The Camcorders themselves work pretty much the same.
The main difference is length of record times and ease of footage transfer and editing.
As to record times, DVD is the shortest. Next shortest is miniDV, in SP mode it is 1 hour and LP mode is 90min.
Hard Drive based is dependent on the size of the hard drive. Some hard drive and DVD camcorders also use memory cards that will give you additional time.These are known as hybrid camcorders.
All record formats can be found in both Standard Definition(SD) and High Def.(HD). SD being 720 x 480i (4:3) resolution and HD being up to 1920 x 1080p(16:9 or Widescreen) resolution.

It is hard to say without knowing which model Sanyo you have. Some use only up to 8gb SDHC cards while other only up to 4gb SDHC and other use MMC.

Could you post the Model number?

All camcorders can be edited with, with varying degrees of complexity of getting the footage on the computer.
The easiest footage transfer is with the Flash based camcorders. Simply insert the SD of SDHC card in the card reader and edit. Unless the footage has to be converted for a specific editing software there is no wait time for transfer. There is file compatability issues with some editing software.
miniDV based camcorders will need the footage captured in real time by Firewire (ieee1394) cable.
If you have 1 hour of footage it will take 1 hour to capture it on the computer before editing. Your computer will have to have a Firewire port before the camcorder can be connected. If it does not have one a card can be added to either a desktop computer or laptop/notebook to add a Firewire port.
For camcorders that only have A/V (Audio Video) out you can add a Dazzle from Pinnicle that connects to a USB port that allows video capture for editing.

This is what I could find:
The original 18-200mm VR, which was marked in gold on the lens ...AF-S NIKKOR 18-200mm 1:3.5-5.6 G ED. It uses Nikon's second-generation VR system later called VR-II. This lens is sometimes confused with the NEW Nikon 18-200 VR II lens which is the same as the original but features a zoom lock at 18mm., and is marked AF-S NIKKOR 18-200mm 1:3.5-5.6GII ED.
The AF-S feature is not supported by certain camera models.
The G-type lenses are fully compatible with the D100 and newer mode cameras.
The VR-feature will only work with Nikon's F5, F6, F100, N80, N75, N65, D100, D1 & D2-series or newer model cameras.

Try taking your lenses to your nearest BestBuy and give them a try on the Demo Model and see how they do.
