const f/2.8 manual focus zoom?

Are there any? I want a const 2.8, but looking for a cheaper alternative than the autofocus ones.

ON ebay I currently saw one older Tamron SP 80-200/2.8, which would be quite cheap:

Tamron SP 2,8/80-200 LD mit Adaptall Anschluß + Blende bei eBay.de: (endet 12.10.08 22:44:01 MESZ)

and

Tamron SP 2,8/80-200 LD mit Adaptall Anschluß bei eBay.de: (endet 30.09.08 20:29:55 MESZ)

The seller is reliable, I have bought some lenses from them.

What focal length do you want???

In Manual focus, I can think of the Pentax A 80-200, and perhaps a similar tamron.

at F3.5 there is a vifitar series 1 70-210.

I am not so sure about any shorter zooms in MF

tokina

There is one Pk tokina 80-200 f2.8 manual.

There is another version PKA tokina 80-200 f2.8 manual zoom. PKA comes with aperture A setting and lens is quite heavy. I paid about US 300/ six months back for this lens.

Pk mount, I believe there is one in the market place. Try searching for the seller JM.... from australia/ or tm... by that name.. Still available few months back. This lens works on stop down approach.

I used to have the old Tokina 80-200/2.8 PK (without A) and it was a good lens, but I doubt it has enough resolution to be useful beyond the 10 MP barrier. The A-version seems to be rare, I haven't seen one in a long time on ebay. The advantage of the Tamrons is, that you can add an PKA-adapter, which makes handling much more convenient, than an old PK-lens.

Tamron makes an SP 35-105 f/2.8 also in adaptall mount. Its rated high in photodo 3.6 MTF for a zoom. I had one for a minute and it is quite sharp.

I know you were asking for a zoom lens, but I bought a Sears 135mm f/2.8 prime for $40 on this site, and have been very happy with it!

Has anyone heard of the vivitar series 1 35-85mm 2.8? I just saw it at a used camera store and want to know more about it. It's the m42 version

I have an old Rikenon 35-70mm with a constant minimum of 3.5 that takes wonderful pictures, but it seems pretty rare - most Rikenons have variable.

I just got a Sigma 28-70mm "A" style manual zoom. I haven't been able to find much info on it but my first shots seem good so far.

There is also a rare Tokina 35-70/2.8, which served as a standard zoom in film days. I used to have one of those and it was a fairly good lens.
