Confirmation: Do you need Macro lens for adapter?! at DVinfo.net

Goh Iromoto · February 12th, 2005, 11:12 PM

hey guys,

I just need confirmation on something.

Do you need a Macro lens for the 35mm adapter, IF my camera lens is only 43mm (panasonic GS-400).

I asked on a thread before and someone said NO. However, I have completed my version of the Agus (rotating CD) and the image seems too small...so I'm assuming i need a macro. I'm hoping that maybe someone can tell me a method though. (So far I just put the cam as close as possible, and zoom in as much w/o blur...the image on the gg seems small?!)

I've followed every instruction/advice on the forums and website (mediachance), and have a focused image on the gg. I am also using Nikon AF lens.

Also, would a PCX/DCX lens take the role of a macro lens? I'm thinking of getting one of those instead since they seem to dissipate hotspots, etc.

Appreciate any input, thanks.

looks like there no need for that on GS200. Try the camcorder's lens 4-5" away from the GG and zoom-in, see what happens. You should get a sharp image. If it does not fill the screen, try a +3 or +4 CU lens. Good luck.

thanks,

btw, whats a cu lens? condenser?

thanks.

ps..also i have gs-400....gs-200 has 37mm lens...if this makes a difference

Dan Diaconu · February 13th, 2005, 01:32 AM

CU=close up.
only CU size (37 vs 43) Get what you can find and step up/down rings.

I just ordered a 7+ 10+ macro yesterday for my PV-DV852 from Panasonic. I found that I could not get rid of vinetting without using a macro. But if others have done so on the GS200, I can't see how the GS400 would be any different, consider it is the next step-up model.

Daves Spi · February 13th, 2005, 10:15 AM

I have GS400 and macro lens are needed. When you draw 24x18mm rectangle, you get it full when you place paper straight on cameras lens :) The sharpest & closest image you get when zoom change from 2x to 3x. This is the point, where you can get sharpes image on very close objects.

I broke some old Pentacon 135 lens and use first as macro lens. Has no aberation or other artifacts. Works cool.

Leo Mandy · February 13th, 2005, 10:20 AM

Ok, are you saying that 7+ is going to be too much?

Aaron Shaw · February 13th, 2005, 10:29 AM

That entirely depends on the camera :)

Leo Mandy · February 13th, 2005, 10:57 AM

The store that I am ordering it from has both a 1+2+4+ Hoya adapter kit and he is ordering me a 7+ 10+ kit as well. I will have to test both and see.

Dan Diaconu · February 13th, 2005, 11:50 AM

Save your money. I have +1, +2, +4 and +10.
Use none for GS200. Most you may need is +4 (on GS400 IF EVER)
Keep a GG/SLR lens infront of your eye (close) Major vignet!!!
Take them 1 foot away.... see the dif?
Try the GG further away from the lens to get ridd of vig and zoom-in. Use CU only if anything else fails.
Your problem is the small image 18/24.

Leo Mandy · February 13th, 2005, 12:13 PM

I've got the PV-DV852 Panasonic, so I don't know how it compares with the others. It is about 2.5 years old, but I got it last year on a close-out sale at B&H.

I don't know how feasible having the camera 1 foot away from the GG is when making this device - it would elongate it quite a bit, BUT I know what you are saying. Right now it is about 5-6 inches away from the GG and I still need to zoom in - but I can't zoom in far enough without it blurring, so I need the Macro.

Also, are people just using the Fresnel pieces to get rid of the Hot-spots? Does this go between the DV camera and the GG?

ACTION >> GG >> Fresnel >> Macro/DV camera

Thanks

Dan Diaconu · February 13th, 2005, 12:48 PM

Fresnel IS the GG. Focusing screen as in SLR cameras. That solves the vigneting (hot spot) and you can get a 24/36mm clean and clear image. See http://dandiaconu.com/gallery/Brightnes-tests
for details and watch the first two clips!
A bigger (than what you have now) screen may not need that much zoom-in and may work without CU.

Leo Mandy · February 13th, 2005, 01:37 PM

Ok, but I am using a Spinning CD. I don't know how to get a bigger/larger circumference spinning CD than the production ones. Is that what you are talking about?

Dan Diaconu · February 13th, 2005, 02:57 PM

No.
a CD will limit your frame size to what you have. No bigger, no brighter. Even a 2X supersized CD would not give you a brighter (and bigger) picture. Is just a spinning GG.

Goh Iromoto · February 13th, 2005, 07:56 PM

thanks guys,

will look into getting a macro then...seems like +10 would be way too much.

Mandy, curious to see which Macros worked best for you.

Also, still curious about DCX/PCX lenses...what exactly do they do?

Would I still need one if I get a macro? Or would they act as a type of macro...do they have magnifying properties?

thanks,

Goh
