Well yes, you're used to Sigma throwing all kinds of two and three-letter abbreviations at you so you know that this new lens - that should now be in shops according to Sigma - should be a real winner for all owners of Sigma-, Canon-, Nikon-, and Sony-DSLRs:
- APO: apochromatic design, should have only little longitudinal CAs
- MACRO: goes down to 1:1 magnification (beware: not every Sigma lens designated "MACRO" goes down to 1:1!)
- EX: professional quality
- DG: Good for FX/FF-bodies, works on APS-C/DX-bodies too.
- OS: Image-stabilization, like other manufacturer's VR, VC, IS
- HSM: Hyper Sonic Motor, like Nikon's AF-S works with bodies that lack an AF-drive - and should be pretty silent when focusing.

But:
- it has a list-price of 2099 EUR (incl. 19% VAT)
- it has a size of 95 x 204 mm and weighs 1640 g
- it needs a 86mm filter

Is it really a worthy alternative to the Sigma APO MACRO 150mm F2.8 EX DG OS HSM HSM than is only 17% shorter in focal length but costs only half, has a size of 80 x 150 mm, weighs only 1180 and comes with 72mm filter-threads?

While I haven't checked the exact spec for this lens, in general 180mm macro lenses tend to get a nice boost in working distance over 150mm ones.

it's 47cm vs 38cm MFD, but deduct 54mm for the longer lens and you end up with an extra 36mm working distance.
Is this worth 1000 EUR?
