Tamron Adaptall-2 SP 72B (90mm f2.8 macro)

I was surprised to find this lens missing from the archive list...

this is the last of the Adaptall 90mm macros - after this lens, Tamron moved to individual mounts and also auto-focus...

it moved from the 52B/BB's 1:2 native macro to a full 1:1, without adapter/extension, but kept the former model's wondrous ability to 'snap' in focus....

I suppose it wouldn't be fair to expect you to run this thread single-handedly...

Evening Bleeding Hearts. K-3 II, 72B. f/4, 1/60, ISO 100.

What's this like to swing around vs. the 52B? I like my 52B's relatively small size, relatively fast max aperture, and focusing "feel". It's a heavy little thing, though, and I know on digital sensors it can leave a light spot in the middle of the frame in bright light with the right set of circumstances due to a flat rear element (or so I've read).

Would you rather go out walking with the 72B or the 52B?

the 72B is a physically-larger lens, but weighs about the same, maybe less - because it's not metal; it's a composite-bodied lens...

I've also read about the rear element reflection issue.... but have never seen it with the 52B or the 72B...

I love the 52B, but the 72B is a desert-isle lens for me ... everything I love about the 52B (colors, clarity, bokeh) is even more with the 72B....

the 72B takes photos that I don't believe are mine - it's better than I am...

I have owned the 72B for several years, and owned a 52BB (without the 1:1 extension tube) for a short while before I sold it. So, I had a chance to compare both lenses at the same time. I believe that the 52BB is slightly lighter than the 52B but identical optically.

I thought the 52BB was a wonderful lens. It's a classic telephoto macro lens, offering outstanding sharpness, high contrast, and wonderful bokeh thanks to its 9-bladed diaphragm. It’s capable of very detailed images at a magnification ratio of 1:2, and the 320-degree focus throw delivers easy and precise focus. It's a solid, well-made lens.

Had I not owned the 72B, I would have been very happy to keep the 52BB and carry it in the field. However, without the extension tube, the lens is limited to a 1:2 magnification compared to the 1:1 of the 72B. In the end, I decided to keep the 72B because I don't need two 90mm macros, although I was sort of sad to see it go!

I had not used the 52BB extensively, but never saw any sign of the purplish reflection that is occasionally reported with the 52B. Similarly, I haven't seen any issue from the 72B.

Me too! I could swear I added it, but perhaps it was just good intent gone awry. To remedy, here are a few examples from my work.

Sankyō Kōki, Komura 135mm f/2.8-f/22 (gear P*rn)




Two Too Many Exaktas
The title reflects the fact that I have both a VXIIa and VX1000.




Dedicated Rarity...or not
The title refers to the dedicated hood for the Tamron 28mm, which turns out to be readily available through the usual online stores...go figure.




All of the above taken with the Pentax K-3. Click through to Flickr for details.

Yet, more gear p*rn; it turns out that the 72B is well-suited to product photography and gear-as-art work.

Steve

with its super-smooth focus helical and ability 'pop' into focus, it is perfect for such things...

awesome shots, Steve!
