Just because it doesn't say 24fps (at this point) doesn't mean it wont be there. It will be in the R5. Just wait for the full announcement in a couple months.Video noob question. When I see a listed spec like say 4k @ 30 fps no crop, I often see wishes that they also have 24 fps. Isn't 24 fps easier to do than 30fps? Why wouldn't the slower fps always be an included option if its something so in demand?
Another point indicating suggesting I should reconsider my non-use of sun shades!
But seriously, how many hours of direct sunlight does a lens element receive compared to, say, an automotive headlight?
In the telescope world, we but a scope and intend to keep it for a lifetime, knowing that the coating efficiency will decline in the early years. (And we might even be paying a premium for enhanced coatings that can't be recoated.) If a sideline sports pro sees a virtually undetectable 10% light loss in 10 years of active work, that seems economically minuscule.
Very good. but Acryllic will go yellow in 3-5 years from new due to UV exposure in outdoors resulting in yellowish tint on images taken with your super lens. Harry. this is not a good idea..

Some really high end German-made CNC machines get down to 0.0005 of a millimetre or even better on any 3D-XYZ axis so it's getting better by the year!
In terms of polishing you can now automate it to such a degree, that laser-interferometry can now be used to gauge perfect curvature and/or flatness on a lens and repeat that perfect dimensioning over-and-over on EVERY lens in the production line. You need to "dope" the Acrylic or Polycarbonate with other elements in order to reduce "glass creep" and expansion/contraction issues BUT it is now possible to create in 2020 a high quality video and stills photo-centric lenses that are ON PAR with and even outperform fluorite glass elements. They will definitely be half-the-weight! The science of anti-scratch, polarization and anti-reflective surface coatings is what brings up the "plastic" lenses to glass-lens potential.
Again, a company like SIGMA definitely HAS the ability to make Acrylic or Polycarbonate still photo and cinema lenses... they just have to spend some money on the CNC machining technology and coating technology!
I HIGHLY SUGGEST the Kern Pyramid Nano for long-term precision serial production-level machining: (i.e. +/- 0.3 microns variance!) since it can do 500 mm by 500 mm plates of lens material, so that's about 50 to 100 lens elements in ONE RUN at ultra high precision! It would pay for itself in less than three months! Get TWENTY of these machines and SIGMA (or Canon!) could make SUPER-FAST compound curve Polycarbonate/Acrylic plastic lenses in batch-after-batch, enough to fulfill EVERY sales lead!

ALL of the current Sigma Art-series Prime and Zoom lenses would be HALF the weight and about 5% to 10% FASTER than any of their current glass! I would PERSONALLY have no issue to spending the money on a FAST SIGMA plastic lens if it has a decent anti-scratch coating (i.e. thin film vapour deposited sapphire!) AND was even only 5% faster than the glass Art series primes and zooms! The weight savings alone would make them worthwhile!

The R5 will make its public debut at The Photography Show(UK) 14 March.
One question to think about is how many people are ready to jump into mirrorless at the 5 level. Also most potential buyers are going to have pretty good cameras already, so another question is how happy they are with what they have now.

Are you guessing at this or do you have real information?
Fair enough. To be accurate, I should have said people who are happy with what they have already, even with the availability of an R5 at whatever price Canon is charging for it.You ask: "question is how happy they are with what they have now"
I would say that even if someone is 100% happy with what they have, they would still switch if they see innovations they have not not seen before and that would improve their photography in the one or the other way ...

What's the consensus on flicker reduction? It's an option in my RP that I've never taken advantage of. Does it actually work?
Yeah, I have a feeling that the 7DII is going to hold its current value for awhile. Similar to the 1D IV -- which only recently dropped in value on the used market.
