Ive just sold my wide end, Right now my widest is 24mm. Im looking at buying the 12-24mm sigma - again... or even the 11-16mm toki. Also been looking at the 17-40mm.
Basically what else is there thats not 1000 +
Basically I was never happy with the 17-40 distortion & Corners, the zeiss 18 have huge flare and distortion probs. the only one I really liked of the above was the sigma but the corners was soft.
Have never tried the toki, or is there something else to consider.



This time I'm not letting it go. If I had to sell it in desperation to fund another lens, then yes.
