Tamron SP 90

I'm 99.9% certain it will but can some one confirm that this lens will allow shutter priority with a PKA mount?

Just don't want to buy the wrong lens!!

Can't be sure about that. Do you have a Pentax fit Adaptall 2 mount as there isn't one with the lens.

You might be better looking for a manual focus Pentax macro lens which will be much more compact and will be sure to work 100% correctly.

Thanks for the reply

I have the PKA mount for the Tamron 19AH, I'm assuming therefore as that one allows shutter priority this one will. But I have been told that I shouldn't always assume things!

What makes me hesitate is that there are several types of Tamron 90mm - I wouldn't want to assume the one on offer will work OK with the Adaptall 2 mount.

Someone here might actually have one, so we may get a definitive reply.

I think Mike-P has this one and uses it with a PKA adaptall 2 mount.

I would say yes it would allow shutter priority and be surprised if it didn't. Mike will know, he has the all seeing eye

I have the 72B 90mm adaptall 2 mount macro lens and it works fine.
I am also 99.9% sure that one will work with it .. but not having one Im loathed to say 100%

Mike...I am looking at the 72B for use with my K10. Would you reccommend this lens. I only intend to use manual focus. Presumably I would need an adaptal mount to Pentax. regards Ronald.

Its an excellent lens, you will need a PK/A mount if you want to use the A setting on camera or just the PK mount if you dont mind doing it via the lens itself.

thanks Mike I have sourced a 72B but the adaptall is more difficult. There seems to be severaal mounts out there and I am concerned to get the right one and the adverts are not always detailed. I am told that the PK/A is difficult to find and costs about £50 or so which would pull my costs up £230 which leaves me wondering if a new Pentax fit lens would not be the better bet. Have you any views on this or know where I can best source the PK/A mount. Happy New year..and thanks again for your advice. Regards Ron.

£230 is too much for the lens and mount, infact I wouldnt be paying anywhere near that amout to be honest as you are in the realms of the newer AF lenses for that.

Mine cost me £75 with the mount 6 months ago, admittedly a very good price but personally I wouldnt be looking to pay more than about £140 for the combination with the PK/A mount being able to fetch £50+ on its own.

Time to start looking at Ebay or a new Tamron AF/Sigma 105mm I would say.

I have an adaptall 2 PK/A mount in stock - used of course, but in good order.

I was going to shove it on Ebay, but would take £35 including delvery.

Let me know if you want it - you can have first refusal!!

Hi Chris,

Does your adaptall adapter come boxed?

Provided it is 100% functional (I've come accross one once that didn't transmit the aperture correctly - by a third or a half stop - due to some mechanical issue), I would be a taker, if Ronald doesn't want it, obviously. (delivery in London)

All 3 of my PK/A mounts overexpose on all of my Adaptall 2 lenses, I think its a "Feature".

Careful Chris, you'll get your hand bitten off!!

What realistically, should I be expecting to pay for a mint condition Adaptall 2, 90mm, f/2.5, 52b/52bb (without mount)?
