daniel_iggers Posted March 25, 2006 Share Posted March 25, 2006 I just acquired a Kodak Pony II 35mm viewfinder camera. It is from the late 1950s (say 1958), and has an f/3.9 44 mm Anastar lens (a good quality 4 element lens, I've been told) and a single speed (1/125) shutter. The apertures - from wide open at 3.9 to f/16 or f/22 - are indicated only by an Exposure Value scale that runs from 9.5 (wide open) to 15 (f/22?). There is an exposure guide on a small rectangular card that slides into a holder on the back of the camera. With Kodacolor Film, with Bright sun, sand and snow = exposure value of 14; bright sun = 13; hazy sun = 12; cloudy bright = 11; open shade = 10. What was the asa rating of Kodacolor in 1958? I'm guessing 100, as the little chart than makes sense - for example, a combination of the 1/125 shutter and f/16 for "bright sun, sand, snow" equals EV14. (Or does EV14 = f/22 and EV15 = f/32?? Seems unlikely.) Here is my guess as to the apertures that correspond to the exposure values: EV 15 = f/22 EV 14 = f/16 EV 13 = f/11 EV 12 = f/8 EV 11 = f/5.6 EV 10 = f/4 Does anyone out there have a manual, experience with the Pony II or a better guess?

Rob_the_waste Posted March 25, 2006 Share Posted March 25, 2006 Hi Daniel. I don't have any documentation, but I think you may have come close to answering your own question adequately. I'm using the exposure guide on the back of my Signet 35 (1950). For Plus X (ASA 100), with bright sun, bright subject, the 1/100 shutter speed corresponds with f/11. I'd guess the film speed of the day was either ASA 25 or 50. Link to comment Share on other sites More sharing options...
victorm. Posted March 25, 2006 Share Posted March 25, 2006 According to The Leica Manual, 1965, Kodacolor has an Exposure Index of Daylight 32. The Daylight Exposure Table shows "Bright Sun Strong Shadows" needs f/11 at 1/50 sec. "Bright Sun on Light Sand or Snow" needs f/16 at 1/50 sec. Plugging these numbers into an old Sekonic meter gives EV12 for the first situation and EV13 for the second. Using 1/125 as the shutter speed gives EV14 at f/11 and EV15 at f/16.

kelly_flanigan1 Posted March 25, 2006 Share Posted March 25, 2006 In 1961 Kodacolor was asa 32 in daylight, 20 with Photoflood/3400K with 82A filter, asa 16 with 3200K pro lights and a 82C filter on the camera lens. This is from the Kodak publication E-77; Kodak Color films 4th edition; with a 4-61 data code on the Kodacolor data sheet. the data sheet has an "exposure value" of 13 for bright sun, ie F11 at 1/50 or 1/60 second. <BR><BR>Kodacolor came out in 1942; it had an asa of 25 in 1946, 20 weston, 32 with GE meters.<br><BR>Kodak super panchro-press sports type sheet film was an asa of 250 in 1946; tri-x in sheet an asa of 200. Note that in that era B&W was 10 to 8 times faster than Kodacolor, giving one 3 fstops performance. Link to comment Share on other sites More sharing options...
david_m Posted March 25, 2006 Share Posted March 25, 2006 Its easy to figure out, fully open is F4 (EV 9.5), it proceeds from there in half stops to F22-32 (EV 15). The exposure for hazy sun at 1/125 is always the square root of the film speed. E.g. with 100 asa film, its 8-11 (EV 12). This camera has a fixed 1/60 sec shutter speed so you need one stop smaller aperture (EV 13). This camera was designed when common film speeds were 25-80 asa.

larrydressler Posted March 26, 2006 Share Posted March 26, 2006 David that is the way I would have offered it except for 1 thing. the film was rated slower in those days even at the same speed. I would pull it 1/4 a stop for slides. Larry<div></div> Link to comment Share on other sites More sharing options...
kelly_flanigan1 Posted March 26, 2006 Share Posted March 26, 2006 Around 1960 ish the asa spec for B&W films was changed. There was abit of a 2x to 1.5x safety factor built in for most faster films. With panatomic X it went from 32 to 25 then to 40 then back to 32 over this weird era. With tri-x it went from 200 to about 400. Alot of folks didnt have electric exposure meters, their exposure meter was the film box or meter computer on the camera. Link to comment Share on other sites More sharing options...

profhlynnjones Posted March 28, 2006 Share Posted March 28, 2006 Hi Daniel, While I'm not certain, I think the Anastar was a 3 element (but very good) while the Anaston was a 4 element tessar type. Lynn Link to comment Share on other sites More sharing options...
