Need help identifying guess value C mount lenses.

[JerryMK]

Hi everyone, I just bought a Bolex 16H camera with 5 C mount lenses included. I am new into this C mount lenses so need some help from you guys. Wonder if I bought nice lenses, value$? And how about the usage with the G1?

These are my new lenses:

From left to right:
#1: Computar TV Zoom Lens 1:1.2 / 12.5mm-75mm
#2: Wollensak 1/2 Inch f/1.5 Wide Angle Cine Raptar
#3: Carl Zeis Jena Blotar 1:1,4 f=2,5cm
#4: Wollensak 1 Inch f/1.9 Cine Raptar
#5: Wollensak 1 Inch f/1.5 Cine Velostigmat

Interesting post!

#1: Computar TV Zoom Lens 1:1.2 / 12.5mm-75mm

No way this one is going to fit the G1 without major adaptation... $50 on a good day

#2: Wollensak 1/2 Inch f/1.5 Wide Angle Cine Raptar

Somewhat rare, I'm guessing 14-15mm IC. if it's smooth and clean... could fetch max $100

#3: Carl Zeis Jena Blotar 1:1,4 f=2,5cm

Zeiss fans may dig this tele, looks lovely, not sure if it will fit the G1, never seen one like that in c-mount... hard to say... $150?

#4: Wollensak 1 Inch f/1.9 Cine Raptar

somewhat common, full coverage and mounts no problem - bout $75

#5: Wollensak 1 Inch f/1.5 Cine Velostigmat

Looks lovely, never seen a f1.5? maybe full coverage and probably mounts no problem - bout $75 maybe more?

Thank you ver much for your reply. Just tried to fit the lenses on my JinFinance C Mount adapter and all work but the Carl Zeis

So even the Computar TV Zoom Lens 1:1.2 / 12.5mm-75mm fits like a charm. Actually just that on is missing in the picture but you can see it on the first picture with the adapter already on it!. I'll post it one the G1 later on.

Zoom Lens is always a gambling of c mount selection. Just so curious to know how is the coverage of the Computar zoom. I used have a made in China 16mm Cine lens with 9-90mm that can just fully cover the sensor from 40 - 90mm. Hope your lens can do it better than mine.

Carl Zeiss Jena Biotar 2,5cm f/1.4 is prewar

Just found out the CZJ lens is a prewar lens. Till now seems to be very rare, can't find much more information on this lens...?

 

[JerryMK]

For those who are interested, seem the Carl Zeiss Jena Biotar 2,5cm f/1.4 is a rare felow. Just found this:

"Robot II für die Wehrmacht, mit einer seltenen Ausführung des Carl-Zeiss-Jena Biotar 1:1,4 f=2,5 cm"

So, a little less than USD100 back in 1934... Those were days when one really had to save for a long time before buying camera gear! It's an interesting bunch of lenses you got there.

BTW; there doesn't seem to be a lot of people appreciating alternative lenses over at DPR...

Thanks Jonas. LOL, you are right about DPR, I find it a techie forum where it is most of the time about the sharpness of the picture. And I think there is more.
