Top of the shoulder pad is approx 52mm from the end of the rods - bottom of shoulder pad approx 35mm from end of rods - if that makes sense?

Yes Mark it does, thanks.

Its been a little while since my last post... We have been working hard on the EXMount and are underway with a production run of mounts.

The website - EXMount - Custom shoulder & Tripod mount for PMW-EX3 cameras - has been updated with more pictures, information and pricing.

We expect this run of mounts to be completed within the next 2 weeks.

Check the website and email or post here if you have any questions etc.

The EXMounts are now available - check the website for more details - EXMount.com.

We're now working on some accessories to enhance the EXMount further - more info to come on those.

Hi Mark,

Nice work. In an earlier post, you mention that you were looking at using it with an EX1.

Have you done any further testing with it?

What are your thoughts/concerns?

Do you have any available at the current time?

Regards,

Tom Chaney

Hi Tom,

We've been busy getting the EXMount for the EX-3 sorted. But I am being constantly asked about the EX-1/1R (and now the Panasonic AF100 and the new Canon cameras).

The main concern with using the EX1 on the mount is that there is only the 1 1/4" mounting point - so the weight of the mount and accessories is on that 1/4" plate on the bottom of the camera - which is held on by those 4 relatively small screws.

But there are a couple of options that we can look at to reduce the load on that plate. Will see if I can get hold of a camera shortly so that we can have a proper look at it.

As far as availability goes - we have stock of the EXMount for the EX3 available now.

Thanks,

Mark

Hi Mark,

Thanks for the reply. You really have done an excellent job with this design.

I grabbed my camera and I can see your concern about the four screws.

However, isn't that a concern for any mount on the EX1.

What options can we look at?

Also, what Chrosziel do you have attached, and what follow focus system have you used with your design?

Sorry for all the questions, but I am looking for a solution and yours seems to be the best.

Regards,

Tom Chaney

Hi Tom,

I can't speak for other mounts specifically, but unless there are other mounting points on the EX1, any mount that uses just the 1/4" thread will have the same issue - any load goes onto those four tiny screws holding the plate to the bottom of the camera.

At least with the EX-3 we have the extra 2 mounting points on the angled part at the back of the camera - so the load is spread.

My concern with the EX1 on the EXMount is the extra weight of large camera batteries, radio mic receivers, nanoflash etc - which are all attached to the EXMount - will put a lot of strain on the screws holding that plate onto the bottom of the camera - especially if everything is carried by the camera handle.

So we need to put that load back onto the mount (which is pretty tough). I have a couple of thoughts on this - so will look into it and see if we can come up with a workable solution. I have been asked numerous times now if it will be possible to use the EXMount with the EX1/1R - so its probably worth doing!

I'm using a Chrosziel 450 EX-3 kit - with Petroff rod holder & wedge plate. The Petroff works well as it has a good vertical range for positioning the mattbox. Some of the photos show a larger Chrosziel mattbox which I generally use on the bigger cameras (700/350 etc).

The follow focus unit is a Cavision.

Mark
