Soligor / Tamron 450mm F8 T-Mount

All, I picked up one of these: Tamron 880 ( soligor ) preset t-mount 450mm f8 Lens Reviews - Tamron Lenses - Pentax Lens Review Database for $20, as the aperture is stuck at F11. It seems to me that some people had taken this lens apart rather easily for cleaning and repairs. I have a lens spanner wrench and appropriate attachments. Does anyone have any experience with this lens they'd be willing to share? Thank you!

As you can see from the pic the lens separates right by the preset aperture. You probably don't need to disassemble further, (update the aperture rings are liable to slip off by themselves so might as well do that, watch out for the ball bearing) it is usually sufficient to dip the end in solvent - I use coleman fuel - until the gummed up blades loosen and can be delicately brushed/wiped and opened/closed to make sure the movement is free.

If there is is a streak of gunge from the helicoid due to deteriorated lubricant (which is how the blades got gummed up in the first place) then a full repair would be to clean and relube the helocoid as well.

addendum I am aware I need to re-upload many of my pics in the reviews...

You're welcome.
Decent lens btw - at least the first example I had was, the second (in the pic) wasn't as sharp. But I prefer the 400 f6.9's.

Yes. I rate the 400 f6.9's the best of the 1960's type "wundertute" telephotos. But the later tokina made soligor/vivitar 400mm f6.3's are very close.

Okay - help me out here - "wundertute" is "Wonderbag?"

How do you think the 400mm of the two types you describe compare to the 30-600 Adaptall SP with the TC?

Also, do you think these are the same?

Not the tele-astranars thats just a reseller generic t-mount, unknown manufacturer. The rest are all tokinas, most are T4/TX (= same) mount (bushnell looks like fixed mount, not seen a bushnell one before actually, optomax's are not uncommon). Note the tx's can be id'ed by the double set of coloured f numbers on the aperture ring and the protruding release catch mount on the side. Side on they look a bit like a cfd mount. The removable mounts all have id letters on; PK, OM etc Most common T4/TX mount is M42, look around for a PK. FYI note links

$35 is a very decent price imo... (but no mount). KEH one <20 bargain!

Yeah - Tele-Astranar seems to be generic, re here: Preset, t-mount (Tele-Astranar, Impakt, Photax...) 400mm F6.3 Lens Reviews - Miscellaneous Lenses - Pentax Lens Review Database

Do you think the Bushnell IS one of the Tokinas?

The KEH one seems like a decent deal.

I'm still trying to decide if my Sigma TC with one of these will be better than my 60-300 SP with 2x TC.[COLOR="Silver"]

Or, I can save up for one of these bigmas: Sigma 170-500mm F5-6.3 APO DG Lens Reviews - Sigma Lenses - Pentax Lens Review Database :P

I wouldn't use any of these old designs with tc's! The point of comparison is 300mm + 1.4x tc against straight 400mm.. adaptall 23A is a good lens but I would expect one of the good 400's to edge it. i have gone off 2x tc's pretty much completely except occasionally with my 300mm f2.8 - a different calibre of lens to what we are discussing.

If you can get that bigma for 300 bucks, or even $170! (good luck, fact is there are plenty of pentax users looking for these, I would normally expect prices to be nearer or above 500 ), then that's your answer. A relatively modern lens, AF. But you can't knock decent pics for $20...

Thank you, Marcus! Much appreciate the advice, as always....

Also, I have found that the 60-300 with the T/C is exceptionally clear for what it is.

014F does well. And one big advantage of the 23A + tc is the much closer focussing.
