MTF EOS adaptor for FS100

Got a few minutes to play with Mike Tapa's adaptor that fits Canon EOS lenses to the FS100 with full iris control.


Launch at IBC was a little bit 'oh' when we saw the box, but today's experience has cheered me up no end: the box is only there to set the aperture. Once done, you can unplug it and shoot away. If you set it to f5.6 on your Tokina 11-16, then remove the lens and replace it with a Sigma 50mm f1.4, it immediately sets to f5.6 too. And so on. Set the mount, the mount tells the lens, if the box is attached or not. And there's 1/4" mounting points all over it for Noga arms, and Caleb's mount too.

Interestingly, the box reports the ACTUAL f-stop of lenses that aren't constant aperture.

Pulling iris is possible for 'gross movements', but it's not a fine-resolution thing. Still room for Vari-ND.

Alas not - no hard dates yet, sounds like hardware's done but the devil's in the software. Still testing, found a bug with the Canon 17-55mm 2.8 IS yesterday... Seems like every lens has a different take on how the protocol should be. But it's close!
 
I wonder where the mount gets the power from, as power is required when you put on the second lens before it could possibly stop down to f/5.6.
 
4x AA batteries in the box.

If your only interest is in aperture, then you can unplug the box once aperture is set. If you want IS, then you'll need the box to power it. I wonder what the situation would be with NiMHs.

I can see rising demand for a D-Tap, Canon 5D, NP-F or even USB powered version, run off a V-Lock. Poor Mike, let's let it ship for a bit first!
 
Maybe I am misinterpreting the first post. It sounded like you could remove the box and then put on a second lens and that second lens is set to the aperture you last set with the box. That sounds implausible if the box is the power source. Of course in the single lens scenario you can remove the power source and the aperture remains at where it is last set to. And also of course if the box remains attached you can swap as many lenses as you want.
 
Matt, I've been reading a mid January release date, are you hearing that at all? I need one of these ASAP! :)

He had stated the following:
"Development is complete and it is in production. One more thing to note: there are no external box, external control, external display or external power. Your camera is the box, you control... "

i can't even find the page where you can order it. Are they only ship to those pre-order/beta tester?

I'm looking for the same info but not much out there. Abel Cine is one of their distributors int he states. My guess is it will show there at some point.
 
Why using such a HUGE BIG remote with such a big knob for only control the iris? Isn't is posible without remote but just on adapter? If I hold that remote I only got one hand to operate the rest of the camera.
I think this solution is not so good, rather sell my Canon glass than working with this big brick in my hand wich only enables me to chances iris.

(I edited this post because my first reaction was a little grumpy this morning)

Well I talked with MTF and had such a great conversation, I ordered directly from them this morning. The FS100 mount comes in tomorrow and they are shipping it to me FedEx one day from the UK to the US.

With shipping, which was pricey, it comes out to $1604 US dollars. While I would have preferred to get my power from the body itself, and I'd have preferred to set the IRIS with the body as well, it is definitely better than my current solution, which is nothing. One thing I feel is good about this system is it is probably going to be very dependable.

I will probably mount the box on the camera somewhere. My first thought was to mount it to my belt and use a long cable extension, then maybe put an inline switch so I could hold the value and not accidentally hit the box with my hand. Given I am an electrical engineer, I will be looking at solutions for optimizing the setup / reducing the footprint.

One thing I wondered with the FS100 is if I could redesign the housing and put it into the place holder for the flash drive. That would be REALLY nice.

All that said, I will have a review soon on working with it!
 
Thanks for the update, Rick! Glad to know you can actually get one now. How much was the adapter before shipping? Also, do you know how much they charge just for the adapter (minus the box) portion? That's if I want to add on a micro 4/3 adapter.

Looking forward to the review!
 
I think the shipping was 40 pounds. If you watch the video above, the prices are given for the box and the adapter separately an those prices were exactly what I was quoted.
 
I just got my MTS EOS adapter for Canon lenses. The box has 3 mounting 3/8-16 tapped holes which easily adapts to mount to my rail system. The box powers the optical stabilization system on the Canon EOS lens. This is really great!!
