The big thing with Camcorders in particular is that it's highly dependent on which one you're referring to.
The ENG/Broadcast cameras with integrated lenses generally speaking cost quite a lot more for generally less image quality (Broadcast Standard not Cinema standard). However, this is because ENG/Broadcast cameras are intended to be used as complete camera systems (Shoulder Rig, Sound [XLR inputs w/phantom power], Video, EVF/Monitor, & High Storage Capacity) - thus they shoot more compressed files at common broadcast resolution (commonly 1080P@50mb/s data rate [at least in the states]). These are quite expensive to buy though and really don't offer you the same level of control over your image,they also have much smaller sensors (more difficult shallow DoF etc) as they are designed to be used for News gathering/Doc type applications (it's intended for a company camera or for an owner/operator using it constantly and not having time/assistance to pull focus). Great for Docs as image quality tends to take a step down to the conveniences of a full camera system, not so great as an all-rounder though.
Now, there are Camcorders with Interchangeable lenses that are perfectly fine, but you'll still (unless going PL mount) ending up using stills mounted lenses (Canon EF & MFT are most common [you can adapt Nikon to Both easily]). The Blackmagic cameras are classified as Camcorders (they do not take stills), they use Stills mounts though (except the B4 & PL mounted cameras). As well as the Canon Cinema EOS, & sony F series (FS7, FS100, FS700, F900, F55, F5 etc).
You don't have to buy a DSLR/Mirrorless stills camera for video, but they are damn versatile & cheap (an acceptable camera can be found for less than $1000USD), & offer very similar image quality. Lenses aren't as expensive/inconvenient as you think (I love lenses). They also do stills, which can be fun (this is /p/, take a look outside this thread).
