It’s been a long time since I did my “First Thoughts” post about this lens, and the reason I’ve been putting off doing another review post on it is that my particular copy of this lens has some issues, stemming from what appears to be a service by someone who didn’t know what they were doing. Anyway, I had put it aside to send away for a service, whilst simultaneously keeping an eye on eBay and other sites for another affordable copy to purchase in the meantime. As you can probably tell, I haven’t had any luck, so today I bit the bullet and disassembled it myself to see what needs to be corrected.
Which pretty much confirms to me that this lens wasn’t serviced correctly, but there’s not much I can do about that now. I have it in pieces, and I’m performing a full service on it – cleaning the glass, lubricating the helicoids, cleaning and drying the aperture mechanism, regluing the felt that keeps the built in lens hood smooth, and doing a quick touch up on the cosmetic condition whilst I’m at it. Hopefully once I’m done with all that I’ll be able to do some more testing with it.
In the meantime however, whilst I had it in pieces I noticed that the middle element group is quite an interesting little piece of glass. I don’t know whether it’s the lack of sleep or large quantity of caffeine pulsing through me at the moment, but I decided it was interesting enough to shoot.
So, here I present the center element group of a Carl Zeiss Jena DDR 135mm 1:3.5 MC S lens, shot with some creative lighting on my 60D with a Canon EF 100m 1:2.8 Macro USM:
Once I’ve got it back together and working properly it’ll go back to being one of my most used lenses I think.
