Tamron Twin-Tele / Taisei Kogaku Tamron Twin-Tele 135mm f/2.8

I mentioned this lens briefly in my blog thread (Link: Notes from the Top Left Corner )

I have had the lens for well over a year now and have liked it but not really spent much time getting to know it properly. I've spotted flashes of greatness with, but never really 'learnt' it.

The earlier f/4.5 version seems a little more common than my 2.8 one. By all accounts, this was the first lens that really worked as well as buyers and reviewers hoped it might with a matching tele-convertor. It was also the design that gave Tamron its name. It was marketed under several model names aside from the Twin-Tele one - Converto-Tamron, Duo-Tamron.

Mine is a little tired cosmetically, but I think it is capable of producing some really great pictures.

It's a pre-set T-Mount and I adapt it to my Canon DSLR and a Sony, as well as using it with the Spotmatic M42 and a few Pentax K-mount bodies. The included tele-converter transforms it into a 225mm f/5.5.

The aperture configuration will have some bokeh freaks wetting themselves, with its 12 blades.

I decided to spend a few days solely using the thing and had some fun in doing so. We spent Christmas over in North Lincolnshire, with spitting distance of the Humber bridge. A pre dinner walk took us to the local wildlife trust reserve and it got me obsessing about the sedges growing there.

I already posted a similar one to this, with the bridge, on my blog thread, but this one, I like even more.

Moving on closer to the pond, I got these two (above and below).

We followed a creek that spills into the estuary within sight of the southern support tower.

Love that last one. My favourite though is the first of the two close-up shots of the sedges. The sense of movement makes it I think. Those reflections are very nice too.

This is proving to be an interesting and very capable lens.

Now, where are those pictures of Bexhill then?! ;)
