I'm prepping for my trip to NAB, but I thought I could squeeze in this quick test of the new Aputure DEC LensRegain vs the Metabones Speedbooster S Version. Both of these adapters offer a wider field of view when used with smaller sensor cameras (i.e. Micro Four-Thirds cameras or Sony E-Mount). Since they concentrate more light to your sensor, all of your lenses will end up having faster apertures as well. For instance my Canon EF 100mm F/2.8L Macro shows as an F/2.0 when using the DEC LensRegain.

The test was using a GH4 and an 85mm XEEN Cinema Prime shot in 4K. As you can see the Metabones Speedbooster 'S' Version achieves a wider field of view over the DEC LensRegain. But the adapter is about $650 US Dollars (here). I'm not exactly sure, but the Aputure DEC LensRegain may list for around $500.

Besides the slight difference in field of view, the Aputure DEC LensRegain in my opinion performed very well. Lines look straight, image seemed sharp from middle to corners. There's a good number of cheap focal reducers on the market that can't seem to get the optics right. I can't say it's any better than the Metabones Speedbooster S Version, but I can say that the DEC LensRegain performed far better than some cheap adapters i've tried.

And while certainly cheaper than a Metabones adapter, it does have a trick up it's sleeve. The DEC LensRegain is actually a wireless follow focus system for Canon EF Lenses too. And If you've never heard about the DEC Lens Adapters, take a look at this video I made from the original (non focal reducer) version.

After using it for a while (and after the NABShow) i'll do an official review of the DEC LensRegain, but if this was something you were already looking for and were just waiting for some samples, I can say the optics itself look really good.

With either the BlackMagic Pocket Cinema or Micro Four Thirds cameras, you can always benefit from faster aperture lenses and wider field of views.

The new Fotodiox Excell +1 adapter is similar to other Focal Reducer (Boosted) adapters that will give you a wider field of view and a faster aperture with Nikon or Canon FD Lenses.

I've had this Mitakon Lens Turbo MFT Adapter for a almost a week and I am just getting ready to publish a video showing some examples from this. Recently I noticed an increase of questions and the amount 'buzz' picking up around the Internet, so I wanted to quickly provide some additional important information. THIS ADAPTER WILL NOT WORK ON THE #BMPCC BlackMagic Pocket Cinema Camera. It simply will not fit or attach to the camera.

If you're not familiar with this adapter, it's similar to the Metabones Speed Booster (found here) (but less than half the price). Always a concern on smaller MFT cameras is the cropped sensor. The Lens Turbo adapter offers a wider field of view on these smaller sensor cameras and also increases your Aperture by 1 F-Stop. Your lenses are now wider and faster!

Right now the Lens Turbo MFT / M43 adapter fits Nikon (F, G, Ai, Ai-s, E) manual lenses and should work perfectly on your Panasonic GH3 or BlackMagic Cinema Camera MFT mount (not Pocket Cinema). How well does it actually perform? Give me a few days, and you'll see a video with a variety of examples.

For more info, you can find the Lens Turbo MFT Focal Reducer adapter available now via eBay (click here).

If you caught my recent video shot entirely on the BlackMagic Pocket Cinema, you'll probably find quite a few wide angle shots. That's because I tried very hard to include only native MFT lenses especially the Panasonic 7-14mm & Rokinon 8mm Fisheye.

For anyone looking to adapt non-MFT Lenses (without a speed booster) to the BlackMagic Pocket Cinema Camera, here's what it will look like through a full frame Canon 5D Mark II, Panasonic GH3, and BlackMagic Pocket Cinema Camera.

[Note] In the field of view test, some of the images may appear soft, this is not the fault of the camera. The Rokinon 85mm on a BMPC will be at an approximate 240mm focal distance, and with a Variable ND filter on the lens, things go soft. It's best to use good quality static ND Filters.

In other parts of the video a Canon 70-200mm F/2.8 was used throwing it somewhere close to the 600mm focal range. Since an ND Filter was not used, results were much sharper from the BlackMagic Pocket Cinema Camera.

Judging from the distance of the 5D Mark II, the tripod was quite a distance away. Using the Rokinon 35mm and 85mm lenses, you can tell there is quite a crop factor to the smaller BMPC - more than you would get from a GH3. The BMPC has even more crop than from the original BlackMagic Cinema Camera. That's something to keep in mind if you plan to work in tight spaces. Invest in the right glass, or look for a Speed Booster / Focal Reducer (found here on eBay).

Sony NEX shooters rejoiced when Metabones announced a Speed Booster adapter that offered a Full Frame look on the NEX cameras, but also increased the F-Stop of the lens attached. Check out the quick review from ProCinemaTools.com about the Metabones Speed Booster.

So how does this work? In short, it's similar to a Telephoto Extension adapter that multiplies your lenses focal length. The reason why it's able to perform this same technique in 'reverse', is because it is using a lens designed for Full Frame cams, but is directing the image to a much smaller sensor (like the NEX). The Metabones supports electronic functions like Image Stabilization and aperture can be controlled directly from the Sony NEX cameras buttons and dials, but price ranges from $450-$600 dollars (found here).

Recently another Speed Booster'ish Focal Reduction adapter has been released, but it offers no electronic communication. This one is designed for Nikon manual lenses with manual aperture controls to mount to your Sony NEX cameras (metabones does not currently offer Nikon to NEX). You can use this to achieve a Full Frame look from of your Rokinon (Nikon mount) lenses as well. At less than half the price of the Metabones, this adapter is being listed at $198 via eBay (click here)

When is someone going to make one for the BlackMagic or MicroFour Thirds?
