If it doesn't say SMC it's the non-SMC version which will also have
a RED button to release the A setting on the aperture ring instead
of a BLACK one. The internal design of the two lenses is different.
They do look multi-coated, but it doesn't say SMC on the lens.
Both have metal mounts.

Still quite a decent lens and Made in Japan. One did sell on here
for about £30 a few weeks ago.

There are two versions of the Pentax-F zoom 1:35 - 4.5 28-80mm SMC
and non-SMC plus a Takumar version.

It needs to be clarified which one this is?

And the hands on the clock go round and round
I just wake up and it's time to lay down,
Life gets teejus, don't it.

Edit: Wink Martindale (best) version on youtube link

My 300mm A* is in similar condition, but these are made as
tough as electric drills and it doesn't effect the
performance which is superb. Works well with a TC

The latest shot in my portfolio of the Grebe was
taken with my 300mm A* on a K20D handheld.

A proper slide rule is about 3ft long
Otis King was one of the best link

I've got a fairly mint one.... should have sold it when they
were going for about £150

I like Rumbledthumps linkusually with a steak

Sainsburys do a decent chilled version.

There's a charge of about 3.6% on gifts sent to friends/relatives
via a card. 0% using a Bank Account.

You can now buy Pay as You Go Cards which would make money
laundering possible, so I suppose they have to control it.

Keep an eye out for the Pentax Telephoto Diffuser AFT1 which slides into
the slots link and put a piece of diffusion material over it and it's perfect.

It depends on if I can focus it on the K-5 without needing
more than -10 correction which is the maximum

At 30mm it should be OK at f/8 and ININITY focus

The lighting obviously is beyond your control, but you've managed quite a good professional looking set under the conditions. It's nice to see a bit of motion in some of the shots.

The first two are really too dark for me. It's a pity there wasn't a backlight on the first one.

The fourth one shows how poor the lighting was. It's actually burning out the guitar players hand making it too noticeable.

The only other shot I don't care for is the 9th again the flat lighting is the problem.

The rest of the shots IMHO are 1st Class and I'm sure that the band could make good use of them.

I'm having problems focusing my K-5 as well some lenses need beyond -10 and visual focus seems very hit and miss.
