Canon plans to develop more lenses that no one has done before

[whothafunk]

I always wondered why is there no consideration towards 70-200 f2.5, or 300 f2.5. If they went 135 f2 to 135 to 1.8, why not 70-200 f2.5? Why must it be a full stop for specific lenses?

My hope is that Canon will keep up the good work on their lenses. The 28-70 2.0 is a great example of how it should be done. Some reviews end with con's like heavy and expensive, those lenses are the best.

And prices we've never seen before too!

Vivitar series 1. They did wacky things like that.

Why wouldn't it? An RF 70-200mm f/2 would be almost identical in dimensions to the RF 100-300mm f/2.8 and could share many parts. The RF 100-300mm f/2.8 has an entrance pupil of 106mm (what I calculated) and a filter size of 112mm

I think the size of the 100-300 wouldn´t fit one of the main intended use cases of such a lens very well: the ultimate event style portrait lens. I don´t see many photographers carrying one of those around all day, especially not with a second body + lens for wider angles.
But there are a lot who carry the 70-200mm 2.8, and I can imagine many would trade that in for a 70-135mm f2 if it was similar in size and weight.

Sigma had a 180mm f/2.8 macro and launched a version with OS just before they announced the global vision line.

They are hard to find on the second hand market in .nl, so I assume people are happy with them

You are right on the 180mm, I was only thinking about the Nikon 200mm f4 macro.

 

[davidj]

20mm is pretty much the flange distance, which complicates design.
Sticking to 24, but maybe extend to 120 seems easier to achieve.
After all, Nikon is successful in these.

While I used both systems side by side, I'd use that quite often
on the Nikons.

Sony have a 20-70mm lens.

...how many \'decent\' Canon-branded EF-S lenses were made?

17-55 2.8 IS? Others? 15-85 3.5-5.6?

If past is prologue Canon will not manufacture all that many RF-S \'enthusiast\' lenses.

FYI: I\'m having difficulty accessing the Forums here on CR. I hope it is just me?!

All of the EF-S primes were decent.

 

[EOS 4 Life]

I had first had that on the article, and then realized with a 100mm front element, that it's simply not ever going to happen.
which is why i changed it to be a 70-135mm

There are patents for 70-135 f/2 IS and 70-150 f/2 IS.
The RF 100-300 f/2.8 is an indication that the size of the front element will not deter Canon.

 

[EOS 4 Life]

A 600mm F4 with built it 1.4 TC please at under 3Kg.

600 f/4 x 1.4 has been done.

 

[EOS 4 Life]

As an outdoor portrait photographer, I am dreaming of a RF 105mm F1.4. Bokeh, bokeh, and more bokeh.

Get the Sigma.

The biggest issue I have with the 28-70 is the clicky AF noise.
It can't be used for head shot interviews for that reason.
A V2 version with silent motors would be great.

No, the opposite.
Sigma did not make very many because they were not very good.

RF 14mm F1.2L with excellent aberration control would have a lot of people jumping up and down

YES PLEASE!

I wonder when the rumored RF15-35 Z will see the light of day. Hopefully 2024 or early 2025.

Also, I feel like the RF 24-70L f/2.8 from 2019 is due for an update to perhaps make it a little more compact with similar or better IQ just like the original RF15-35L. The RF35mm f1.4 is far from perfect so hopefully the RF24mm f/1.4 is a little better optically!

Wondering if they'll announce it with the R5II.

With the new 35mm VCM we learnt that "cutting corners" takes all it sense.

The corners do not seem any darker than the RF 50 f/1.2 L or RF 85 f/1.2 L.
I was hoping for better but people blaming digital correction over optical are misplaced.

 

[Kokabiel]

They can do anything now that lenses are digitally corrected. What would impress me is shrink the lenses back to what they use to be pre DSLR.

 

[Del Paso]

Sony have a 20-70mm lens.

Which is not very good...

 

[neuroanatomist]

Halo lenses like a 1-100mm f0.1L are now possible now that Canon has mastered the art of digital yoga, stretching an image from apsc coverage+black corners into full frame.

It's cool to do stuff that no one has done before but please stop that bs please? Digital corrections are fine, until you go overboard in *cutting corners* with the optical design.

Hyperbole aside, the fact is that any wide angle, rectilinear lens must have the corners ‘stretched’. In film/DSLR days, the only way to do that was optically, and one need only look at the mushy corners of the EF 17-40/4L to know that optical correction of barrel distortion is not the ideal you seem to think.

The reality is that neither optical nor digital correction is inherently better. Digital correction allows lens designs that weren’t previously possible. The RF 14-35/4 uses 77mm filters and after correction at 14mm it’s just as sharp in the extreme corners as the EF 11-24/4 at 14mm, even though the latter has no barrel distortion at that point. That’s a big win for digital correction, in my book. The RF 10-20/4 is also as good as the EF 11-24/4 in the corners, and the former is wider, cheaper, and much smaller and lighter. Another win.

If you want to forego technological advances, best go back to shooting film. Or get a sketchpad and some pencils.

 

[Aldherrian]

With unusual lens focal lengths, I wonder if they would explore some more high grade lens on a "all-around" lens like EFS18-135/RFS18-150 that essentially only get mid-grade optics for kits
Something like 18-135 F4.
I guess, so far getting better optics in such wide range would get a bit too big for the purpose of a do-it-all lens for travel but I wonder if that would still be the case now.
In the FF realm, the 24-240 which serves the same purpose doesn't seem that well received either

 

[bergstrom]

EF-S 60mm is one sharp lens.

Maybe they could bring out a 24-105 f4 ii and take back all the mark 1 ones that are soft on the edge, that people had to pay good money for.
