What do optics or light have to do with Electronic View Finders (EVF) ???

Everything.

A very major limit on how EVFs perform is how much time the camera's sensor has to capture the light that is needed to generate the image for the EVF.  If you are light-limited (and, we're light limited a heck of a lot), the EVF has to wait for the sensor to integrate the light for the necessary time, and that integration is the limiting factor on both the quality and speed of the EVF.

Quote
Moore's law says, the number of transistors on integrated circuits doubles approximately every two years. Often misquoted as every 18 months  :) I've often seen the 18 month claim in many consumer computer magazines.

Actually, that's closer than usual, but that isn't correct either.  Moore's law is about economics.  (Emphasis added):

"The complexity for minimum component costs has increased at a rate of roughly a factor of two per year... Certainly over the short term this rate can be expected to continue, if not to increase. Over the longer term, the rate of increase is a bit more uncertain, although there is no reason to believe it will not remain nearly constant for at least 10 years."  -- Gordon Moore 1965

He changed the "per year" part to every two years in 1975 when the time horizon of his original prediction ended.

 ... Still no match for a half-way decent OVF or else so many of the RED owners wouldn't have demanded an OVF (http://www.reduser.net/forum/showthread.php?34814-More-news&p=474710&viewfull=1#post474710), which as far as I know, they still have yet to deliver.

Traditionally through the lens viewing, for motion picture cameras, has benn provided by a spinning mirror, it's what many motion picture camera operators are used to and like. The spinning mirroe is both the shutter, and also uses the mirror to reflect light to the ground glass of the optical view finder. Sorta like the flaping mirror of a DSLR. Because of operator preference the Arri D20 and D21 used this style of view finder. The present Arri Alexa range is made-up of 5 models, four with EVFs and the Alexa Studio with an optical view finder.

Operators with a broadcast back ground seem to have no problem with EVFs.

Errr... movie operators shoot video, not still photographs. Still photography captures a moment in time whose duration is as long as the shutter speed of the camera.

I think what he is saying is that since people from broadcast background are used to looking at EVF's, they make the transition easier. I think that is what he is saying.

A studio camera does not need an integrated grip.

A vertical grip isn't needed in the studio because portraits are never shot with camera held vertically.  The term 'portrait orientation' (vs. landscape orientation) came into common usage for no reason, whatsoever.  Right.

And this week's sarcasm prize goes to.......(drum roll) Neuro!! Congrats Neuro, you win a coconut, what are you going to do with it? What's that? Fit a vertical grip to it? That's insane baby, you need a check-up from the neck up! Unless the original post was meant to be sarcastic in which case you lose the coconut but get membership of the National Sarcasm Society (like they need your help).

Sigh, it's been a quiet day....

<p><strong>What can we expect in early 2013?<br />



</strong>The 40+ mp camera gets another mention and we should expect an announcement in Q1 of 2013. The camera will be physically bigger than the 5D Mark III, but will be smaller than the EOS-1D X. It’s noted that the sensor is currently in EOS-1D X styled bodies.</p>

What does it mean "the sensor is currently in EOS 1DX" ??

It means that the 40+ mp sensor is put in a 1DX body for testing.
However, the expectation is that the body will be different when the high-MP camera becomes an actual product.

P.S. These are all rumors, of course.

It means the prototypes are 1D X-style, as in they put the new sensor in a modified 1D X. Doesn't mean that will be the final form factor they select.

I'm looking forward to these announcements.  I decided a while ago to pass on the 5DIII because I just don't consider it much of an upgrade from an IQ perspective.  I have no need for a 40MP monster especially at the price Canon will inevitably be asking, but I'm very excited to see the 7DII and hopefully the next generation of Canon sensors.  I speculate that Canon knows they're losing right now and they'll want to maintain the dominance that the 7D has in the APS-C segment.  My wishlist:

  • I'm good with the 18MP sensor, but maybe 24 MP if Canon can make it clean
  • 10fps
  • integrated grip
  • 61pt af
  • native ISO 25k
  • finally more base ISO DR even though I'm not one who would take advantage of it in most cases
  • even better weather sealing
essentially a crop body 1DX which I think the 7D should be as the flagship APS-C camera

as for lenses

14-24 is long overdue, new 50 1.4 to fix the finicky af mechanism.  I thought the 35L needed upgrading, but now that I own it, it's stellar as is.  I'm not interested in a mirroless camera unless it's FF ILC with acceptable af performance.  The first company to produce it will get my money.  A 7DII for action and a compact FF mirrorless for everything else would be my perfect combo.

I would imagine that's what a potential 70D would be for.  I add a grip to every camera I buy and it's definitely useful for sports and any time you're shooting in portrait orientation.  I think it would also enhance weather sealing for me since adding a grip always introduces another point of failure for the seals.

With or without a grip, none of these DSLRs can be considered small, I consider the benefits outweigh the minor drawbacks.

A non-removable grip is a catastrophe for me, as it makes the camera not fit where I want it, and it makes it heavier and bigger than it needs to be for the 99% of the time I don't need a grip.  If you want a grip, buy a grip.  I never have, and I never plan to.  That's the beauty of a removable grip - those that want one can have one, those that don't aren't forced to have one.  This is one reason I'd never buy a 1D body.

The downsides to a removeable grip are that, when installed, there's a fair bit of flex (which results in additional vibration when mounting to a tripod), and the grip-body attachment has no weather sealing (that's at the battery compartment, and we all know electricity and water don't usually play nice).  The integrated grip is one reason I'm very glad I have a 1-series body.

Since I use a hand strap, simply taking the grip on and off is not something to be done frequently or on a whim.

Also, the accessory grips bulge out both in front and in back, whereas the integrated grip bulges in front only, exactly like the 'landscape' grip. That makes the 1-series more comfortable to hold vertically than a gripped non 1-series body, to me.

Thinking about the next 'M' (is the M for mirrorless?); what I would love to see (read: would buy) is a FF body using the sensor/electronics from the 5D3 (I use those high ISO's), a real EF mount, and a simple optical viewfinder.

All for around $1500.  Which is not an unreasonable number if you think about what a 5D3 costs compared to the 5D2, and then subtract off the AF module and viewfinder assembly.

Take that, Leica!

(in fact, if the AF worked decently and it did a similar number of fps, it might replace my 5D3)

The only gripped body I have had are smaller film cameras and a T2i. It was awkward. After moving to a 7D and then a 5D3 I appreciate a larger body with well placed controls. Having actual man hands, I could work with an integrated grip someday. If they offered the 5D series with one I'd have bought it. No, that is not a 1Dx.
