I discovered a interesting thing on eBay,It named display mirror,We can catch
multiple angle after installing on digital camera,what a intelligent
excogitation.
here is introduction
I hate to say it, but that actually looks interesting. It's a swiveling mirror that mounts to a 2 or 2.5" LCD for cameras that don't have an articulated screen. The link above is to Gizmodo.
That is really a good idea. I tried to make something like that mounted on the tripd socket but this is much classier. They don't say how to order it.
I ordered it on eBay.It costs about $10~$20.You will be find it that typeing in the keyword ''LCD Display Mirror'' on eBay.
