I Googled it. There are a bunch of them that are not all that large.
It seems it took a couple of tries with Apollo 15 and 16 to get it right. A better explanation is here:

I saw the color analog video cameras online too.
None of those had built in battery packs.
None of the vintage cameras were “cam corders” with the ability to record on a cassette. Betamax and VHS cassettes had yet to be invented, and the 3/4” tape “cassette is enormous.
1” video tape was recorded on reels.
None of the 1970 cameras had the ability to record without a huge, TV sized recording machine nearby.
Where is the transmitter?
Where are the battery packs? Had to be huge.
Where is the recorder for the video tape?
How is all of this powered on the moon?
