1. The importance of a 35mm Adapter is not DOF, but FOV. Without a 35mm Adapter on small sensors, the FOV is quite limiting. I wouldn't tell anyone they absolutely had to use a 35mm Adapter. I would absolutely recommend a Wide Angle adapter for your camera, however, to gain a greater FOV out of your fixed lens system.
This is sort of a strange statement... given how 'Letus' a popular provider of adapters 'sells' their product...
A portion of one...: (please note the phrase, DOF ... is what this site is all about...)
--------------------------------
DOF / depth of field (or depth of focus) is what this site is all about. Depth of field (DOF) is the distance in front of and beyond a subject that appears to be in focus. Obtaining different depths of field can create dramatic, film-like effects that will take your productions to the next level.
Rather than trying to describe the varying depths of field between different camera types, let's explain it with a simplified chart. The image below shows the difference between a 35mm film camera, a 1/3" sensor professional camera, and a typical 1/4" sensor consumer grade camera. A sample of each is displayed with their approximate "in focus" ranges and how the different focal planes may appear.
--------------------------------
As for an example, the literature from Panasonic on the HMC 150, indicates that the equivalent 'wide angle' of the lens is 28 mm relative to 35mm. So, yeah, for some sort of adapter, one can get effectively 'shorter' lenses.
Also, perhaps because I've not paid much attention to the adapter fora, are such lenses as Cooks, Arris, Panavision, et al. lenses the most likely lense to be used with such adapters... or are they mostly still camera lenses from Nikon and Canon?
