Canon to release an RF 5.2mm f/2.8L next?

[entoman]

Bet it is a 15mm?

Highly unlikely, as Canon already have the RF 14-35mm F4, and have only just released the 16mm F2.8 pancake.

Nokishita rarely get it wrong.

So two obvious questions remain:

Is it a crop sensor lens?

Is it intended as an astro lens?

Would there be a problem with the sensor getting into the edge of the picture?

Not quite but your hands will be in it, even if you don't put your thumb in front of the lens.

I have the Canon R5 and various RF lenses. I also got the EF 8-15mm f/4 fisheye lens. With the R5 the view is NOT a fully 180 degree view but I have t slightly crop a bit in order to avoid black corners. The image is intrigued but I can use it very seldom only for special "curvy" effects. I am NOT sure what a lens like a 5,2mm lens can do with my R5 camera and the cost might be huge! (the EF 8-15mm cost me less than 700 USD used). Not bad....

I had to read carefully. At 15mm you don't quite get full frame diagonal corner coverage. As if the lens was designed to get the 180 degree diagonal for slide frames and prints with negatives in holders? Except that the lens was released in the digital era. Odd. (I understand you get a full circle at 8mm).

My experience was with the big (not giant) Nikon 8mm f2.8, and I did a youtube video of my own first time unguided disassembly, cleaning and restoration.

Don't forget the EF 15/2.8.
edit to add: @dcsimages beat me to the punch

The EF 15mm f/2.8 was released in '87,well before Canon's first DSLR.

A lens for selfies without reversing the camera? Nikon made a much sought after 6mm lens . Here is a photo, just so we can put it in perspective. $5,000 , $10,000 or more?

Hmmm
I have a 15mm EF full frame fisheye in my case right now.

Yes, I have owned 2 or 3 of them over the years, sold them and then bought another when I spotted a good deal. For the price on the used market, they were a great lens. I ended up keeping my Tokina 17mm f.3.5 which is wide enough for me. I never took to fisheye images.

True. It was first released in 1987, but it was made (available) during the DSLR era. It was discontinued in 2011 I believe.
My shooting buddy has one and I've used it a few times (film as well as digital). It's decently sharp, with just a tad of red/green fringing. We've used it to shoot Milky Way shots. That's where the f/2.8 comes in handy. Unfortunately the 8-15 is only f/4, as well as being very expensive.

There will be an RF firmware update...
Like the R3 eye calibration, the firmware teaches the camera how to recognize your feet and automatically crop them out of every shot!

Finally, something wide enough for wife portraits. I haven't seen her all at once in decades.

Reminds me of a neighbor speaking of his wife. "is this all mine?"

Yeah. I don't see it as wide angle. More like wide load.

The product name of the new Canon lens was confirmed with "RF5.2mm F2.8 L Dual Fisheye"

I'm not sure I understand. I just slipped the 8-15 on my R5. No black corners at 15mm.

Just so people understand, the 8-15mm was designed to be used by all three sensor sizes then available, APS-C, APS-H and Full Frame. On full frame it goes from the classic circular image to a cropped image that fills the frame. There are markings on the side of the lens for APS-C and APS-H. APS-H lines up with 12mm and APS-C lines up 10mm (approximately). There is a zoom limiter that prevents you from going below 10mm if you activate it.

It's a fun lens, but I don't use it all that often. I usually take it to a basketball game once or twice a season and shoot from behind the hoop to get a couple of fun shots. I've also used it to get a picture of a small flower in the foreground with the college's main building in the background. It's best used sparingly and I doubt if I would replace it with an RF version, but it's one lens I will keep even if I sell most of my EF lenses.

Here's a 4.9mm fisheye built by Lens Rentals founder Roger Cicala which has a 270 degree field of view:

This will be a expensive lens, like the Nikkor 6mm f/2.8 from 1972.

Perfect if you want to take a photo behind you, but you do not feel like turning around

Peter McKinnon will strap this to a drone.

Yes, he will

Unfocused stated what I was thinking, APS-H. While the world clamors for a crop RF, Canon might just have had the ultimate happy medium all along, right under our noses.

The latest rumour mentions that this has VR applications - any views on how it would be used? I'm also struggling to picture a 'dual fish-eye'?? f/2.8???
