Seriously.... why doesn't Canon Hire Alex and his team....  Way back when I was done with a 350d and kit lens, I was not system dependant... I could have gone Nikon or Canon... ML brought me to the Canon camp. How many 5D2 users have stayed with Canon due to ML... it's amazing how ML has helped Canon.

I suspect there may be more to this than immediately meets the eye, however, there is interesting possibility here for Canon to get a lot more mileage out of existing hardware.

There are however marketing issues - if this really works, we would probably see the 5DIII get more DR than a 1Dx.  As for 7D users - if it works, it will be a good motivator for me not to look at a 7DII (not that I would, as having a 5DII and 5DIII mostly negates the need).  For those with 7Ds, this may be the best investment protection yet. - Again, the proof of the pudding .....

EOS Bodies / Re: The Next EOS M Camera(s) [CR1]
« on: July 08, 2013, 09:11:12 PM »
I just posted a few hours ago in the $299 EOS thread that it seemed like a silly purchase; since Canon would likely be replacing it with a dual-pixel AF markII version.

I guess I was spot on with that prediction.

Sounds spot off, to me. Maybe I'm biased because I bought one for $299. But, if this rumor is true (it's CR1, just the new 100-400 has been for what, 4 years?), the next M will be an 18 MP minor update (T5i/SL1 sensor), and the 20 MP dual pixel CMOS will follow that...but when?  And 'aimed at the FF Canon shooter' sounds like a $900-1000 camera, to me.  So, $299 really doesn't sound 'silly' especially when the camera + 22mm pancake only costs $85 more than the 22mm pancake alone.  That way, the next M can be bought with the kit zoom (since the best way to buy a kit lens is in a kit), and even selling the body for $150 you'd come out ahead...  Or you'd have a cheap body for IR conversion - one almost ideally suited for it as any lens can be used.

Just my $0.02 (or $299, as the case may be).

Can't fault that logic.  I like the idea of IR conversion, since fast AF performance is usually not a factor for IR, since the main use of IR is for landscapes.

Hmm, I'm now wondering what B&H will charge to ship an EOS-M Down Under.....

Almost pulled the trigger on this, but I just can't buy the current mirrorless offering after seeing the 70D announcement. That sensor tech seems designed for mirrorless, just can't buy the last gen tech on this one. There's a reason they're selling them off for such a low price.

+1 There always is a reason.

I was talking to one of my friend last night and ask him is he is going get the Mark III.  He said "It forgoes the SLR system that is outdated which allows for a much more compact body. Imagine having the functionality and image quality of a 5D mark III but with the size and weight of a compact point n shoot. "

If he wants the same coverage of focal length and aperture then this is likely physically impossible.

As has been said the other side of the debate is that a lot of people actually like the size of current DSLR's, look at something like the GH3 and its clearly much larger than it needs to be.

I'd add as well that to me there doesn't seem to against potentially going the Fuji route with DSLR's and having a viewfinder that can switch between an OVF and an EVF to potentially get the best of both, I won't be shocked if we see this from Canon in the future given the amount of focus there putting on video.

To clarify this point a bit:
For one, you can't really make lenses any smaller than they are, and in some cases, you also can't bring them any closer to the focal plane (think about any f/1.2 lenses - light is already striking the sensor from such an oblique angle that there are problems with the amount of light which the sensor "sees").
The overall body/lens package needs to be balanced - current "pro" bodies are "about the right size" to use with a lens like a 70-200 f/2.8.
It would also be difficult to pack all the controls you need on a pro body into anything much smaller without compromising ergonomics.

Canon General / Re: EOS 5D Mark III w/24-70 f/4L IS Kit Coming Soon
« on: June 05, 2013, 06:17:27 PM »
Hybrid IS, sharp MTF, small size, and close MFD/Macro mode make this a tempting lens if it gets down to a reasonable price point (for me it would be $850-$900).  Bonus points if it doesn't distort on the wide end.

Seems it would make an awesome club photography lens to mix flash and long exposure ambient, having the IS to be able to hold the background still for a while.

It could be a harbinger of higher resolution sensors in the future - the resolving power of the 24-105 is not up there with the 24-70s or the 70-200s.

That said, it is still an awesome lens, and existing copies may well appreciate in value if it is discontinued.

EOS Bodies / Re: Canon EOS 70D Coming in July? [CR2]
« on: May 22, 2013, 01:00:51 AM »

I was at the American Girl store and a pretty nice looking mom had a 5D mkii/iii (I couldn't tell and I was busier looking at her other features), and I believe a 24-70.  I'm going to guess it was a $5000 set up to take a picture of her kid with next to a silly cardboard cutout... but who knows, maybe she was using her pro gear on a personal errand... but I think she was a rich woman who had more money than talent... though she did have some nice talents...

My wife goes to soccer matches, and to the watch crit racing with a 5DIII and 70-200 f/2.8IS II and 24-70 F/2.8 II.  It just so happens that she also runs a studio ....

Who says all soccer mums don't know one end of a camera from the other!

Well that gives me some comfort that I did not sink my money into the current version, coz on many occasions I thought of getting the EOS-M but just kept putting it off as it wasn't a priority for me ... maybe the newer version(s) might lure me into buying one  :-\

If they fix the AF, bring out a model with a viewfinder and a wired shutter release socket, and also introduce a better sensor, I will be very inclined to look at it.

What is Canon doing?

Nothing. What a joke of a company.

What is Canon doing?  Delivering value to their shareholders by consistently selling more cameras than their competitors.  If that trend continues, the innovations of other manufacturers may become irrelevant.

The market (and I am not referring to the whingers on this site) seems to be happy with what Canon is doing.  I think an important thing, which a lot of us tend to forget, is that most users of DSLRs never test the limits of their cameras sensors.  That has allowed Canon to get a lot of use of the current 18MP sensor.

It looks like Canon is following a totally planned script.  My money would be on the 7DII being the camera that will show Canon's next generation of APS-C sensors.  After it comes out, Canon will probably wait at least 6 months to trickle the sensor down to the 80D.

What is good to try to do is to plan your buying cycles around your vendor's technology lifecycle.  Decide how far you want to be behind the leading edge, and try to avoid buying when a refresh is due.  That means, unless you absolutely have to buy an APS-C camera (and I am lumping the G1X in here too) avoid it until after the 7DII launches.

Lighting / Re: Elinchroms and High Speed Sync
« on: March 26, 2013, 05:14:44 PM »
Hello all,

Since googling seems not to turn up any understandable results I decided to ask if any one here who could shed some light on the issue (pun intended. :))

I have been narrowing my options down to getting either the 500BRXi kit (500/500w) or the Ranger Quadra RX setup. However, they all say they can do flash durations down to 1/6000th of a second (give or take) but flash sync speed is only 1/250th of a second.
Speedlites can do HSS easily, no problem, they emit several pulses as the shutter traverses across the sensor to light the whole thing. Fine and dandy, but apprently the Elinchrom's cannot do this.
I was thinking though, if I set the camera to 1/2000th of a second shutter speed, but the Elinchroms to output flash over 1/1000th of a second, shouldn't that cover the whole sensor and then some?

There are two issues at play here - the latency of your triggering system and the fact that your camera's shutter uses two curtains.  Up to the maximum sync speed, the entire sensor is exposed for the entire duration of the exposure.  Faster than that, the two shutter curtains form a "slit" which "travels" over the sensor - i.e. the entire area of the sensor is not exposed at once.  As a result, only a small area of the sensor will get exposed by a single burst of the flash.  Hence why HSS uses a burst of pulses.

On the other hand, to freeze motion with studio strobes, you mainly need to ensure that the ambient light is sufficiently low not to have an impact on the exposure, then you can leave the sensor exposed for longer, and the "real" exposure only happens when the strobes fire. - That is how most high speed flash photos - think of a bullet going through an apple etc. are taken - the shutter is left open, and the strobe is fired at precisely the right moment (using a trigger which senses the firing of a gun, for instance).

EOS Bodies / Re: EOS 70D, DIGIC 6 & 18mp Sensors
« on: March 21, 2013, 04:58:02 AM »
From DPReview early preview:

"The focusing speed of the updated hybrid phase and contrast-detect design remains unchanged, which unfortunately means that it still lags behind current mirrorless cameras from Sony, Olympus and Panasonic."

Well done Canon for the LACK of progress in this critical department. Wow! I am totally floored.

I have to admit it puzzles me a little.  It doesn't look like the sensor is much of an advance on the 650D.  Assuming the sensor in the 100D and 700D are the same, that begs the question why anyone would upgrade to a 700D.

When looking at the Canon range, I like the EOS M form factor, but I won't be pulling the trigger until there is a significant advance in sensor technology.  For now, I'll suck it up and lug the 7D.

I have the same opinion about using the same sensor.... for me a basic upgrade for a body must be the ISO performance (that I guess will be the same).... Imagine if they would have kept the same sensor between the 5d and the 5d mark III... it would have been a disaster.

BUT, this camera probably is not meant for me, meaning that, as stated by other user, people would care more for sharing in FB than ISO performance.... well, that is call entry level.

Let's see about the sensor in the 70D and the 7D mark II (if they are finally coming).

Canon General / Re: Patent: Large Back Illuminated Sensor
« on: January 21, 2013, 05:56:11 PM »
Getting higher iso sensors at this point in a mature sensor industry requires innovation.  I would expect to see backlit large sensors at some point in the future to get that additional 1/2 stop of sensitivity.

I am wondering if this is starting to give some pointers as to what we will see in Canon's next crop of APS-C sensors.  I have a funny feeling we may see new technology from Canon in APS-C before it hits full frame - this would mainly be a commercial measure to keep to more cost effective (i.e. cheaper technology) for full frame, and then mature the newer tech in the lower end (APS-C).

regarding another poster's comment - I don't see Canon using different sensor technology in APS-C DSLRs and EOS-M - they will probably use the same sensors, with DSLRs using in-sensor phase detection AF during live view.

85L at 7.1. What a waste!!!

I never understood why portrait and extremely shallow dof seem to be synonymous for some - it's certainly nice to have the *option* for subject isolation and extreme background blur esp. if the bg is crappy, but if either the eye *or* the nose is in focus it's not necessarily the most pleasing look to me and probably non-photogs that don't get high when looking at a super-creamy bokeh (if they know the word) :-o

I think you mostly use f/1.2 when you first get the lens - because you can, and then you start to get real realise that in order to shoot portraits with both eyes in focus, you do need to stop the lens down.
The real justification for shooting this lens wide open is when you are just desperate for light, or when you have a subject where you want to isolate one small part, but not for normal portraits.

What the hell is a tax refund:o :o  ;D

If you overpaid in taxes (in the USA), you can typically get the refunded taxes back in a refund.  =)  no guarantees in other countries.

He was being sarcastic.  I thought the same question...the only people the get refunds are the people have "jobs".

.. and if you overpaid taxes, you were giving an interest-free loan to the taxman!  That's why it's better to owe - that way the taxman can give you an interest-free loan for a few months...

Lenses / Re: New EOS-M Lenses Soon [CR2]
« on: January 17, 2013, 05:29:48 PM »
If canon put decent AF on the EOS-M it would be perfect for me.  The point of the mirrorless is that it is so small.  When you add things like OVF and full frame the whole system just gets bigger defeating the whole purpose.  I have a 5D3 and if I want shots in the dark I will bring it with me.  I am perfectly fine composing and shooting using the back LCD, I would like it as small as possible with Canon 1.6x crop IQ.   

The only other would-be-nice change would be to make it look retro like some of the Fuji and Olympus cameras coming out but that is not a deal breaker at all.

I think your on the money except for the retro bit - I couldn't really care whether it looks contemporary or retro.

The APS-C sensor makes it possible to reduce the flange distance.  With full frame, there is not much scope for doing that, without funky micro-lens arrangements, which to my understanding Leica has patented.  Canon already has problems with the oblique angle of incident light from the 85mm f/1.2.  Bringing the rear element any closer to a full frame sensor would be a big technical challenge.  As a result, I believe it will be difficult to make a full frame mirrorless camera which is much smaller than a DSLR.  In addition, once you are using full frame lenses, you need a larger body in order to make for a balanced system which can be held comfortably.
APS-C quality is, to my mind, good enough for a small camera.  There are people out there producing absolutely stunning images with APS-C sensors.
I would like a viewfinder - as it gives a better ability to brace the camera.  I would also like a wired shutter release.  Once those are available, together with a newer APS-C sensor, I may be prepared to buy an EOS-M.
