Here are a few early pics from my newest LBA. I did some light editing with Irfanview (that's all I have here at work).
I haven't done much in the way of testing for sharpness, but I love the amount of distortion you get at 10mm. I guess that is what the 'fisheye' effect is all about. I'm still trying to figure out how people can complain about distortion on a fisheye lens...
One thing I did notice was some pretty bad PF in high contrast situations (seen in the first 3 pics). Stopping down a few clicks seems to get rid of it. At F4.5 it's there, but at 5.6 it's pretty much gone. Even though it was very bright out yesterday at lunchtime, I was surprised at how well this lens performed with the bright overhead sun. I did get it to flare in one pic, but even that wasn't as bad as I thought it would be.
10mm @ F5 (some PF around the lights on the right)
10mm @ F4.5 (much PF here)
17mm @ F5
10mm @ F8
I think I'm going to like this lens. As long as obvious the PF situations are avoided, it seems to produce some pretty clean images. While I'm not sure whether the amount of use it'll get justifies its price tag ($399.95 @ Buydig.com), it's going to be fun to play with and I'm sure it'll be useful in certain situations. It's such a unique lens that I know I'd regret not having it if I got rid of it. In fact, it's more likely that I will try to create situations where I can put it to good use. The trick is in not overdoing it......which is easy to do with a lens that's this much fun.
