Newsshooter at NAB 2014: Fotodiox B4 lens adapter solution for Micro 4/3 and NEX cameras

Newsshooter at NAB 2014: Fotodiox B4 lens adapter solution for Micro 4/3 and NEX cameras from Dan Chung on Vimeo.

Newsshooter.com technical editor Matt Allard talks again with Bohus from Fotodiox about the company’s upcoming B4 ENG lens optical adapters. The adapters expand the small B4 image from an ENG lens using optics to cover larger sized sensors such as M4/3 or S35. Because the optics are expanding the image there is of course light loss, but Fotodiox are not giving a figure at the moment. The lens servo unit can be powered using a battery pack via a special cable which allows motorised zooming.

A number of competing solutions already exist. For M4/3 users it is possible to buy a purely mechanical B4 to M4/3 adapter, then use a B4 lens with a built-in range extender engaged to make the lens cover the sensor size. Power cables that power the zoom servo are available on Ebay and other places.

MTF services in the UK have been making an optical B4 to EOS adapter since 2012 that are also designed to be used with the range extender of an ENG lens. We previously tested one here.

What sets the Fotodiox solution apart is the lack of the need for a lens with a built-in range extender, and also the lower cost of the solution. How good the optics are remains to be seen. We are of course keen to see the results here on Newsshooter.com

Interestingly Fotodiox were also showing a version of the adapter on full-frame Sony A7. While they say this is a work in progress I very much doubt that it would be made to cover a full-frame image without too much image degradation and extreme loss of light. Time will tell.

A word of caution about lens choice with all these adapters. In my experience some of the older standard definition B4 lenses don’t work well when used this way. Distortions in the corners and chromatic aberrations can be very obvious. Try to test your B4 lens with the adapter first before buying to be sure you are comfortable with the results.

The very best solution I’ve seen is Sony’s B4 to FZ adapter for the F5 and F55 with used high end HD B4 lenses. This combination is optically excellent and Sony claim no resolution loss compared to using the B4 lenses on a real ENG camera – although you still lose several stops of light. Sadly this comes at a high price and the solution on works on the F3, F5 and F55 cameras.

NAB 2014 video: Fotodiox EOS to NEX mount ND Throttle and Wonderpana for Gopro

By site editor Dan Chung:

Newsshooter at NAB 2014: Fotodiox EOS to NEX mount ND Throttle and Wonderpana for Gopro from Dan Chung on Vimeo.

In our most amusing show report ever Newsshooter technical editor Matt Allard is completely upstaged by Bohus Blahut of Fotodiox. In all the shows we have covered I have never seen a sales pitch quite as entertaining as this. Frankly Bohus is wasted selling filters and should probably have his own show in Las Vegas.

The video is about the new EOS to NEX mount ND Throttle variable neutral density lens adapter and Wonderpana GoPro filters, but I suggest you watch it even you aren’t interested in the products just for laughs.

NAB 2014 video: Will your radio mics be unusable soon? A discussion with Sennheiser on wireless frequencies in the USA

By site editor Dan Chung:

Newsshooter at NAB 2014: A discussion with Sennheiser on wireless frequencies from Chuck Fadely on Vimeo.

If you live in the USA and use wireless microphones, or are looking to buy a set soon, then this issue concerns you. Newsshooter’s Chuck Fadely talks David Missall from Sennheiser about the upcoming FCC auction of the 600mhz range of radio spectrum. This may eliminate wireless mics in Sennheiser’s “B” frequency range along with other manufacturers’ offerings in the 600mhz range.

They discuss the lobbying being done to try and keep parts of the 600mhz band open for wireless mic users, as well as some newer technologies that Sennheiser are developing to work around the problem.

NAB 2014 video: Varavon show $2000 brushless gimbal and $300 GH4 cage

By site editor Dan Chung:

Newsshooter at NAB 2014: Varavon show $2000 brushless gimbal and $300 GH4 cage from Dan Chung on Vimeo.

Our stream of extra videos from NAB continues with this interview by our reporter Li-lian Ahlskog Hou. She talks with Korean firm Varavon about their new $2000 US brushless gimbal. We saw an earlier prototype unit at IBC in Amsterdam last year but the final product looks much more finished. To achieve the price Varavon have based the design on an off-the-shelf Alexmos controller. It has a joystick controller and all the usual functions of an Alexmos based gimbal. It can carry a Canon 5D mkIII or other similar sized DSLR.

Also on show was an upcoming Panasonic GH3/GH4 compact cage, priced around $300 US. With the GH4 looking like it will be extremely popular this is just the first of many new cages and rigs for that camera.

You can find out more about these products at www.varavon.com

Newsshooter’s Clinton Harn checks out all the latest offerings from Edelkrone at NAB. Most eye-catching were the new pocket range of rigs that includes a super small slider. There was also a new prototype arm based slider for smaller cameras that resembles a robotic arm from a car assembly line.

NAB 2014 video: Switronix $35 D-tap power solution for GoPro

By site editor Dan Chung:

Newsshooter at NAB 2014: Switronix external power solution for GoPro from Dan Chung on Vimeo.

On the last day of the NAB show I was wondering the hall and stumbled upon a great little piece of kit from battery specialist Switronix. They make a power supply cable that allows GoPro 3 and 3+ cameras to be run from any broadcast battery with a D-tap power socket. The cable has an in line voltage regulator which means a broadcast battery can be used to power a GoPro for days.

The best thing about this adapter is the price – a bargain at $35 US. Given the relatively short run time of regular GoPro batteries I can see this adapter being extremely popular with news shooters.

They also make a USB power version that can run off a wall charger for $25 US and a cigarette lighter version for car use. For more info check out the Switronix website.

This video in on our last batch of NAB videos that is currently being edited. Sorry for the delay but with the team dispersing to the four corners of the globe things have gotten a little complicated.

Litepanels post 1×1 light kit training video: A handy primer on three point lighting

By site editor Dan Chung:

Doug Jensen of Vortex media has worked with Litepanels to create a handy primer on using their 1×1 panels for simple interview lighting. None of this information will be new to TV folk as Litepanels 1x1s are commonly found at most TV stations, but if you are new to lighting then this tutorial should be useful whichever brand of LED light panel you choose to use. Just be aware that not all LED lights are created equal and the colour of your images may not look as nice as Doug’s if you are using inferior gear.

If you an novice or intermediate level shooter and want to know more about interview lighting technique I can also recommend Den Lennie’s lighting tutorials over on F-Stop Academy.
