Tried a search, sorry if a thread already exists on this subject.
Do you need to use HD lenses when filming with the HVX? Whats the difference between a standard lense and an HD lense? Do you need a different adapter for HD lenses?
 
Umm, the HVX-200 has a built-in (non-interchangeable) lens.

Are you referring to ad-on lenses like Wide angle and telephoto adapters?

skywalks, you need an adapter that fits the thread size on your fixed lens. Many camera shops, notably the Brooklyn shops, advertise "HD" adapters as a part of their packages, but that doesn't really mean anything. There is nothing "HD" about the adapter - it is just a piece of glass that distorts the image before it hits your lens.

If the adapter fits the thread size on the front of your lens (82mm for the HVX), then the adapter should do its job. Whether or not it is quality glass is a whole other issue....
 
A lens is a lens. The HD from an HD camera comes from the resolution that the camera records the image in, not from the lens itself. Some lenses of course look more filmic than others. 35mm lenses have great DOF and good clarity, which is why a lot of HVX users use adaptors to get 35mm lens images with their cameras.

Sorry, you couldn't be more wrong.

While the sensor and recording format have their own resolution, so does the lens. Specifically, lenses have the ability to resolve a certain number of lines per inch, and as long as the lens' resolving power exceeds that of the sensor, everybody is happy.

But when you put a cheap piece of glass (a filter or adapter) in front of a good lens / sensor, the cheap piece of glass will scatter the light and limit the quality of the recorded image -- it may be soft, have chromatic abberations, distortions, etc.

Do you honestly think you'll get the same image from a cheap $30 pair of binoculars that you get from a $1500 Zeiss of equal magnification?
 
I know that lenses have varying degrees of refinement, but I assumed, incorrectly I guess, that there wasn't a set definition of an 'HD' Lens for HD cameras. They were high quality lenses, just like in most other high end cameras.

Sorry, just trying to help (and maybe learn a thing or two along the way, haha).
 
You are correct that there is no clear definition of what a HD lens is. I wanted to correct the assertion that glass is glass, and that the sensor is the only thing that determines what the image looks like.

In fact, I would say that 99% of the filters and lens adapters that are advertised as "HD" in various camera packages are of inferior quality and not worth the cost of shipping.
