What are the application scenarios of macro lens?

Macro lens mainly takes macro lens. Traditionally, it takes portraits or still lifes at the same time. Nowadays, wide-angle macro-shooting is also popular, which can shoot scenery at the same time, but it is mainly macro-shooting.

I don't know your specific situation. Can't you use a macro ring or an extra macro mirror? These two are much cheaper than macro lenses. If you can only use a macro lens, it is recommended to accept a second-hand lens and then use it again. It's just a little troublesome, and you won't lose anything, and sometimes you can even make some money.

Also, you can directly find a photography studio to scan the film for you. They have a special film scanner.
