Is there any clear, known technical reason why this would only work with RF lenses?

No

As I said above, the math doesn't work for binning, so we may finally see scaling from Canon for video in a still camera.

I wish I were as bullish. We know the sensor resolution will be 6960X4640, and 6960 is almost exactly 5/3 of DCI 4k. Maybe it's completely coincidental, but that indicates some sort of line skipping or binning scheme to me is at least on the table. Except of course that you'd be skipping 2 of every 5 lines and because of the bayer array that would be two consecutive lines, which would for sure mess with tonality and cause aliasing. Unless there's some way of binning instead...

I don't think Canon has technology to suddenly leapfrog everyone else. Their cinema cameras are enormous, big fans and big batteries, etc.

I'd be satisfied with binning, though. Just yesterday I decided not to buy a new BMPCC 4k and I'm sure the 90D won't even approach that camera for image quality, but a weather sealed (even moderately weather sealed) hybrid would make more sense for me.

Not usually loud to the birds when using a 600mm lens. When I had Canon's 400mm, the birds never seemed to mind the shutter. If I was close enough for the shutter to bother them, then they were probably more afraid of me. Canon needs a cloaking app.

Click to expand...

On an near lake with an large bay, where most birders are taking their shots, the shutter sounds are loudly hearable on the ohter side of the bay (500m away). And on the days, where there are just visual-birders with spectives, more than 4-5 times the number of birds are here. The birding hood is visually camouflaged, so the birds do not see us. The local birdiers club told a lot of photographers to use the silent shutter - that works and keeps a lot more birds from flying away. But some photographers still do not care about being more silent. And on these days, just a few birds stay in the bay.

Eco mode is half the solution: turns lcd off in less than 10 seconds.

In any case I'm shutting down the camera when hanging: I have found out that hanging on my neck causes a huge drain as EVF stays always on.

Same here.

If I have to decide the topic is more important to me than the gear.

Maybe I should use crossposting to increase my # of posts here

Canon 5D Mark III
50-60 year old Super-Takumar 105mm f/2.8 (manual focus)
It's a great old lens with lots of "pop", I think.

A very natural picture of a playing child, well done!

I am completely surprised that the 85 SP does not get more accolades. It is a marvel of a lens, I liken it to my 135 f/2L. The color, the contrast, sharpness and amazing AF speed and accuracy for a 3rd party lens. If the 35 1.4 is better as they say, it will be a giant slayer (EF 351.4L ll)

Click to expand...

I have both the Tamron 45mm and 85mm 1.8's and they are razor sharp and awesome lenses. Both are my two main primes and the 45mm is almost always on my main shooter. It would take a lot for me to replace either one.
The 45mm is so good I'm not even interested in Tamrons new 35mm. My 45mm turns into a 35mm simply by taking two steps backwards! lol

ADDED: Plus I wouldn't want this new 35mm simply because it doesn't have VC.....

Beautiful picture, Glenn.

Sorry, but I think DXO testing isn't even worth a single comment.
We all know the RF 1,2/50 is a fantastic lens, so, why care about DXO ratings?

Do you own the lens? Still not a lot of especially helpful sample shots easily found on web.

I feel like, but have no evidence to prove it, that Adobe may have improved some of their algorithms or something, because I would swear I am getting less noise than I was a year ago from the same cameras. Maybe just my imagination though.

Using lightroom, you can choose the processing engine, so take some 5 year old shots and reprocess them with the later engines. I was able to reprocess some old shots and have what I thought were much better results. I've played with it a little, the difference from process version 1 to 5 is dramatic, but with careful tweaking, that difference might be reduced.

Very Cool.

Thanks!

Ok then I will not modify the sharpenss in the EOS R menu. Thanks!

To put it in as simple terms as you can understand: a GaAs "pathway" is only 3 times as fast as a Si "pathway" of the same size.


The maximum GaAs wafer diameter actually available on the market is 4".

But keep dreaming.

Somewhere below the speed of light is the intrinsic limit to electrical conductivity (i.e. some atomic level energy transfer function in a physics lecture which I can no longer remember!) Obviously you know something about electrical engineering way beyond my level, but a waveform is a waveform is a waveform!

It has a peak, a crossover point and a trough! The amplitude (Y-axis) and horizontal spacing (X-axis) between those is the definer of a logical ON or OFF. A given clock speed is only an indicator of how many of those peaks and troughs I am counting in a second to form a SERIES of bits which are concatenated to form a user-definable set of bytes and then aggregated into commands and data values. Ergo, the higher the clock rate the more commands/data I can fit (minus ECC/CRC/etc.) in that time period. A Two Terahertz clock speed is NOWHERE NEAR the limit of energy transfer within an electrical conductor which forms the basis of a waveform. The only issue is inherent noise floor which makes it tricky to figure out where "bitwise packets" begin and end, the higher the frequency you go! It's a processing of creating high purity traces that don't block as much energy transfer OR allow a more discernable series of "pulses" to be passed around.

Again, I'm NOT an electrical engineer so I don't know much at the truly low-hardware-level of HOW they do that sort of DSP to be able to discern and cleanup an electrical signal that has 60 Billion and Two Trillion pulses a second! THAT is a level of electrical hardware engineering that is TRULY WORLD CLASS !!!!!!!!!

This company has THEIR OWN wafer making capability in BOTH CMOS and GaAs and GaN. It's 200mm by 200mm chips!
I see them every day! TOO BAD SO SAD !!! They ABSOLUTELY HAVE the Quality Assurance technology to ENSURE line trace integrity and doping quality over that large of a substrate! I should note that to etch a chip that size on an Ion beam/Electron Beam etcher is a SLOOOOOW process which is WHY only 1400 of each type of chip has been made! Think of etching rates that says it takes OVER A MONTH to make each chip! Think of how much it costs to buy enough etchers to take over one year to make a mere 2400 chips. I think they actually BOUGHT the entire company so they could force all etcher production to be sent to the parent company! Hint: It's a lot of money! Think of the automated and customized optical scanning technology they had to buy to do quality assurance on that large of a wafer!

In research labs, I've seen researchers that are doing 600 mm wafers in CMOS now! GaAs and GaN is not that far behind at that 600mm size! You've been living in a cocoon! You probably subscribe to Electronic Design and Microwaves & RF magazines !!! Goto some of the symposiums listed therein! It's here NOW! 80 GHZ and 100 GHz is nothing these days! Two Terahertz is starting to mature out of the labs and 4 THz is coming online soon! Go fully opto-electronic and we are into Petahertz+ ranges! This is NOT NEW NEWS !!! Read up on it!

And I should note the designs are PARALLEL and Synchronized so that numeric, string or pixel data gets processed on a specified time schedule and then the results are pushed out within predictable time period for external workstation-level processing/visualization. We care about GROSS AMOUNTS of data packets being processed in parallel on a specific schedule. We don't actually NEED linearly fast individual bits/bytes processing just massively parallel SYNCHRONIZED processing! Remember! We are outputting image tiles that are 128-bits per pixel (RGBA + metadata channels) at 65,536 by 65,536 pixels in size to be filtered and presented on a 64-bit RGBA colour laser projector that can do up to 10,000 fps to visualize neural tissue interaction in real-time!

WE are the ONLY ONES in the world that can do that sort of processing in real-time! Ergo, the parent company built the world's FASTEST supercomputer and LARGEST 64k by 64k resolution multi-RGB-Laser projection system with completely in-house custom-built GaAs 60 GHz and 2 THz clock speed super-chips!

Not even the NSA/DARPA has THAT sort of compute technology!

It's here NOW! We have it! Deal with it!

Only you know what you are supposed to get excited about. How is anyone else supposed to know? Careful of the carpet. Don't wet yourself, Skippy. You weren't waiting for this and aren't a buyer anyway, right? So no point.

How about an RF mount combo digital sensor/film body? That's one no one has asked for...

I am in limbo waiting for a "new" M system camera to come out. The current are a bit long in the tooth (except M50).
I can't afford to buy a new one next year just because the 'aggressive price and features' makes the next Mxx? way better than the M50 I bought this month.
Same goes for rumoured updated M-lenses. There are some good EOFY sales on now, so I was considering buying a lense at least.

Click to expand...

My two requirements for a new M were "Hot shoe", "No EVF" and "Eye AF". But I now have an RP to use for macro with flash, so the requirements are now just "Eye AF" and "No EVF". I hope the Mxxx version is good enough and cheap enough so I don't have to pay a lot after selling the M50.

I'm still hoping for a revamped original M, that one was built like a tank.

Thats normal and its worse for big lenses. If you look at the back of your lens where the lock pin fits, its a oval and not perfectly round. Its done that way to handle tolerances, and depending on how the two parts match up, there may be some play. Don't worry, its normal.

maybe the industry is slow as shit. we barely get big technology breakthroughs but they still charge a lot for cameras. cellphones are evolving by the second especially on the photoside and it isnt all about sensors. its about software ans sensors and options/features.

Great shot, Glenn.

Possibly, but it's very unlikely. Especially considering it's 720p. Not a lot of people use the 120fps from the R, but it is a high bitrate and actually looks decent upscaled to 1080p. If they did every update it with AF I would probably use it more.

Click to expand...

Exactly, I like the quality of images it produce even in 720P 120 fps that is totally usable to upscale in 1080P. I just wish that they update AF in that mode

so far, there has been no evidence that ef-rf adapter affects image quality of adapted EF lenses used on R-series cameras. not a slight sign of vignetting levels being affected by the adaptor.
