ill be more specific; I have vintage cameras, used film for years and now using a Nikon L-30. I need more training in digital use. vin
There are some differences, but not drastic differences. For one thing, the "ISO" setting is not a substitute or "upgrade" from the film speed designation, which used to be called "ASA". It is a completely different function, and it is used differently.
The modern lenses have some cool new features, such as image stabilization, and updated coatings, but fundamentally they are about the same. Some are very good, some maybe not so much.
Of course, you no longer have to load film and then process it, so there's that. You still have to care for your camera as a precision instrument, although with more electronic components than your film cameras.
Menus. You will find that digital cameras have quite extensive menus that are not always intuitive. Learning the menus will take some time and practice.
Lots more buttons, some of which are more useful than the others. Digital cameras have been engineered to be more user-friendly, so if you're having trouble warming up to them, you're probably trying too hard.
Unlike film cameras, there is a wider gulf between entry level and professional. Most people familiar with film cameras can just pick up a Pro film camera and get going. By contrast, the professional digital cameras need quite a lot of education, familiarization, and practice before anything becomes intuitive.
