Yeah, but June 11th, 2025 would have meant that we already have the camera and the lens in our hands

People like to brag L lenses, even when the lens sucks...it's just "I have a thicker wallet then yours"; you can afford it, and you want people to know you can.

I actually appreciate that

I buy L lenses because of many factors, one is durability. In a professional environment, gear takes more of a beating. I’ve had more failures with Sigma and Tamron than the rest of my L lenses put together. Those 3rd party lenses were sharp and cheap but way less durable. Both brands ended up costing me more money in the long run. L lenses are reliable and dependable, they also hold their value on the used market better too. My EF 135mm f2.0 L I’ve owned for nearly 20 years now. I never missed a beat. Sure, the new RF version is more expensive, slightly brighter, has IS and is a bit larger too…but my old lens turns in such nice images.

Thanks so much for the link.

That the Hubble was imperfect...I remembered.

I did not know why, and did not know that Perkin-Elmer was involved.

=====

As part of my graduate studies, I utilized IR spectroscopy on a regular basis.

The existing device (1980) in our lab was very old...and its innards were very much analog. I cannot find anything online that looks like what I remember...they were wide and tall and heavy.

Our lab had two of them. Finally, they both broke down at the same time.

About 1981 or 1982, we replaced them with a single Perkin-Elmer IR spectrometer, a new design...all electronic.

PE had trouble with these, and their service personnel were in the dark as far as repairs were concerned.

It turns out, across town, that my wife was employed in a chemistry lab at that same time, and they too had these new PE IR spectrometers in her labs.

And the devices in her labs were also problematic.

Her repairman was the same guy that worked on ours (Rodney), the recollection of whom causes both my wife and I to smile.

Remember, this was 45 or so years ago.

And you know how Rodney attempted (often successfully) to repair these electronic IR spectrometers, in both of our labs?

He literally swapped circuit boards...in-and-out...one at a time.

The way you put a graphics card into a PC!

=====

My camera at that time?

A Polaroid and a Minolta, I think.

Minolta? They made the the first mass produced AF cameras as I recall (after Konica). Later it was Konica-Minolta and now just Sony...

Either that, or some photographers understand that the best lens for one use case is not always the best lens for all use cases?

Why choose a portrait lens used in a 3D world based only on how it performs reproducing flat test charts? Even if that flat field correction that gives it superior performance reproducing the edges of flat test charts makes out of focus areas look harsh or busy?

It still amazes me how some people keep buying the lens, even today, instead of the Sigma 50mm f/1.4 Art.

Not everyone buys lenses to do flat document (i.e. test charts) reproduction. The idea that flat field correction is more important than smooth out of focus areas for an f/1.2 portrait prime is misguided at best.

If you want to be the best test chart shooter in the world, then the Art is the lens for you.

The Sigma 50mm f/1.4 Art has always been better than the EF 50mm f/1.2, the only parameter where the 1.2 lens took the lead was pretty much bokeh.

That all depends upon what one means by "better". Flat field correction usually means less smooth bokeh, especially prior to the late 2010s.

Roger Cicala talked about this in one of his blogs a while back.

If you want to do document reproduction (or shoot the sharpest photos of flat test charts) you need a different type of lens than the EF 50mm f/1.2 L. It doesn't matter if the out of focus areas are harsh when your entire field is the same distance from the camera.

If you're shooting portraits in a 3D environment (i.e. not in a studio with a diffuse backdrop), though, smooth out of focus areas are far more important than the edges and corners being focused on exactly the same distance as the center of the field is focused.

What it really means is there is the performance that can be wrung out of a lens if you really, really know your lens. Know where in the image it works best and where it works worst and plan your photographs accordingly. And that, my friends, is one of the things that separates great photographers from good ones. - Roger Cicala February 2020

Michael Clark said:
I notice that you joined Canon Rumors at almost the exact same time another very active member here was banned. I also noticed that you both like to use the same word to describe cameras which you think Canon should not/would not bring to market based on your own anecdotal experience.

I have no idea who you're referring to. I have never participated here under any name other than the one I currently use, and as you note, whoever he was, he was gone by the time I got here. (My real name is in the URL for my photo website which has been in my signature for a long time, by the way - I have nothing to hide. My username is my nickname since college, over half a century ago.)

I do not appreciate being the target of such scurrilous accusations, which are the last resort of someone who is losing an argument.

PS You still have not said which if any R series camera you own - your gear list is still unchanged and only lists DSLRs. Occasional use - if such there has been - does not give rise to muscle memory, so you appear to be going by reference to muscle memory from your DSLRs.

PPS You also have not responded to my suggestions of simply adding another control dial to an R7 II in the standard location next to the rear screen and letting it take a battery grip. You probably know that the menu system on EOS cameras makes it trivially easy to disable the dial around the joystick if it's such an annoyance. Oh, and in case you didn't know, the joystick is a bit of an anachronism now, since on the R series, you can use your thumb on the rear screen to move the AF focus point while looking through the viewfinder, which allows for more fine control than the joystick does. I'll occasionally push in on the joystick to center the AF point, but that's about all I use it for.

PPPS I do not use "unicorn" to say a camera should not or would not be brought to market, merely to refer to cameras that can't serve as a point of reference - because they don't exist.

Ok so it's bad wide open; my 40 Art is going to stay, I guess

Meh. The EF 50mm f/1.2 L was never intended to be a test chart reproduction lens. It was designed to be a portrait lens.

It left some field curvature uncorrected to keep the bokeh smooth. If refocused so that the edges are at their sharpest, it does better than most expect. But that is a different focus distance than when the lens is focused for the center to be at its sharpest.

No, that's not what I'm calling externally focusing lenses. I'm calling externally focusing lenses to those that extend beyond its original dimensions.
There's no need for a stationary element in the front, just look at the RF 50mm f/1.2, for instance. That lens has no protective front element, yet it focuses inside its housing, never extending beyond its length. Canon just needed to add more plastic, enough to cover the movement.

If you know, you know, right?

A guy I used to work for had one that all of the employees of his diesel repair shop (I worked for another of his businesses) used when running errands for the boss. I dropped off/or picked up mechanics in the Peugeot a few times when they would pick up or return vehicles to/from customers.

Anybody coming from a DSLR will not like the battery life of a mirrorless. She's been known, especially in migration season, to head out in the morning with the camera and shoot all day. A battery grip would have gone a long way to helping her enjoy her R7. That and a little more substantial 'heft' for the inevitable times that it gets banged around off trees and branches.

She just ordered a used EF-S 18-135 USM lens, and an adapter, thinking that the heavier lens would give a better feel. I think, really, that that 18-150 lens is such a lightweight thing that it feels incredibly cheap. Like a toy. A rather expensive toy, given what it costs new. That lens might have been what made her feel like it was less of a camera than her 2 Nikon DSLR bodies. Her 7200 died, but way over 200k shots on it, so it served her well for a long time.

As for me, I always carry an extra battery or two when I go out to photograph birds, or just about anything else really. I did the Cleveland air show Labor Day weekend, and swapped out the battery about 3/4 of the way through the show, just before the Thunderbirds showed up, so that I wouldn't have to deal with a dead battery at the wrong time. It still had around 10% on it, but definitely better to have a fresh one in there.

Lack of any possible battery grip is one reason why I would never buy an R7. My right shoulder and its limited range of motion is to the point I can't hold the camera steady enough to shoot portrait orientation without vertical controls.

My definition of a unicorn is a creature or camera that exists only in someone's imagination. As it did really exist, the 7D Mark II was not a unicorn. Your hoped for "mirrorless 7D Mark II" or "APS-C R5" will be unicorns unless and until they're actually put on the market.

I notice from the gear list in your signature that you don't actually have any mirrorless camera at all, just DSLRs.

I suggest that you get some actual experience with a Canon mirrorless camera before you start telling those of us using them that it would be great for Canon to change the next model of the camera we're used to to make it more like some old DSLR you're used to.

If you look at the back panel of the R5 and R6 series cameras, you'll see their joysticks are in essentially the same position as the nested dial and joystick of the R7. Only on your 5D and 7D series DSLRs is the joystick lower down on the back. (And on the oversized R1 and R3 models that have permanent battery grips - so it can be reached when the camera is held in portrait orientation.)

So if you intend to use the joystick on any of the Canon mirrorless bodies that don't have a permanent battery grip you'll be reaching your thumb to the same place as the R7 combo.

I have no objection to Canon putting a third control dial in the traditional location onto an R7/II - just leave the one by the viewfinder alone. You do know that you can set any of the controls on an EOS camera to do whatever you want (or nothing) - right?

When is the last time I've updated the gear signature for my account? I have no idea how long it's been. Not to mention that just because I don't own certain cameras does not mean I have not shot with them. Some more than once. However, I'm not free to publicly post or share most of what I've done with cameras I do not own.

As to your assertion that the Joystick & Quick Control Dial on the R5 and R6 is in the same position as the abomination on the R7: That is categorically untrue. The joystick may be in a similar location, but the dial around it on the R7 means the thumb must curve over the dial to get to the joystick, instead of lying flat on the diagonal area of the rubber (?) material below right of the joystick. The Quick Control Dial is, of course, in a totally different position also much more accessible with one's thumb, and closer to the left edge so that arching the thumb a bit to not press the Set button when undesired is not a problem.

Call it Double-Gauss design BASED, if that makes you feel better.
And about the propper notation:
Start complaining at wikipedia first:

Double-Gauss lens - Wikipedia

en.wikipedia.org

You'll find there:
Double-Gauss
Double Gauss
double Gauss

And you'll find there numerous lens designs all claimed to be Double-Gauss (or Double Gauss, or double Gauss).
So if you'd ask me about consideration, this RF 45 could be closer to a Taylor&Hobson.
And "your" reference of the EF 50mm f/1.8 STM has two elements more than than the "classic Double-Gauss" (or Double Gauss, or double Gauss).
So it's an evolution as well, closer to a "Zeiss Planar" design.

In the end:
If you'd use German it would have been even better and more precise:

Gaußsches Doppelobjektiv

Gaußsches Doppelobjektiv – Wikipedia

de.wikipedia.org

as for the meaning of a symmetrical mirroring of a basic Gauß lens.
(as this German person Carl Friedrich Gauß is correctly spelled with a German "ß", called "Eszett" or "scharfes S", but in the past as well with an "ss", so welcome to maximum confusion).

Enough "know-it-all"?

And in the end th inventor of the Double-Gauss design (or Double Gauss, or double Gauss) was Alvan Clark, acording to wikipedia. Is he a relative of yours?

Since when is Wikipedia an authoritative source for anything? It's crowd sourced. It's not peer reviewed.

I'm sure you guys have already full mouth of this leucistic House sparrow but at 70+ I have no idea when I will see something like it again (if at all - huh, most probably not!). So, I'm going there once of a week and take what I can... On other hand there are not much birds around that I have no photos of (right now may be two but on a places that you shoot to document, not for really good photo...).
BTW: sometimes I really want to grab and clean little bit the bird but you know....

Doing the same things as the other manufacturers is not a very sound business strategy in the long term.

You want to use the lens for astrophotography, so you probably want it to be optically corrected, rather than rely on digital corrections. That means it will be big, heavy and expensive (optimistic guess between 3500 and 4500 USD/ €) and is not likely to sell in huge numbers. I.e. it would not have a significant impact on Canon’s marketshare, revenue and profit. Even if a few customers leave Canon for greener pastures elsewhere.

The list of lenses that Canon MUST make to avoid imminent doom, according to some users of this forum, is a very long list: tilt shift lenses, the (rumored) Sony f2 trinity, a light 300mm f2.8, Nikon’s “affordable” PF telelenses, “real” RF big white 400, 600, 800 and 1200mm lenses, “real” L-lenses instead of the VCM primes, RF big whites with built in converters, a whole list of Sigma and Tamron lenses, and I’ve probably missed a few.

How Canon should make these lenses and remain in business in a market that was shrinking until a few years ago and since then has not been growing very much, is usually lacking in these “Canon must make my dreamlens or they are doomed” posts.

Edit: Leaving aside why these posters think their knowledge of the camera market is better than that of the company that has been the market leader for a long time. A company still doing well after the collapse of the camera market and managing the transition from the EF and EF-M mount to the RF mount.

I keep struggling with why the VCM series is not real L? One commentor has called them blasphemous. I don't understand the hate. Is it the digital correctionns?
