That was very informative Gordon. I'd always assumed that the shorter flange distance of mirrorless cameras would make it easier to build true wide angle lenses rather than the retrofocus designs we had for SLRs, but I forgotten about the problem of keeping light rays as near to parallel as possible to enter the sensor wells. I remember this problem gave Leica problems with their M8. Interesting to see how Canon have approached it.

Lens adjustment collars - stuff of nightmares for fixer uppers 😆 People give PMO hard times, but majority of everyday optics have been using it for dacades, from corrective glasses to lasers. My disappointment is that this material has not been taken advantage of enough, and yet we are already suffering from too much plastic rubbish everywhere. We could have had laminated heated elements to prevent fogging up and fungus residence, we could have had in-glass filtering from ND to grad to colour, we could've had internal tilt&shift mechanisms - all of that could be implemented in the "entry level" lenses because of what PMOs can accomodate. Good video Gordon, nice to see Canon recognises your work and your balanced stance on many product reviews. Cheers! 👍

It's very interesting that you were able to do this, given Canon's obsessive protection to date of its patents and access to same. Perhaps a change in strategy? Now time to let everyone see the quality and where those R&D dollars have been going. Also maybe the first step toward allowing more third parties in - which we are hearing more noise about now. Regardless of the motivation, this was a fascinating video and exactly the right person to bring it to us. Thank you, Gordon.

at first glance, plastic elements made me worry, but then, as you mentioned that Canon had been making kit lenses with plastic element since 18-55mm EF-S IS STM, a lens I have used on Rebel series. It's not that bad, although very soft towards edges camparing to the original 24-105mm L. However, I have to say that considering pancake lenses would not be heavy anyway, it's more like Canon treating those RF pancake STM lenses as the Rebel EF-S STM line, the most budget friendly lenses mounted on Canon bodies, cost even lower than the DG DNs from Sigma.

Very cool and interesting to see all the changes and also readons why. One thing i think also gets forgotten that often correction profiles are used to „fix“ the image and often this is the reason for a corner unsharpness in cheaper lenses. However, if someone neets PERFECT corner to corner sharpness, he is using the wrong gear. Its often crazy how much they correct with a profile but also crazy how good the corrected image still looks. As someone that often goes on photo hikes, i certainly do apprechiate lighter gear. Like im not going to take my 50 1.2 on a 15km hike 😂

So at the end you said what I've been thinking: How is this not a great camera for most purposes? The answer, of course, is you have to go back a bit in time, where you couldn't play "Where's Waldo" with the image, looking for some small part of the image you can use. 24mpix still allows some latitude but the confidence to compose a bit on the fly is more needed. Offered in exchange for better ISO, less of the mirrorless quirks, and a better ability to capture that one moment in time, I'm not sure that's a bad trade-off. I've never owned an R5 however. If I had, perhaps I feel differently. Love being able to tease an image out of 30mpix. Maybe I'd be addicted if I had 45 to play with. Still, quite a camera in that R3.

5:20 That is an example how new technology often is first used in cheap compact cameras as the requirements are not that high.

That was interesting! The aperture actuator seems to be a plain 2-phase bipolar stepper, like the focus motor, judging from the 4 fat traces leading to it on the flex. I'm not sure how they're being driven though, unless there's a forest of mosfets on the back of the PCB it's clearly not an H-bridge

All mirrorless lenses today, especially smaller ones, use software profile corrections, and the smaller and wider ones tend to be more substantial.

Canon only out the clicky ones on bigger lenses with a separate manual focusing ring.

Of all those lenses I listed in the video, I think they share a similar rendering characteristic which isn't as attractive as the best glass models I've tested BUT that may be down to more than just plastic vs glass, as the modern glass L lenses are considerably different in every respect, it's not just a material difference. I think if they deployed plastic elements in some high-end lenses, we may have a different view, but right now, they're being mostly used on budget lenses which won't be as good for a number of reasons.

Plastic layered asph lens elements are far from being specific to Canon. They are used a lot in lower end lenses like Nikon Z 24-50mm f/4-6.3, Sony FE 12-24mm f4 G and Fujifilm GF 45-100mm F4. Tamron (also Nik-mron) 70-180mm f2.8 has 2 plastic layered asph elements out of 3 asph elements. You have hardly heard about them because plastic layered asph elements are considered the cheap alternative and manufacturers always attempt to vague them into just "aspheric element". With that said however, are you sure all the asph elements in RF 28mm f2.8 are plastic layered? At least the rectangular ones look like pure plastic. If they had a glass base, then cutting the glass apart would be equally difficult as cutting a regular glass element. There would just be no such need to spend the extra effort cutting them into a rectangular -- unless they are purely plastic, directly moulded from hot resin.

@@cameralabs Longevity might be an issue with plastic, it's really nice to be able to buy a 50+ years lens and it just work. But maybe there's some super stable plastics, I don't know.

Strange that they release it too late for us to take it with us on summer holidays. Looks like a perfect travel lens. We would have bought it instantly if it had been available now.

It would be good for travel

Hopefully the plastic is better optically than that used in Specsavers specs. I wear the glass ones all the time, despite significant extra weight, to avoid the vastly inferior chromatic aberration performance of the plastic.

It's interesting, I also notice optical aberrations on not just glasses, but the lenses used to make TV shows and films! Once you know what to look out for, you can't help it! Ultimately I expect there's different grades of plastic and moulding depending on cost.

Exactly the insight I was looking for, thank you! interestingly, the (non L-series) RF 35mm 1.8 lens was not mentioned to contain these "plasticky" elements

I can guess, if the last 6 months has been any indication... - a max aperture of 3.5 to 7.1 -No hood included - Plastic mount maybe - Not a sliver of weather sealing - Easily scratched cheap feeling brushed plastic - Reduced performance if it is a new version of a previous lens = How depressing. PS - RF 50mm 1.4 when 😡😡😡😡

We already know the aperture is f2.8. And the mount is metal. You can see both in the video, as well as in my preview of this lens. And like all Canon lenses so far, if it isn't an L lens, it won't be weather-sealed or come with a hood - that's just their strategy, not just for the last six months, but for years. And as you'll know from the video if you watch it, it is a completely new design - that's the whole point of the video. So the only depressing thing is a comment that's been posted without watching the video. I do however agree we need a 50 f1.4 and I keep asking for it.

i hate male nails. But as always - great review!

Thanks, I'll ask Shun to wear acrylics next time.

It is cool but it isn't a big secret, I am sure all camera companies buy each others' lenses to have a look inside.

@@cameralabs true. It soon will be though. Aside from Chinese manufacturers, nobody is going to retro engineer it and it seems that Chinese manufacturers haven't tried to hack into Canon's system to make AF lenses that will work with R cameras.

@@cameralabs also at the moment Canon really needs lenses quickly because as an R5 owner who doesn't want all L lenses for both weight and budget reasons, there is almost nothing to choose from aside from adapting EF lenses... And the few good choices are either not weather sealed or have tiny tiny apertures. Canon users need Sigma, Tamron and Tokina to shake up things. At the moment there is really nothing I want to buy to add to my 24-70L, 16/2.8 and 50/1.8... especially with Tele lenses but also wide zooms. I am actually ok having just 3 RF and canon EF/sigma Art EF for now because I want to buy but can't find anything in the range that I want to buy.
