A tad long for us crop sensor crowd but may make for a nice reasonably fast 15mm full frame lens to capture the night sky. By the looks of it a filter can be installed camera end of the lens so I wonder if this may be compatible with baader filters?? No price as yet though.

Looks nice. But no price release yet. The rear filter slot is for gelatine filters (30 x 30 mm), so probably not Baader compatible. (The only Baader filters that are frameless that I found were 3 mm glass. Gelatine is much thinner.)

I was playing with one of these at the recent Birmingham, Photography Show, I must admit i was seriously impressed. A whole heap of interesting and innovative features e.g. f2.4 rather than the quoted f2.8, indented infinity focus point, focus lock, luminous engraving, weather sealing, 95mm front filter - I was quoted a UK price of around £600 - of course it will be good to see what the coma correction is like, but it sounds promising. They did have another 11mm lens behind glass, I look forward to seeing some hands on reviews...  Main web site link - http://irixlens.com/15mm.php
