I haven't done any astrophotography for a while. The f/2.8 aperture is pretty ordinary and I would probably go for the Voigtlander 10.5mm f/0.95 and shoot at around f/2 instead but that is more due to the ability to frame the image with the faster aperture when wide open.Peter B Photographyhttps://www.blogger.com/profile/00252004358552658781noreply@blogger.comtag:blogger.com,1999:blog-976694674031971613.post-60949717081065642712015-07-17T09:53:39.441-07:002015-07-17T09:53:39.441-07:00Hello Peter,

That means you cannot use it to fit adapters for 4" Lee and Cokin style filters.Peter B Photographyhttps://www.blogger.com/profile/00252004358552658781noreply@blogger.comtag:blogger.com,1999:blog-976694674031971613.post-41509952412765734402015-07-07T02:40:18.579-07:002015-07-07T02:40:18.579-07:00"There is an 88mm thread inside the filter.&q..."There is an 88mm thread inside the filter."<br /><br />Do you mean to say there is an 88 mm thread integrated into the lens hood?Anonymoushttps://www.blogger.com/profile/16162030264650649735noreply@blogger.com
