Lense Serial #'s consistent with Camera SN?

[john_philllips]

I have a 3.5F with a Planar taking lens in the serial number range

of 4xxxx, and a Heidosmat viewing lense in the 3xxx range. the

camera number is 225xxxx. I've been told the 6-element planars were

above 4xxxxx, but that these didn't start appearing on cameras until

around 228xxxx. Trying to determine whether the lense SN's are

consistent with each other and with the camera SN. Any thoughts

appreciated.

Your camera with number 2,25x,xxx is an early third model 3.5 F and should have the 6-

element Planar. According to Mr. Prochnow's book the 6-element Planar started with the third

model at lens number 2,753,002. His book also shows a photograph of a second model 3.5F

with a Planar in the 2,989,xxx range. As far as I know there is no definitive list of lens

numbers linked to camera numbers. I would like to add that the 6-element lenses were no

better than the 5-element ones. They were cheaper to produce in the required quality. This

5/6 element matter is a bit of a hype.
