Canon EF 400mm f/5.6L going away?

I love my 100-400 Mk II, but for raptors in flight I still prefer my 400mm f/5.6. I wish the zoom had a second 10m MFD so it wouldn't lose focus in the sky so often. I tried a 1.4X III on my 5DsR with the 400mm, but CA wasn't good, so I just crop as necessary. I don't know that IS is very useful when an eagle or hawk is on the move around my home. For perched raptors I would prefer IS, or the the zoom, no question. Here is an Alaskan Eagle with the 400mm on a 6D.0173-Eagle-Nest-c1s.jpg

1.3 crop in R5

I think the size of the files would be a lot better. Its starting to look like we may not see a 7d ii but I would be happy with 26mp for stuff that moves. I have got to the point where I don't take out the 7d ii unless things are far away and also moving. If they are far away and not fast I just use one of the crop modes on the 5ds. I also don't have any ef-s lens now. Not sure I want anything more than 50mp either because the files could be too big for even a new computer. I have an i9 10900k and notice some slow down with 50mp some times. The 45mp of the r5 is what I would use for landscape etc.

Canon releases an official statement about the EOS R5 and EOS R6 heat concerns

Of course people buy high resolution systems specifically so that they can enlarge more. But nobody is expecting to make large prints from very high ISOs.

I think we're talking about the same thing but using different semantics.
What I meant was, if you have technical differences between sensors such as noise, you can't equalise them. As in my example, if sensor A is noisier than sensor B, you can't just apply noise reduction to A and tell 'now the sensors are the same'. They're not the same because postprocessing makes comparison meaningless: you can apply the same noise reduction to B and make it better again, or apply even more NR to A and make it even 'better' than B.

The same applies to downsampling (no matter from high ISO or low ISO images). Trading off resolution for NR doesn't actually make sensors 'equal'.

But in the narrow practical sense, when you need files/prints of the same size - absolutely. Yes, within some limits and by using digital manipulation, you can produce images of the same resolution and IQ from different sensors.
But equalisation will always come at a cost of information loss (from one sensor or both). If you consider information loss, it's evident that digital manipulation can't really make one poor sensor on par with a better sensor.

Here are the specifications for the Canon RF 100-500mm f/4.5-7.1L IS USM

The more I think of it, the more I like this lens vs the DO's (if I had to choose between them).

This by itself gets you to 'close' to the 600mm DO at a much better fstop.
This with a 1.4 TC gets you past the 600mm DO and 'close' to the 800mm DO at a better fstop.
This with the 2.0 TC gets you past the 800mm at a slightly worse fstop but it would cover the range of the DO's (w/o TC of course) w/ less bag room.
This plus an R5 with just running in crop mode for 160-800 w/o the fstop penalty... but at a resolution just under the R (but over a R6).

I could see carrying the 100-500 for the versatility paired with a 2x TC for the optional 600-1000mm reach... and foregoing the DO's... and if running crop could get you up to 1600.

Guess it all depends on the TC IQ.

5 unreleased RF lenses show up again for certification

Wow.

$2,699.00
Thanks for reminding me!
Apparently my guess wasn't that far off ($1), after all.
Now, what do I win? :ROFLMAO:

I do remember so many thinking it would be more like half that!

What will you do with your EOS R6?

There are many things I like about the R6, but, I'm concerned that just like my R, I'd keep touching the lcd screen with my thumb while holding it, and moving the AF point. I've messed up a lot of images that way. The R5 has a space for my thumb well away from the lcd.
I reverse the screen and fold it into the body to protect it. I cracked my 5DsR screen first time in the field.
I have set the middle button on the 4 way controller to centre the AF point. This makes it much quicker to recover the AF point if accidentally shifted. COmbined with excellent face/eye tracking I don't use the drag AF point function anymore.

EF to RF adaptor - third party Chinese versions ...any good ?

...which is why, when the NON control ring adapter is in a kit (and the price is basically such that it is free with the camera and lens), I'd love to have the option to pay another hundred bucks and upgrade, but no, I must pay full boat for it. Or, likewise pay 200 or 300 to get the drop-in filter adapters.
That would be so nice indeed. :|

RF 24-105mm F4 L IS USM Build Quality?

I had three copies of the RF 24-105 I tested them on a tripod and one copy had better corner resolution with less play at the barrel then others.
What was most interesting is that one lens (not the best one) was ever so slightly wider than the rest (at all focal markings).

I think my best copy was very good an all fronts, it's an L lens but also a kit lens produced in big numbers, so I don't expect quality control at the level of the RF 28-70.

R5 NOT replacing 5DmIV?

highly likely will be the case, but I for one is always preferring the OVF for non fatigue usage and that during vacation I don't need to even charge my 2 batteries in the grip more than once, with my vacation usage likely with a R camera I need to charge batteries every night which is tiring... and in fact back a few years when I went to yellow knife for aurora photography, the -30 degrees C temperature did froze up the top 5D III LCD as well as some sony A7 EVF making it barely work after an hour, I do think OVF have it advantage on that
Well, I don't know what to say about that.
Last winter I went to take some photos at Elbow Falls, in Kananaskis, with a friend.
I had my 5D Mark IV with me and he had his Sony A7R3. We were there for the sunrise and it was a very cold day, about -34C at 7:00AM.

In about half an hour my camera's back screen froze. I could still take photos but I wasn't able to see them. Also, some of the buttons war not working properly.
My friend's Sony was fine, to my surprise!

I never had such problems with my 1DX though, no matter how cold it was. Ever!

Sony reportedly removing features from soon to be released cameras due to electronic parts shortages

That would explain it then. Americans tend to get confused about geography sometimes :)

You said the factory owner was in China and could not freely communicate because "big brother" was watching. Then you went on to say he is near Singapore. Singapore is a city state in Malaysia, nowhere near China. Granted, most people there are of Chinese descent, but they are not part of China.
I missed that, he is near Shanghai, I just typed the wrong city.

EF-S 17-55mm F/2.8 IS II (PURE FANTASY, Unless...)

Funny. Today on CR, two stories published of both an M50 and a 7DMII successor!
It's unclear if the camera mounts will be EF-M or RF, or one each.

There is only ONE lens mount capable of mounting to an APS-C camera in either EF-M or RF camera mounts and fully illuminating an APS-C sensor without the waste of EF lenses - EF-S (with adapter)! Come on guys and girls, you know it. The EF-S 17-55mm f/2.8 USM IS II needs to happen ;)

And I'll sweeten the pot, just to grow continued EF-S lens support... Canon should release a 7DMIII in DSLR. All you sports and wildlife shooters are out there for hours, looking through your viewfinders, waiting for the right moment to spray and pray. So, either you'll be looking at a crappy digital LCD with low resolution and contrast, or a gorgeous LCD that saps battery life without mercy. A 7DMIII DSLR with a high pixel count APS-C sensor just makes sense. And that means an EF-S 17-55mm f/2.8 USM IS II needs to happen!
