A lot of these old lenses are soft in the corners on APS-C. I can't imagine they will be any use on FF (which is more than twice the area) apart from as a Body Cap if you lose the FF Body Cap

The 43mm Ltd should be OK.

24mm and 28mm Pentax need to urgently re-design these even for APS-C.

I've seen good results from the 50mm 'A' f/1.4 on FF via an adapter.
The FA 50mm f/2.8 Macro should also perform well.

They are doing the Pentax AF-540 FGZ Flashgun for ONLY £99.97

Is that cheap or is that cheap!

Hmmm! I've got 2 of these and I just tried one on a K-5. It was already set to 'A' and the aperture only worked from f/4 to f/32. I pressed the green button to take a meter reading at f/4 and then set the lens off 'A' and at f/4 manually. Slight difference in readings could even be a stop.

Without touching anything else I set the lens to 'A' again. This time it went down to f/2.8 so maybe you have to set 'A' on the camera with it switched on.

Is the set to Manual metering? It should be.

Are you using LV, because LV closes the aperture down automatically if the scene is too bright.

Sounds like the contacts..... Try cleaning them. Waggle the lens about a bit when fitting it.

Top lens.

Very nice shots.

The removal of the PF has added a lot of unattractive green/cyan to the girl. She now has a necklace and green marks on her red lipstick plus green lines under the eyes.

If this was a commercial shoot it is a good example of where you should play safe and not try to be too arty farty, better to play safe and stop the lens down so that PF doesn't happen

Is that a Pentax on the Cover? The lens looks like Pentax as well and the lettering is a similar typeface.

Ringo confirmed that they all bought Pentaxes in the notes for Photo 12. Self Portrait using a Nik....cough!

Ringo Starr: 'Photography has always been of interest to me. At one time, we all had cameras. I think we all bought a Pentax in Japan the first time we went there.'

Ringo is also trying to get together about 25 photos each taken by the other Beatles for another charity book.

Good to hear Canikon are catching up

As long as Pentax don't bring out a lens with an AC Motor I couldn't care less...... although I'm never far from a 13 amp socket even when I'm down at the pub

Do other makes have a quick-shift system?

I was going to say I've got one, but Lennyblokes scoopered all chances of anyone selling theirs. I paid £120- £130 each for the two I have.

Possibly Pentax's best TC although it's not AF which is a pity.

I keep meaning to test it against the latest 1.4x, but haven't done so yet.
I'm not sure it matters, because one's AF and the other isn't.
