Fuji XF 27mm 2.8 - disassembled

[yukosteel]

Once I repaired Canon EF 85mm f1.2 lens that looked like that. Fortunately it was just broken filter. Once I removed all glass parts, cut the filter frame and took it out - it happened that front lens  element was not damaged at all.

Now we know the 85 F1.2 not only have a huge front glass, it's tough too!

 

I only managed to remove the rear glass of the 85 F1.2 to clean the rear elements. Even then I was a nervous wreck! Mk1 version and discontinued. Means no parts from Canon.

hi! very well done! i have this lens and last week i tried to clean it but actually i had a problem: i was in a cleanroom and a drop of ethanol fall on (i really didn't want to wash the lens with ethanol, but the optical paper didn't absorb the solvent at all) and inflitrated behind the front lens, obviously leaving a stain. anybody has an idea on how to remove this stain?

 

thank you in advance!

I followed your instructions, however, the dust I wanted to remove (visible at f11) was between the front elements. Has anyone been lucky with this? My best guess is that you could use a suction tool to see if unscrewing the middle element is possible.

You rock evajaj ! : ) So looks like four screws are located under the inner front plastic ring, great job disassembling this piece!

Does that front plastic ring unscrews through the filter thread?

Thank you yukosteel   .No.The Front plastic plate and plastic barrel are joined together by glue. to disassemble the front plate without damage it, i decide to push it from inside of barrel.

to do this i make hole on the barrel from inside of it and push the front plate through this hole. you can see this hole on the picture near the 4 screw hole.
