also, any good repair shops to try in phoenix? thanks. curleyQ

Your husband had a 1.4 lens! I also have a lens collection of f1.4 ,
really quality glass, produce special images. If I dropped the lens I
would also seek it's repair.Can't recommend any repair shops to you.
If my wife dropped one of those, she would have to search for a new
husband.

If it's a 50mm lens, you're just as well off getting him a new, used one.
If it's screwmount (threads on the end that mounts into the camera allowing
it to screw in just like a mayonaise jar screwing into its cap), check here:

series of flanges around the edge that fit into matching slots on the
camera, and then twisting and locking into place), check here:

In either case you can get him one in excellent condition (which will look
like new if you buy from KEH) for a little over $100--a repair would likely
cost you that much anyway, though I suppose it wouldn't hurt to ask, in
which case, KEH has an online repair estimate, though for broken (dropped)
equipment, the rule is they can't really say how much it will cost until
they've opened it up and had a look.

DO NOT FORCE IT.  IT MAY NOT BE BROKEN AT ALL.

The "Auto/Manual" switch moves ONLY if the lens is mounted on the camera.
It was designed to afford backward compatibility for older model Pentax
cameras that existed prior to the introduction of the Spotmatic.

If you look carefully at the lens mount, you will see a tiny pin--so small
that you might miss it if you are not careful.  That pin is compressed when
the lens is screwed into a pre-Spotmatic camera, allowing you to move it to
the "Manual" position.  If you have a Spotmatic or ES camera body, the
switch should be left in the auto position and not moved.  You do NOT
require the "Manual" setting on Spotmatic or ES model cameras.

If you have the rear lens cap, screw it on, and it will compress the pin.
Then you can gently try to move the Auto/Manual lever.  If you can get it
into the Auto position, just leave it there.

REMEMBER, THE LEVER REMAINS LOCKED WHEN THE LENS IS NOT MOUNTED TO A CAMERA,
OR WHEN THE REAR LENS CAP IS NOT SCREWED ON.

Let us know if this works.  And tell us what camera model you are using.
Whatever you do, never force this lever.  Many uninformed people have broken
it, trying to get it to move, when all they had to do was to first screw on
the rear lens cap to compress that tiny locking pin.

Almost anything can be repaired.....The question is, will the cost of
repairing it make it worth while, or would you be better off buying a new
lens?

Since it has that auto/manual slide it's thus a screw mount lens.
Depending on the version
( Super Takumar, SMC Takumar, Super-Multi-Coated Takumar )
it can be replaced for between $30 and $60 on eBay or whereever you
can find one for sale.  They're excellent lenses but because of age
they're not in high demand.  So the price is right.  And service work
can't be had this cheaply.
(The Super-Multi-Coated Takumar is the lens of choice here.)
