Any luck putting a 35mm lens adaptor on the V1u?

[Heath McKnight]

Okay, what are the options for 35mm lens adaptors?

1. Redrock Micro (www.redrockmicro.com).

2. P+S Technik (pstechnik.de/en/index.php).

3. Cinevate (www.cinevate.com).

Any others? And please provide links.

Also can you use other mattebox systems?

Adapters ALWAYS invert the image. It is a function of physics and lenses. All lenses invert images. Your eyeballs do it. Your camera does it. The chips in your camera are essentially upside down to correct the inversion. Some adapters have an extra device that re-inverts the image, but that adds more things in the light path so there is less light and more places to get dust.

The Brevis uses standard rail systems, so any mattebox should work.

I believe the follow focus is in development at the beta prototype stage. Go to the cinevate forums for more information.

Just building this:

Home made 35mm DOF box.

Uses pretty much home-found parts except for a 72mm Redrock HD achromat which I've got on a 62/72mm step-up ring at the moment.

(planning in using this box with other cameras with larger lenses as well, otherwise I might well have gone with 52mm)

Uses a standard Cavision 15mm rod system.

That's my Chroszeil 4x4 matte box off my 16mm camera up front.
Beachtek 8 and Varizoom monitor battery sitting on top of the DOFbox until I find a better home for them.

Nikon primes for the moment. Maybe 35mm movie primes later on, we'll see how this goes.

The Varizoom 7" monitor up top does the unflipping and reversing.

Love this camera!

Hi folks I have a SGPro R2 on my V1E with Canon FD lenses. The one on this picture is a 135mm F2 lens its great, I love this thing. I have a cheap Indian Mattebox now so I will take another picture with it on the rig looks great, just need my FF now.

I recently traveled to Cambodia for my church and took a V1U, Letus35 flip(http://www.adapterplace.com/), and a canon eos 85mm. I have the low rez video available at www.wampictures.com, first video on the left, if you want to see what it looks like go there. (shot in 1080 60i and edited in 480 60i)

My opinion: The advantage of the letus35 flip is that it flips the image so you dont have to do that in post. Plus as I was shooting, it was nice not to figure out a way to see it right side up (since most 35 adapters record it upside down). I did a lot of shooting from the hip and all hand held. I could just screw the adapter on, add the lens, adjust the camera settings, and i was ready to shoot. In the end, I was impressed that the letus did so well for the price, and allowed me to shoot amazing video! That's my experience, hope that helps.. -wam

Great images. I'm always impressed by the color from the V1. The footage with and without the adapter mixes nicely.

Hi again, I know most of you guys are from accross the pond but the SGPro R3 is really worth a look, check out the home page and watch the test vids, the light loss is minimal about 1 stop and then the lens you use will also add some loss but go for the the F1.4 or F1.2 primes if you can. I have my system setup on rails and I can switch from 35mm rail system to V1 with its own sun shade and back in about 3 minutes. Most of this time is getting the focal distance and focus on the GG but its very easy, run and gun with the system gets a bit tiresome but most of my work is supported. Its really worth a look and Wayne Kinney has allways been spot on for support and responses.

And no I am not associated with the SGPro or Wayne. Its just a great piece of kit.

Stephen,

For your SGPro, which step-up ring are you using with the V1? Also, how do you manage image flipping?

[Stephen Deboo]

Piotr,

The version of SGPro I have is the R2 with the longer tube and Achromat. It uses a 72mm to 62mm adapter ring that was supplied with the unit. I use FCP to flip the image in Post. But Wayne has a flip adapter he is thinking of developing as an add on, but only if he gets a high enough demand.

[Piotr Wozniacki]

That's interesting, as with the Rev3 it's said on the web page that they don't provide step-up rings for cameras with lens other than 72mm...

[Stephen Deboo]

Piotr,
I must admit I dont remember getting the ring with the adapter but I can't think of anything that I have that it would have come with. I order so much kit off the internet its possible I did get this from a third party company though. Steve

[Piotr Wozniacki]

Forgive my ignorance, but what exactly is the function of the achromat in 35mm setups?

[Stephen Deboo]

It helps get a good focus on the ground glass, some cameras do not require them but even without needing them you get a better result. Wayne explained that the long tube (which is longer than Rev 1) helps obtain the maximum resolution of the imaged help also by the Acromat.
