As I was playing around with my DIY-hoodloupe-on-roids an idea came across my mind:
If I take two 90 degree spy lenses (http://images.google.com/images?hl=et&lr=&um=1&sa=1&q=spy+lens&btnG=Otsi+pilte&aq=f&oq=) and screw them together I can ofset the image from camera LCD and if I fix an eyepiece to the other end I'll get a tiling hoodloupe-kind-of gadget also known as tilting viewfinder.
This could also work with an angle finder (from mid format cam) on the other end of a spy lens but I don't know if the image will be big enough and not mirrored to one or to the other side.

I have one spy lens laying aound somewhere, must test the concept.

What do you think?

If you twist between the two 90 degree angles, the visible image will rotate, which I doubt is the effect you are looking for.

Thank you so much for linking that. I've been envisioning something EXACTLY like that ever since I got my 5D2. That is PERFECT!

I had also thought of using a mirror to achieve different angles. I actually had purchased one for for use with a 35mm adapter on the HVX200 LCD. Beware, most mirrors have ghosting which makes focusing a torturous guessing game. To remedy, I had purchased one from an optics shop without any ghosting. However, as you can imagine, it flips the image - which ultimately is too difficult to use.

Which leads me to the main question about the flipbac. I'd assume it flips your image which will prove to be awful for real time video framing. And are they using an optical grade mirror?

If you twist between the two 90 degree angles, the visible image will rotate, which I doubt is the effect you are looking for.

So we got to test with one fixed 90deg spy scope or plain First Surface Mirror and an angle finder like Mamiya N for 645 (as it sees bigger picture than ordinary 35mm ones.
Does anyone have any experience with a rotating angle finder? how does the image get through it and will it too rotate when you rotate the finder? I assume those are prism based rather than FSM.

Somehow it works in real movie camera setup which is using half mirror and a prism.

Steev, sure any mirror mentioned must be optical first surface mirror as any other will give bad ghosting. But those spy angle scopes are fortunately using FSM at 90deg angle and are available from $18 at the bay but as Mike said a pair won´t work.

About image rotation: mirror at LCD right side (top view) flips left to right and an angle finder flips it?

Any thoughts?

The FLipBac is a great idea but it will be pain to use for normal shooting where I may review after 3 to 4 shots....the cover will need to be opened and close all the time so I will not be getting it.

Agreed. Once I saw that, I wasn't as excited anymore. They should make it removable somehow.
