I'll be doing more testing and hope to add more details on my blog when I do. <br /><br />Dan - Yes, the CA is horrific at 8mm as shown by the big blue circle around the images at 8mm. It doesn't seem as bad at 15mm, but given the physical shape of this lens and all that it is trying to accomplish I am not surprised. I think there's a good reason we haven't seen a 8-15mm before now. <br /><br />I would suspect the next release of DPP to have some better built-in processing of raw images from this lens that could help to address this problem. We'll have to see.ronmartblog.comhttps://www.blogger.com/profile/06815090271742112506noreply@blogger.comtag:blogger.com,1999:blog-5826231802859523569.post-38032598389709148192011-08-06T18:54:09.492-07:002011-08-06T18:54:09.492-07:00I accidentally deleted this comment post due to tr...I accidentally deleted this comment post due to trying to approve via my phone instead of waiting until I was on my computer:<br /><br />Rob has left a new comment on your post "Mini-Review: Canon EF 8-15mm f/4L USM Fisheye Ultr...": <br /><br />Great review! I was really excited to see this lens tested on a full frame camera. I owned a cheap 8mm Peleng and currently use a Canon 15mm fisheye. In most cases the 15mm is enough, fills the frame but still offers sharp focus. <br /><br />The 8mm would be handy to have for an experimental photos, like the spherical panoramic images.ronmartblog.comhttps://www.blogger.com/profile/06815090271742112506noreply@blogger.comtag:blogger.com,1999:blog-5826231802859523569.post-39040192316732918402011-08-06T17:39:48.048-07:002011-08-06T17:39:48.048-07:00Hey Ron,

I just posted a pretty big review of it on my site http://dancarrphotography.com/blog/2011/08/06/canon-8-15-f4-l-usm-zoom-review/ and I have found that the chromatic aberrations are some of the worst I've ever seen. I must admit that I concentrated more on 15mm (or 12 on a 1d4) because I think 8mm is too gimmicky for the work that I do, but I used a 15mm fish quite a lot.Dan Carrhttps://www.blogger.com/profile/01047867298483543130noreply@blogger.com
