Was this Tamron Sp 60-300 a bad buy?

So I was taking pictures at the part today and noticed two things, I want more magnification and i want to be able to do macro shots. After a lot of reaserch i figured this lense can help me with both of those.

I found this ebay auction but its a little wiered.

Tamron SP 80-300mm f/3.8-5.4 Telephoto Zoom/Macro Lens for Adaptall 2 Mounts | eBay

In the listing it says the lens is an 80-300 but if you look at the picture you can clearly see that it is a 60-300 if you look at the markings on the side... This is how the glass was described "Very minor spotting from haze, no fungus or scratches" I figured that may be what was keeping people away from it but i couldnt resist. Im cheap like that. But now im worried that maybe this will affect the image quality more than i assumed originally. Its too late now, but what do you all think?

And what does it mean when the zoom is "slightly under-dampened"?

Thanks for any help.

It should be a "23A" ... 60-300mm

QuoteOriginally posted by dmbaile2 Quote
Bonjour,

I have a "23A" and it has a good "macro" function ( "1:1.55" - written on the lens itself ), but unusable with an onboard flash because one's lens is too close to the subject. One can also use the "01F" TC with it, too.

Also see : Tamron SP Adaptall-2 60-300mm F/3.8-5.4 Model 23A

Plus : http://www.adaptall-2.org/lenses/01F.html

"Slightly under-dampened" could be a "zoom creep" issue ... which mine has a bit ... not excessive at all for a large, heavy lens like this one.

Hope that this is of some help and send us some sample photos ... bon courage!

Salut, John le Frog

From the posted images the lens looks to be in reasonable shape, so I don't think you did badly here. This adaptall lens is one of the few standouts from their product line, particularly from the zoom collection.

I'm guessing that underdamped zooming means that the lens suffers from zoom creep - i.e. it will slide forward on its own due to its own weight and/or that it slides pretty easily. On some zoom lenses there are screws that can be tightened to fix this, or it can be partially fixed using the equivalent of a giant rubber band. Just search for zoom creep on the forums.

If the haze doesn't affect image quality, you did very well. I have one & it is extraordinarily sharp. That one & the Pentax-A 35-105 are the two sharpest zooms I've used. The only downside on the Tamron is some susceptibility to purple fringing, but every other aspect of it's performance is superb. I'm never getting rid of mine.

The macro mode on it is quite useful, too. Not quite the equal of a regular 1:1 macro lens, but you can get pretty darn close with it, nonetheless.

Will this lens accept a normal k mount teleconverter if I use the proper adapter?

Re-bonjour,

Never tried that before since I have the 01F TC, so got out some gear and experimented.

Used the K-r which already had an old "Teleplus MC4 2x KAX" TC on it ... Results = _____________

The 23A with a PK/M mount ... all worked in manual.

And the 23A with a PK/A mount worked with "A" function for "f" stops, too, since the TC has "A" pin connections ... et voilą!

Learn (and/or try) something new everyday ...

Salut, John le Frog

The SP 60-300 (23A) is generally considered a very satisfactory lens within its competitive price group of 70-300 zooms. If you check the Adaptall Club you'll find quite a few favorable comments there.

If you experience any noticeable degradation, it will probably be a relative reduction in contrast and that's often correctable in post processing.

It's a versatile lens -- enjoy it.

The only question is whether it is really worth the risk that it is not in as good shape as you might hope and the hassle of completely manual operation plus the need for an adapter just to save a few bucks over the cheap and very good modern options, like the DA50-200, Tamron 70-300, or slightly more expensive DA55-300. OK, the macro capability on the 60-300 is a bit better, but stick a $50 Raynox closeup lens on the front of any of those zooms and you;ll get far better results still.

Look at keh.com, they usually have one or two of these. Just to compare prices. They aren't expensive.

It is a very nice lens. A good copy is easy to handle and sharp.
