sorry if this a really boring question but I can find the right answer if I do a search.
I've got the old style Tamron 90mm f 2.5 and I am still perfectly happy with the quality.
But sometimes I can simply not get close enough, as this lens only does 1:2.
years ago I had a 200mm Mikro Nikkor, for which I do own the right TC-301 converter. the result is an f/8 400mm macro.
what would you do these days:
get the Tamron 90mm 2.8 (how is the manual focus on this one?)
get a 180mm Tamron
get the old 200mm Micro Nikkor (affordable...)

or hover on fleabay till I find a Micro Nikkor in the modern version

or simply buy a converter to fit the 90mm?

thanks Stray Cat but I have had two bad sigmas... maybe one was just a monday version as it produced horrible colour fringes when used on contrasty stuff and the other one was blurry in the corners. OK they were both fairly recent zooms but I think I'm not going there again.

If your still happy why upgrade and splash out a load of cash, get an extension tube.

How is the 90mm working at the moment when you use it, is that stop down metering.

Yes the ttl will still work but its still stop down metering, most coupled tubes should be ok.

If you are using the old adaptall 2 tamron 90mm there is a dedicated extension tube for that which fits between the removable mount an the lens. There is also a very high quality 2x converter, the 01F, which works in a similar way, which would give you a 180mm. Under test in a camera magazine years ago the 01F beat all comers but i'm not sure how well it will hold up on a DSLR for colour fringing.

I had a x2 converter and figured removing the lens elements, turning the converter into an extension tube would convert a 1:2 to a 1:1, I don`t think I was far out.

There`s more info here and a calculator.

Yes and they were often sold together as a kit.
