There are two models of the above lens on the market. The f4-5.8 and the f4-5.6.
Some of the latter are marked as MkII on websites but others not, yet the f rating is 4-5.6.
I've always assumed the 4-5.8 is the older model and ALL 4-5.6 are the MkII even if the markings are different on some which I assumed to be because of kit or boxed versions.
Am I safe in assuming the 4-5.6 is the MKII ?
