    Whilst shooting at an airshow last weekend some old guy in front of me had a strange looking camera.

    It looked like something out of Jules verne :wink: Very nice, but the strangest thing about it was the fact that it had two lenses :shock:

    I've sort of heard about Double Lens Reflex cameras but how do they work? Do they produce a double frame image or do both lenses produce one photo?

    They must have some advantages or nobody would have bothered making them, but then if they had why aren't any around today?

    A TLR or Twin lens reflex camera has two lenses. One for viewing and one for the actual exposure. The idea is basically the same as an SLR except that the mirror does not have to flip out of the way.

    That's about the extent of my knowledge on the subject.

    Hmmm. I can't see the sense in that. You'd still get paralax error and so you might as well use a separate viewfinder like more conventional point and shoots. :?

    The paralax is really a non-issue. The better TLR's will have a guide for paralax which is not really noticeable at wider angles. That or you can move the camera up an inch to compensate.

    most definately not a stupid idea. That would be like calling rangefinders stupid (they have paralax too). TLR's have their place.

    When the mirror moves you get vibrations. Without a mirror you don't get the vibrations. I think that was the only reason for them. Some cameras allow you to lock the mirror up. But that has the downside of turning the viewfinder black. That can be a problem from time to time. You may move the camera slightly by turning the knob. Do any modern slr's allow you to lock the mirror up? Probably just the high-end ones?
