Ha! No I definitely do not regret it...! In fact if one thing, I am now thinking when/if I should get a wide limited, but I think this will have to wait a little bit... This 35mm Ltd is very crisp and nice from end to end, and I am looking forward to taking more photos with it.

I found that the focusing is super sensitive close to infinity, sub-millimeter moves will blur things up when magnified using the live view. But with a very steady hand, or even better a tripod, it works well...
I did a little bit of more detailed reading re. macro vs. normal lenses, and I can now see what macro lenses are all about. In comparison with the other lenses I have, (kit 18-55, Tamron 18-50, FA50/1.4 and a Sigma 10-20mm), this macro lens is mostly sharp from end to end, there is very little or not at all vignetting at the corners, and the colours are more vivid, with again little fringing.
I don't discount the other lenses at all, but this one seems to be a little bit more 'special'
