Thinking of something narrower: Panasonic 42.5 F/1.7, Olympus 45mm F/1.8 or Sigma 30mm F/2.8

I put my camera at 30mm with the 14-42 and I like it, at 30mm it's a little more than a stop slower than the Sigma 30mm F/2.8 which is significant. I would be using it when I wanted a slightly tighter crop and for portraits. I think having some background in portraits is nicer than an 85mm or 90mm portrait which is basically only the person.

Unless you back up.

If the Sigma was just a bit faster I'd buy it tomorrow.

Yeah, f2.8 on APS is OK, but on MFT it seems a bit slow. Still, the price is right. The only alternative I can think of is Panasonic's new 30mm f2.8 macro, but that costs $360.

Even if its negative space the 60mm frame is nice.

That's 30mm, or 60mm equivalent. Argh, my brain hurts again.

I have the 19 and the 30. They are very sharp and fast. The 60 is supposed to be the sharpest of all, equal to the PRO-level lenses for Olympus and Panasonic. For the low price, how can you go wrong? Sharp from f2.8; that's OK.

"What you don't see from the specs on these lenses is the quality of their images. They are superb. Google around for some comparisons. Sigma colors are rich and contrasty, The image pops off the screen."

"Do you know how they autofocus? Is it as fast as the panny 20mm?"

"I heard they are much faster than 20mm."

"This is good lenses for practical tasks, like corporate and interviews. Sharp from F2.8, and you really do not need more. Cheap enough to have full set."
