Daves, derz a sweet spot somewhere along the zoom lens (but you have to find it cuz I do not know your camera) and check you mail more often.

Damn, damn, damn !!!

Im checking my mail everyday... but... Im getting tons of spam, so I usually take all 100 english written messages and drop it every day... Appologies, but your was probably one of them... Can you PLEASE (please excuse...) resend me all you posted to me ??? So sorry, so angry to myself... pitty spam...

The email I send does not show here, so... it may be my fault.
Get the camera close to GG and then zoom-in (a bit)
Anyway... my son will be there (Prague) in a day or two singing at the cathedral... if you have a few hours, maybe you stop on by and give him a short city tour (if you can) His name is Andrei. If you can, I'll pass you the day, hour and place where they'll be.

Looks like my emails take a "de-tour" to reach destination... I have registered on your site and sent you a message. I am not sure though for is all in Czech....
How do I get to send a message on your site (like we do it here)?

Daves,
I can not say in words how much I like it! You are the first one (I know of) to reproduce the moving Fresnel.
If instead of the "hard mount" you have now you would use some rubber, you might end up with less than linear motion (elliptical) which would be better. At least the movement is PLANE !!!! and this is a huge plus.
Very good.

Thank you... this shots are from old version of mechanism I made last weekend. You know it... its working (some way), but it can not be used :/ because of many problems...

This time we are working on new one, circular, producing less vibration, less noise, certain running... We have first assembly done, but the motor axle is wrong set up and we have some Z axis movement. Hope we fix it soon.

Daves Spi

Looks like monolog, but I'm so happy our next motion mechanism is working :)
Hope it will work with GG attached and will be able to post some video...

Maybe does not look, but its calibrated so if you hold it in hand, you almost do not feel any vibrations. Also the noise is just the noise of motor...

It's very hard to tell from the images what it is, or how it works. Is it noisy?

Hey Dan, when you said 'I can not say in words how much I like it! You are the first one (I know of) to reproduce the moving Fresnel.' - do you mean besides yourself? It was a little confusing to me what you meant by that statement! I thought you were using a Beattie/Maxwell focusing screen (or maybe they are the same thing?)

Dan Diaconu
May 26th, 2005, 11:22 PM
Truck=Fresnel (a certain type of car/screen....)
Ford = Beattie /Maxwell (the brand)

It's very hard to tell from the images what it is, or how it works. Is it noisy?lol, its true. You can get serious injure if you put you fingers to close...
Its calibrated, so when you hold it in hand, you feel just very small vibrations. The part moving in eccentric circle is very light. Hope with attached GG it will be under 20g. The noise is little bit more then the noise of motor.
In fact we didnt attach GG to it yet, but seems to be working. I will complete it and test it tonight.

At the beginning there was a dream. It turned into an idea, then the ambition and hard work turned the idea into reality....I hope this time we are REALLY there :)

Please go to your control panel and enable the email, so I can email you from here. Is just difficult to send you messages on your site (and I forgot the password)
BTW, this mechanism... is it cheap on gas? Can you cut trees? (oh well.... you know me.... (;-)<

(;-)<Consumption is about 6-12/100 (Volts/km) lol, Well - I do not know If I can cut trees, but grass absolutely (rotf). Who cares... Our first mechanism can be used as vibrator for women, this one maybe end up as grass cutter :))) You know... sometimes you are building something and at the end you will find, you are in fact building something else than you thought it is at the begining :)))

Circular motion 0.6mm, powered by 3-6V on 50-100mA. Works with shutter 50,100 and 125. On very high speed works even with 1000 well, but I guess the motor will die soon :)

Anyone anytime thinking about how good resolution you can take from 35mm adapters ? Where is the limits ? Are there any ?

Ok... today I tried to answer myself... The pictures bellow are extremly dangerous... Resolution is 2288x1728, 90% Jpegs, taken with Takumar at 70-200 iris set to 4, Camera shutter was 1/50, iris 1.7, gain 0.

Wow. very impressive. Especially since it's so small. I'm almost depressed now since I'm working on a pulley method like your earlier attempt. :O

Great work. Wish we could see the device or at least learn the premise of how you are achieving that motion from the motor with few moving parts.

Cool,
Dana

EDIT:

This is one of last footage for dvinfo... I think, you can see huge progress till start of this thread...

I will probably film some models this week and make some music clip as final celebration, so if it will happen, I will post it here.

Good luck to everyone with waxing, rotating, oscilating, scratching or whatever to get 35mm image. Wish you your adapter fills your idea and meets you requirements...

I have to move forward to next milestone...

Daves Spi
June 14th, 2005, 03:06 PM
Everyone is hunting some Fstops or what... I do not know how to count the right number, but I've tried this :

I choosed white calendar as testing scene. I always shoot just the whole calendar, no more, no less...

With adapter:
Primary lens Takumar at 70mm set to F4 iris, AE showed F3.2 on camcorder

Without adapter:
AE showed F4 on camcorder

How to count right numbers ? Radek, can you help me ? Thanks...

Oscar Spierenburg
June 14th, 2005, 05:15 PM
What I did is let the camcorder auto expose (or something like that) and see ho many F stops it is. Than shoot the same thing with the adapter at open aperture, auto expose the DV and see ho may stops it needs now. Am I right?
Your footage seem to have a lot of light...2 stops?

Dan Diaconu
June 14th, 2005, 06:14 PM
(for all testing, camcorder @1/60):
If the camcorder "reads" in AE say... 4 (iris) for a certain scene, than with the converter (and lens wide open-which ideally should be 1.2, hehehe....) close the iris on the SLR lens till the camcorder "reads" again 4. If the SLR has a 1.4 (as max), the camera should have at least the same reading through the Fresnel and the lens @1.4 as all by itself.
Daves, if you only lose 1/2 stop due to max 4 on your Takumar, imagine how sweet life would be using a brighter lens...........

Leo Mandy
June 14th, 2005, 06:53 PM
So when you say the camcorder - you mean the camcorder without anything at all, right?

Daves Spi
June 15th, 2005, 01:23 AM
Daves, if you only lose 1/2 stop due to max 4 on your Takumar, imagine how sweet life would be using a brighter lens...........I can test it on 50mm with F2... So no matter how much mm is the lens (if I keep same scene in viewfinder) ? I do not understand exactly :(
I am surprised, that I got same scene at F4 without and F3.2 with. What about the F4 of takumar ? Where is this number ? I expect something like this : If I have F11 by naked camera, I should have F11-F4(of takumar)-F?(by convertor)=~F6 ;-) I know its probably rubish, but I do no know too much lens... But there must be something about the takumars F4, right ?
F-stops means what ? Count of the stops between two Iris setups, or the result after subtraction between them ?

Dan Diaconu
June 15th, 2005, 09:27 AM
Your lens iris (Takumar or anything else) will limit the amount of light that reaches the screen thus camcorder's lens. The brighter the lens you use (2 or even brighter like 1.4) the more light will end up on the screen and be captured by camcorder.
Do this test:
Set the iris on that 50mm at 8 and take a reading on the camcorder. Let's say the camcorder reads 2. Now, open the iris at 2 (on the SLR) and take another reading. it should proportionally close down and give you a reading of about 8.
Between each stop (from 4 to 5.6, from 11 to 16 and so on...) the light doubles (up or down) on both lenses (SLR and camcorder) So when you open one lens one stop you allow TWICE the light through the lens, so... the other lens will close down one stop (to compensate and give you the same amount of light)
Now, if you make available A LOT OF LIGHT (to begin with) using a FAST lens (Max aperture 1.4) then you can shoot scenes at nigh without any problems...
Look at this lens:
http://www.azfoto.cz/_web/_muzeum/leitz/foto/noctilux_1_%5B1024x768_lens%5D.jpg
and what it does:
http://www.alaska.net/~rowlett/noctilux.htm
Goggle for "noctilux" if you want more, but...do not search for price (or you might get depressed)

Oscar Spierenburg
June 15th, 2005, 10:20 AM
I got a 1.4 in stead of 1.7 for my wax-adapter. It's very rewarding to get as much light as possible.

Yes, but I am still mising the point :(

OK... I did this - I took Takumar 1:4 at 70mm and get this numbers :

Camera : Takumar
F11 : F4
F11 : F5.6
F6.8 : F8
F4.8 : F11
F2.8 : F16
F2.4 : F22
F1.6 : F32

But if we are talking about "loosing some F-stops", how do I get this number ?

Just to compare naked camere against camera with 35mm make me sense... What I do not understand is, how can I loose 0.5 Fstop, when I'm using F4 in front of... Hm... going in circles aroun the right point of sense :/
