HV20 Upside Down with Letus35a Avoids Edit Flip at DVinfo.net

Chris Barcellos · April 13th, 2007, 08:06 PM

One of the reasons I got the HV20, is I thought it my be easy to construct a mount to turn it over, to shoot with an adapter. In doing so, you avoid the need to flip in edit.

I contructed a prototype from a $10 strip of aluminum, and $5 worth of other material, and came up with my first attempt which seems to worki out pretty good. See the photo below.

Expect to mount a monitor on top, and my Beachtek adapter on back.

What if you need to adjust camera settings?

Chris Barcellos · April 14th, 2007, 12:15 AM

Very easy access the way it is set up. Toggle is accessible, as well as menu button. Everything is on screen.

Chris Barcellos · April 14th, 2007, 12:27 AM

Here is a test shot with the newmount. Sure seems like quality is better when you don't have to flip first.

I am seeing a problem with "vibrating" reds with this camera and letus. See the toy car behind the girl.

Chris, did you have to cut and bend that aluminum yourself or is there a shop that can do it for you?

Chris - perhaps I'm not clear: are you attributing the problem to flipping the camera? Does it not do this when the camera isn't flipped?

Being new to whole 35mm adapter thing, are there any out there that don't flip the image?

Rafael Lopes · April 14th, 2007, 09:10 AM

Hahaha. I love these pictures of the HV20 with 35mm adapters. Most of the time the adapters are actually bigger than the HV20. I'm downloading the footage right now (if it's anything like other HV20+35mm adapter footage I've it's a winner for sure...this camera is amazing with adapters!)

Just brute force and ingnorance.

Got the aluminun strip at Home Depot. Its 2 inches by 3ft, I think. About 1/8 or less thick.

I just hand bent it, and cut as needed. the part on top was done in bench vice. the other bends were done by force against an edge. For instance on top of a table, with a portion hanging over. (I actually had a a divice I built for a "steady cam" that I slip this into to get a bending angle, but that was just a convenient tool....)

Note: I extended the bottom piece by bolting together two pieces after the fact. I had originally had another idea, and cut it too short. So my next version won't be two pieces on the bottom.

No, I just mentioned the red issue to explain it, it happens either way. I have started a thread on it to see if any one else has seen it.

Brad Vaughan · April 14th, 2007, 11:11 AM

Now that is very cool and the footage is 1st rate!

Now, I'm completely interested in this Letus35a.

So it appears in the picture you have an additional lens (Nikon?). What does the Letus do for you in terms of added features? Depth of Field?...can you zoom better with this as well compared to the built in 10x range?

I'm new to this video world, but I'm already very addicted and would love to get shots like this.

Chris Barcellos · April 14th, 2007, 11:30 AM

Hey Brad:

Go to the alternative imaging section of this forum and look at all the adapters. They are all based on using a video camera to capture an image from a ground glass that is itself produced by the 35mm lens, taking advange of the depth of field characeristic of the lens and 35mm format. All the adapters involve methods of improving image to make it usable. Generally, they involve a vibrating or spinning ground glass, to eliminate imperfections of the screen. Google Brevis, Letus35, SGPro, Redrock M2, Mini35 for starters.

Brad Vaughan · April 14th, 2007, 11:39 AM

Will do.

Thanks for the direction.

Dennis Vogel · April 14th, 2007, 02:40 PM

I sure don't see any vibrating reds. I don't see them in the T ball clip in this thread either: http://www.dvinfo.net/conf/showthread.php?t=91471

Maybe I should be happy that my eyes don't see the stuff that some of you are seeing.

Good luck.

Dennis

Hmmm. I wondered if it had something to do with my monitors, both LCD.
Are you using LCD. See this thread for others discussiong it. I also posted a red bucket short clip there.

Hi Chris -
Saw the vibrating bucket loud and clear - 24" Dell LCD's - looked like the reds were oversaturated or something? Isn't red always a tough color to get "right"? I seem to recall something about not wearing bright reds in studio situations...
