A miracle lens, a miracle shot.

Hello all,

Recently I disassambled a collapsible FED 50mm f/3.5, cleaned it and reassembled it. I tested it and the result is so unbelievable, so want share it with friends here :

:eek:

CAN I send you all my lenses so you have them cleaned and reassembled !? :D

Now seriously, that thing is SHARP ! So maybe it's really worth to take the thing seriously and start learning how to clean and assemble a lens.

They're sharp allright. A hundred questions pop to mind straight away...

What kind of seals did you find in there, what condition were they in?
Lubricant, what did you use on re-assembly?
How did you clean the glass?
Did everything go back together properly - any parts left over?
Did you burr any little screws, or have any anxious moments?

Your lens does look sharp, congrats on the nice overhaul.

I've found most of the Soviet lenses can benefit from at least the focusing threads being relubed, it makes a world of difference for a user lens. I doubt I'd "teach myself" to service a Leica lens but with the Soviet copies I was happy to get stuck in. The collapsible lenses are very good quality from what I've seen, the later Ind-50 is said to be the best of the bunch but I've had excellent results from the Ind-22 and FED (Ind-10) lenses as well.

Not only that, but we want the 'before' and 'after' pictures as well ! :D

Guys,

I didn't expect all these responses, in fact I did it because of John Robertson, he has proved the FED 50mm is a gem, that's why I gave it a shot.

The cleaning process is an interesting story, I will find a good way to show to all you guys ASAP, but don't expect too much, my methods are quite DIY, and don't try them on the CV or Xpan lenses.

I will keep all you guys informed ASAP, OK ?

You know, I have an Industar 61 LD with a toupee between the elements. Maybe there is hope for it yet.

I've tried disassembling my lens and I realised there's such a tool as a "lens spanner" acc. to the websites to unscrew the plastic bits holding the lens in place. Anyone know what can be used in place of a proper lens spanner to open it?
