Yes this is annoying.You could do what I do...seeings I am cheap when it comes to buying certain gadgets.(certain I say) Not sure what kind of wallet you use, but mine is a folding one in my back pocket. Take it out after a shot and hold it over the monitor. Mine folds 3 ways so acts like a shroud. Besides the fact I always have it with me, not buying a overpriced shroud saves me few extra dollars I can keep in it.
