EOS Bodies - For Stills / Re: Fujifilm like the EOS 7D mark II
« on: March 01, 2015, 03:17:43 PM »
I wouldn't be suprised if Fuji comes with a very fast AF mirrorless camera. They have done a very good job in producing quality cameras and lenses.
I'm hoping they do, they're already acceptably fast for all kinds of non-action work.

another interesting quote from that interview, however:

Q:  If you had to guess, how many years will it be before the DSLR has no technical advantages over mirrorless?

A:  Thinking about the current advantages of DSLRs there’s focusing speed, lens lineup, overall responsiveness… I’d say maybe two or three years time.

They respect the (AF) speed abilities of the 7D2 and they're gunning for it.
Some Fuji (& Olympus too, i think) lenses are using voice-coil type focusing actuators which are capable of moving very quickly and that could be the ticket to some very high performance mirrorless systems as soon as their bodies catch up a bit more.
SLR mfrs seem to be very fond of various types of rotating motor drives for AF, and they certainly work well enough.  But smaller lighter lenses can use different types of drive, like the linear actuators, more readily.  And that will be another benefit to ML systems as they mature.

What a surprise! With the way Canon has been lambasted here I would have though the results would have been quite different. All this DR and other noise seems to be just that....It will be interesting to see how the DR etc crowd explain this away... :)

I'd like to see a similar report on art and studio photography awards and see how the proportions stand then.

As it is, even niche brands are over-represented here, considering CaNikon have close to 90% of the interchangeable lens market.

"Hitler rants about D3x"? In Germany: "This video is not available. Sorry about that." ... btw even selling Hitler's moronic book "Mein Kampf" is still verboten over here, you never know, 60 years of democracy might not have been enough, so don't let's take chances :-p

That's a very good one, you know actual (former?) Canon users made it :->

DISCLAIMER: Canon fanbois, do not watch this video!

That was good for a good laugh, thanks guys. :)

EOS Bodies / Re: New mirror mechanisms - how is this a good thing?
« on: February 15, 2015, 01:24:05 AM »
Ducati's desmo was the best parallel I could think of in the consumer world that some people would be familiar with.
Sure, it's got it's drawbacks and limitations and conventional valve trains can be pushed to very high speeds.

But doing something similar for a camera mirror is a pretty good idea, as long as it doesn't accumulate any wear and start to slop around.
The extra space taken by the extra cam hardware is partly compensated by the removal of a large return spring and damping items.  Cam profiles can be designed to keep acceleration forces within optical stabilizers' best performance frequencies and this should be more consistent over temperature than passive stabilizers.
I think there are more positives to this than negatives and kudos to Canon for giving this a try.  It's likely the last big improvement in mirror-slappin' we'll see before ML & EVF tech overtake more of the market moving into upscale, mainstream products.

Fuji's XT1 has a very good EVF system and their recent firmware update allows, I think, full silent, no vibration electronic shutter to 1/32,000 altho I don't think it's a global type shutter. If we can get global shutter working at this speed on large sensors that'll be another plus for EVIL/MILC systems.
Hmmm.. I'd better install that firmware update and make sure that it works as well as I think.  :D

cam-driven reciprocating masses can be driven a little more efficiently (quicker, less power needed) and with more acceleration control than a system that's driving against a spring-return.
That means less vibration to wreck image sharpness and a mirror acceleration pulse that is probably more compatible with the OIS system than the smack-whack and vibrate conventional mirror drive systems used until now.
If they do it well, it's a good thing.

For a good comparison, check out Ducati's desmodromic valve train versus conventional cam-return-spring engine design.
You can really push those desmo's!

We've got to get rid of these Bayer filters.  They reduce sensor efficiency and colour accuracy and make moire more prominent.  They've got to go.  There's big gains to be made from alternate colour sensing technologies.

I'd like to see Canon taking the multi-layer sensor concept, a la Sigma Quattro, and implement it really well in their existing system.  Bring noise / sensitivity on a par with existing bodies, but surround the sensor in all the EOS lens, AF, ergonomic and RAW goodness.  Canon could turn this sort of technology into a stunning mainstream camera, rather than the Sigma cult classic it currently is.

Cameras will all end up mirrorless.  It is the natural architecture of a digital camera, with so much to be gained from metering, focussing and composing directly on the sensor plane.  However, there are still major viewfinder and AF performance issues to be solved, so the DSLR architecture will continue to rule for a while yet.  If and when the Canon flagship cameras turn mirrorless, there will be a strong incentive to preserve the EOS EF interface so the implementation might be as simple as making "live view" the exclusive mode of operation with an extremely fast EVF of imperceptible lag, on-sensor AF and electronic shutter.  If the mirrorless architecture truly is superior, it will inevitably follow that the performance of high-end mirrorless, on-sensor architectures will truly surpass that of the best DSLRs.  This is a little way off yet... but not far.  If and when the technology is mature, mirrorless will become the norm for the most demanding photography, including medium format.

We might see pixel-level control of sensitivity, allowing on-sensor implementation of various ND filters at time of capture.

I'd like to see Canon Apple-fy its software, maintaining a firm grip on the integrity of EOS firmware but opening the system to software add-ons / apps.  There's a lot to be learned from Magic Lantern functionality and Sony's approach to apps.  The corporate giant just can't harvest the same imaginative innovation that a bunch of tiny software development houses can bring at their own risk.  It's not just a gimmick for consumer photography, but has the capacity to integrate all sorts of functionality and information into the camera to make for better photos.  It might break system ergonomics, though.  Making WiFi standard would allow flagship cameras, like camera-phones, to join the ubiquitous networked world.

So my bet is that within 10 years the Canon EOS 1-series camera will be a very different sensor technology, mirrorless, and heavily software-defined.

+1
mirrorless is likely to have the next increment large enough to be considered a breakthru and that'll likely be in further improved AF tracking performance and, maybe, improved battery life.

I'd like to see a bit more competitive pressure in the crop MF or, dreaming, real MF sensors too, made suddenly affordable by a new sensor mfg process that delivers high sensitivity, hi DR and excellent color fidelity using a low cost, non-silicon based substrate.  Maybe some kind of plastic with thin layers of photo-sensitive chemical layers applied to it.  ;)  but NOT film!
Seriously, you read it here first.  electronically-sensed, photo-chemical sensels that are responsive to very narrow bands of light from near IR to near UV which can provide a hi-fidelity color response and organized in such a way (like the Foveon) that aliasing/moire doesn't occur.  You expose them like film, read them like a resistance, reset them with a voltage pulse for the next shot.
Somebody get on that and sign me as co-patent holder.

EOS Bodies / Re: DR from 5Ds will be 2 stop better then 7D mk II
« on: February 10, 2015, 01:06:56 AM »
I see the 5DS as being targeted to existing Canon system users. Not first time buyers of high resolution DSLR.

The 5DS will not outsell the Nikon D810 unless:

I believe you should put more thought into the above.  Canon system users outnumber Nikon system users.  The D810 is a very modest update to the D800, released only ~1 year later, so Nikon users who wanted a high resolution camera bought the D800 and are less likely to buy a D810.  Frankly, I can't see how the 5Ds would not outsell the D810.


I agree and moreover I think we will see a number of Nikon users jump ship AGAIN chasing MP.

Uhmmm.... Maybe some will. I certainly won't.  my pair of d800s give me enough pixels to play with and the quality of every one of the ~72 million of them is better than I can expect from anything branded Canon.
OTOH, that new UWA zoom is pretty interesting, and that alone could convince UWA fans to get a 5ds body to put it on, even if they'll have to struggle with DR or noise issues in some situations.

I wish someone made a camera with a super-sized Exmor and 50 megapixels to boot. Oh wait, Pentax does :)
I don't need the extra 28 megapixels, and I sure as hell don't want to sacrifice 1 stop of ISO performance and 1 FPS, so I'll stick with my 5D3. IMHO, if you really need medium format IQ, you need to get an MF body.

Yes, I've been thinking about 645z myself as I start to push my d800/e bodies in some situations.

Quote
That said, I'm glad Canon shooters waiting for a high-res body now have a viable option. I'm sure the 5Ds will make a lot of people happy.

+1.  Even if it's a FF 7D2 for IQ, it's gonna be pretty darn good!
And I've been spoiled by 2.5+ yrs worth of d800 use.

lots of resolution available, but the OOC jpg is still showing plenty of characteristic Canon noise in blue sky at base ISO. This doesn't feel like an Exmor type sensor unless there's been a sudden jump in per-pixel noise with those smaller photosites.
Any further info on what's in the box yet?

I'll still stay with my ABC cameras for now, 5dsr doesn't appear to do me any favors over an 800e at that price.

Really? Noise in the blue sky? I'm not really seeing it...even when I zoom in it looks good.

I did find, however, what I think is a small piece of sensor dust in the photo if you look just slightly right of the helicopter next to the volcano on the left.

2 helis, 3 planes, I do see a dust circle where you stated.
Much of the blue sky noise present is jpg compression, but there is also some fine structure to the noise, visible in some areas, which may hint at some residual canon-style noise structures in the raw files.
I'll have to see real raw files.
Otherwise this is a decent performance.  I do like the detail and sharpness is reasonable even tho diffraction limited.

FWIW, I wasn't too impressed with the tonal gradation at ISO 400 in the fantasy scene either.

For a high-res body, this is a much bigger priority for me than DR. Canon has closed the resolution gap between 35mm and medium format, but I'm skeptical that any full-frame sensor can close the overall IQ gap between 35mmand MF. I know it's not a fair comparison, but Canon's the one making the comparison in its own press release :)

As for DR, according to this preview, the 5Ds' DR is the same as the 5D3.

http://www.the-digital-picture.com/Reviews/Canon-EOS-5Ds.aspx

Even the exmor types are getting near the physics limits of technology so if Canon's still off-sensor digitizing with the pair of Digic processors then we may still be seeing some read noise issues which, combined with the smaller pixels, will make for somewhat noisier images when pixel-peepin.  Down-sampling/printing at higher ppi will make some of that disappear but, from what little I've seen so far, I'm not gonna hold my breath in anticipation of a breakthru here.  i think we'll be seeing a FF version of the 7D2's abilities.  An improvement for sure, but not a panacea.

edit - typo fix

I hope no-one will be dancing if it is only 12 stops (except maybe Nikon and Sony).
Even if it's improved over the 5d3/2 s as much as the 7d2 was over the 7D, Canon users are gonna be very happy with this machine.  There's lots of good stuff in it that will be every-day-helpful.
I just don't think it will be so much better that it would coax me back from the other brands I use.

Is there any way to tell from these images approximately how many stops of dynamic range the camera can produce?
can't do much with jpg files as there's too many hidden variables but, I suspect, it's still hovering close to 12 stops as DxOmark would measure it.
I'm really looking fwd to seeing it tested so I can do my smug-dance. ;)

Lot of haze in that sky too. Don't be too quick to judge.  :)
HAHA!  That's some pretty chunky haze. There's some room for that to be jpg compression artifacts so I'll reserve my total disdain for the thing until I can sample some raw files.

EOS Bodies / Re: Mirrorless vs. DSLR
« on: February 03, 2015, 03:09:06 PM »
I have both a DSLR and a Mirrorless.  Each has its advantages and disadvantages.  That's about the extent of it.
+1, and I get really tired of hearing that we're all idiots for shooting with DSLRs.  If you notice, they are almost all written by street shooters or others whose needs are fully addressed by mirrorless cameras.  Until mirrorless cameras and their lenses can match the 1D X and L lenses I use for wildlife and sports photography, I wish they would just shut their mouths.  And, just because you can make a camera smaller doesn't mean it needs to be smaller.

I own both and enjoy using both, but they certainly have their own niches.  Someday that won't be the case, but I think that's several years or more away.  Samsung is really pushing the limits of mirrorless right now and I think they're the ones to watch.

ditto, I now use both about equally but for different purposes and I like each of them for the benefits they can provide.
However, as many MILCs as I have, it's the ones with EVFs that get the most use.

Today's EVFs are good enough for most typical shooting.  Complaints about using big lenses are just nitch-pickin,' Keep an SLR around.
