I recently bought this LCD viewfinder from amazon: http://www.amazon.co.uk/Magnification-LCD-Foldable-Viewfinder-Magnifier/dp/B004TDXMHM/ref=pd_cp_ce_0. I’ve done a little video review of it.
Overall, it’s nice enough, not phenomenal quality, but for the money it’s not too bad. It doesn’t use a magnet, which means that personally I prefer it to my LCDVF now, although the plastic and build quality isn’t as nice. For the money, though, it’s a nice little bit of kit, and the ability to flip it up makes a great positive as well. Have a watch of the video and let me know what you think:
