320细节题。根据“…The Olympic BY model weighs only 320 grams…”可知正确答案。

There are a lot of good cameras available at the moment. Most of these are made in Japan. But there are also good quality models from Germany and the USA. We have investigated an arrangement of models to see which has the best value for money. After a number of different tests and interviews with people who are familiar with different cameras being accessed, our researchers recommend the Olympic BY model as the best auto-focus camera available at the moment. It costs 200 dollars although you may well want to spend more, perhaps as much as another 200 dollars on buying additional and other equipment It is a good Japanese camera easy to use, equivalent German models tend to be heavier and slightly less easy to use, while the American versions are considerably more expensive. The Olympic BY model weighs only 320 grams, which is quite a bit less than other cameras of the similar type. Indeed, one of the other models we looked at weighs almost twice as much. Similarly, it’s smaller than most of its competitors, thus fitting easily into a pocket or handbag. All the people we interviewed expressed almost total satisfaction with it. The only problem was slight awkwardness in loading the film.
