What does the AD-E1 actually do?

I’ve never seen it try both. But I only rarely shoot in very dim light.
I asked my friend and she's never seen the body fire then it switch to the speedlite. She regularly shoots in low light for crime scene photography and she does part time wedding photography with her mom. My friend started out with the R6 and didn't like it. Then moved to the R5 & recently got the R6 II. She ended up giving the original R6 to her mom when the image sensor went out in her original 6D. Her mom has the original R6 and she's seen the camera switch between body lamp and speedlite. She has either donated or sold her old gear mainly lenses. Her mom ended up keeping her old 600EX-RT & 580EX Mark II and got an EL-1. Her daughter ended up with the 550EX. I ended up with her old EF 85mm F/1.8 USM, EF 50mm F/1.8 STM lens and the 470EX-AI speedlite. I already own the 600EX II-RT and that's enough for me. I mainly use on camera bounce flash no wireless off camera slave flashes. This all started as a hobby and still is for me.

Canon EOS R8 will likely be available in late April

Porsche "used to make only a few cars models". There are now twenty three variations of the iconic 911, then there are several variations each of the Macan, Cayenne, Panamera, Cayman, Boxster, and Taycan. Perhaps Audi owners should own Canon cameras. They make the R8, RS3, RS5, RS7 :ROFLMAO:
That way they can use the same model camera when their car is in the shop.

UK pricing for the new Canon gear has leaked ahead of tomorrow’s announcement

3000 lp/mm is, of course, impossible for a dry lens and visible wavelength light.
As @neuroanatomist writes, be careful in saying impossible. Using the standard formula (10^6)/(f/#)×λ) for the cut-off frequency for resolution in lp/mm and the wavelength λ of 520nm usually used in the calculation, an f/0.95 lens has a theoretical diffraction-limited resolution of 2025 lp/mm.
According to Wikipedia, there are the following lenses:
  • GOI CV 20mm f/0.5 Mirror lens (2.9 mm image diameter, 1948; design and glass types used are well documented for anyone wanting to build their own
  • Signal Corps Engineering 33mm f/0.6[12]
  • GOI Iskra-3 72mm f/0.65 Mirror lens
which give theoretical diffraction limited resolutions of 3848, 3206 and 2960 lp/mm respectively. Zeiss made as a macho joke an f/0.33 40mm lens, which could have given a resolution of 5800 lp/mm. If the Military needs a 3000 lp/mm resolution lens, they will make one. I wonder what was carried by the shot down Chinese "weather balloon"? A 3000 lp/mm resolution lens may have been there...

A Canon CP+ 2023 interview...

...

I remain flabbergasted that Canon has 'relegated' the M format to the dustbin. It does not make sense to me.

And their M-related comments in the posted link above don't really make any sense either, when combined with the lack of activity as far as new (M) products are concerned.

...
Why are new models - cameras or lenses - necessary to avoid the conclusion Canon has relegated the M system to the dustbin?

It seems to me the M system was designed from the beginning with small size and low weight as a key requirment. Canon has never released a range of "premium" fast lenses for the system to compete with the options available for other APS-C systems (particularly Fuji's). I can therefore imagine the M system being purchased by people who want a decent little camera but are not seriously into photography in the way many CR members are, so I can see that group not being quick to upgrade equipment if their existing equipment is still working fine. I can also imagine the M system being purchased by people who are seriously into photography and have the large, heavy, gear, but want a small second system for occasions when small size and low weight have to take priority. Since the M gear is a secondary system for those people, again I do not know how quick that group would be to upgrade (or to buy larger, heavier "premium" M lenses - they would have their primary system for those sorts of lenses). I do not know if those two groups are the primary buyers for the M system or if I am correct about the buying habits of those groups (and of course there would always be some people who would have different buying habits), but I can imagine it might be the case, and if it is the case then I can imagine Canon not seeing a need to update M models wtih the same frequency that models in their RF system (and previously EF system). If the M system already does it what it needs to do for the target market, releasing new models may not have much impact on Canon's sales/profit, so it would make sense for Canon to use its resources to design gear for other things such as the RF system.

All speculation on my part, but I just don't think Canon's failure to release new M gear for a while necessarily has to mean Canon has abandoned the M system.

On the other hand, if Canon has abandoned the M system, my guess is it will be because Canon sees the M system as being another victim of the camera phone as camera phones continue to improve. If camera phones are good enough that an APS-C system the size of the M gear doesn't offer enough advantages to entice buyers, that's it for the M system. And for example, I see Neuro saying in a post above that he is thinking he might take his camera phone and an R8 on an upcoming trip and leave his M gear at home. That's only one person, of course, but maybe we are seeing the M system falling victim to the phone camera. If that's the case, Canon might as well leave the existing M gear on the market for a bit longer if it still making some sales, but obviously Canon wouldn't be devoting resources to new M product.

Lens design comparison: Canon EF 50mm f/1.8 STM and the Canon RF 50mm f/1.8 STM

My main takeaway is that you have a really good eye and a beautiful yard :-D And are very good natured to go make such an excellent comparison.

The Tamron might be the most pleasant, with the other two giving very slightly the "glass bubble" effect that normally I don't like but you use to good effect here. Tamron has a softer edge even if perhaps with a color tint. But I also think the bubble edges go away at f/2 or so, so the lens designer is actually giving you your choice of looks. By the way the 100 Macro's spherical aberration control can give you your choice of glass bubbles in front, or behind, your subject. I haven't done much with it. RF seems to have the best CA (the wires of the lamp's cage are more nearly the same color in front of and behind focus, while the other two are distinctly green and purple).

I've written elsewhere (maybe in this thread actually!) that makers can make the 50s either in a plain old cheap unsharp compact double-Gauss, or go with a much bigger, sharper, more expensive modern design. Canon's done the former with the 1.8 and latter with the 1.2, which seems like a reasonable mix. I think they should also make a few $10,000 50/0.7's as sort of a halo model.

USD pricing for the Canon EOS R6 Mark II and Canon RF 135mm f/1.8L IS USM has leaked ahead of the imminent announcement

Is it from old 6D2 or Rp?




One the other Sony shills already asked that. You must have been late getting that script.

The 6D Mark II and EOS RP had 26 MP sensors, not 24 MP sensors.

The only 24MP FF sensor Canon has ever put in a camera is the one in the EOS R3.

135mm SHOOTOUT! Detailed Analysis of the Hand-Holdability and General Sharpness of the RF135/1.8, the RF100-500/4.5-7.1, and the EF135/2

I tried a few 2 sec shots with the 50/1.8 across the room.
I should have been clear that I was referring to lens IS systems, which the 50/1.8 lacks. IBIS likely behaves differently.

I haven’t tested this on a R body, I did so some time back with my 1D X and two lenses (100/2.8L and 600/4L II).

Canon releases financials for the full year 2022

I keep being surprised at how many people, under 30, I interact with have photography as a hobby. At least 3 people working at the local bakery, which shows in the product shots on social media, 2 of the teachers in the day care, a nurse in the ER, the resident cardiologist. The catering lady in the hospital was over 30 and into Tik-Tok :)

The above is a combination of anecdotes and confirmation bias and doesn't have a bearing on the ILC market :) People listing photography as a hobby can and do get excellent results with their phone cameras.

I wasn't aware that the Netherlands is part of the U.S.

Due to my work in scholastic settings I encounter a large number of students. 15 years ago more of them were interested in still photos, both in terms of creating them and consuming them. Now almost none of them are. Their parents, especially the older ones, are still somewhat interested in still images of their children engaged in school activities but even they are fewer in number than was the case about 15 years ago when smart phones first exploded into common usage following the introduction of the first iPhone in 2007.

Yes, one can do some pretty nice photography with smart phones. But the ability to create and view decent quality video using the same devices seems to have vastly superseded interest in still images as the bandwidth available to phones has increased.

Black viewfinder on R5

You have to give some more information.
When does it happen? Always? or when you turn on your camera? Is it only solved by setting the mechanical shutter? Or also by turning the camera off and then on again?
Everything you do or how it happens helps solve your problem.

I only use the mechanical shutter. Only when I make video's the electronic shutter used.

RF Lenses or EF/RF Drop-In Filter Adapter ?

There isn’t and won’t be. Lenses are designed for a specific flange focal distance (mount to sensor). That distance is 44 mm for EF and 20 mm for RF. The difference is why the adapter is needed. The product you’re suggesting would add extra space between lens and camera. Those products do exist (without a drop in filter) – they’re called extension tubes. Canon made them for EF, 3rd parties make RF versions. When used, they increase maximum magnification by allowing closer focus, at the cost of losing the ability to focus the lens on distant subjects.

Just as an example, putting something the length of the EF-RF adapter behind the RF 70-200mm lens, you'd have the convenience of being able to drop in a CPL or ND, but you could not focus the lens on anything further away than 2 m from the camera. Would you want a product like that?

There are products designed allow filters behind the lens by fitting a bit into the camera body (for both EF and RF), usually used by astrophotography folks. But those do not allow use of a CPL that needs to be rotated.

If you switch to RF lenses, you're back to moving a front CPL from one lens to another, although if you pretty much always use a CPL, an alternative would be to have one for every lens.

I do understand your dilemma. I have both the plain EF-RF adapter and the DI version (with both CPL and vND filters, and the clear filter when I don’t want to lose light). For my EF 11-24/4 and TS-E 17, the front filter options are very inconvenient (dinner plate size filters for the former that I don’t have, salad plate sized filters for the latter that I do have and are a PITA to carry and use). There is rumor of an RF 10-24/4, but I don’t think I would give up the convenience of the drop in filter for an extra millimeter on the wide end. Similarly, there is rumor of an RF TS 14mm – that would be a tougher decision and honestly I’d probably buy such a lens but keep the TS-E 17.

For many of my EF lenses where there’s an RF option I switched, e.g., EF 16-35/4 to RF 14-35/4, EF 24-70/2.8 to RF 28-70/2 (I had the RF 24-105/4 from when I bought the R to try out the system, but I didn't fully commit to RF until the R3 came out), EF 70-200/2.8 II to RF 70-200/2.8. The improvements were worth it to me – the extra 2mm on the UWA wide end keeping the same 77mm filters, an f/2 standard zoom, the more compact 70-200 with better IQ. For other lenses, I did not switch. The RF 100/2.8 Macro goes to 1.4x mag but has focus shift, so I kept the EF 100/2.8 (if I want higher mag, I have the MP-E 65 1-5x for which there's no RF equivalent and likely won't be for a long time, if ever). I kept the EF 600/4 II, because the RF 600/4 is essentially the EF 600/4 III with a permanent adapter, and the II to III update for EF made the lens lighter but not optically better (I can handhold the EF 600/4 II already). I kept the EF 85/1.4L because I just don't use it enough to justify swapping it for the RF even for the extra half-stop(I previously had the EF 85/1.2L II, so I know what I'm missing and f/1.4 is fine for my uses).

At the end of the day, it's a decision you have to make for yourself. I've been very happy with the RF lenses I have.
Thank you very much for your very detailed answer.
I have for sure less technical knowledge than you. Your comment helped me a lot understanding those specificities between EF & RF, and why such a product is in fact not possible (or too much of a headache to justify using extension tubes haha!).

I guess I'll progressively change to RF lenses for the reasons I mentioned (and that you've confirmed) earlier.

Thanks again!
