FotodioX EOS-MFT-PRO-IRIS Reviews

Perfect for my needs (GH2 and BMPCC4K)

By Mike
Rated 5 out of 5
Date: 2022-01-17

I've been using this for 7 years now so this is a long overdue review but I just tried a different brand that was much more expensive and immediately went back to my Fotodiox. Solid construction, fits snugly on both my GH2 and now my BMPCC4K, it's my go-to for my budget.

Weird focus problem

These work well with my BMPCC but the only problem I've had with them is that a few lens won't focus when I connect them to the adaptor. I know it's for EF lens and not EF-S and I've put some EF lens on that wouldn't focus. The only lens I had that focused were the 18-55mm standard lens #sweepstakes

Returned. Did not work for me.

I returned this. I don't like the vignetting I am seeing on the outside of the image.

UNUSABLE! SEVERE VIGNETTING...

By John

Bought this for use with an Olympus M10 mark ii, and a 100mm macro lens. The vignetting, is severe, stopped down, as needed for macro. The contrast is also reduced using this. Picture is straight out of camera. Wide open has no vignetting, but as you start reducing the aperture vignetting gets worse. Undeserving of a single star.

Got vignetting?

SEVERE vignetting, might be artsy for others, makes this usable, for me. Photo below is with the Canon EF 180mm f3.5L Macro on an Olympus OM-D E-M10 Mark II body, minimum aperture. Tried a wide range of lenses and apertures. Unless you are shooting wide open, expect vignetting, proportionate to aperture. Photo is straight out of camera.

nice and simple

an easy to use, simple adapter. A great way to save some money if you don't want to purchase a smart adapter which allows you to use a Canon lens' built-in aperture. I bought this as a companion to the Metabones SpeedBooster, so that I can decide which crop factor I prefer while shooting. The aperture has 14 Blades, resulting in nice, round bokeh balls even when stopped down.

Pass

The thing is solid, the iris moves really nicely... but I bought it to use with a Tokina 11-16 and the infinity focus just isn't there. Comes up a little short and that's a deal breaker.

question

I am a little confused on some of the answers for the Can this adapter also be used with EF-S lenses as well as EF? I would like to know if it will work on a Panasonic GH4 with a Canon EF-S Zoom Lens 17-55mm - F/2.8. Please don't answer this question if you don't know. Thanks in advance!

question

will this work on sony a6000
Asked by: Anonymous
The FotodioX Canon EF Pro Lens Adapter with Built-In Iris Control for Micro Four Thirds Cameras would be for mounting Canon EF lenses on cameras with the micro four thirds mount. The Sony A6000 has the Sony E-mount, so this adapter would not be compatible with your camera. For the A6000 you would need the following adapter: FotodioX Adapter for Canon EF Lens to Sony NEX Mount Camera with Iris Control (B&H # FOPNEXACEI).

question

Does this adapter will work with lenses of apertures below f/2.8, like a 50mm 1.4 for example?
Asked by: Anonymous
You will be able to use this adapter with Canon EF lenses with apertures wider than f/2.8, such as the 50mm f/1.4. You will need to set your camera to Aperture Priority or Manual mode for automatic metering.

question

The picture shows some threads on the inside of the adapter. Does anyone know what size these threads are, and if they can be use to mount small filters?
Asked by: Mike
Those are light baffles and are not threaded. They are meant to prevent stray light from bouncing around inside the adapter and causing loss of contrast.

question

Are there any caps for this adapter? I want to protect the iris blades and keep in clean
Asked by: Anonymous
Since the front portion of the mount is the Canon EF mount, you could use the following cap to cover it: http://bhpho.to/1x4zHba
