• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

    ------------------------------------------------------------

Bingo! New Canon 5Ds has 50.6 MP new rumored specs

Wow. Well so much for the OLPF debate... I tried. Everyone seems more interested in fighting over a pop up flash. Unreal. If anyone would care to raise the bar, go back a couple pages and read the post about the 5D3 with the AA removed

It was a worthy effort -- thanks for trying! :P

Let me try something...


Sooooooo... A true professional never needs any more than 11 stops of dynamic range!







Oh wait. Out of the frying pan and...

LOL! That might be closer to the truth than I want to admit. :o

Guess I'll put my popcorn popper away now...

Ok... but how much mitigation would 50MP deliver to aliasing? Obviously as Neuro pointed out it would reduce the visual effects. But how close would the aliasing on a 50MP no-OLPF sensor be to the 22MP 5D3 sensor WITH OLPF? If the size/appearance of aliasing is reduced by, say, 250%, equivalent to the increase in pixel density... the 5DR may have aliasing and moire so small than it becomes insignificant. Maybe not in EVERY scenario, but perhaps in far more than now?

It won't be as bad, but I mean I don't think Canon put AA filters on the 50D,7D,60D,70D,7D2, etc. all just for kicks, they could have charged the same and made more profit by leaving the AA filter out on those.

I'm not sure, but maybe at 100MP FF I might start going for the AA-less?

Ok, I hear ya. But MF cameras like the 645z, Phase One, etc... no AA. Granted a bigger sensor. But 50MP. This is what has me wondering.
Click to expand...

I've heard that AA filters of MF size are really expensive and that they do a combo of trying to get away with it and powerful software AA applied during RAW conversion (but that still doesn't work nearly as well as true HW AA for a number of very different reasons).

I imagine it probably won't look too bad for most images taken with the 5DsR, but I'd bet almost every shot will have tons of aliased bits of false detail, even if it might look more like real detail to the eye in many cases and that some parts of some shots will show some annoyances.

Has anyone removed AA from the 7D2? That should show pretty much what it will look like.

Nikon D7100 is high in pixels and it gets wicked moire in some cases due to no AA

Look here. 5Dsr is going to be no exception.

Gotta admit though, it's one hell of a sharp image! Holy cow! I think it was taken with the Sigma 50 art.

Interesting photo of the silver coat - good example of where lack of AA would not work.

I do think 50MP will reduce that - curious if there are studies of no AA on a subject across a range of resolutions. I am leaning toward "R" as I do a landscape. But I also will use it for motorsports (yeah I know its 5 fps but I can deep crop) and thats where some patterns caused by tight graphics, fence lines, grandstands, could be problematic. Should I get it, it will be fun to shoot Vegas (my town) - places like Aria with a mesh awning should be great tests.

Anyway, interested in seeing the sample shots. Should take forever to download full sizes!!

Nope 50MP won't do anything. The image shown was from a Nikon D7100 which is crop. Similar pixel size as a 54MP FF. 50MP FF will moire without AA filter +sharp lens.

Canon press release saying they are using a Sony sensor? Snowball chance in hell.

Notice how they mention increased dynamic range? Have they used that language lately?

It doesn't matter who made the sensor as long as it in improved tech I guess. :)

Well they only say wide dynamic range, not increased so we'll have to cross our fingers really tight until we find out if there is any improvement. I like the idea of a quieter shutter. Definitely looking like a camera I am going to like.

I hope that they have made some compromises that sacrifice high ISO for excellent dynamic range, but I am no sensor designer so I don't know if that is the case. I don't ever use any ISO above 6,400 so this is perfectly ok (not sure what one would use higher grainy settings for; 6,400 is great for Milky Way shots but certainly not clean). 5 fps is also perfectly fine for studio and landscape, which is of course what these cameras are for.

leaked press realease from canonwatch:

http://www.canonwatch.com/cw5-canon-eos-5ds-eos-5ds-r-ef-11-24mm-f4l-press-release-leaked/

seems like cameras will be getting a canon sensor?

Three things I note

EOS 5DS R also includes:
•Low-pass cancellation filter

It's called a 5DS R and what is a Low-pass 'cancellation filter' I thought the AA was being taken out not cancelled.
Could it be possible therefore to switch AA off and on?

Up to 5fps - so no faster in crop modes

You stack another filter atop the AA 180 degrees outta phase with the first and cancel out the effect. It was probably a lot cheaper to do it this way rather than creating TWO fab processes where by half the sensors get made WITH and the other half WITHOUT. PLUS, the AA filter is also stacked with the IR filter, so to take out the AA is to take out the IR. Finally, you still have to have something there to maintain the same focal distance from lens to sensor.

Ah thank you for the explanation!

rotating AA filter anyone............... joking honest ;D

If Canon is using Sony sensors, how is DXO going to try their best to give them low scores?

It's pretty obvious they have a huge axe to grind with Canon and will lie anything up they can possibly invent to make them look bad. Every review on the planet shows the new STM 55-250 is vastly better than the previous version in all aspects.

Here's what they consider "no improvement" LoL
