I have too little rep (188) to create own tags. Is there a reason why there is no tag for "analgoue"? The standard is probably digital these days so I think it could be good to have one for analogue which is rarer.
In photography, the term of art for that is film, which of course we have a tag for: film.
First, see British English vs. American English in tags — we've standardized on American English spelling for tags for consistency (but, we leave whatever variant the writer uses in titles, questions, and answers). So, it would be analog.
However, "analog camera" is a retronym. Until digital cameras came along, there was no word for such a thing — they were just cameras. So, while analog (or "analogue") might be an okay label, I don't think it's a universal one.
This is compounded by the fact that the sensors used in digital cameras are analog devices — it just happens that we digitize their output for our convenience. In a slightly-alternate world, we might have that output instead written to tape or some mini-laserdisc. Of course, we aren't in that alternate world, but, still, analog isn't necessarily the opposite of "digital camera".
Plus, there are many things other than camera recording medium which are "analog" — some light meters, for example. A tag grouping all of those things isn't necessarily particularly useful.
All that said, I think what you're looking for is film-cameras.
