Ok Robert - I took your advice and ordered the Letus Extreme this week directly from Zacuto with the Z rail Adapter and 4" rods. I already own the Zacuto baseplate and 12" rods. The Zacuto Follow Focus is still out of my budget but at least I know which direction to head when the time comes. Thanks for your help.

Let us (no pun intended) know how you like the rig!

just realized someone was using this thread to make buying decisions and just wanted to chime in. I get antsy when I see people making claims on the forums about which is adapter is way better than the others because i've owned a lot of them.

Leaving the Letus Ultimate aside which I haven't seen yet but is significantly more expensive ( though it sounds killer.) - I don't think there is a clear ranking between the Letus Extreme, the SGPro and the Brevis.

They all have pros and cons which have been described elsewhere in great detail. I own all three and have also owned a Redrock. The build quality in my opinion is equal between those three. The Letus looks like its build quality is greater but my experience is they are about the same. If anything the SG seems to have fewer complaints but that may be because its a spinner. I wasn't impressed with the Redrock design as much but it seems to have been improved by the flip addition and many people like its more diffused look.

Of the pro's and cons - The Brevis is fastest in low light with f 2.8 lenses. The SG probably has the prettiest look but loses more light, and the Extreme falls in between the 2. All are reasonably fast compared to the Redrock and all 4 look much better with their flip adapter.

They are also all works in progress and changing everyday.

Lenny - which has the least f-stop loss? This is very important for someone who is buying it for use with an HV20/30.

he claims the brevis35 does. If you go with the brevis I'd recommend getting it with the flip adapter. It really improves edge sharpness and reduces CA.
