How often do you get completely blown away by a simple purchase ?
No - me neither :-) Whilst this might be a simple accessory for your expensive new DSLR - Membrane are to be commended for producing a stunningly good 'simple accessory'.
Easy to fit and align accurately, absolutely no 'bubble battle', fits my 5D3 perfectly, and once fitted completely disappears! If there is any cost in terms of light transmission I am completely unaware of it. It has protected my camera in all sorts of challenging conditions; bright sunlight, wind and rain, sea spray ... and so far appears to be completely unmarked.
I KNOW it's just a little accessory - but isn't it just GREAT when something works SO well ? Wish I could give it ten out of five...
