Why not having a look at the Sigma 17-70/2.8-4.5. It might not have a constant aperture through the zoom range, but IQ is good and it should complement perfectly your 75-210.

I have some photos taken with this lens under:
Lake Constance

Mainau Island

Thanks for all your replies

You have all been very helpful. FotoPete's logic won the day. Shooting in a semi manual mode suits my mindset. There are some very interesting older lenses in the 28-70/105 range that will cost me very little. I'll post some photos after I find the right lens.

BTW MO, the database of lenses and opinions is a great asset. The comments on the Pentax-a 35-105 3.5 sure makes it high on my list of possible purchases.

Thanks,
Ken

On a side note, keep in mind that with manual zooms you need to adjust the focal length as you zoom for SR.

That was why between choosing to put in the bag a solid sharp MF Tokina 70-210 and a fairly solid fairly sharp AF Sigma 70-300 I tended to go with the Sigma (not to mention my favourite shooting mode AV is available)

I'll gladly shoot a manual focus prime any day of the week though!

haha Jeremy, you saw that KA Mount Tokina AT-X 80-200/2.8 at Henrys and left it eh?

Wait is this a Tokina 70-210/3.5 you have? (I smell tokina made Vivitar 70-210/3.5 haha)

Ugh all this talk about the Sigma 70-300 is gonna have me buy it one day just for the hell of it.

Set SR for long end

So what's wrong with setting the SR for the long end and leaving that for all lengths?

Hey Pete,
As a matter of fact, I have the KA Tokina SZ-X 70-210/4-5.6 (the one with a red ring). I bought it in Victoria a long time ago (by long time, I mean for a grade 11 photo class )

It is a very sharp lens indeed and I'll be keeping it since it's very well-made and compact (about the size of my Super-Takumar 135/3.5).

I used the DA 50-200 and I prefer it to the Sigma 70-300, which is a relative beast. At $190 you really can't go wrong. The Sigma is quite large fully extended and is about twice as heavy as the Pentax. Mind you I replaced it with a K300/4, which is four times as heavy!

In my experience, mismatched focal lengths seem to cause incorrect compensation. Setting it at the widest setting tends to limit its usefulness at the long end, and setting it to the longest setting causes random overcompensation at the wide end.

Additionally, your EXIF is also incorrect, although this is a trivial matter. However with SR off I'd be perfectly at home.

Wow I though SZ-X was a consumer line. I had a KA Tokina SD 70-2104-5.6 (it has a red ring too) and it was soft and purple fringed like crazy! I recently tried the AT-X Tokina II SD 80-200/2.8. Would have bought that in a heartbeat but it too purple fringed quite often. I'm starting to wonder if perhaps their SD coatings aren't up to par.

I'd use the K300 any day. However the only lens I have in the 300mm range is my RMC Tokina 300/5.6. Its an ok lens. Haven't used the focal length much actually. Been finding the 200mm (300mm APS cropped) more than adequate up until this point.
