New SG35 DVX Grabs

Aaron Koolen · February 13th, 2006, 06:26 PM

Thanks Daniel. Are you saying that the camera and the unit aren't threaded together, they just sit against each other? Just curious.

Once you've got the things calibrated OK, would you think that steady cam shots, or handheld stuff would be an issue, or once it's lined up can you give it a reasonable amount of movement safely?

I'll probably throw more questions your way as I discover things I need to ask.

Thanks
Aaron

Aaron,
Yes the reason for this design was so that the user could fine adjust the centre of the 35mm frame to the centre of the LCD. However in practise, as Dan has found out, this can be a little unpractical. I have changed this and shipped of 2 units with a firm connection between the camcorder and the SG.

Also, the use of shims will be used very soon to adjust the camcorders height.

Ok here's some full res grabs. Just pulled them off my timeline with 85% jpeg quality.

As you can see the side of the adapter is in shot in almost all of these.. We were monitoring the footage in overscan which was a bit of a blunder. Wayne's new sliding plate mechanism will help you setup the cam properly and hopefully keep it in position. Enlarging the clips by 5% gets rid of the edge. No CC has been done on any of the grabs you've seen. I'll be doing that last after I've dabbled with shake to replace most of the overcast skies.

The images look sharper on my tv for some reason. Maybe its something to do with resolution. My unit doesnt like 'run and gunning' but with updates to the mount I cant wait to be a bit rougher with this baby. I used a fair amount of tracking which was never a problem.

Video coming soon...

Wayne, why don't you just make the camera mount on your rods height adjustable? No shims that way, and no hassles from other camera makes. The trick then is to make sure your frame is precisely centered in the adapter....but I'm guessing you're quite aware of that.

Dan, I responded to your thread over at dvxuser. Nice grabs..but you need to do some glass cleaning.

Wayne Kinney · February 16th, 2006, 07:55 AM

Dennis, what part do you mean to be adjustable? Dans unit has 4 bolts under the cam plate, to allow the cam to be raised or lowered. Please let me know more about your method.

EDIT: Im guessing your going from the old picture on my webpage, with the vertical rods to adjust the adapter height. This is an old system and now the camera mount adjusts in height. Is this what you meant, Dennis?

Dennis Wood · February 16th, 2006, 01:01 PM

Yes, I was going by the web pics. Having the camera height adjustable is a good thing. Are the shims just to allow some vertical adjustment of the 35mm frame...by changing the cam/adapter angular relationship?

I assumed everybody was mounting using .75mm filter threads, but it sounds like you've moved to that method now too.

Wayne Kinney · February 16th, 2006, 01:15 PM

Dennis,
The shims replace the 4 bolts, and do the same job as the bolts (adjust the cams height) but its a little more solid and looks better. I have been told its the system the M2 uses.

Very nice work! What camera settings did you use to end up with this look?

Steve Madsen · February 20th, 2006, 06:45 PM

Nice work Daniel. Apart from the footage, that's quite a filmic looking kid you've got there.

The main issues were practicalities - It took longer to setup each shot with the gg needing to be re-focused after most moves.

I'm sorry, im having a littel bit of trouble comprehending this sentence. Do you mean that you have to readjust the GG with every camera move or do you have to refocus the relay lens to the GG with every move. could you please elaborate?

Forrest Schultz · February 26th, 2006, 11:13 PM

this might be a dumb question, but why are dust and stratches showing up in the frames. doesnt the SG35 spin. just wondering why those grabs show some dirt. THat is some good lookin footage by the way. very film-like.

Wayne Kinney · February 27th, 2006, 04:40 AM

Hello,
Basically, Dans unit did not have a sliding plate, so the dvx would shift slightly from time to time. The sliding plate is a standard item on all new units.

As for the dirt, the ground glass is spinning, however the condenser lens is not, and some dirt has crept in onto that lens. The lens can be removed easily and cleaned.

Forrest Schultz · February 27th, 2006, 08:25 AM

ah. i see it now. thanks Wayne, and good work Daniel.

Aaron Koolen · March 9th, 2006, 02:23 AM

Gonna bump this thread again if you don't mind. Does anyone have any full res footage at high quality (Even only a few seconds) that I could download (I can give you an ftp location if you need it) I'd like to see what the adapter produces but on some non web compressed footage.

Cheers
Aaron
