1. sharper than nikkor 17-55 under 100% magnification,
2. very close to actual original colour, not so digital as 17-55, which is too exaggerated,
3. light weight when using D3100, perfect match, just one kg in total,
4. turning ring with good intact, which 17-55 turns white when aging,
5. cheap with a 2nd hand price $3xxx.
缺點:
1. under dim light, difficult to focus,
2. too few in second market,
3. a bit soft than 17-55, but good for portriat,
