I believe it's the post-war version serial# 6243xxx. Any optical difference between the pre-war and post-war versions? Which is better? Thanks! _________________ Nikon D600, Fujifilm X-E1, Sony A7R,

B75 early postwar slim is claimed to be the sharpest wide open and possibly most vivid.
B7,5 prewar is a price rocket and TOP collectible, if OK condition and not messed up with dumb homemade "architects". A bit less sharp, a bit less contrasty, a bit more soft.
B75 postwar fat is most common by far, especially in Exa mount, with less aperture blades. _________________ Angry young man !

Not sure what origin the mess is from your photos. For sure haze probably mixed with various kinds of dust, least probably fungus as these are not too fungus-friendly.
My serviceman would probably do a near-MINT from it again, so seek for sb. similar. I let open at least 5-6 B75 lenses, none of them was really problematic, as its optics is quite resistant and mechanical built just excellent. I believe opening of this lens is such an overrated problem due to general item price range. _________________ Angry young man !

Seeing a good lens infected by fungus is really heartbreaking. If the infection is recent, the lens can be cleaned, but if the fungus is old and has engraved the coating, then the marks are permanent.
The flashlight test can be misleading and convey a worse idea than reality. When it comes to lenses, there is a thing called "beauty defect", which is any visible imperfection that does not affect the performance of the lens. Maybe the fungus affects the IQ, maybe not. The proof of the pudding is to take a photo against a strong light and compare the result with another lens of similar focal length, and see if there is difference in contrast.
Maybe you really want to keep the CZJ Biotar, no matter its imperfections. I dare say that another possibility would be to return the lens and buy another Zeiss, but a new, modern, faster and with more optical and mechanical quality Zeiss lens. I'm talking, of course, of the Zeiss Planar 85mm F1.4 ZF.2. I know the Zeiss ZF.2 is a little more expensive, but it would make you never miss the CZJ Biotar. _________________ If raindrops were perfect lenses, the rainbow did not exist. |

Clearly that lens is defective... you must post it on to me, I will dispose of it properly. Nice find. If it were mine I would likely pay for a pro CLA just to be sure, I have though, opened a few lenses and had good luck with some and messed others up. _________________ photos are moments frozen in time |

Thank you for all the good suggestions. I sent pictures to a shop to hear their opinion. If not keep it , a C/Y Zeiss 85/1.4 sometimes can be found around $600. But the bokeh style won't be the same. Thanks! _________________ Nikon D600, Fujifilm X-E1, Sony A7R,

I'm afraid I have to correct my yesterdays statement when looking at photos properly. Apart from visible scratches the coating layers may be either already damaged or will be damaged when removing that inner mess of unknown origin. (More resistant layers does not neccessarily mean undestroyable.)
Still not sure whether or not aunt Fungus is inhabitating your precious lens or not
Be that as it may, do better photos to determine. These are too reflective and not very well focused.
If you bought it on Ebay as "used" instead of "defective", it might be an interesting conflict but beware you should always return the item in unchanged condition. _________________ Angry young man !

Note: now I see why this happened. You apparently edited the photos in the meanwhile. Hence my yesterays optimistic post based on different, not enlighted photos.
Anyway, the guys are right, the optics probably suffers the combination of all things we clearly dislike: fungus, haze, and fucked up layers as a bonus, altogether probably affecting the lens performance. This lens is like teeth that havent seen dentist for 50 years and should probably be returned. For these money I sold MINT Trioplan 100 lens and for not that much more serviced clean B75 with only very minor cleaning marks...
I bet either focal or aperture ring will be pretty stiff too? _________________ Angry young man !

Inside are dirt, light scratches. haze... (not sure has fungus or not). Looks like someone opened it, I am more worried that because if it was opened but couldn't get rid of the haze (?) which means it will permanently stay. The light bit over exposed the vestige of the haze, but it's there, and the elements are kind vague. Yah, I am thinking of returning it. Thanks to all!

It's not hard to open and clean, I did mine myself.
But since they are worth so much these days it's more prudent to send it to a pro. _________________ I like Pentax DSLR's, Exaktas, M42 bodies of all kinds, strange and cheap Japanese lenses, and am dabbling in medium format/Speed Graphic work. |
