Hi, all.

Just got the FZ20 yesterday. I was really surprised by the noticeability of the barrel distortion at the lowest focal length...

Here's what I mean:

,,, mind you, as soon as you move off that length, by even a very small amount, the distortion becomes much less noticeable, as you can see here:

In view of the glowing reviews for the lens, I was surprised... I guess Panasonic is really pushing the envelope with that one. Still, makes me miss my old 28mm Nikkor... (Sigh...)

Please excuse the focus, lack of tripod, etc. Just a quick test to see if my eyes were playing tricks on me!

We've all seen it. It can be corrected easily. If wide angle is what you want there are better cameras for that.:arrow:

Look up "Panotools" in the search box, read thread with instructions. Use if you wish to take 35mm focal lenth close-ups of objects with vertical lines.

I am surprised in the opposite way: did not think that most of the distortion disappeared so soon:

1st shot f= 6mm
2nd shot f= 7mm

How many horizons at sea I have spoiled to stay at 6mm (thinking I should have zoomed in up to 3x to remove th barrel distortion)

Nick, after seeing you mention panotools several times and your great examples of the baristas, I finally decided to get it today (the PS plugin). Man, it's very cryptic how it works. I finally found a website that provided some sample numbers to use and once I got some figures in there, it really did the trick. Great tool but hardly intuitive.

thx dynamohum, that's actually even better than the site I found the information from.

For more reference, here's where I read to find the mystery numbers:
