Redrock Micro has created a Canon EF to Micro Four Thirds lens adapter which adds the electronics required to control the aperture on the mounted EOS lenses - 9V battery and a touch-panel allows the adapter to specify the lens aperture in 1/3EV steps. The adapter (LiveLens MFT) costs $442.50 and is available directly from the manufacturer's website.
The Redrock Micro LiveLens, Active Lens Mount for Canon EF Lenses currently sells for $495 on amazon, while the manufacturer has an introductory pricing at $442.50.
Redrock Micro's LiveLens MFT provides the required power and electronics to control Canon EF lenses when attached to a micro four-thirds camera body. With the LiveLens MFT's control touchpad, the EF lens' aperture can be open and closed in increments as small as 1/3 stop. The LiveLens MFT works with virtually every EF lens available today, including variable aperture zoom lenses, prime lenses, consumer-level lenses, professional L-series lenses and most third party EF-compatible lenses. A marvel of advanced design, the LiveLens MFT is incredibly compact and weighs less than 6oz. (via dpreview)
Mosaic Engineering showed a filter that it said to remove lots of annoying issues with the Canon 5D MKII: The filter can be easily removed for standard photography and requires no modification of your hardware (which means no voiding of warranties).
* Optically corrects most aliasing and moiré artifacts in 5D Mark II HD video.
* No reduction of 5D Mark II 1080p video resolution for most lenses.
* True optical correction before video image capture – no postproduction software filters or processing.
* Easily installed or removed in less than 20 seconds.
* 5Dmk2 H.264 codec compresses with better quality with the VAF-5D2, because false, high-frequency, aliased image components are eliminated before compression.
Moire, caused by the downscaling from the image information from the huge 21MP chip affects by line skipping, manifests in issues on fine fabrics, hair, bricks, water, lines. This filter removes all that, and more.
PLUSSES: Removes most of the visible moire, only the most stubborn stuff it cannot remove. Big success on aliasing. A massive improvement on image quality for video compared to shooting without it.
NEGATIVES; Not good with wide angle lenses. Some lenses work better with it than others. Not parfocal. Slight image softening. Close up focus changed. Be careful with old Nikon lenses with the bit of metal that sticks out. It can damage your filter and if you are not careful like me…your camera too! (Update: this issues seem to be fixed in the production version.)
[Update 2012-03-11] I was asked if this filter can be used on the Canon EOS 5DMKIII and I actually think it can, while it remains to be tested if it actually makes sense to use it. The Canon 5D MK3 still has moire: its processor doesn’t line skip anymore but it still has to process the image down from 22.3 MP to 1920×1080 which may create some minor moire or aliasing issues.
This is an information from our Partner, 5uper.net:
In Autumn of 2011 the Festival Coded Cultures takes place for the 4th time, this year focusing on the topic "City as Interface". Ever since the foundation of the Festival in 2004 lay the general emphasis on creative practices of cultural development on the intersections of art, technology, science and design. It is our concern to decode de- velopments, concepts and projects in those “coded” structures of digital and (new) media production, which won’t open up easily to broader audiences. Over the years the alignment of Coded Cultures and its variations were orientated internation- ally with the focus on eastern Europe in 2004, Brasil in the following years and Japan in 2009. This year, Coded Cultures involves mainly participants from Europe with prominent attendees such as transmediale from Berlin, Media Lab Prado from Madrid, Amber Festival from Istanbul and the Enter Festival from Prague.
Coded Cultures 2011 presents itself on many different locations in Vienna, with the main focus on the Donaukanal (Danube Channel) and the surrounding Viennese city districts.
From 21st to 25th of September focus days will be held, which mainly will take place at the Viennese Danube Channel, the 2nd district of Vienna, Museums Quarter Vienna, the Badeschiff and the Odeon Theatre. From the 26th of September to the 2nd of Octo- ber workshops, presentations and artist-talks are taking place. Partners are Transmediale Berlin, Media Lab Prado Madrid, Enter Festival Prag and Amber Festival Istanbul (among many others). On the 1st of October the Festival is ending with a big event at the Badeschiff in cooperation with the viennese Waves Festival.
CODED CULTURES was initiated by the group »5uper.net«: a network of producers, theorists, artists, designers, architects and programmers, which is active in the field of knowledge-work based on digital media related forms of art and culture. Recently, the Book "Coded Cultures: New Creative Practices Out of Diversity" published by Springer.
