By viewfinder focusing I mean the orientation on the certer of the viewfinder frame which tells when the spot is in focus.

I don't normally use glasses but to photograph with manual focus cameras I have to use glasses if I want my photos well focused. The thing is that I don't like using glasses for street photographs. I always feel the glasses are on my WAY specially when it get dirt.

So now I am shooting a roll without glasses and therefore I use the spot orientation on the viewfinder to focus instead of using my eyes. But since it will take a while until I finish the roll and see if it really works I would like to hear those who have tried and can say how good they are.

I am enjoy a lot to shoot in the streets without glasses.
