Advice on performing a CLA

nickthetasmaniac · 11-01-2015, 05:47 PM

Hi everyone,

I was wondering if anyone had advice on performing a CLA on a Spotmatic SP F with SMC Tak 50/f1.4? I have one which has been sitting unused for probably 25 years now (I ran a roll through it maybe 10 years ago), and desperately needs some love. I like tinkering with things so I'd like to have a go at it myself - it's basically a paper weight at the moment, so no great drama if I stuff it up!

Fair to say I have no experience pulling cameras apart

Any guidance would be great!

Cheers, Nick

My advice is to send it to dcshooter

The cameras are easy enough to service if you have the tools, but calibrating the meter and shutter requires instrumentation.

Camera service manuals
Their Spotmatic service manual is excellent.

OP's in Australia; postage is going to be a bit on the high side.

I would send the camera to Eric in the USA (postage is high, but the service is great and comparable to AU costs).

The lens can be done at home and would be a good project. You will need three tools. A wrench to take the vanity ring off, a spanner to remove element retainer rings and a standard screw driver (small) to take the screws out. Very low risk and good fun.

Well low risk is dependent on being practical.

But a K 1.4 needs

Plastic ointment tub to just clear the 49mm threads cut a ring from rubber gloves to clear the glass and filter threads sandwich and unscrew name plate.
The rest just needed rubber gloves for grip needle nose pliers pretending to be a lens spanner grinded down to just fit slots on file or diamond dust pad.

Mine had fungus several elements down but the lens retaining rings were not tight.
The fungus cleaned off like dust no detectable damage, ladies hand cream, the real problem was getting the residual oil from the cream removed.

Think I needed a screw driver as well.

The big thing is stopping before getting stuck, a coffee break is key.

My lens had nice build quality.
