Three names come to mind to bring this lens production ready: Bernie O'Doherty in New York Edward Koehler in Germany Les Bosher in Wales.

Does anyone have other recommendations for engineers who can do this work?

TIA

Very good to excellent condition, has only some cosmetic imperfections on the outer lens body, lenses are clean without scratches or other imperfections, focus and aperture rings are fluid. Comes with a front lens cap, a quality c-mount to m4/3 adapter and 40.5mm to 58mm filter step-up ring

It looks like the topic of using 2/3" Eng lenses has died down a bit.

I recently was selling a Servo Powered Zoom Grip with Power Cable and a Battery, but no one seemed to want it ??

After reading numerous posts in the various forums and blogs about people burning out their servos trying to power their lenses, I thought for sure that someone would want to buy a replacement... but no bites.

I think people out there need them, but don't think they will have any luck finding one so don't bother looking in the first place.

Please check out my videos by following the links below. On is for the Grip that I was selling on eBay, and the other is about a lens that I'm selling.

One video explains why and how I built the adapter cables, and the other shows the features of the Fujinon lens that I'm selling. The features include examples of the zoom characteristics.

I would appreciate your feedback, especially about where I might find people who need replacement grips... Where can I find them??

So I have a Fujinon E6X14AM f/1.6 14-84mm TV Zoom lens that's C mount. What I'm trying to understand is what sensor sizes this lens will be compatible with for conversion. Can anyone help me out?

Also, I wanted to know if someone could link me to a site/document that explains which dimensions on the rear mount of a lens determine which sensor sizes it will cover.

Your help is much appreciated.

Thanks!

Thanks a lot!

I have several Fujinon A20x8.6BERM lenses from a Sony Digital Video Camera DXC-D35.

I've searched the net to see how well this lens would work on my GH3 with an adapter but cannot find anything.

Here are the specs on the Lens according to: http://www.fujifilmusa.com/products/optical_devices/broadcast-hd-sd/sdtv-lenses/2-3-pro/a20x86-berm/

Note: It says the aspect ratio of the lens is 4:3...Can a lens be set for that? I thought that was determined by the camera recording format, not the lens. (my apologizes for the noob question. I'm still learning).

What are your thoughts on this lens for micro four third use? Would I be able to set up an external power supply on my rig to use the zoom feature?

I just recently wanted to buy a fisheye lens to filming skateboard videos, but I came across 2 different fisheyes :

• The Rokinon 7.5mm f3.5 for Micro 4/3

Or

• The Rokinon 8mm f2.8 for Sony E-mount (NEX-7, NEX-5, NEX-3...) + Adapter

The thing is I know the Rokinon for M4/3 is going to fit directly on my camera (tried it in a shop), but the Rokinon for Sony is much faster, but maybe a little less wide...

Can you please help me choose ?

Thank you.

Everything is in great working order, and good to great cosmetically. The lens covers the equivalent of 31mm-438mm, a 14x range! This lens is a legend and a workhorse, not clinically sharp, but still holds great detail, especially in the center... a great match to the super sharp GH2. Comes with hand mount and the power zoom should work fine if hooked up to a 12v power source.

I'd prefer to sell as a set, but would be willing to part it out if the lens were to sell first. Asking $885

I'll get pics up tomorrow, I'm happy to answer any questions.

Thanks.

I want to power also the zoom to get this ENG-stile of shooting. If possible I want to start and stop recording via the trigger at the zoom handle, but I might skip that, because I might loose the ability to use the mic-port for an external mic. I doubt that both is possible at once... Anyone experiences using a Y-splitter?

As a premixer I thinking of a Rolls MX 54s Audio, or a juicedLink CX231 Audio Mixer. I planing to use a Varavon Screen Loupe EX GH1/GH2... The only thing I can tell at the moment - the hack worked great. I´m using a SanDisk extreme pro 64 GB and started with the "no adverse settings". But with 42 mb/s no constant recording ( at least one hour in AVC 1080/50i) was possible. So I altered the settings. I will use for narrative film making a FSH preset with 42 mb/s and for events a FH preset with 32 mb/s. This works so far... Quality wise I tested my gh2 vs. my old JVC GY HD 200B (1440x1080 50i). I recorded the same motive at the same time and I have to admit the JVC can´t compete against the gh2´s resolution… and that´s the reason I´m doing all that here.

I wish they made similar lens for MFT :-)

IMHO , love the Nokton at all , nikkor got strong bokeh cool colors and is sharp , Fujinon got very nice pearly bokeh but is very soft .

hope You enjoy cats ; )

The lens is in great condition, I dare say the optics are in near mint condition, save for a few specks of dust. It has a 2x extender which covers the entire Micro Four Thirds sensor. However it drops about 2 f-stops. But you can also use GH2's Ex Tele mode to retain aperture speed. This makes the lens become 18-252mm f3.5(ish). The lens is parfocal!

Demo:

The original motor system is included and has a Hirose cable that was intended for broadcast cameras. The motor system can be detached. There is a macro function allowing you to shoot close-up. It also comes with original hood and generic front cap. The lens + adapter is 1.7kg. On the handle grip I stuck some Sugru to improve ergonomics (refer to last pic). If it doesn't fit for you it is removable. Or, I can remove it for you if you want. The B4 adapter is the best quality made one by ciecio7 from Poland, worth $320 new. The tripod mount is super strong, made of duraluminum unlike the other simple aluminum adapters. It holds up the lens very well - this is important as the lens is much heavier than the camera. It also comes with a rear Micro Four Thirds cap and its original B4 rear cap.

The Hirose to 12v cable allows you to connect the motor system to a 12v battery, allowing you to operate the servo zoom. This made it really handy when shooting, allowing you to zoom and focus simultaneously. There are no auto focus or iris functions. Below is a sample video utilising a battery with the motor system (battery is not included in this auction!). Search "12v lithium battery" on eBay or whatever and they're very cheap and light. Make sure to get ones with plug ports so you can insert the Hirose cable. You could use gaffer tape or velcro to affix it on the lens or rig.

I'm asking for US$600 + shipping via PayPal (fees inclusive).

I ship from Hong Kong to USA, Europe, Asia and Australia with fast EMS mail. You can check rates here: http://www.hongkongpost.com/speedpost/eng/rates/index.htm

Here is the only video I did with it using a hacked GH2: http://www.cosmogirl.com.hk/videos/lifestyle-videos/cosmogirl-x-samsung?qt-cgvideo=#qt-cgvideo

Please PM me for questions instead of posting here, or whatever you feel like. Just don't want to hog up the forum. cheers

As I am resolving all my gear, i can't sell individual items, just the whole sets.
