Indeed it is as they are very far and few between these days.

So all in all a bit pointless then :

I didn't look into it that much but presumed it had an aperture ring as it is missing the contacts to do it in body.

Took him out this morning Peter, he's 11 years old and getting on a bit now.

We have bought him a ramp to get in and out of the car boot but as they say, you can't teach an old dog new tricks and I have to agree with that

Nice second post Would like to see some pictures from it

I have the Sigma 180mm f/3.5 macro and was not sure whether to sell it and buy the Irix but the lack of AF (not that I really use it for macro) and the fact you can't alter the aperture via the body ( correct me if I'm wrong but it has to be done on the lens?) has put me off slightly.

Where are you in Dorset btw ?

Damn, knew I shouldn't have told you to contact Sigma about the 17-70mm David

What I keep looking at though is the IQ of the actual lens pictures ... you would never know they were taken with a phone and not some decent quality standalone camera.

As I continue to replace my Sigma lenses for the Pentax equivalents the next lens up for sale is the Sigma 24-70mm f/2.8 DG EX HSM. This is the last (and best) version made by Sigma for Pentax and is in virtually mint condition. It has had the K-1/II/KP mount conversion done by Sigma and comes boxed with caps, hood and case.

After £450 including UK postage.

Lens sold.

Thanks for looking.

Thanks for the comments guys ... 100-300mm f/4 still available and reduced to £725 incl postage (UK)

A few shots taken with the lens at various focal lengths wide open.

TBH I don't think the Pentax version could do any better.
