Thanks a lot for this upload. And GUSH... How many frontal element glasses this lens has!!! I was considering buying one at a dirt price, with lots of fungus under the front element but seems its a lot more hassle to clean, than what I thought. Again thanks man for your very good, informative video clip. Hope to see a lot more from you. Subscribed and Thumbs up.
I've disassembled all the optical elements very easily and put everything back together again the right way but now I've lost infinity focus. I've tried disassembling/assembling several times again but it only focuses up to 20 m or so, I'm clueless!...
Infinity focus is affected by the distance from focus group lenses to the sensor; so check the rear group for washers or spacers missing or misplaced. Also, check the gearing for focus and focus stops detents.

Full frame uyumlumudur?
My canon lens hood got a dent and trying to remove them. Don’t know how.
is that canon lens?
No sir 400mm for nikon
I think these lenses were often sold with different mounts, presumably the actual lenses etc inside are the same.
