Core FX9 V-Mount Adapter and Core Hypercore Neo Mini Batteries.

One of the things about the FX9 that makes no sense is it’s external DC input. When you are using just the camera body the FX9 requires a rather odd-ball 19.5 volts to power it via it’s DC in connector. Most cameras have a 12v to 16v input range so they can be used with the multitude of V-Mount or Gold Mount batteries that are common place in the world of professional video. But not the FX9.  The FX9 is also fairly power hungry so the standard BP-U batteries can be a little limiting, especially if you also need to power any accessories as the camera doesn’t have a power output. A V-Mount battery will run the camera for a long time and they generally have D-Tap power outlets, but they are the wrong voltage for the FX9s external input. So if you want to use a V-Mount battery, as I do, then you need not only a mounting plate but also a voltage converter.

The adapter I have chosen to use is manufactured by Core. Why this one? One thing that was important for me is not only to be able to power the camera from a V-Mount battery, but also to be able to power it from a standard external 12 volt power supply such as found in most studios, or something like a car battery. The Core CXV-FX9 adapter includes a voltage regulator that takes the 12 to 16 volt range of a typical Lithium battery and converts it to the 19.5v needed by the FX9. It also has an industry standard 4 pin XLR connector that you can use to power the camera from a 12v external power supply.

The Core FX9 V-Mount adapter has an industry standard 4 pin XLR input for standard 12v power supplies.

Hot Swap:

If you have a power supply connected to the 4 pin XLR you can hot swap the V-Mount batteries. If you have a battery on the adapter you can hot swap to and from the external power. During hot swapping the adapter not only continues to feed the camera with power but also the 2 D-Tap ports on the adapter remain powered.

Low Battery Warning:

One issue that all these adapters have is that they have to convert the battery voltage up to 19.5 volts and this is what is fed to the cameras DC in connector. This means that the camera has no direct connection to the battery, so it has no way to know the charge state of the battery. All you will see in the viewfinder as an indication of the output of the voltage converter. This will remain at a constant 19.5v all the way until the battery is flat and cuts off, at which point the camera will just die. That’s not good, if you are halfway through recording something it could corrupt your media. You won’t have any warning in the camera of the battery going flat.

To try to address this at least in part the Core adapter has an LED light on the operators side that is green when the battery is well charged, but turns to red when there is only around 10% of the batteries capacity left. This does at least give some warning of a battery about to die.

The Core FX9 adapter has an LED battery status indicator that turns red and flashes when the battery voltage gets low.

As well as the adapter, I’m trying out a couple of Core’s Hypercore Neo Mini batteries. These are nice, compact 98Wh batteries. They are UN Tested and certified so meet all the requirements for air travel. These batteries have a clever LCD display that displays the available run time of the battery. This is much more advanced than a simple charge indicator (it has one of those too). The battery actually detects the load being drawn from it. It also knows the exact state of charge of the battery.

Core SWX Hyoercore Neo Mini 98Wh battery with incredibly accurate run time display giving the time in minutes until the battery will be flat based on the cameras power draw.

Using these it is able to calculate with great accuracy how long it will be before it will be flat. I have found this to be remarkably accurate, typically to within just a few minutes. I’ve been using this display to let me know when I need to start thinking about changing the battery. It’s accuracy gives me the confidence to continue shooting until I’m down to the last few minutes of run time. Typically I’m getting around 2.5 hours without the Atomso Ninja recorder and just under 2 hours with the Ninja from one of these excellent little batteries.

There are two D-Tap power outlets at the top of the Core FX9 V-Mount plates as well as 3 1/4″ mounting holes for accessories.

Attaching the adapter:

Attaching the adapter to the camera is easy. It uses the same mounting points as Sony’s XDCA extension unit. So there are lugs that slide into slots inside the FX9’s battery compartment as well as two small bolts that attach it to the top of the camera. This makes it incredibly secure with no wobble or other movement. I would have no concerns about supporting the entire camera rig from the battery adapter or adding perhaps a V-Mount wireless video link and then large or heavy batteries behind that. It’s very secure and it looks like it’s meant to be there. Another nice touch is that as well as the 2 D-Tap power ports on the top of the adapter there are also 3 additional 1/4″ mounting points for accessories such as monitors or wireless receivers etc.

I do have one small criticism. The position of the D-Tap ports is quite close to the edge of the adapter. If you are using a tall battery and you have a very fat D-Tap plug they can interfere with each other.

Despite this the Core V-Mount battery adapter gets a big thumbs up from me. The voltage indication is most useful as is the ability to use a normal 4 pin 12v XLR feed.

MTF Services to provide 4/3rds and FZ mount options for Fujinon MK lenses.

MTF-FZ-MK-895x1024 MTF Services to provide 4/3rds and FZ mount options for Fujinon MK lenses.In addition to the recent announcement from Duclos, MTF services in the UK have just announced that they will be introducing a conversion service for the popular new Fujinon MK zoom lenses. Currently these lenses are E-Mount only, but MTF will be producing kits to convert the lens mounts so that they can be used with cameras that use the micro 4/3rds mount as well as the Sony FZ mount. This is great news for owners of Sony’s F5 and F55 cameras.

Here’s the text of their press release:

Since the launch of Fujinon’s MK lenses in February this year, users have continued to request a greater range of mounts beyond the native E-Mount that can be found on the 18-55mm and 50-135mm lenses. MTF have now addressed these requests and have designed brand new solutions to convert the lenses to Micro four thirds and FZ mount systems

Mike Tapa, Managing Director at MTF Services said: “Since these excellent lenses from Fujinon were launched earlier this year, we’ve had more and more of our customers asking for us to produce a solution to open up the use of the MK lenses for use across a broader range of camera bodies. We’re now pleased to announce that we have designed brand-new adapter mounts for both micro four thirds and FZ systems to work seamlessly with both the 18-55mm and 50-135mm lenses.

Fitting service

 

Fitting the new mount options for the Fujinon MK lenses will be offered as a service from the team at MTF Services. Simply ship your lens over to MTF’s London-based workshop, and the team will fit your preferred mount before shipping back to you, fully tested, professionally adapted, cleaned and ready for use before being safely couriered back to your door.

Image quality with B4 ENG lenses on large sensor cameras.

DSC02056 Image quality with B4 ENG lenses on large sensor cameras.
2/3″ B4 lens on the FS700via the MTF adapter.

This is something that comes up a lot and I get many questions about. In part because I designed the MTF B4 to Canon, FZ and E-Mount adapters. Budget adapters that allow you to use a 2/3″ B4 ENG lens on a Super 35mm sensor by using the lenses 2x extender or on a center crop sensor without the 2x.

The question is… what will the pictures look like?

The answer is… it depends on the lens.

Not a very helpful answer perhaps, but that’s the truth of it. Different lenses perform very differently. For a start I would say forget 4K. At best these lenses are suitable for HD and you want to have a great HD lens if you want good HD pictures.

But what about the “look” of the images? My experience is that if you put a wide range ENG zoom on a S35mm camera the look that you get can be best described as “2/3″ ENG look with maybe shallow depth of field”. Lets face it, ENG lenses are full of compromises. To get those great big zoom ranges with par-focal focus there are a lot of glass elements in those lenses. Lot’s of elements means lots of places where CA and flare can occur. The end result is often a lowering of contrast and color fringing on hard edges, the very same look that we are used to seeing on 2/3″ cameras.  Typical cine or DSLR lenses tend to have simpler optical designs. Prime lenses are normally sharper and show better contrast with less flare than zooms due to there simpler internal design.

So don’t expect to put a typical B4 ENG lens on your S35mm camcorder and still have that crisp, high contrast digital cinema look. Of course B4 zooms are handy for the ability to zoom in and out through huge ranges while holding focus. So an adapter and lens may well make your S35mm camera more versatile. But if you want the best possible images stick to cine style lenses, DSLR lenses or zooms designed for S35.

 

Metabones FZ to Canon Mount.

Metabones Sony FZ to Canon EF adapter.

There was one of these at IBC last year. A new version appeared again this year at IBC and it’s really nice. I so hope that this becomes a real product. It fits the Sony PMW-F5 and PMW-F55 cameras (and I must assume the PMW-F3 too). It takes it’s power from the camera and will control a Canon EF lens. Aperture is controlled by a large aperture ring which has clear aperture marking visible at the side of the adapter. No fiddly knobs or dials, no power cable and a real aperture scale. In addition I believe you will get an aperture display in the viewfinder. The EF Lens mount features a large locking ring so the lens won’t twist or rotate once mounted, something essential if you are going to use a follow focus. This version was much nicer than the one shown last year. I really hope it becomes a real product as I’d like one for my F5.

Commlite full frame EF to NEX lens mount adapter.

My old Metabones MK1 adapter is not suitable for full frame lenses on the new Sony A7s. So in anticipation of the arrival of my A7s I ordered a cheap CommLite full frame autofocus ready adapter on ebay. This adapter (CN-EF-NEX) was only $90 USD so I thought I would give it a try, much cheaper than the metabones.

To be honest I wasn’t expecting much, but now I have the adapter in my hands I am pleasantly surprised. It appears well made and very solid. It even carries a CE mark. It works just fine on my NEX5N and FS700. On the NEX5N I have working autofocus. If the lens has image stabilisation this works too. I have tried a wide variety of Sigma and Tamron Canon EF lenses with it and they all work. Even my new Tamron 16-300mm works with this adapter, this lens doesn’t work with a number of other adapter.

Autofocus is a little slow, especially if the light is bad. Having not used the MK3 Metabones I don’t know how this compares but certainly this adapter works and is quite useable. It’s said to be compatible with full frame lenses on the A7, but as yet I have not been able to test this. The little mounting post is easily and quickly removable, but a real boon on the NEX5N with bigger lenses. For the price, you can’t go far wrong, really quite impressed considering how little it cost.

Video overview of MTF Services B4 2/3″ to super35mm adapter.

In this video I take a look at the MTF Services (http://www.lensadapter.com) B4 2/3″ to super35 mm lens adapter. This adapter allows you to use a conventional 2/3″ ENG zoom lens on most video capable cameras that have a Super35 sized sensor or APS-C sized sensor. It comes in two parts, the optical converter (the expensive bit) and a simple low cost lens mount adapter ring. Adapters are available to work with the Sony PMW-F3, Sony E-Mount (FS100, FS700, EA50, NEX5 etc) as well as Canon EF (C100, C300, C500, 7D, 550D etc). To work correctly the lens must have a 2x extender. All is explained in the video.

 

Metabones EF to E-Mount smart adapter.

Metabone EF to E Mount adapter on Sony NEX-FS700

The new $400 Metabones EF to E-Mount smart adapter allows you to use Canon EF mount lenses on almost any camera with an E-Mount. So that means cameras like the FS100, VG10, VG20 and the NEX series stills cameras. I’ve been trying to get hold of one of these for some time, but they have always been out of stock due to popular demand. However I was lucky enough to track one down from a UK dealer a couple of weeks ago. It is a small compact device, there are no wires, cables or remote control boxes so it couldn’t be simpler to use. Simply attach it to the Sony E-Mount and then attach your Canon EF lenses to the adapter. The camera will then control the iris just as it would with a Sony lens. So in the case of a FS100 or FS700 the iris wheel will control the iris with an accurate display of the iris setting on the cameras LCD screen. You can also use the auto iris functions. For quick focus checks there is a small button on the barrel of the adapter that momentarily fully opens the iris so you have minimum depth of field, which makes it easier to see if you are in focus. The adapter doesn’t work with auto focus so no focus functions, but it does allow any image stabilisation built into the lens to work. It works with the vast majority of lenses although there are a few that don’t work or have some limitations, best to check the Metabones web site for details. I really like this adapter for it’s simplicity and transparent operation, you really don’t know it’s there. Just wish they could do one for the Sony F3.

Coming Soon: A review of the new Transvideo PMW-F3 base plate that completely replaces the underside of the F3 with a really nice bottom end and of course the Alphatron EVF-035W review.

Triad E-Mount to PL adapter

A little while back I was loaned a Triad PL to E-Mount adapter for review. E-Mount is the Sony mount used on the NEX-FS100, NEX-FS700 as well as The VG10, VG20 and NEX stills cameras. While more and more E-Mount lenses are becoming available from Sony and other DSLR lens manufacturers there will be many times when something more suitable for video work might be needed. One of the big issues with DSLR lenses is the very small amount of rotation on the focus ring to go from near to far, often only 45 degrees which makes accurate focus tricky. A good PL mount lens will have over 180 degrees of rotation. PL has been the industry standard for movie cameras for years and most rental companies have large ranges of PL lenses to choose from. So the ability to be able to use a PL lens on any super 35mm camcorder is always welcome. While I use DSLR lenses on my cameras for my day to day shoots, if I am doing a high end production such as a commercial then I will hire in the appropriate PL lenses for the job. Sony’s soon to be released FS700 is a camera that will, I’m sure end up getting used for many commercials as slow motion is a technique widely used to show off new products or ideas. As a result there will be many time in the future where I will need a PL adapter.

IMG_1001-300x224 Triad PL to E-Mount Adapter.  A PL adapter for the FS100 and FS700.
The Triad adapter showing the Flange Back adjustment ring.

The Triad adapter is very solidly made, machined from high grade alloy with stainless steel and chrome plated steel inserts. One of the very nice features is that the adapter has a built in adjustment for the back focus distance. A locking outer ring on the adapter can be rotated to alter the physical distance between the PL receptor and the E-Mount bayonet. This will allow the user to calibrate the back focus or flange back distance so that the focus witness marks on any PL lenses will be 100% accurate. It will also ensure that PL zooms will track focus correctly through the entire zoom range. As the FS100 and FS700 don’t have built in back focus adjustments this really is a vital thing to have. The Sony E-mount was only designed to support the weight of light weight DSLR type lenses so the Triad adapter has a support post that can be attached to 15mm or 19mm rails (via a suitable bracket) to help carry the weight of heavy PL lenses without over-stressing the cameras E-Mount. One note from Triad is that the Sony PL lenses supplied with the kit that comes with the PMW-F3 do not fit this adapter. There are quite a few PL mounts that don’t accept the Sony PL lenses without shaving a bit of metal from the Sony lenses mount. So this isn’t a flaw with the Triad adapter, it’s a non standard quirk of the Sony PL lenses.
There’s really not much more to say about this mount. It’s well made and does what it designed to do.

I’ve been asked a couple of times for some frame grabs shot with one of the MTF B4 to super 35MM adapters that I designed. Well, here they are. Shot on a Canon C300 fitted with the adapter and an old standard definition Canon J16 zoom lens. It was late in the day when I shot this so it’s not showing the adapter in its best light and of course an HD lens would be even better.

MTF - Alister C' B4 to F3/FS100/Canon lens adapter

So here it is. The first one off the CNC machine with many more to follow in the next few days. There will be an additional lens support bracket on it by the time they ship and of course they will be completely anodised. It requires the use of a 2/3″ lens with a 2x extender. Optical performance depends on that of the lens, so an HD lens is highly recommended, however if you have an old SD lens kicking around it may be useable. When using the adapter you use the 2x extender. The total magnification is 2.5x so a 7.6mm to 152mm 20x ENG lens becomes a 19mm to 380mm lens. There is also a 2.5 stop light loss so a f1.8 lens becomes a f6 lens. The adapter will come as a kit for the PMW-F3 or FS100 for £1150. If you wish to use it on a Canon DSLR with an APS-C sized sensor (7D, 550d, T2i etc) the price is £950.
