The 10-20mm F4 and 20mm F1.4 above are a couple of options (Image credit: Future / Tim Coleman) The mystery ultra-wide prime could have a f/1.4 aperture It could be Canon's widest prime lens for mirrorless yet There are no details of an expected launch date yet Canon is tipped to fill a long-time gap in its lens lineup, with a completely new ultra-wide angle prime that could be perfect for astrophotography. Leaks about the lens are seemingly few, but that hasn't stopped Canon Rumors from speculating what the mystery full-frame lens for Canon's mirrorless camera might be – and it could be a world-first. Judging by the response to the post, such a lens could be a big hit with Canon and astrophotography fans. Here's what has been rumored so far.

(Image credit: Rod Lawton) An all-new, world-first prime Canon has launched plenty of superb lenses for its mirrorless cameras, however, ultra-wide angle fans are short of options. There's the five-star RF 10-20mm F4L IS STM zoom and a hybrid RF 20mm F1.4 VCM, but no wider fast prime like Sigma's 14mm f/1.4 (for Sony E and L-mount only). That could be about to change. Arguably the most significant detail about this lens is absent in Canon Rumors' post: focal length. There's speculation is could be a 14mm lens, or even be as wide as 12mm. The leaker seems more certain that the maximum aperture is going to be f/1.4. If it's going to be a true world-first lens then, it couldn't be a 14mm f/1.4, given Sigma's lens. However, it could still be, with various qualifiers. Get daily insight, inspiration and deals in your inbox Sign up for breaking news, reviews, opinion, top tech deals, and more.

Whatever the case, if this lens materializes, it sounds like something totally new for Canon, combining an ultra-wide perspective with a bright maximum aperture that's ideal for low light work, such as astrophotography. Naturally, a professional L-series lens like a 14mm f/1.4 will be a chunky thing. However, I'd expect it to be smaller than a DSLR equivalent; Canon has previously been able to reduce the size and weight of certain DSLR lenses when making them afresh for mirrorless, such as the 10-20mm F4L IS STM, which was half the weight of the EF 11-24mm f/4L USM. And while Canon has recently focused its efforts into hybrid VCM lenses designed for photo and video work, the feeling is that this rumored ultra-fast prime will be an STM lens, better equipped for photography. Such a lens is one of the most requested from Canon photographers, who hopefully won't have long to wait.
