MTF Services Ltd MTCONEFF3 overview

  • 1Description

The MTF Services Ltd. MTF EFFECT Canon EF to F3 Mount Lens Adapter is a complement to a separately-sold Canon EF Control Unit developed by MTF. Both the adapter and the Control Unit are a pioneering result of a long time of research and discovery. Together they let you control the aperture of a Canon EF-mount lens on a non-Canon, non-EF camera. They moreover let you open up aperture at much more accurate f-stop increments of 1/8, whereas even on Canon cameras aperture opens in increments of 1/3 only. Furthermore, both of the above factors are achievable even on EF lenses that have image stabilization. All of this has never been possible before, and it allows you to use your Canon lenses without aperture restrictions on non-Canon, non-EF cameras.

Previous to this innovation, using an EF lens on a non-EF camera by means of an EF adapter meant that you'd be stuck with the aperture that was already set on the lens, and that the only way to change the aperture would be by dismounting the lens, attaching it to a Canon camera, adjusting the aperture to what you want it at, and then remounting the lens back onto the non-EF camera, and all over again for every adjustment. This is so because Canon lenses have no manual aperture control and are purely electronic, and because a regular EF adapter only lets you mount an EF lens but isn't capable of transferring any electronic information.

This EFFECT adapter though is a bit different than regular ones. It features an integrated cable for use with the EFFECT Control Unit. The cable plugs into the Control Unit and enables lens control, and the Control Unit has a knob that adjusts aperture. Two other EFFECT adapters are optionally available aside from this one. They are an EF to micro 4/3 and an EF to Sony E.

  • Complements an EFFECT Canon EF Control Unit
  • Controls aperture of EF-mount lenses on non-EF cameras
  • Adjusts aperture in 1/8 f-stop increments
  • Works with lenses that have image stabilization
  • The Control Unit that this adapter is a complement to has successfully been tested with all Canon and Zeiss EF lenses, and successfully with most third party EF lenses, but may not work with -- it may not succeed in controlling the aperture of -- some third-party EF lenses

    MTF Services Ltd MTCONEFF3 reviews

    MTF EFFECT Canon EF to F3 Mount Lens Adapter is rated 3.0 out of 5 by 1.
    Rated 3 out of 5 by from Accurately made, badly designed We have purchased this effect box to allow us to enable our Canon lens' ability to stabilize the lens and change aperture. In this regard the box appears to work SUPERBLY. More tests to follow. But there are a number of design issues that, quite frankly, stupefy us given the amount we spent on the box and the ring 1- the power button is a click-on function with the big fat wheel on the face. This means ANY pressure on the button turns on the power - a very easy thing to do. So storing it is very awkward you have to find a way to ensure the wheel isn't depressed. We are cutting a piece of styrofoam with a hole to slide over it for storage. Awkward, but not critical. Oddly. you have to hold the button down for a few seconds to turn it off. I would have expected the same to turn it on. Just remove the batteries when you're done!, you say? 2- Well, battery replacement requires a tiny philips screwdriver and a tiny screw to open the back door. The screw will be lost soon (somewhere in the grass I predict). But I'm forced to ask, what is wrong with a spring-clip back panel where a simple thumb depression is all that's needed? Even a thumb screw with coin-slot ability would have been prudent here. Something where we don't need a tool to open it! 3- Which brings me to the case. Metal? Heavy metal? Seriously? As if we don't have enough weight with the F5 and all it's gear. If I'm activating a stabilizer, I'm carrying the camera-- I want the weight to be minimal. A composite material would have been a better choice. And a smaller box to boot. 3- since the (non-removable) cable terminates at the adapter end this means it's always hanging off the adapter. I have to swap out my adapter for a standard (dumb) adapter if I want avoid having a useless cable swinging from my camera when not using the box. I really would have preferred to shelf my old MTF 'dumb' adapter all together and leave this adapter on all the time. Ideally it would have been nice if the cable came come off at both ends. Or at least and the adapter end rather than the box end. 4- If it does have to terminate on the box, a 90 degree angle on the cable would seem to make more sense as it would be less in the way and less being prone damage from things hitting it. All-in-all, not very happy with the design of this. Given how much we spent on it and the box (a whole lot!!) I expected a much, much better design. If it doesn't perform well in the next round of tests we may feel the need to return it.
