Dilemma -

I have a Tamron 90mm (plus Extension tubes and Converter etc) that I've been relatively happy with. Results are good but...

I've had my eye on the Sigma 150mm. The extra reach from the lense would be very welcome , also it has internal focusing meaning that the end of the lens doesnt suddenly start shaking the plant on which my subject is sitting as I focus in on it. I've heard good things (and seen great pictures) from this lens.

I think the only thing I miss from the Tamron is that I do need to get very close for dragonfly and butterfly shots.

As the poker gods smiled on me last night I have the cash to almost cover the cost. Especially if I then sell the Tamron.

Has anyone got both the lenses or switched similar to this?

Anyone with the Sigma comment on how this lens is on handheld shots - the Tamron is pretty easy to handhold, just wondering if the extra length will mean more time on the tripod ...

Any advice or opinions welcomed.

Thanks
