I am starting to get back into diving now that I live near lake superior and would like to purchase a set of neptune full face masks for my wife and I. I tried one when they first came out but didn't buy it because I couldn't look through the viewfinder of my SLR housing because of the shape of it. I am assuming that the shame of the modern neptunes hasn't changed much so my question would be; is there anything (either an attachment or a special type of housing) that will allow me to use my neptune with a slr. I am going to be buying a new camera and housing this year anyway.
