EOS-M / Re: Some EOS M Information [CR1]
« on: August 19, 2013, 06:34:11 PM »
Why should people overcome adversities to support imperfect product (only blind fanboys do that)?

Fair enough.  Can you please point us in the direction of that 'perfect product' your statement implies exists?  ::)

How about something that sells spectacularly well, far beyond expectations and makes incredible profits for its manufacturer? There may not be such a thing as a "perfect" product but, according to the marketplace, the original M body was thoroughly imperfect. I also don't see why it is a sign of good character ("overcome adversities") to waste money on that bad a product.

Will there be 200-400mm f2.8 ART for $4000? ::) ::) ::)

That would be too large and heavy. How about a 200-500 f/2.8-4, where the aperture is constant (maximum of 2.8 ) between 200mm and 350mm, then allowed to increase gradually to f/4 as FL increases to 500mm? Even that would be larger than the 200-400s from Nikon and Canon. (I've been suggesting a lens like that to Sigma for about 3 years.)

EOS Bodies / Re: An Update on the 75+mp Camera in the Wild
« on: July 25, 2013, 08:49:31 PM »
A few wild guesses:

First, it's mirrorless with an EVF good enough for professionals;

Second, it has 80MP, but they're paired as in the 70D;

Third, when they say "high frame rate", they mean 24 to 30FPS;

Fourth, it's in the 1Dx body 'cause it's a power hog.

109
Sigma should introduce its Big Brother, a 200-500 f/4.

People that bag on this camera at the $299 pricepoint crack me up. What decent camera can you buy for $299 new these days? I own a 60D and a 5Dc and this little guy can spar with them, and go home in a coat pocket.

I'm glad you're amused. I've owned a G10 for several years (plus a 5D3, a 7D and a slew of lenses) so, for me, the real alternative is not in buying a different camera, but rather not buying any camera at all right now and waiting for something that fills my needs better, even if it is more expensive.

I would upgrade for some combination of much better dynamic range, better high ISO image quality, more pixels and higher FPS, in decreasing order of importance. I don't expect these improvements to be compelling enough to upgrade until the 5D5.

The easiest way to think of what a speedbooster does to your sensor size and focal length is the following:

When you don't use a speedbooster, you constantly multiply your focal lengths by 1.6 to get the "equivalent focal length". With a speedbooster that is no longer necessary.

WITH A SPEEDBOOSTER, YOUR APS-C CAMERA JUST BECAME A FULLFRAME CAMERA, AND ISO IS ACTUALLY TWICE AS HIGH AS WHAT THE CAMERA SAYS

So, when I use a 50mm on my NEX-5N with a speedbooster, set at f/1.4 and with ISO 200, I get an image with the same field of view, depth of field, and exposure, as I'd get with that same 50mm on a 5D3, set at f/1.4 and with ISO 400.
There, no more math. It becomes a FF camera, end of story.

You should get an additional 1 1/3 stops of light. If Canon makes it, I imagine they would compensate by making f-stop read accurately... so that the camera would see f/1.8 instead of f/2.8, for example.

Using the booster with the 50 f/1.2 or 85 f/1.2 might prove interesting. The resulting maximum aperture  would be something like f/.75. I suspect that the corners would be a bit ragged.

Why is it that people never seem to get that retailers are not Canon and an individual retailers pricing decision often occurs independent of Canon (or any other manufacturer).

http://en.wikipedia.org/wiki/Post_hoc_ergo_propter_hoc

Fact: Canon is not offering the EOS M for $299.
Fact: There is no rebate currently offered for the EOS-M, which means no enforcement of minimum advertised pricing.
Fact: B&H offered the camera for $299.
Fact: We don't know why B&H made this offer.
Fact: Adorama and Amazon are major competitors with B&H.
Fact: Adorama and Amazon matched B&H's price.
Fact: We don't know why Adorama and Amazon matched B&H's price, but we can speculate it has something to do with the competitive marketplace.
Fact: Eventually, the EOS-M will be replaced.

Assuming any relationship between the last fact and all those preceding, without correcting for all of the other variables, is simply sloppy reasoning.
Have you ever investigated "dealer incentives" that car manufacturers offer to their dealers? The price reduction could have come about because Canon let it be known to its retailers that it had a warehouse full of M kits that it was willing to sell to them (the retailers) at a much lower price and B&H, being B&H, was the first retailer to reduce their price in response. Dealers don't typically sell stuff at a loss without good reason, even if their competitors decide to. Even if the M is being replaced, the retailers could simply hold onto their current kits and reduce their prices to the break-even point when the new model appears. Given Canon's pricing history, that break-even point is likely to be well below the price of the new models' kits.

"Also in development is a focal length reducer for EF lenses, this will be announced with the 20mp EOS M camera"

That is something you hear about more in astronomy.  But a 0.8 focal reducer that would turn your 10-22 3.5-4.5 into, say, a 8-18 2.8 - 3.6 would be interesting.  A Meade or Celestron focal reducer costs in the neighborhood of $100.  Count on the Canon being $300, maybe.  Because it is Canon, and because it has the EOS electronic connections. 

Let's see -- a .8 reducer would make the 85 1.8 a 68 1.4.  But the efl would still be a bit over 100mm because of the crop factor.   This sounds intriguing, but will probably not be inexpensive.

A reducer factor of 0.63 would restore EF lenses to their full frame optical values. (0.63 = 1/1.6).  I wonder if that's it....

The 10-22 is an EF-S lens. It looks like this would only be for EF lenses only. I think you are right on the 0.63 reducer, though. I'm excited for that. The EOS-M just gets more and more appealing.

Agreed -- I got to thinking about it and was about to follow up with a post saying that it likely be EF only because it would need the extra clearance.   I also would like to revise my price guess: this will be marketed as a piece of pro gear -- a Canon teleconverter runs about $450 -- so that would likely be the ballpark for the reducer -- $450 - $500.   I hope it's closer to the first guess, though!

It isn't a matter of clearance, it's how large an image circle the lens throws onto the sensor. With an EF lens, the adapter shrinks the image from 43mm diameter to about 27.6mm. An EF-S lens already has a (nominal) image circle of 27.6mm so shouldn't be reduced more.

So Canon just dumped their current model at a ridiculously low price so that could introduce a very similar model?? The only reason I can see why they would do that is because they figure the current model's reputation is so bad that nobody would buy it at a higher price, so bad, in fact, that they had to incur the cost of a firmware upgrade to make it marketable even at the ridiculously low price.

I wonder if the people who decided to bring the current model to market are still working at Canon?

EOS Bodies / Re: Why can't the 70D be 40MP in regular mode?
« on: July 06, 2013, 09:12:58 AM »
When you're not using live view, will it be possible to take 40MP pics?

WHY?

What do you mean why? Are photographers still stuck on this anti-megapixel circlejerk from 2002?

Huh? Of the Canon 1Dx, 5D3 and 6D, the 1Dx, the most expensive model, has the fewest pixels. Of the Nikon D4, D800 and D600, the D4 has the fewest pixels. Does that mean that Canon and Nikon are "stuck on this anti-megapixel circlejerk"?

« on: July 06, 2013, 09:07:45 AM »
No, I don't think that 40MP images will be possible, mostly because, individually, the pixels are not square. As far as I know, (almost) all current digital cameras use square pixels, presumably because it simplifies image post processing. If anybody knows of exceptions (after the Nikon D1X), I'd love to hear about them

EOS-M / Re: Will version 2 use the new 70D sensor?
« on: July 06, 2013, 08:54:44 AM »
The real question is: What will the M2 be? I can see three plausible directions, all with the 70D sensor: (1) something extremely compact like the current M; (2) something larger with an EVF and a more button-centric user interface; (3) a video camera, with the appropriate user interface. My guess is that (1) is fairly unlikely, considering that Canon just upgraded the firmware to the current body, (3) is something that Canon will get to eventually if not now and (2) is what we can expect.

Then again, somebody is trying awfully hard to get rid of current M bodies.

119
Could this mean they are coming out with a new version of the EOS M?

And maybe within a couple weeks. I'd probably have gone for it if the 70D hadn't been introduced.

Dual Pixel Liveview Autofocus ... If it is there on the EOS-M, we have a winner.  :)

+1.  I can live without the EVF, if they provide one I hope it's a hotshoe accessory to keep the body size small.

The problem with a hot-shoe EVF is that you can't use the EVF and an outboard flash simultaneously and I have a 270EX on my G10 almost all the time.
