From a VX filmer's stand point, do think of these first;
- Consider you need to capture tapes (unless you decide to go down the tapeless device route). That means having a FireWire port (or a Mac that has IIRC, Thunderbolt that you can ise a FireWire to Thunderbolt connector). You can fit one easily to a PCI slot if you're on PC.
- Glitches can and will happen, so do prepare for those being a thing. Heads can die on you and are costly to fix.
- Don't be put off by VX2/21's (21s were the newest out of the two). Although they do not have the same look and sound of VX1's, they're still good cameras. You still get the VX 'look'. You could consider the Canon equivalents (XM1 or XM2) but using an XM1 myself borrowed from a friend once I can't say I was a fan and probably for the same price or for a bit more, you could get a decent 2 or 21 if VX1s are relatively costly.
- MiniDV tapes are becoming harder to find and thus, more expensive. I seem to see a lot of Instagram resellers having stockpiles, so maybe not too bad? I haven't asked them for prices since going down the tapeless device roure, so they could be $$$$.
- They are older cameras, meaning they can go wrong (same point with what I was saying about the heads) If you're in the US I believe Kerry still fixes them and if you're in Europe you got vx_doc on Insta, so you're not hard done by for repairs to be honest.
But uh yeah, depending on how commited you are don't let those points put you off. I bet other VX filmers might scowl at that, but it's something to prepare for if you are really considering the 'SD' tip.
