"75mp full-frame CMOS Sensor focused on the dynamic range” - an oxymoron? 30mp sensor would be even more focused on dynamic range :cool:
75Mp 14-bit sensor can be more "focused on the dynamic range" than a 30Mp 14-bit one.

:ROFLMAO::ROFLMAO:

Didn't work on me Keith either ! I did a comparison on the two cameras and came to the same conclusion.

If you compare the two RAW files with no sharpening applied to either, then yes the SR has a little more contrast and is sharper. Add a little judiciuos USM and the difference, to all intents and purposes, has gone.

Even at f/4 :censored:

In fact I must dig out my comparison files and have a little competition on CR to see if anyone can guess which is which.
You are equating contrast and sharpening with resolution, but they are different. Edge sharpness can be improved by a variety of procedures, including USM, and, as Aussieshooter implies, that if edge sharpness is what is important to you, as in architecture and little cropping, then an AA-filter won't cause much problem. But, for resolution, details that are lost by blurring cannot be simply restored by sharpening. So, if you need pixel level resolution, which I often do, the AA-filter does lose detail and gets in the way.

nope it's a should-be, not a must-be, in my opinion.
They say IBIS increases sensor heat and therefore noise and therefore decreases the DR.

If there's a tradeoff between IBIS and DR, I'd prefer to have a better DR.
IBIS would be great to have but only if it doesn't affect the DR.

You can always turn off IBIS and make your sensor cooler, if you perceive it makes a difference.

For my part, IBIS is magical when it comes to using specialty glass. My EF 90mm TS L is a treat with it (adapted onto the A7R4). People are rightly sensitive about not wanting to use tilt/shift lenses off a tripod due to the horizon being so important in its various adjustments, but with the heads-up display showing the leveling function and IBIS purring away, I can do crazy stuff like optimizing the focus plane (it does take 2-5 seconds) while taking pictures of my kids running around a field. If I had to set up a tripod for each of these cases, it would never be able to happen.

Similarly, some of the cool new macro lenses coming out of China from Laowa and others can be employed in the same sort of run-and-gun hiking macro trip that I used to like to do with my 100mm L macro, which has fantastic IS. I have a Laowa 15mm f/4 macro shift lens that I like taking on hikes to get super close macro pictures of flowers, etc., while also including the environmental context. Suddenly it's stabilized, allowing for hand holding - at least if I'm not going for maximum aperture depth of field.

Right now the best set-up for me is a bunch of Sony bodies with Canon glass, but I'd love for most of the basic functionality (reasonable frames per second with autofocus being the primary one, and IBIS a couple items down) to finally come to Canon so I can consolidate. My expectation is that this'll be a while, which is why I swapped big whites for Sony superteles for now. Here is the telling thing... If this rumored camera has IBIS, it would be a good candidate to replace my A7R4. If it doesn't, it ain't.

I would buy it with or without ibis

Doesn't the a7Riv drop the bit rate in that burst mode? I'm pretty sure there are some considerable sacrifices to get up to 10fps. I guess it's still useful to get up to that speed when you really need it, but for most applications I'd probably stick with the lower speed and higher bit rate. To each their own though!

I will not start to buy any Canon R or RF lenses unless there is a Canon R body with IBIS and 40+ mp sensor.

I'm definitely interested in an EOS RS, if that's what Canon calls it. I wonder if this will be the camera that brings back a greatly improved version of the long-gone Eye Controlled Focus? I've seen some rumors that Canon may be working on an updated version of that system. The old systems in the A2E and Elan 2E film cameras weren't perfect by any means, but I've always hoped Canon would bring that feature back to market. Current Eye AF systems are getting better all the time, but combining that technology with the ability to track exactly where you're looking within the frame would be even better. This has been an interesting discussion on the pluses and minuses of fully articulated screens. I happen to love them! As a stills shooter with little interest in video, I use the screens on my M50 and 6D Mark II frequently, both in landscape and portrait mode, often for low close-up shots with wide lenses. The fact that the extended screen extends to the left side of the camera (from the user's perspective) doesn't bother me at all. I understand that the screen wouldn't extend fulliy when using an L bracket; I have the same problem when I attach my bracket for portraits. But the screen does come out far enough for me to use it for vertical shots even with the bracket in place.

I understand this point of view but let's pretend for a minute. If the competition didn't have it, would you demand Canon to have it ? In the past year I have seen 90% of the desire for Canon products to be keeping up with the Sony/Joneses...not asking for bodies and lenses for the sake of particular shooters needs.(meaning, they always mention Sony) I couldn't give a rats tuchus what systems which I am not invested in have features others are using. But that's just me I guess, everyone else is in the 'Play catch up Canon/Canon is *******' race. Perhaps it's the Ebay culture of easily parting with and selling your goods (which I find to be a major PITA) for others that fuels the GAS and self deluded needs.

Could it be the understanding that digital imagery is in it's infancy and I'm still clinging to my film based curmudgeonly views where folks did just fine with much much less?

I don't need no stinking IBIS, the glass stabilization is more than fine, especially the new 4+ stops lenses.

If there were no difference at all, it would mean that the AA filter was useless.

There was a statement that there's no difference between 5DS and 5DSr, just need to apply sharpening to 5DS. But sharpening only improves perceived sharpness and doesn't recover anything. I can apply the same amount of sharpening to 5DSr and make even sharper than 5DS again. Sharpening slider doesn't make the original in-camera sharpness better.

Moreover, any digital manipulation (almost any) means information loss. AA filter makes a physical information loss, and sharpening - a loss in postproduction.
Some may think it's not worth the price difference, others may think it is, as it's clearly shown in this thread.

Yes, yes, yes!!! Please Canon, make it come as fast as you can!!! :D :D Now I am happy! I see Canon Stepping forward! Now i can sell my Sony mirrorless and back to Canon 100%! I did love this experience with Sony, but cant wait to be 100% Canon fully user again. I am not by any means "excited" about the huge MP....I would love a 40MP camera....But....Well, let it come! It will be a great partner to my 1dx MkII. Then...just have to wait for the EOS Rx.

Back in old excitment Canon Days, so please Canon dont screw up on this one! PLEASE! :D

Keith's website?
Not familiar with that, but would like to look at it if you could post a link please?

I've been contemplating a T/S lens in the near future to play with....

TIA,

Hi cayenne,

Here is a link to a great article outlining shift use, he has others for tilt including the newest Canon TS-E Macro lenses.


But Keith has an amazing number if very high quality articles on tilt, shift, printing, color management, unusual lenses, specialist software and plugins, the entire site is a goldmine.

Sony is now the sales leader in full frame cameras (mirrorless and DSLR combined). Canon has slipped to 2nd place. Time for Canon to really get it right!

In Japan. By 2%. In a segment that comprises 10% of that ILC market. But good for Sony, and for us – competition benefits consumers.

The M6 II does 32.5 MP 14 FPS with tracking. Assuming the total throughput would remain the same, this puts a 75 MP Canon at 6 FPS. If they can go beyond the performance of their ~ 1k M camera with what will likely cost north of 3k, we can expect very competitive performance I think.
Indeed, but this is Canon, we need to be wary, what their cpable of offering and what they do offer is different. Also it might need dual digic 9.

I say water balloons at 300 metres.... and since neither can throw them that far, it is all for naught.....
Thank you. Topics such as firearms are not welcome here, it is a gateway drug to yammering on about religion and politics.

I think a lot of us would like to see a return of eye controlled AF but i am not sure it will happen. Remember the eos5 film camera had 5af points. Could a aystem be designed that is accurate enough to work with 500 af points? That is the challenge

You can always turn off IBIS and make your sensor cooler, if you perceive it makes a difference.

The issue with IBIS and cooling is three-fold, and only the smallest part of the problem (heat generated by the IBIS actuators) is resolved by simply turning IBIS off.

The two main issues that aren't resolved are related to thermal mass, and thermal path.

Firstly, to optimise IBIS you need to minimise the mass of your sensor assembly, otherwise the IBIS actuators have to be much larger/more powerful to move the sensor as effectively. If you minimise the mass of the sensor, you're also minimising the thermal mass (i.e. the size of the heatsink), so your sensor will (for the same energy consumption) get hotter faster.

Secondly, because IBIS by definition means the sensor has to be able to move in relation to the lens mount, it also means the thermal path between the sensor and the outside of the body is seriously compromised (in the absence of ducted or peltier cooling). With a traditional fixed sensor, you can have a solid high density thermal path allowing heat from the sensor to be conducted to the body, from where it can be shed by radiant heat loss. With IBIS, you have at best a thin flexible connector with much lower thermal conductivity between the sensor and body shell, so it's much harder to move the heat out.

It may not be an issue with your style of shooting, but thermal management is a serious design constraint.
