Chris Kippax 43 Posted December 17, 2017 (edited) Hi All I am wondering if anyone has experience using the Canon 24mm F1.4 II behind the Ikelite 8" dome? How does it perform? Is the image sharpness and IQ excellent? How is corner sharpness? Is it wide enough for reef scapes and large pelagics or will it always be a compromise? Will be using it on a Full Frame camera Thanks for your replies. Edited December 17, 2017 by Chris Kippax Share this post Link to post Share on other sites
vbpress 4 Posted January 14, 2018 (edited) One month without response, I'm sorry. I've experience with similar equipment: Sigma 24/1.4 ART in Sea&Sea Housing behind the 240 S&S Dome port (quite different by your 8" dome) mounting the correction lens Sea&Sea CL 77. This is the reason which my experience is less interesting for you (I suppose). I've used 40mm extension ring on my MDX-D800 housing, which is the true important gear to achieve the best possible sharpness corner. In any case my results was very good, but the 24mm DOF is less extended than a very wide lenses, so there are a lot of limitations like in the picture below where despite of f/13 the right side foreground is out of focus. For this reason I prefer 18-17 wide on full frame camera 'cause thy offer wider DOF very useful in this kind of picture. a 18mm shot Edited January 14, 2018 by vbpress Share this post Link to post Share on other sites
