So, turns out that hitting Command-Return instead of Shift-Return submits the post. Who knew?
anyway, Part Two.
They have smaller apertures.
This might seem to be a disadvantage, but maybe not as much as you'd imagine. Firstly, smaller apertures are easy to focus, so less shots with missed focus. BOOM. You're welcome. Tell Panasonic (or whoever) I just upgraded their AF.
See if you can tell the difference in DoF between these?
No? Well, F2.8 to F3.5 isn't much difference.
OK, let's get less fair.. What about these?
Sure, it's a small difference, but that's a two whole stops. It's also many many hundreds of dollars.
Low light is definitely a difference here, that's true, so the kit zoom isn't really a low-light monster, but these lenses are practically free so you can't have everything!
