I tend to use old cameras, anything from the 1930's to early sixties, and I also shoot a lot of low light subjects, and as far as possible I avoid flash, so my exposures can very often be as low as 1/5 at 4 or 5.6, I focus as carefully as I can, but I get out of focus areas in my photos,but I work around the problems, as long as the main subject is reasonably sharp I don't worry, the main thing for me is the finished print, and I work around the shortcomings of these old lenses, I love the equipment I use, I get results I love, and other people seem to like them, and that is all that matters to me,
