Laowa Magic Format - adapt your FF lenses to medium format Wed, 24 May 2017 02:49:09 -0600 Vitaliy_Kiselev 17001@/talks/discussions image

Venus Optics, the camera lenses manufacturer who had previously launched a number of unique Laowa camera lenses, is proud to announce the Laowa Magic Format Converter (MFC), the world’s first Fujifilm GFX adapter with optics for Canon/Nikon Full Frame lenses. The patented optics system inside the MFC will enlarge the image circle of any full frame lenses and fit it onto the relatively larger Fujifilm GFX- 50s camera sensors. It has a focal length multiplier of 1.4x and reduces the maximum aperture by 1-stop.

The Laowa Magic Format Converter (MFC) is different from the simple GFX adapter existing in the market. The GFX adapter currently available in the market simply adapts the Canon/Nikon lenses onto the Fujifilm G-mount body with no resizing on the image circle. However, due to the relatively smaller image circle of Canon/Nikon full frame lenses, most of the them are not able to completely fill the Fujifilm GFX sensors, resulting in a vignetting (Dark Corners) or heavily degraded peripheral sharpness in the images.

Our Magic Format Converter (MFC) took advantage of the short flange distance of mirrorless cameras and incorporated a patented optics system to expand the image circle of the lens without compromising the image quality. The enlarged image also corrects the vignetting and maintains the optical performance of your lens in the medium format system.

The Magic Format Converter (MFC) is particularly useful for ultra-wide angle lenses. Vignetting tends to be stronger when we adapt an ultra-wide angle full frame lenses onto the GFX sensors. By using the MFC, GFX users will be able to enjoy an ultra-wide angle of view without the need to crop away all unusable corners of the images. When the MFC is used with our Laowa 12mm f/2.8 Zero-D lens, it will become a roughly 17mm f/4 lens in GFX-50S. The angle of view will be around 116° (equivalent to appr. 13mm lens in 35mm format), making it one of the widest lens available for the GFX system. The MFC opens up a lot more ultra-wide angle lens options for the new Fujifilm GFX camera and increases the compatibility of full frame lenses to the Medium Format cameras.


The Laowa Magic Format Converter (MFC) will come with 2 variants, Canon EF to Fujifilm G & Nikon AI to Fujifilm G. They are expected to start shipping in July 2017. Pricing will be announced later. More sample images in RAW and JPEG format can be found in the dedicated page of our official website.

Looking how to adapt some older lenses to the GH4 Tue, 09 May 2017 22:08:29 -0600 ForrestGray 16892@/talks/discussions Hello!

I recently purchased a Helios 44-2 58mm lens as well as a Jupiter 12 35mm lens. I did a little research and purchased I believed to be the correct adapters to use the lenses on my Panasonic Lumix GH4. Sadly, I've grabbed a 'Keycay L39 to M4/3' and a Fotasy L39 to M4/3 neither which allowed me to focus the lens once secured to the camera.

Im also wondering what kind of adapter would allow me to use the Jupiter lens, as well.

Any input is appreciated!

Techart PRO Leica M - Sony E Autofocus Adapter Sat, 13 Feb 2016 15:22:52 -0700 Vitaliy_Kiselev 14578@/talks/discussions

Available now at


Techart, the Chinese adapter manufacturer who has previously launched the first Contax G autofocus adapter for Sony E cameras, has unveiled the world’s first Autofocus adapter for Manual Lenses named ‘Techart PRO’. The Techart PRO adapter is able to drive the manual Leica M lenses to reach focus by using the focusing system in Sony A7II and Sony A7RII, giving an unprecedented new user experience for all Leica M lenses owners.

Techart PRO has adopted the z-shift technology where the Leica M bayonet is able to extend and retract. The distance between the lens and the camera sensor is hereby changed in order to reach the focus. The mechanism is quite similar to Contax AX system where the flange distance is changed for autofocusing. Techart PRO has electronic contacts to communicate with the Sony A7II and Sony A7RII and uses its PDAF system to measure focus. The built-in motor will then drive the bayonet forward by a maximum of 4.5mm and reach the focus point for shooting.

Techart PRO is super light and powerful. The adaptor weighs only 133g and is able to drive a lens system as heavy as 700g. Apart from pairing up with the Leica M lenses, users can also further adapt lenses with longer flange distance (e.g. Leica R, CY, PK, MD, etc) with add-on adapters and enjoy the autofocusing experience with other manual lenses. Techart PRO supports both AF-S and AF-C modes and it can also serve as a close focusing adapter which can reduce the minimal focusing distance of the lenses.

A complimentary mobile app will be available for users to save 10 sets of lens data to the adapter and perform firmware upgrade via bluetooth.

Techart PRO is an evolutional product which can give users a completely new experience with their manual lenses. The fast and precise focusing allows users to take quick and sharp photos with their favourite manual lenses. More product information and testing videos can now be found via our official website

Pricing and Availability

The Techart PRO Autofocus Leica M Adapter for Sony E cameras is currently available for pre-order at our official website ( The recommended retail price is USD 349/pc. Free shipping will be provided during the promotion period. Delivery will commence from March onwards and will be shipped from our US/UK/Hong Kong warehouse. 1-year warranty is included.

2017 Variable ND discussion Mon, 03 Apr 2017 22:02:38 -0600 webarchitect 16685@/talks/discussions Read through results for search "Variable ND" on this forum, and plenty of other Googling. New products and specific concerns prompt this thread.

Sensors seem to be a factor when considering variable ND, IRND, or stacking. For the purpose here I'm using a GH4 (GH5 will come soon) for video. Maybe that doesn't matter, maybe it does?

There's a fair amount of acknowledgment that variable NDs cause a loss of sharpness in telephoto lenses. I often use the 35-100 2.8 Panny at the long end and have observed as much using the Fotga variable ND. I'm looking for something better.

There appears to be a recent set of arrivals from China touting Schott glass that some find to be solid performers while others dismiss. This would be appealing if they are any good.

Pricing. I don't have an unlimited budget but am willing to spend money to solve problems (like sharpness and color cast). Spending 2x the money for 10% improvement is beyond what I'm willing to do, however.

Thanks to all who contribute here. I read a ton, comment little. I look forward to your thoughts and experiences on this topic.

Need: Damaged Speedboster EF-MFT with electronics Fri, 17 Mar 2017 13:30:46 -0600 Psyco 16603@/talks/discussions I'm looking for a Metabones EF-MFT Speedbooster with lens control/electronics ( or or ).

I want to built a 4/3 to m4/3 speedbooster, to use my 4/3-lenses on my BMPCC and reduce the crop factor. The Metabones is the only one with electronic contacts, on all other adapters the glas element is to large to fit the contacts besides it.

BUT, as I don't know if that really works and I don't want to spend $600+ for an uncertain experiment (the adapter gets heavily modified/milled), I'm looking for a damaged adapter costing not much more than shipping.

Kipon Lens Turbo for Medium Format Lenses Thu, 04 Aug 2016 04:32:31 -0600 Vitaliy_Kiselev 15468@/talks/discussions image

Kipon Baveyes introduces a series of three of the world's first lens adapters that bring the famous medium format Hasselblad V mount optics to Sony A7, Leica SL and Leica M 35mm full frame cameras, virtually eliminating any crop factor image loss and maintaining diagonal angle of view. Your favorite outstanding Carl Zeiss lenses, from wide angle to telephoto, ingeniously compress to a full-frame image, performing just like they were 35mm format full frame optics. The transformation results in a 0.7x factor to the original lens focal length with a gain of one stop in lens speed. Foremost in the advanced adapters, is the custom designed five element multicoated formula by German optics research institution IB/E OPTICS, with the ability to use full frame SLR lenses on crop sensor camera bodies and mirrorless cameras. The Baveyes tele-centric formula is exclusively designed by IB/E Optics in Germany to only the utmost precision and quality. Hasselblad lenses by Carl Zeiss are legendary for contrast, flare resistance, color saturation, bokeh and are in a class of their own compared to even the best 35mm format glass. And the Sony and Leica image sensors, in the heart of their robust camera bodies, give new life to the Hasselblad/Zeiss heritage.

SLR Magic Variable ND mkII Mon, 28 Sep 2015 10:53:40 -0600 Xenocide38 13849@/talks/discussions Having used a variety of bad variable NDs, I was quite surprised with the quality of this SLR Magic Variable ND. At $180 (for the 77mm version) it's not the cheapest ND available but it fixes a lot of the issues I've encountered using other variable NDs: sharpness, polarization, ghosting, etc. Definitely worth it if you want to invest in something that's going to give you good results.

Lens Turbo II (FD to M43) + FD 50mm 1.4 - cant mount lense so aperture works Mon, 06 Mar 2017 02:40:43 -0700 baschmir 16548@/talks/discussions Hi dear forum,

I just received my Lens Turbo II and tried to mount my FD 50mm 1.4 but I cant make the aperture work. I bring the red dot of the lens to the yellow dot of the adapter and twist it towards the red dot (so red dot of adapter and lens match up). While I do that i can feel that the metal screw of the adapter is moving the aperture hock (dont know how that is called), but when the red dots are lined up so the entire lens should fit into the adapter to move again in the other direction its not possible because where the screw is placed the lens pops out a bit and is not fitting into the adapter. if I lift the lens a bit and put it back it fits but the metal aperture hock is not in place anymore and when i screw the lens on the aperture ring is not functioning. i have looked for solutions online, found one guy that said for him it worked to make the screw of the adapter bigger with some rubber because in his case the screw was not lined up with the aperture hook of the lens (thats not the same in my case). tired this as well, funnily one time i somehow manage to get the lens on the adapter with the aperture working but after that always the same (it pops out a bit so i cant mount the lens on the adapter). I made a video, hope you can see the problem there

please help!

IR filter for BMCC Thu, 12 Dec 2013 10:38:03 -0700 theconformist 9069@/talks/discussions Recently purchased a BMCC and have a question regarding IR filters. My plan is to get an IR filter and use it in front of the ND filters I already have though I understand it's probably better to just replace my whole set with IRND's to reduce the chance of ghosting, etc but I can't afford to do that. I've heard IR or IRND filter is recommended passed 1.2, my question is if there is a negative effect to using the IR when it is not needed? Like if I just leave it in the matte box all the time or use it with .6 or .9 ND filters?
