GH2 gets WIDE from 6mm to 3.5mm This is a movie shot with three lenses, from 6mm to 3.5mm, in crop mode 1:1, which is 15mm to 9mm for micro 4/3 sensor (24X36 : 31mm to 18mm). 1st part with the Pentax 6mm (MODIFIED lens, more info: http://vimeo.com/20766631), some shot with polaroid variable ND filter. Second part, same lens but with a Pixco 0.45X lens converter, found for 16€ on ebay, it's 40.5mm screw mount filter size lens is perfect for the Pentax. The third part is shot with a new lens I've found on Ebay for 46€, a C-mount Rainbow 3.5mm 1.6, perfect for the crop function ! It's very wide, little fish eye effect, but I have a little focus problem with my copy, so I have to closed the aperture, but not too much because it seems I have problem of intern dirts, that can be viewed in more closed apertures. I like this 3.5mm Rainbow C-mount lens, it's fun and very wide. I hope you'll enjoy the shots.

This is the forth lens test reel showing the use of a Kowa 3.5mm f/2.4 HR megapixel wide angle rectilinear C-mount lens LM3NC1M with with Tiffen ND0.9 density on some shots using 1920x1440 resolution cropped to 1920x817 then letter-boxed into 1920x1080. You can also see demo reels #A2 #B1, and #C1 on my video page for anamorphic (Scope) and spherical (flat) shooting examples also for 2.35:1 wide screen shooting modes at 1828x1556 and 2592x1104 pixels resolution. I am testing various lenses for use in film-making projects using the Super8 format Digital Cinema Camera called the KineRAW-S8p (tm) made in Beijing China. This camera records fully uncompressed at various cinema aspect ratios and resolutions, this video was shot at 1920x1440x12bit@24.000fps 99.5MB/s to high speed SSD in the camera (data rate varies with the resolution being recorded). 1920x1440 is the standard TV 4:3 aspect ratio a bit larger than academy 2K 35mm movie film scanner pixel resolution of the Kodak Cineon (tm) film scanner (1828x1332) pixel resolution used for making Digital Intermediate (DI) for movies like what you may have seen in movie theaters. The KineRAW-S8p (tm) prototype camera has two drive slots and can dump the SSD used for frame recording to a notebook HDD in the camera (for backup or to erase and re-use the SSD) so my setup was 60GB SSD and 500GB HDD for these lens test reels. The camera can take C mount, CS mount, and D mount (regular 8mm) lenses. The image area varies with the resolution mode, some modes are about Super8 size so C mount lenses made for Super8 cameras may be used. the frames were processed in a free program called DANCINEC.EXE (tm) that is on my web site for download and "beta-testing". The workflow was DNG to TIF, the TIF were edited in my 'freeish' DI/NLE/CC/MIX software DANCAD87.EXE (tm) and output as BMP frame set letterboxed 1920x1080, that was converted into a MPEG4v2 6000kbps AVI in VirtualDub (tm) and uploaded here. There is no stereo sound on this reel (see reel C1 for an example of sync sound shot with the KineRAW-S8p (tm)), but the camera can record sync sound 48000 samples/second stereo, and has an auto-slate beep, slate information stored in each DNG frame's meta-data, and Date+TOD plus SMPTE TIME CODE for sync with an external sound recorder or SMPTE slate etc. The camera used is a pre-production prototype that I am testing for use with my free de-Bayer software I am developing for use with CinemaDNG recording uncompressed Digital Cinema Cameras like Aaton (tm), Acam dII (tm), SI-2K (tm), Kinor-2K (tm), digital Bolex (tm), Blackmagic Design Cinema Camera (tm), KineRAW-S35 (tm) (in second prototype in house testing now in China), planed KineRAW-S16 (tm), planed KineRAW-S8 (tm) (production model of the camera being tested here) and for use in my own filmmaking projects. The KineRAW-S8 (tm) production cameras may be somewhat different from this test camera and I may be able to improve the results that my de-Bayer program produces as I am still experimenting with various filter adjustments and code developments. This was processed mostly with v0.06. If you have any thoughts or questions about the de-Bayer processing you can email me through the address at my program's web site. You can google Kinefinity (tm)'s KineRAW (tm) cameras to read more about their camera development, I am not involved in sales of the cameras, just trying to work with them to support their and other companies DNG recording Digital Cinema Cameras. You can google DANCAD3D (tm) to find my web site. If you see some 'ghost' marks on moving image parts that seems to be a compression artifact (?) from the making of a compressed video to upload here rather than in the original camera data. I will probably have some uncompressed frames from this video to email back if you are interested in seeing how the images would look on a 35mm film transfer or to be used as a source for Blu-ray or DCP for projection in a digital movie theater. The Camera shots 100% uncompressed, so there are can be some losses or banding and noise differences in the double compressed version you are viewing here. Its best to view this video from 3x the image width so if you have a 36" monitor you should be about 9 to 12 feet away from the monitor to get the same angle of view that you would have in an art-house movie theater maybe. The playback should be 1:1 pixel so that requires a monitor that is 1920x1080 or larger and don't use fit to screen as that will re-size the image and introduce aliasing and re-size artifacts. If your monitor is smaller than 1920x1080 set the player to 50% or half size image so you see it 960x540 so the resize is an exact half size, you may see some added aliasing that way but the blur from odd ratio resize should be avoided, maybe. If you would like to see some uncompressed frames used to make these videos you can email me directly or message me through Vimeo with your email to send the frames to in your message. Put "unco
