How does one focus for landscape photos in very dark conditions?
I have a Pentax K-r with the kit DA L 18-55 and a prime DA 35. As far as I'm concerned, they are good lenses indeed. However, there's one little annoyance: they doesn't have a focusing scale!
I like doing night time long exposure photography. Obviously, with the scene in the viewfinder almost pitch black, there's almost no way the AF system or my eyes can get a good focus on the subject. So, I guess it would be nice to have focusing scale in the lens isn't it? Do anyone know the focusing scale on those (and maybe more) "scale-less" lens?
