While I see many people switching over to the Panasonic GH4 and Sony A7 series cameras (like the A7sII/A7RII), there's one product that I wanted to remind people about - the FotoDiox ND Throttle. When shooting with Sony cameras, especially in SLOG, the minimum ISO could be anywhere from 1600-3200. SLOG is such a great option to have, but means you really have to deal with ND Filters to keep a wide aperture and proper shutter speed.

The easiest and most simple solution that I know of is the FotoDiox ND Throttle. The FotoDiox ND Throttle is a variable ND Filter built right into a lens adapter, and allows you to dial in your exposure without changing your ISO, Shutter, and Aperture. Of course this only works if you are adapting a Full Frame lens to the Sony or Panasonic, and not using a native lens.

It doesn't matter if you're working with a Canon EF autofocus lens, a manual Rokinon Lens, or even high end Cinema Prime Lenses like the
XEEN, Canon CN-E, Zeiss CP.2, etc. The FotoDiox ND Throttle is one simple adapter that I highly suggest all Sony A7 series or GH4 shooters look into and find the time to try it out. Even if you're not using it all the time, I think you'll find it's worth keeping in the gear bag.

So while I think Canon L lenses offer great image quality, you can get a (4) piece Rokinon Cine DS Lens Bundle Set for about the price of one Canon L Lens. The DS line from Rokinon are designed to be color matched, same exposure ranges, common focus and iris gear positions, a de-clicked aperture, etc. For me personally I feel they are better for video than standard Autofocus Photo Lenses (image quality aside). If you're looking into a set of Rokinon Cine lenses, I highly suggest starting with the 'Cine DS' line for the reasons stated above.

The image quality is great, and I think you'll really appreciate the longer focus (pull) throw, and de-clicked aperture which lets you set F-stops in smaller increments than you can with auto focus lenses. The built in gear ring is great for follow focuses, and the standard positions make it easier to swap lenses without moving your FF around each time.

Now if you really want to step it up a bit, the Rokinon XEEN Cinema Prime lenses have a standard physical size, lens diameter, better optics, less breathing, etc. To date they are probably the most affordable Cinema Prime Lenses that cover a full frame sensor. They have a 114mm Diameter which is exactly the same as a Canon CN-E Prime, or Zeiss CP.2. You can find great deals on XEEN Lens Sets via eBay (click here).

When it comes to smart adapters for Canon EF lenses that allow you to adjust the iris, your selection is limited and pricey. Over at the 2014 NAB Show in Las Vegas, I stopped by the Aputure booth to look at a brand new concept Canon EF to mirrorless Lens adapter.

This new DEC concept is an adapter that not only can adjust the iris on the Canon EF lens, but can also adjust focus through a wireless remote. This is not the same method used from USB follow focus systems where it requires the lens to 'step' in increments. What I saw was very smooth, and they confirmed it is using a different more accurate method.

The adapter also offers a LANC cable for start / stop video. It uses an internal battery, so everything can be completely self contained. An LCD screen on the side of the adapter shows the lens focal distance and aperture value. The same LCD on the remote also shows this information. The remote can store A/B limits so that you can return to exact focus points. A throttle on the joystick controls how fast or slow to focus.

I'm not a fan of the single hand joystick, but they did mention on designing a more 'standard' wireless follow focus remote with marking disc. Do away with lens gears, 15mm rails, and external follow focus motors. An adapter like this will easily appeal to those working with Steadicams or Active Gimbal Stabilizers. So far this product is not yet available on the main website, so please leave your comments, suggestions, and feedback here in this article (comment here).

This thing took about 13 days to ship to California, but it's finally here and i'm pretty impressed. This adapter allows you to mount Canon EF lenses to the Sony NEX camera and control all of the aperture settings natively. I haven't tried it yet, but it should communicate with the lens and store EXIF information into your photos as well. As you can see from the video it works pretty flawlessly, responds very quick, and build quality is very nice. To enable IS when taking photos, you would hold the shutter half way down - or that's what I had to do to get it going. During Video Mode, the Image Stabilization is on as soon as you start recording.

I didn't have much time to test everything as i'm getting ready to fly out for PhotoPlus, but I did try to 'wig out' the adapter. When removing the lens while the camera was still powered on, the aperture controls didn't come back. The adapter does not like hot lens swaps. Simply powering the camera down doesn't always help, but removing the entire adapter from the camera body and then starting over always works. There is another Metabones adapter out there that can adapt EF lenses to NEX cameras, but it's about twice the price. I have not had the chance to test this on an FS100 or Sony FS700, but i'm hopeful it should work seamlessly. If you're shooting on the Sony NEX system, you might want to give this guy a try. You can find this Canon EF Lens to Sony NEX adapter via eBay (Click Here).
