Your Fotodiox MFT Adapter Guide

With the announcement of the OM System OM-1 and the Panasonic Lumix GH6, we are reminded that the MFT system is still around, especially in a time when multiple full-frame mirrorless cameras offerings are available. Despite the smaller sensor size, the MFT system has proven time after time that sensor size does not matter. With a strong user base, we have supported the system by providing a large selection of Micro Four Thirds lens adapters. These range from different lens mounts and specialty adapters.

If you’re considering getting the OM-1 or the GH6 or simply curious about adapting lenses on your Micro Four Thirds camera, we will point you in the right direction with this guide.

But before you adapt lenses, keep in mind that there will be a 2x crop factor on Micro Four Thirds cameras when compared to full-frame or 35mm film - this is due to the small 17.30mmx13mm sensor. For example, a 50mm lens would have a field of view equivalent to a 100mm lens. Wide-angle lenses are well suited for general shooting while longer full-frame focal lengths are best reserved for portrait, wildlife, macro, or astrophotography.

That being said, let's dive into the adapter types we offer for Micro Four Thirds along with our suggestions. We’ll also include the top 5 selling adapters for Micro Four Thirds of 2021 at the end.

Our standard lens adapters are inexpensive and offer an all-metal aluminum build. Their accessibility is great for beginners and also for quickly adapting a lens. view more.

PRO adapters feature a premium build that includes a reinforced lens mount, leaf springs, and stronger metal alloy construction. These adapters are made for professional use or for anyone who wants the best gear. click here to view more.

Our FUSION adapters restore electronic functions to a lens such as aperture control and autofocus. Our FUSION series primarily supports Canon EOS EF lenses due to their abundance. We offer two firmware upgradeable options for MFT systems with one having a 0.71x focal reducing optic - known as the MFT FUSION Redux. With this optic, the lens image circle is refocused to fit the camera sensor while widening the focal length and f-stop. This means that a 50mm f/1.2 lens with our MFT FUSION Redux would be reduced to a 35mm f/0/9! view more.

With our TLT ROKR adapters, you can turn any supported mount into a tilt-shift lens, a style of lens that the MFT system has yet to offer. Our TLT ROKR adapters offer 10° of tilt, 9mm of shift, and 360° of rotation. This is a great option for architectural photography, miniaturization effects, and perspective control. view more.

ND Throttle
A first of its kind, the ND Throttle is a series of adapters that have a built-in variable neutral density filter (2-8 Stop). Our ND Throttle is a very popular choice for filmmakers and landscape photographers. We recommend this adapter for video shooters who use any of the Lumix GH cameras. view more.

DLX Stretch**
The DLX Stretch series are helicoid adapters that provide macro focus and correct back focus issues. These adapters also include three magnetic drop-in filters: ND4, ND8, and ND16. view more.

Macro photography is extremely popular and we offer adapters that make it easy to do. We carry macro lens adapters that use a helicoid to expand, turning the adapter into an extension tube. We also have macro reverse rings for mounting a lens in reverse via the filter thread. This essentially turns your lens into a macro one. view more.

A lens adapter that shifts 9mm side-to-side with 360° of rotation. view more.

A premium lens adapter designed with a long-throw aperture control dial. We currently support Nikon G lenses with this style of adapter. view more.

ArtFX ColorFlare
Our ArtFX ColorFlare adapters create organic flaring for a stylized video or photo effect. view more.

Polar Throttle
A premium lens adapter with a built-in circular polarization filter. Much like the ND Throttle, intensity is controlled from a dial on the adapter. view more.

**Not Compatible with Olympus OM-D E-M1 Mark I/II, E-M1X, E-M5 Mark I/II, E-M10 Mark I/II/III

Our suggested lens adapters:

Nikon F
Wide-angle lenses are highly recommended when adapting, that is why we recommended looking into Nikon’s vast collection of wide-angle lenses. There are 60 wide-angle lenses to choose from going as far back as the 1960s. Nikon lenses are well-regarded for their sharpness and build quality which makes them perfect to start a simple lens kit with. view adapter.

Canon FD
With about 30 wide-angle lenses to choose from, Canon FD lenses are the second-best full-frame lenses to adapt with. There is also a variety of great, longer focal lengths to choose from when going down the Canon FD route. view adapter.

Pen F
The Olympus Pen F system is a half frame camera that produces two images on a single frame of 35mm film. The image area is 18x24mm which is similar to a Micro Four Thirds camera. The crop factor of Pen F lenses on MFT cameras is 1.39x. This means a Pen F lens such as the Olympus G.Zuiko Auto-W 20mm F2.8 would be equivalent to 28mm on your MFT camera. This smaller crop factor makes a difference when compared to the 2x crop factor on full-frame. view adapter.

Pentax 110
There is virtually no need to worry about a crop factor when using Pentax Auto 110 lenses on MFT cameras. The Pentax Auto 110 is a 110 cartridge film camera that uses a 13x17mm frame. You also get the added benefit of using Pentax glass known for its amazing resolving power - they’re sharp lenses. view adapter.

C-mount was once used by 16mm movie cameras and is commonly found on security cameras and industrial applications. Both are fun to try out since the image circle is smaller than MFT meaning that you will not always get full sensor coverage. Despite this, C-mount lenses are plentiful and we highly recommend the 16mm lenses. view adapter.

D-mount lenses were made for 8mm movie cameras and have lenses with an even smaller image circle. Wait until you see what stylized looks you can get from these lenses. If you love lomo style photos or video, this is the one for you. You will need to pair this adapter with the C-mount to MFT adapter. view adapter.
