SGpro FAQ

Q: What is the purpose of the SGpro 35mm Image Converter?

A: The SGpro allows you to use 35mm SLR lenses on your DV Camcorder. This gives you the same Depth of Field and Field of View as with a film camera, which gives a nice cinematic film look to your footage.

Q: What camcorders work with the SGpro?

A: Currently, the SGpro works with all 72mm lens camcorders, such as the DVX100, FX-1/Z1 and the Canon XL series, also works with all smaller lens camcorders via step rings and the HVX200 (an 82mm cam, reqiures step ring).

Q:What lenses can I use with the SGpro?

A:We currently offer the following lens mounts:

Canon FD
Canon EOS/EF
M42
Contax
Leica R
Leica M39 Screwmount
Minolta MD
Nikon
Olympus OM
Pentax K
PL mount
OCT19

Q:Can I use more then one type of mount?

A:The SGpro uses an interchangeable mount system, so you can change from 1 mount to another in just a few seconds. This is useful if you have a mix of lenses, for example, Nikon and Canon FD.

Q:I've heard the image is upside down, is this true?

A:Yes that is correct. The SGpro produces an image that is rotated 180 degrees (flipped horizontally and vertically). The image will need to be rotated back 180 degrees in post production. It is recommended to use a monitor mounted upside down while shooting.

Q:Does the SGpro loose light?

A:Yes, all 35mm adapters/converters loose light, some more then others. The SGpro has been reported to loose only 1 stop of light, which is amazing. This is without the 35mm lens attached. The 35mm lens will loose some additional light, this is determined by the lenses 'F' rating.

Q:What Lenses are a good choice for the SGpro?

A:Lens choice comes down to both practical use and personal preference. Some lenses allow more control then others. Some users perfer 1 make over another.

Basic rule is to use a lens with the lowest 'F' rating possible. The lower the F rating the more light passes through the lens, which is a good thing. All lenses have an 'F' rating, shown on the front of the lens. For example, a commen 'F' rating on a 50mm lens is 'F1.4'. An 'F1.2' lens is better as it lets in more light, however they are more expensive.

What about focal length? For your first, a 50mm lens should be choosen. After this, a 28mm lens is a great choice, and gives a wider FOV. A nice 28mm F2.8 lens can be picked up for a good price. Also, an 80mm lens will be good for close ups.
