Most word endings used for 'collectors of something' are in Greek. (e.g. 'phile' for 'lover' or 'ologist' for 'studier') but 'camera' is derived from Latin, so it's not that easy to create a suitable new word. (A few words, such as 'television' mix Greek and Latin but they're fairly unusual).
You could possibly use 'amare', meaning 'to love', from Latin to get an all-Latin word, such as 'amacamera' but it might be better to translate 'camera' to (modern) Greek first and then add 'phile'. As it happens, modern Greek uses the same Latin word for 'camera' as we do but with a minor spelling difference. It's 'κάμερα' or, in our alphabet, 'kámera'.
So I'll opt for 'kamerophile' as the best word to meet your needs. (It seems to run off one's tongue best if the stress is put on the second syllable, with that syllable pronounced like the Scottish town of Ayr. i.e. "kam-AYR-ophile")
How does that suit you?
