In other words you have a few very usable lenses should you decide to shoot a larger format negative than you currently do. The Anticomar should also cover 4x5, if you want it to. All you have to do now is start buying more equipment...larger equipment. It is a slippery slope, but the valley you fall into isn't an unpleasant place to be, honest. You just have to get used to thinking about gear, moving gear around your house, loading your car with gear, having the choices overwhelm you when you go out to shoot, talking about cameras with other denizens of the valley, lusting after that old, moldy 8 x 10 you saw in the basement of a distant relative, examining odd lenses and wondering what type of image they might make on a camera, designing lens boards, new backs, new film holders for whatever project is working away in your feverish little mind at any given time... No, it's not a bad place at all. You just have to be a little crazy, is all.
Come on in. The water is fine.
