Anyone know the difference between the Oly 21 3.5 and Oly 28 3.5 in term of IQ? The 21 is almost 10 times the price of the 28. At that price, the 28 would certainly be a real bargain if it is anywhere close to the IQ of the 21.
They are pretty close IMO. And you're right, 28/2.5 is a bargain, and I'd say a 24/2.8 too.
But the 21/3.5 has a brilliant IQ considering it is as an UWA. And the 21/3.5 is 4 times cheaper than a Distagon. And if I had $2000+ to spend on glass I'd buy a set of Zuiko 18, 21, 24, 28, and 35 shift anytime.
alexandre you would be fortunate to get all those for $2k (depending on version). Hell the 18 alone seems to fetch close to $1k by itself, figure $400-600 for the 21... And another $500+ for the 35 shift...
I have lens tests posted on both these I think @ www.edsawyer.com/lenstests/
the 21/3.5 is a great little lens. 28 3.5 also!
Search here at FM, there was a big series of tests/posts by Mike Hatam on these a few years back. Good info there.
Bear in mind that these lenses seem to be a little less futureproof than some others: their bandwidth is mostly between 13 and 21 megapixels, not beyond.

Richard, I think I didn't understand you. Please explain to me.
He's pretty much saying that the Oly's in question are good performers on the current high-MP bodies but don't have the resolution to hold up once the sensor resolution starts climbing beyond 21MP.
I had 3 or 4 Oly 21's and was never happy with the IQ. Corners were a bit too soft and distorted for me, plus when shooting into the sun I would get a large, predominant, red, ring-flare that would render the images useless. (I had both non-MC and MC variants.... both types produced the flare. I should mention that none of the lenses were the f2 version)
My 24, 28 & 35 Olys are a very different story though..... Each produce near distortion free, sharp as a tack, no ring-flare images. The 24mm has now become my primary landscape (and stitched pano) lens on the 1Ds2 and I would highly recommend this lens over the 21 when looking for a wide.
I much rather a lens that allows me full control over image elements.
