Panasonic Working on a 3D Lens Adapter for The LUMIX G Micro System

July 29th, 2010 · 3 Comments · Shooting in 3D

Panasonic is quite active on the 3D front lately, after the 3D lens camcorder adapter, the company also announced it is working on a digital interchangeable twin-lens, making it possible to shoot 3D with a normal 2D interchangeable lens system camera (micro four-thirds). Designed to be used with Panasonic’s LUMIX G Micro System the new 3D Lens adapter is expected to be available on the market, although nobody is yet talking about pricing or compatible camera models… even the specifications of the lens such as interaxial distance are still kept secret.

Now, you should know that an Asian Company called Loreo has been working on such 3D lens adapters for quite a long time now, they’ve had working solutions even for SLR cameras and now offer versions for Digital SLRs and even micro four-thirds. So Panasonic is actually not the first to offer such type product, but maybe their solution will be better although we’ll have to wait a bit more for additional details to surface, but it might turn out to be a good product and maybe even quite affordable.

And just one important clarification. Having this special 3D lens adapter attached on a normal digital camera means that the normal frame is cut into two halves and each half is used to store the left and the right eye image respectively. So lets say you are using a Panasonic DMC-G1 camera with this 3D lens adapter, since the camera has a resolution of 4000×3000 pixels (4:3 aspect) then if you take 3D picture you’ll have a single image where 2000×3000 pixels are used for the left eye and the other 2000×3000 pixels are used for the right eye visual information. If the images are not being squashed (and they probably won’t be) no stretching will be made and the 3D photo you’ll be getting will be with more height than width and that means black bars on the sides when viewing the image on a 3D monitor or 3D TV with 16:9 aspect ratio. The interaxial distance with this adapter is also quite small judging from the photos, so it will be more suitable for closer photography in 3D than actually taking photos of more distant objects.

Loreo 3D Lens in a Cap 9005 for Taking 3D Photos with DSLR Cameras

July 14th, 2010 · 6 Comments · Shooting in 3D

Loreo is an Asian company that has been on the market for quite some time, offering 3D lens in a cap type of adapters that allow you to take stereo 3D photos with a single camera. What these adapters do is to get the views for the left and right eye in a single frame which lets say better than average quality (depending also on the camera and the settings being used), but with a more affordable price and easier to use than actually buying a second camera and having to synchronize the picture taking etc. Of course the photo you’ll get with these adapters will be with half the horizontal resolution for the left and half for the right image (but not squashed!), thus getting much higher height of the 3D image then width and without cropping the image you will have huge black bars on the sides when viewing on a 16:10 or 16:9 aspect 3D monitor…

And the recently released Loreo 3D Lens in a Cap 9005 is designed for APS-C sensor format DSLR cameras and for 4:3 and Micro 4:3 format DSLR cameras. The lens has a focal length of 40mm and a stereo base of (interocular distance) of 90mm, making it ideal for portrait photography or shooting of close objects, but not too close or too distant ones. The 3D Lens in a Cap 9005 has a focus coupled Parallax Compensation system. So when the lens is focused on a subject at a given distance, the image pitch is automatically adjusted within the unit itself to suit the object distance. This works from 1.5m to infinity, however too distant objects will probably seem quite flat, because the parallax correction is not an all-powerful solution. The adjustment of the relative positions of the image pair can be viewed in the viewfinder, or with Live View in more recent DSLR cameras. The 9005 is also equipped with a pair of 58mm filter threads in the front, which can be used for attaching converters, filters and hoods.

LOREO 3D Lens in a Cap 9005 is available with a price of around $170-$180 USD and has different versions compatible with Canon, Olympus, Sony, Konica/Minolta, Panasonic, Nikon, Fuji APS-C sized and 4:3 and Micro 4:3 format DSLR cameras. And if you already own one of these 9005 Lens adapters you are more than welcome to share some photos you’ve taken with it, so that we can comment on the level of quality and the 3D effect that they produce.
