:40 PM

crap - you are right! Here I was thinking I could get away for a cheaper price. I am pretty positive the TVOne version does both flips at the same time - Larry said they used this in The Ancients and didn't have any complaints.

Kevin Richard April 14th, 2005 01:20 PM

you could still get the cheap one and just turn it upside down... that would achieve the same effect.
