Yeah, the 16mm lens is the lens people love to hate, but thanks to David, I gave it a try and found it pretty useful. I recently got the .75 converter, making it a 12mm lens. Now, I've not had anything this wide before, so I'm still trying to get used to it! Not sure how best to use it, but I'm trying.http://www.computingbits.com/gallery/12 ... _small.jpg
(sorry, can't imbed due to forum limitations!)
What's annoying is that I forget which photos I took with the converter and which without, so some of what I think may be 12mm photos are really 16mm.
Oh, and I was getting moire artifacts, once I processed from RAW, so I don't think sharpness is a problem, through most of the photo. The corners, well, let's hope you don't have anything important there!!! Corners are pretty sad unless stopped down a lot. BTW, I find that the RAW processing is even more important with this lens. The CA is kind of noticeable, but I think the whole image sharpens up with post-processing the CA. Nothing's perfect, but if you can live with a bit of imperfection, this seems like a great bang-for-the-buck combo. How are you going to beat it? With something larger and a lot more expensive, probably!
