I don't really do comparisons as such, but I do notice when a lens produces crispy images with ease and in difficult light.
The FA macro is in that category, but it's screwdrive is noisy and after using HSM for a while there is no going back. The FA also seeks a bit, probably due to the macro-related long focus throw, which makes the noise worse.
I suspect in terms if simple sharpness that the two lenses are very similar, but the HSM silence and speed, and the zoom range makes the sigma the better lens IMO. Of course I'll be using the FA when I go to digitize my negatives, and it's the ideal lens to use with the ring flash I have - kinda bummed the sigma is too big to fit it actually.
Yeah, the sigma is a no brainer really. Just don't drop it like I did, the construction is nowhere near as robust as the FA, and it is significantly larger, so .. yeah.
