Hi, There are only a few c-mount cosmicar lenses are designed to be used in sensors of 2 "and 1" that are compatible with the beaulieu 4008.

You have to be aware that they have to be of standard c-mount and not c-mount to cctv, because the back focus goes far of 1mm beyond the rear ring and not enter in the body of the camera.

After this all they have to do the Collimation (how to: http://lavender.fortunecity.com/lavender/569/lenscollimation.html ) to your camera with a brass spacer rings

fit for that purpose and they are put in back into the rear thread to achieve infinity focus.

( this rings you can get here: http://www.edmundoptics.com/onlinecatalog/displayproduct.cfm?productid=2012 )

The lenses compatible with beaulieu are those marked with the red circle in the pictures below.

All the others are not because the backfocus goes back far beyond the rear ring and does not allow infinity focus.

For a rare 16mm lens I've found

that just came out from behind 1mm screw back, I had to make a small change in the ring of the lens fix on the camera.

I had to remove the small black ring inside the lens mounting ring as the pictures show

,and so allows infinity focus without hitting anything inside the camera, just like the others I have to put the ring in the back screw to get the infinity focus.

The lens:

This is compatible a backfocus

With this backfocus is not compatible

Hi, I think this is what you seek, but a bit pricey;

Hi,Thank you for the excellent explanation, this time resulted only taking the lens and making the focus on the GG, yesterday did not work very well also because of after the 14h of work in studio and have my eyes so tired that already blurred for they belonged.:)

Best regards

Hi, Also I do not understand how it is not in focus, but actually to be in focus I have to make new adjust in the ring of the viewfinder.

I did the texte with a focus card to 3mt from de lens and focus on the lens to 3mt.

will be likely that some element inside the viewfinder moved from side, or will be by my eyes diopters that makes that difference?

Anyway I always must set by Ground Glass.

Thanks

Regards

Now I am having trouble tuning and focusing diopter of the viewfinder, my eyes are not as new, and am already with 1.75 diopters, the problem is that, when setting the focus and the viewfinder diopter with Ground Glass I see all well focused, but when remove the Ground Glass it all slightly blurry, my doubt is what will make the proper focus, tune to my eyes with or without the Ground Glass? what will it be the real focus?

Hi, Thanks for the excellent describe.

Regards

Hi, Where you place this target to pitch, in front of the gate without a lens?

Great work.

Hi,apparently there is no physical problem of fitting the lens, but when working with very closed f-stop do not noticeable but when I work with it fully open apparently is out of focus, and the solution according to experiments that did is unscrew 1/4 turn of the screw to get focused fine.

Then I think I have to add a washer on the threads of a certain thickness to that screw least 1/4 back.

Does anyone know anything of this situation or have a similar solution?

Regards

Jorge

Hi, cosmicar i think you'll find is a c-mount cctv lens with manual aperature, designed for use with cctv/security cameras. Possibly ok optically around f5.6, forget it around f2.0.

 

Sorry I am disagree here: I have tested fully the 12.5mm/f1.4 Cosmicar/Pentax lens to my RX5 super16 and I can tell you that it's absolutely sharp even at full open!! This lens is, with the Kinoptiks 5.7mm and 9mm (A-Cam) and the Cooke Kinetal 12.5mm (rare en c-mount), the only wide angles c-mount that I know which cover plenty the super16 area, because it was designed for the old 1" tube video cameras. Next week I am going to test the Computar 12.5mm/f1.3 lens, also a 1" TV lens. These lenses are selling in ebay by insignificant bucks... (I am not the seller)

 

If you intend to use such a lens on a beaulieu/bolex be carefull the c-mount thread is longer than switar,angenieux and schneider primes. May force the turret away from the camera body.

 

The Cosmicar 12.5mm doesn't have this problem. It's posible to use it at infinite (shortest distance to the gate) moving the turret.

 

All the best

 

 

 

Hi, Sorry but I had to lift this old post, I bought a cosmic 6mm to use in a beaulieu 4008 ZM4, just as you said I think I have to turn the screw to have the sharp focus, does anyone know how many laps have to take to stay back with the correct focus? I think with the experience that I did get 1 / 4 back less.

But watch out for unwanted reflections can occur erroneous readings, since there is not a flat surface and uniform.

The problem is Stand-Ins don't just stand... they move.

It is, the problem is that the actors move on the set, and so have had to make several heads,:) :rolleyes: , but the idea of the new card 18% is funny.

Two or three successfully. When Kodak discontinued 4X they recommended pushing Tri-X as a replacement.

Thanks Jim.

Thanks Chris.

How many stops can I force the reversal Tri x?

Tri-X reversal?

Yes, reversal.

And force with a resolution aceptable.!!!

How many stops can I force the Tri x?

1. A screw is under the serial number plate.

2. Threaded collar under the eyepiece (needs a pair of long nose sharp pointed pliers). For easy access unscrew the plastic eyecup first.

Thanks Laszlo

Here I leave an example, which I'm using a HMI for the two functions, to the trees behind and to the actors backlight.

For plans in general can leave only the light from the flashlight of the players that is almost in silhouette but is ok

May I suggest as I did at times in an identical use of a Chinese lantern hanging on the tip of a cane and then the players with an assistant when the ballon beneath the level of the chest, and let the HMIS for funds of the garden, taking place on the back for the trees.

The lamps and the power to use within the balloon will always be according to the sensitivity of the film because may need more f stop to print, that is used taking into account that if the tungsten can not pass the torch of max, you may choose the cold light lamps that allow more power and less heat and then correct or not.
