35mm DOF adapter - Static vs Vibrating

Static- Advantatages
Fixed static ground glass,
no motor mechanism,
no battery module needed
simple operation hence much Cheaper
Can shoot at higher shutter speeds.
Longer lasting, no parts to breakdown
Can be used in low light conditions when used with a f1.8 lens (Also depending on the camcorder low light capabilities).

Static - Disadvantages
Ground glass has to be spotlessly clean as dust will show up in footage
Limited lenses selection. F-stop maximum 2.8 lenses (usually in the range of f1.2-f2.8 lenses only)
Recommended low cost lenses Canon 50mm f1.8 (USD $90) Nikon 50mm f1.8 (USD $125) and Canon/Nikon 85mm f1.8 ($350 - $500)
Any lenses above 2.8 like the cheaper DSLR kit lens Canon 18-55mm f4.5-f5.6 cannot be used as dark grain from the ground glass will show up in footage.
Rough out of focus background/foreground (bokeh) like looking througn frosted glass). Will look acceptable when scaled down to SD resolution and
less noticeable when shooting in SD format.
Main usage is for web videos and home/vacation or hobby videos.

Vibrating - Advantages
All lenses can be used up to f22. Cheap DSLR zooms will work well too.
Vibration will cause grain and fine dust to be invisible due to motion blur effect.
Can be used in low light conditions when used with most lenses (Also depending on the camcorder low light capabilities).
Will give a good quality picture in HD resolution.
Good quality images can be used for professional work.

Vibrating - Disadvantages
Much more expensive, usually costing up to 30% to 40% more than static adapters.
Max shutter speed is around the 1/180 to 1/200. Moving ground glass grain will be noticeable at higher shutter speeds above 1/200.
Battery module makes the adapter more cumbersome and battery power must be switched on when recording.
Forgetting to switch on the vibrating mechanism will render the shot useless as footage will show grain and dust like a static adapter,
so an LED indicator on the adapter is a must. The gt35pro Vibrating adapter series provides this feature.
LED on the power module is not good enough as you sometimes don't look at the battery module box.

Conclusion -
Unless you are shooting hobby/enthusiast videos or scaled down videos meant for web (youtube or vimeo) and on a budget, You can get the Static version.
For movie production or professional work, the vibrating version is a must.
