The only versions of theses lenses I have seen have had standard 1/2" B4 type Sony mounts. I have seen them used on Sony DSR-300, 370, 390 series cameras. These lenses had a standard 12pin connector cable.
By rights these lenses should fit an EX with the supplied 1/2" to EX adapter but then the issue of powering the lenses arises. The only EX adapter I know of that has a 12 pin connecter to power a lens and give the operator full servo control is the Fujinon ACM-21 but this is a 2/3" inch to EX adapter and far from cheap.
To the best of my knowledge there was never a dual hot-shoe version of these lenses. These Canons would now date back to the early - mid nineties. They were classed as a broadcast grade lens back then. Very nice pictures. I think if you speak to Canon today you will find that they will still service them but that there is no longer any parts support should any specific to this model parts be needed.
Yes be careful of that because the Sony and Panasonic 1/2" mounts are TOTALLY different! Look similar until you get them side by side. I have heard about and seen these D tap to 12 pin power cables on various sites but have no idea as to how sucessfully they work. From what I understand is that they give you servo power for the zoom but all your iris functions are manual and no return button fuction. No big loss there as manual is the way most of us would work with the iris anyway. Post back if you try this route as I think a few of us might be interested as to how this would work.
Just some thoughts. This lens if it is a Sony mount version would fit on a PMW-320. A camera I much prefer to the EX3. If you can go the price difference that would be my pick in this range of ½” cameras. Basically the same chips and 35-mbit codec as the EX3 but two more audio tracks, SD capability as well as HD plus a host of other features. It also has the more familiar PDW type of scene file menu set-up as opposed to the more basic 'Picture Profile' approach of the EX series.
The 320 is much more like a PDW series cameras in many ways but file based not disc based but with the advantage of being much lighter. Being a shoulder mount camera I find it much easier to use for run-n-gun type work. That Canon is a pretty heavy little lens and it would make an EX3 very nose heavy which is another thing to consider for hand-held work. The 320 also uses 'V' mount batteries which are pretty standard items. A decent V mount battery on a 320 would balance that lens up pretty well.
Even though that Canon is an SD lens, near top of the Canon range in its time, It should give you pretty decent results. Either way both cameras can put out beautiful pictures if set up correctly.
It's an 1/2 lens and the body is also 1/2 inch. That doesn't mean it fits. It depends on the lens mount, if it's a standard mount or a sony mount. I don't know how you can see the difference. If the lens doens't have a cable, it probably is a sony mount. If it has a cable it can be both. (notice the word 'probably', i am not sure).
The lens number somehow can give you the answer.
