Decided to do a few simple tests on my HV20 using the various lenses I have for my SLR.

Kit:
Canon HV20
Cinevate Brevis CF1 Kit
Custom made rails

Lenses:
Canon 100-400 f4.5-5.6 L
Canon 135 f2 L
Canon 85 f1.8
Tomioka 50 f1.2
Canon 28 f1.8
Canon 17-40 f4 L
Sigma 8 f3.5 II
Lensbaby 3G

It's apparent that I will have to make a telephoto lens brace considering the size of the 100-400. I would like to try this lens at some outdoor sporting events and see how it works.

    Do you sell your custom rails and support?

    Hi Joe,

    No, I do not sell the rails system. In fact, I just replaced it with the rail system that Cinevate sells. It's much easier to setup and swap lenses with, and it's black.

    does the Canon 100-400 f4.5-5.6 L have fixed focus or you have to correct focus when u zoom out?

    No, it is autofocus or manual focus via the focus ring.

    Which adapter are you using, the brevis? I'm lookingf for a rail system to work with a Twoneil adapter.

    Also what tripod head to you have and would you recommend it? I have the same model manfrotto tripod looking for a video head under $100.

    I guess EF users are stuck with the wide open aperture of our lenses due to electronic f/stop.
    Thanks for sharing info!

    Some very informative tests byond the standard 50mm / 1.8 standard tests for most DOFs Thanks for his Torin.

    Its interesting to see the problem of vignetting at 400mm. The 135mm is surprisingly usable

    Thanks for sharing. I also have a 100-400mm and have been looking to find if someone else tried this setup before. Good to know its performance is actually not bad even in indoor lighting.. except for the visible vignetting..

    Did u get a chance to shoot with this setup in outdoors ?
