Re: World's First Electronic EF to NEX Adapter!

My two adapters from Metabones arrived yesterday. Tested on the FS100 with the Canon 24-105mm F4, iris adjustments works perfectly and so does the IS. Will test with other Canon mounts soon. They were delivered 15 days from when I confirmed and paid for my order. The inside wall of the adapter is, as mentioned on some blogs & forums, covered with a black felt cloth type of surface (apparently to prevent reflections from light on the sensor...)
 
Just got my Metabones adapter. Works like a charm!! Works perfectly with my Canon lenses with iris changes and IS and also works fine with my Sigma prime lenses. Awesome product, thank you Conurus!

I'm curious if this adapter will also work with the upcoming FS700......
 
Someone has tested it with the FS700 and it worked.

I received mine and it works great. The only thing I don't like at the moment is my F1.4 bokah is being cropped at the top and bottom because of the inside size.

When my F1.4 lens is fully open and a light is out of focus in the background, the shape of it now is cropped on the top and bottom instead of being a perfect circle. If I use a dump adapter that doesn't restrict the pathway of light hitting the sensor, it's correct.

The problem is, the rectangular hole is blocking light from the back of low F lenses that have wide elements in the back.

Might be time to lose my warranty and see if I can make a better design on the inside. I don't mind moving the circuit board that is probably in there to somewhere else.
 
Wow Rick, that does not sound good at all about the f1.4, considering I have 4 lenses that go to f1.4.

Could you post a picture so we can see what it looks like? Does this problem go away by f 1.8 or so?

How would you make a better design? From the pictures it looks like the rectangular hole is fabricated in there. Sounds like major surgery :(

Thanks for any updates.

I noticed also, and I think it's funny, wierd, but mostly a non issue. with my 35, 40 and 85 1.4, at 2.0, it's not noticable. I rarelly shoot below f2.8 to f4, unless it's very dark and I can't light. and even at 1.4f, the effect is visible only when the out of focus light is WAY out of focus (means, far from the subject) and the light is at the extreme edge of the frame. And even then, you really need to know the issue to notice it.
 
So lets say that you are shooting car lights passing by at night, but very shallow focus so the lights just appear as large, Bokeh circles. Will the circles be cropped at 1.4? Man... that would really suck.

Could one of you guys post a picture of this phenomenon?

I shoot f1.4 fairly often so it will affect me.

Also, it seems the adaptor adds a lot of length to the lens. Does this seem to be a problem with the bigger lenses such as the 24-70 or the 100mm Macro L? Does it need some extra support with the longer lenses, bigger lenses like a collar or something.
 
It dosen't add more lenght than any other EF adapter. If you use heavy lenses, it's a good Idea to support them. I don't think it's need with something in the range of the 24-70.

If the car pass through the frame out of focus, yes the light will be sightly croped at the VERY far edge of the frame. With the movement of the car, I think no one will notice it. I need to finish an edit today, but tomorrow I could post a clip illustrating the behavior.
 
I was doing some highlight testing when I noticed it, but, not shooting something that made sense yet from a cinematography standpoint. Although I will say, I shoot F1.4 alot so it is a concern of mine still. When I get a chance, I will try and snap an image.

After studying the adapter more last night, I think it would be difficult to remove that section even if I move the circuits elsewhere. Impossible? No, but I am not sure I have enough free time at the moment for the major amount of work that would entail.
 
Hey Rick, are you also only getting it only on the very far side of the frame edge like Jean Phillipe? If that's the case, I might be able to live with it. I'm wondering if it's something that might be more pronounced in one metabones adaptor vs. another metabones; as if it were a QC issue?

I also shoot f1.4 semi-regularly, although with the FS series and low light, I might not need to as much.

My use of F1.4 is for DoF relative to the distance of something from the lens, not really for low light with the FS100 :)

I have not tested it through the range. What I saw was in the center of the frame but with a really out of focus super bright LED. It's also relative to where the light source is in relation to the lens, if that makes sense. It was very apparent to me, but, this was NOT something I would have shot, so I need to look at some real situations and where my focus actually sits to see how I feel. Typically I don't have a light source light this in the frame so it was unrealistic.

Given the hole is molded plastic, I am thinking that it should be consistent across their adapters. Even if I do not like the square hole, they still did a great job on the manufacturing to me.
 
well it's a bit tricky but you could just remove the metabones, put a dummy adapter and shoot w that when you need 1.4 ...easy, right? ;)
 
Metabones has released Version II of their Canon EF to Sony NEX adapter. New features include Arca Swiss style quick release, round opening (which means no more cropped bokeh), extra anti-reflection measures, and a power save mode.
