Wondering if anyone has any experience with the Dana Dolly Junior?

I am looking to mount a short "Riser" to be used with

HDR FX 1, Manfrotto 501 HDV .75mm ball

wondering if the camera is too big? The weight is fine ....

Do the anti-tip brackets work on the Junior

I have tried contacting them and get no response, are they even in business still?

They are very much still in business. It is a small team of two, so they usually only reply to emails. The NAB show and the upcoming CineExpo show have probably taken all of their time. I have not used the Junior, just the Original Dana Dolly and the new version.

Please check with FILMTOOLs about the setups with the Junior. they are a dealer for the complete range of product.

Hope this helps
