Originally posted by pepperberry farm evolutionary changes to the 01B - it now has a plastic covered distance window, the focus ring was changed a bit, essentially just an update...
I have read that the optics were unchanged, but reviewers disagree with that and have reported that they've noticed better shots from the 01BB (I do not have the previous model, so no idea)...
a quick note about the how the 01BB differs from her predecessor: the focus ring on the lens used to be larger and have more of a stand-off from the barrel of the lens; the 01BB, however, has a smaller focus ring and the rubber/plastic that is covered with is actually somewhat inset from the barrel...
I was out most of the day with the lens on my K-3, in the heat of summer, and as my fingers sweated I noticed that the focus ring would become more difficult to easily grip/turn...
an odd thing...
I have several of those lens bands that come with various accessories - I've never needed or used one....
I'm going to test one out on the 01BB to see if that solves it...
