Having read the reviews on this site I decided I needed either a Panny 14mm or 20mm to get the most out of my new E-P3. I had reviewed the Oly 12mm too but had convinced myself it was too expensive and I could get both Panny lenses for the price of the Oly 12mm and it just didn't make sense. Well, unfortunately, the Panny 20mm was nowhere to be found in the mall but I did find the 14mm. What a great little lens but the asking price was almost $400 (way too expensive). The Oly 12mm was just sitting there on the shelf calling to me and before I could say anything the assistant said "I can offer a special deal on the 12mm". Before I knew it it was on my camera. WOW...I loved it. It felt so solid and the focus so smooth. I took a couple of comparison shots with the 17mm, 14mm and the 12mm. The detail and contrast were vastly superior on the 12mm. But most of all it just felt right. For me nice equipment inspires me to use it more so I knew I had to have it. sure I could buy the Panny 14mm but I just knew I would be more likely to carry that 12mm everywhere and ultimately get more use from it. So, I'm now the proud owner of the Oly 12mm and despite the impact on my wallet I love this lens. (Btw the price in KL was $850) So my advice. Be careful. If you test this lens you'll want to buy it so you better get your story well prepared for how you explain it to your wife.
