Upload & Sell: Off
I LOVE this lens! I would ONLY sell it to help fund either a Samyang 14mm or Nikon 14-24.
Here are a few, taken with a Canon 1Ds. I am now using it on my Nikon F5. I haven't ever used the OM 18mm, but I wouldn't ever pay that much for the Oly. I highly doubt it is worth the extra $750. I paid $130 for this lens. This is coming from someone who has had the Oly 24mm 2.0, 24mm 2,8 - Oly 28mm 3,5 - Oly 50mm 3,5 Macro - (50mm 1,4 and 1,8 as well) Oly 35-70 3,6 and a few others, lol.
I remember that when I bought the Tokina last May (2011), I posted a thread here on if the Tokina would be as good as the Oly 24mm 2,0 as it was a superb lens itself. I tested the two lenses, and the Oly was sold.
