I love 14mm f2.8 and its early version was considered inferior to Da12-24 ...
However, Da14mm f2.8 is so much more versatile in terms of brighter view finder while shooting at night and it is a sharp lens regardless even at the corner wide open.
Speaking of Fish eye, the corners are unfortunately going to be soft ... But the effect is addictive and I love it quite a lot. For travel and hobby, I would consider DA14 f2.8 as a first choice given these options.
Cheers
