Re: How about the new Heliar 15mm (Cosina) for 360 deg pan ?

[Sofjan@xxxxxxx]

Hi Stan 
    
     It is not my original idea or project . It is actually Those of Mr 
Dusariev and his colleaguae. Of whose Books has been a great help for me.  Mr 
Dusarev sold a compilation of 360 deg panoramic camera construction notes for 
a very reasonable price.  You can also see the Introduction on 
www.panoramic.net 
     My odessy into 360 panoramic started out when i read Robert Erickson 
post on the newsgroup. he offered to show a homemade 360 deg panoramic . I 
was intrigued so i email him and he send back the web site. That was 2 1/2 -3 
years ago.  Took me 3 weeks before i ordered the book from Mr Dusariev. and 
take me a full 1 years to  dream( alot of dreaming), imagine, scrounge and 
obtain parts for my first  360. it has a Tokina 17mm on it.  work Okay. but 
this second one will definetly work much better. 

   Here is some of my  parts source 

   Zeiss folder Nettar  25-40 dollars from  used market . 
   Pulleys i used a  1.25 inch pulleys cost less than 2 dollars each from 
Small parts Inc.  
   Orings   Same above.  
   Motor  i used a 12v gera head motor. i got from maplin  $12-15  
  mine would  give 12.5 rpm with 6 V and 24 Rpm with 12 V 
   Current Jameco  catalog has Alot of new  Gear head motor at the same price 
range.  Jameco motor has less torque but it should be more than enough. 
    And a Leica screw mount retaining rings (5 buck)  My local camera store 
promised to sell it to me for that price when he find it in his junk bin. 

    And of course your choice of wide angle lens.  Tokina 17mm MF seems to be 
cheap enough or if you enjoy new toy like me A 15mm Heliar  should fit the 
bill.  BTW any of the wide angle could do it is just that the negative become 
too long.   
   The formula is  Neg length = Focal length * 2 * 3.1416 
    I try to stay under   4 or 5 inches( 100mm - 125mm). Because i don't 
think that is photofinisher that has a 8x10 enlarger and will print for you 
inexpensively.
Hope this help.

<< Dear Sofjan,
 
 Your project, a homemade 360 pan-camera, sounds very interesting and 
 ambitious. If you ever get the thing built, I hope you will share plans and 
 your sourcelist (like for the gears, etc.).
