"You cannot play with my video camera."
Translation:Nie możesz bawić się moją kamerą.
The use of "z" would imply that you're playing "(together) with a person" and not with an object.
For example, playing "with" a camera or with toys would be:
- Bawię się kamerą
- Bawię się zabawkami
If you were playing together with your friend or your sister, that would be:
- Bawię się z moim przyjacielem
- Bawię się z moją siostrą
That said, you can't add "z" if you're playing with an object. In the second case, theoretically you could remove the "z", but then if you'd say something like: "Bawię się moją siostrą", it would get a different meaning and sound very very wrong like... "I'm toying with my sister" where the sister would be the "object" you're toying with and not the person you're playing (together) with.
I hope this helps :)
Good question. Well, "kamera" in Polish by default is a device to record video. English "camera" can easily mean a device to take photos, which is "aparat fotograficzny" (often just 'aparat').
"Video game"... well, we mostly talk about "gra komputerowa" = "computer game". "gra wideo" is probably okay, but I just don't hear that very often. Also simple 'gra' nowadays will often be used, if the context makes it probable that we're talking about a video game.
"video meaning a CD"... VCDs are really obsolete, you can't really buy them nowadays I think... even if you could, why would you do it? :D
There are at least three possible constructions with grać:
Grać w [accustive/locative]: This has to be either an official game (grać w tenisa, grać w szachy) or a location (grać w orkiestrze, grać w Warszawie).
Grać z [instrumetal]: This most commonly refers to participants/opponents of a game (grać z Polską, grać z tatą).
Grać [instrumental]: This is used either for the equipment something is played with (grać rakietką i piłką = play with a racket and a ball, grać palcami na pianinie, grać białymi bierkami szachowymi = play with the white chess pieces) or with for intangible concepts (grać kartą ofiary = play the victim card).
