EOS Bodies / Re: A Canon 44.7MP DSLR at the End of August? [CR1]

I usually don't dabble in reading about DR test charts and viewing blownup 35mm 40x60"s with a loupe. Sorry if I don't fit into that version of "Informed". I didn't mean offend you with my comment, It wasn't directed at you. :P

I'm sorry myself, my post was more aggressive than intended :-\ ... all I wanted to say that "you don't need more than [insert mp number here] resolution" or "you don't need more than [insert dr value here]" are very subjective and there are good and valid applications for more dr and more resolution (macro / cropping from the same source / aspect ratio change!).

The "return of invest" of higher specs is falling, 12->18 mp was more important than 16->24 mp, same with dr, but imho we're not at the stage where people wishing for better specs don't make sense can be called out of their minds right away...

Are there any example pictures from 70d vs 60d on full size?

For the answer/links look just two post above :-\

I lol at DRones who forget that 21MP still makes Jumbo sized prints.

What high res is good for has been gone into in quite detail, it's not only for large print sizes - feel free to read up on that, denying every use for more than 20mp doesn't qualify as "informed" in my book.

As for DRooling DRotographers who want DResperately want more DR: blown highlights are blown highlights at (nearly) at every print or screen size, so I hope Canon won't sacrifice advancements in one area for the other.

44.7MP sounds too great to be true!

Plus it's more than Nikon's 36, so all those people whining about resolution can stop buying a d800 and start saving for a 1d ... now we only need to see the dynamic range :-p,  I wonder if Canon's new baby will have raw recording like non-1d bodies with Magic Lantern.

IS on a 50mm? Why?

Because their fast zoom in this range doesn't have IS, so rather than go f2.8+IS they do it the other way around: 1.8+IS :-\ ... and they'll probably also design and market these as video lenses.

That's cool I see your point ... but a cheap fifty without IS already exists.

But w/o a decent af system...

Not sure if it has been posted before, but here is a link to a polish site with test shots ranging from ISO 100-25600.

They shot this with the 50L @f8 and it's still soft which makes me believe these jpeg shots might have (some) noise reduction applied?

Anyway, the 60d vs 70d comparison doesn't get my hopes up for a significant performance, the 70d looks about the same as the 60d plus a minor boost in resolution:

* iso800: http://pliki.optyczne.pl/C60D/IMG_3442.JPG vs. http://pliki.optyczne.pl/C70D/przyk1/C70D_f14.JPG
* iso6400: http://pliki.optyczne.pl/C60D/IMG_3464.JPG vs. http://pliki.optyczne.pl/C70D/przyk1/C70D_f17.JPG

As always, this is really not saying anything until a final 70d raw converter is out which usually takes a while because ACR is only released every couple of months.

Here's a start, and a Google search for "canon uniwb" will pull up plenty of reading material.

Thanks! Strictly speaking the Magic Lantern raw histogram/zebras/peaking in the picture review are better, but they also draw a lot of battery power, so I'll have a look at this.

There are tricks (neutral or custom picture style and custom/shifted WB) that you can use to get the histogram and highlight clip warning 'blinkies' to more closely approximate what you can pull from the RAW file.

Interesting, never heard of this - any details available on how to achieve it exactly? I shoot raw anyway and it would be handy for flipping through the shots and look for real overexposure.

How come nobody else is hacking cameras?  Why is it always magic lantern?
Why duplicate what someone else has already done? Join in and work on something that interests you or make an existing feature work better.
Or could it be that no one else wants to open themselves up to liability?

Canon has (inofficially) conveyed that they have no problem with ml as long as they leave the 1d series alone.

Btw there are other projects adding custom fw to the cameras like 400plus, but for the newer models they joined up for ml. The reason is that the main work is not the actual coding, but the reverse engineering of Canon's digic and DryOS software, both undocumented (thanks, Canon).

It doesn't make sense duplicating all this, and the ml software framework is very mature and easy to use to add something to it - I often do if I want my camera to do some convenient things like auto-switching to fast drive on bracketing or try to stick to max. x-sync w/o risk of severe overexposure like the Canon fw does.

I am not sure I understand the advantage of displaying on the LCD, a RAW file unprocessed.  What would you see?

You would see the real clipping, the blinking areas on the current cameras are only for jpeg and don't show how much highlights can be recovered from raw. Magic Lantern's raw zebras/histogram & auto-ettr is very helpful here, but even with that you cannot see the clipping *after* shooing because ml isn't able to re-read the raw from the card.

Japanese companies are blame/credit centric. Before the start of any project, a chain of blame (in the case of project failure) and credit (in case all works out well) has to be established. This is very time consuming.

Thanks a lot, I'll store this information in my permanent memory, it's always great to have people with professional experience disclose these things!

Can you show us an example of when you needed the extra 2 or 3 stops? No really, I want to see. I have no clue what it looks like.

Constantly promoting specific Nikon products in a Canon forum might not be necessary, but I don't get the recent witchhunt for people wishing for more dynamic range ... of course it's useful in high contrast situations, even though even 2-3 stops more isn't enough to pull back all clipped highlights, but it sure would help.

Attached is some shot I recently wished for more dynamic range as it was a noon shot with clipped whites.

I thought shadows were meant to be black, doesn't it look fake if they're not?

If you really don't know the problem you're lucky and seem to be shooting completely different stuff to what I do. There's a difference between clipped shadows because of limited dr and deep shadows where *you* want them in postprocessing - or you should be happy with a mobile phone and half the dr of a current dslr because then images are  destined to look natural, aren't they? No, of course not, +100 contrast is as unnatural as raising shadows until there is the distinct fake "hdr" look.

There are no fab facilities that could produce this sensor (assuming a FF, not a super-FF). It takes at least 2 years, in the case of Japanese mfgs 3 years to get one into operation.

That sounds like educated information - could you please elaborate further why it takes so long from scratch to product? And why do Japanese take longer, extended holidays :-p ?

EOS Bodies - For Stills / Re: 70D features vs 60D
« on: July 23, 2013, 10:59:02 AM »
thanks for the feed back. I am a 60D guy at present.  was just wanting to get a feel of the others out there.

I've got a 60d, and my feeling is that adopting every new generation asap is not a good idea except if you need specific features (video af, wifi, touchscreen, afma). We don't know about the sensor yet, but everything else is very nice and all, but imho not worth the $$$ selling 60d / buying 70d at least for the starting price. And if you want tracking af, you'd better wait for the 7d2 anyway. Plus it takes 1/2-1 year for Magic Lantern to make it to newer cameras.

Can moderator please get rid of the crap about Canon vs D800..

Please don't, I'm very grateful the mods in this forum don't "clean up" threads according to their perception of the topic, elsewhere I find this is ultra-annoying. Even with the good ok' Karma gone, CR posters seem to be able to steer a thread in meaningful bounds, or abandon it if it degrades to silliness after a long time which is also ok.
