Canon Announces the Canon RF 7-14mm f/2.8-3.5 Fisheye Zoom lens

[Richard-CN]

Canon today has announced the Canon RF 7-14mm f/2.8-3.5 fisheye zoom lens. It's been a long time since Canon shocked the industry with the Canon EF 8-15mm f/4L USM – approximately 15 years ago, and this time, Canon said, we can do better. And they did, they made it wider and faster – and the […]

The MTFs you posted for the discontinued EF 8-15 are old versions, calculated differently, and not allowing for diffraction. Here are the ones Canon replaced them with:



Ah thanks! Was very quickly romping through the internet, pulling it all together this morning / afternoon - and missed the new ones.

Even though the 7-14 is sadly a bit larger than its EF predecessor, it's kinda sexy that Canon managed to keep this lens in the VCM series format. Nice.

Not really, it's pretty much the EF version with an integrated Ef ot R adapter with dropin filters. Very sweet, this is the first RF lens taht can use these particular drop in filters. I hope Canon does a few more UWA lenses with this feature!

Looking at the cutaway view of the new RF 7-14mm, it's apparent that it is a reuse with minor modification of the EF 8-15mm optics (block diagram superimposed), meaning the lens needed the 'adapter' (spacing) anyway...so why not include a drop-in slot?



I was hoping for a drop-in slot on the RF 14/1.4, but clearly there is not enough room as the barrel is packed with glass. IMO, the inclusion of a drop-in slot in a non-telephoto lens means that the design is really not taking advantage of the short RF flange focal distance. I suspect that means we won't see this feature very often.

Comparing the MTF diagrams of the RF lens vs. the EF version, the RF performs much better, and although the optical construction at first sight may look similar, several elements are clearly different (RF: 16 elements, 11 groups, 2 aspherical, 5 Ultra-low Dispersion (UD) vs. EF: 14 elements, 11 groups, 1 aspherical, 1 UD) - which I suppose explains the marked improvement in performance.

Curious, is there a way to use a protective filter? I'm kind of rough on my gear , I need all the protection I can get. I think there is a lens hood, which will help a bit, but does not work if you shoot at 7mm. Also, anyone use this for basketball, love to see some photos.

Protective filter for a lens with 190 degree field of view?

@Richard; " it offers two different flavors of image projection onto the sensor."
Strictly speaking this isn't true. The projection is always Equidistant. What changes is the image circle diameter.

The RF 7-14mm isn't at all close to the EF 8-15mm. Here's my overlay:

The clincher is that the EF is an Equisolid projection and the RF is Equidistant.

Super Happy to see this lens. I really enjoy fisheye and was afraid Canon would not make an RF lens. I pre-ordered from B&H on the first day.

I did laugh a little when I saw the skateboarding photos in the article above. It is OK to shoot other things with fisheye guys. Here's one taken with my 8-15mm f4

I had to google the meaning of your explanation and the words "equisolid" and "equidistant", but it was fun reading about it!: thx

Received my 7-14mm On Friday. Shot this on Sat Morning. First photo with the new lens.
