Re: lens front attachments ...

I'm beta testing an SGPro with the HVX200. SD looks terrific; very film-like depth of field (or lack thereof). HD is currently a little soft. To my knowledge this is an issue specific to the HVX200; the manufacturer has been very responsive & is making some adjustments to the SGPro setup & optics that should resolve this. They are also coming out with a follow-focus in late August.

One note - a lot of these units (including the SGPro) flip the image 180 degrees. This is by design (I suspect to preserve image quality & keep the cost down). This is very easy to "fix" in post by flipping the image. However... in the field you'll need a montor capable of flipping 180... otherwise you'll be trying to shoot upsidedown & backwards... not an easy task....

Buy the ticket, take the ride.
