EOS Bodies / Re: Canon's Lineup Restructuring?
« on: January 31, 2015, 01:33:34 AM »
Canon is going to keep being Canon.  While features always move downward when new models come out, that does not mean a model is moving up scale.
Certainly, the rebels will get new features, but they will not change in price, when compared to the introductory price of the model replaced.
The price of new models will be held down by the market and in the USA, the strong dollar is pushing prices of imports down.  Canon is forced to drop prices due to the low cost of gray market cameras.  In Europe, the Euro is not going up in value, so prices will be more stable.

Yep, and really, if this is nothing other than Canon answering Nikon, the models align pretty well

5dr = D810
5dIV = D750
6d = D610
7dII = ?

Kind of amazing to consider the turnaround...I think a year ago most Canon users were probably frustrated...and now, well, they would seem to have among the most versatile of DSLR options

I certainly hope it has a touch screen and wi-fi. It's long past time for these features to be integrated into upper end cameras.
Wi-Fi might be toucher because of how they build in the waterproofing.

Touchscreen is an altogether different problem. The 5D is still a prosumer and pro market camera...who may not want touchscreen to work through menus, etc.

EOS Bodies / Re: Bingo! New Canon 5Ds has 50.6 MP new rumored specs
« on: January 30, 2015, 11:17:07 AM »
Funny how we always rip Canon for not innovating. With what they have released in the last 2 years, they now have:

The highest MP DSLR (5Ds/r)
The widest rectilinear lens (11-24)
The best/most versatile super teles (200-400f/4 w teleconverter built in, 400DO, etc)
Incredibly sharp wide angles (16-35)
Cheap primes with IS (24, 28, 35, etc)
Cheap pancake primes (40, ef-s 24)

It's basically only in the super-fast prime (24, 35, 50, 85) that they have to update to be a leader for the next 10 years.  And the 50 or 85 may just not get updated for a while

Would you sell the 11-16mm for this??
Unless you needed the extra few mm, or have issues with flare that you cant solve with your current 11-16, then no.

The resale value on the original Tokina is not high, and the vII isnt much higher. So, you're gonna be paying $200 after selling to buy this now. And flare is basically the only thing I can think of that I dont like with my current 11-16 (but, a well placed hand takes care of that)

EF Mount Lens/APS-C Format

Does this mean it will mount to a full frame camera but fills an aps-c image not full frame?
The current 11-16's mount on full-frame and fill the sensor at 16mm. Even at 15mm with a little vignetting. So, if they havent drastically changed the optical formula, I imagine this one would work on full-frame from 16-20mm.

But there are also dedicated options for full-frame that are reasonably priced (Samyang 14mm, and Tokina has a 15-30 that they just released as well)

Well, makes me wonder if Canon will keep producing their 10-22 for much longer. Plenty of 3rd party options that are cheaper/faster, and I imagine most would go with their much cheaper 10-18 if they dont need the faster aperture

EOS Bodies / Re: A Sony & Canon Sensor Partnership Mentioned Again [CR1]
« on: January 28, 2015, 06:29:57 PM »
If, IF Sony had a 50mp sensor, why haven't they put it in any of their own cameras yet?

I find it incredibly unlikely that Canon would use an outside firm to design such an important sensor for such an important camera. On a point and shoot? Sure, nobody is really going to care. But people that buy those high end Canon cameras are going to want Canon tech.
Funny, I know quite a few people on the forum who would gladly take Sony sensor tech if it's better. If you're gonna drop a 50mp landscape/studio camera, it better have the dynamic range and color sensitivity to outcompete everyone else. Right now, Canon sensors dont do that.

As to your other point, Canon does have a 50mp sensor and a patent for it. It may be part of what they are sharing with Sony, who in turn is sharing some of their fabrication processes.

Pricewatch Deals / Re: Price Drops on the Canon Cinema EOS C100
« on: January 22, 2015, 08:36:45 PM »
At this price, the old C100 will sit on shelves for a while. I could get a a7s + Shogun for $4500. 4K, FF, ProRes vs. HD, crop, AVCHD.
Yep, especially with the Speedboosters opening up the various BlackMagic cams, and Sony really pushing forward.

EOS Bodies / Re: Global Shutter Coming to Canon DSLRs? [CR1]
« on: January 22, 2015, 02:54:12 PM »
What's the point of having 30fps when you have video shot at 30fps?  Doesn't the 1DC cover this?  Or is this basically what the mirrorless cameras have, just faster? they have very fast frame bursts..  slightly confused?

The mirrorless cameras (like every other EOS with video) use a mechanical shutter for stills and an electronic shutter for video.

The problem with the electronic shutter is that is reads off line by line in a progressive wave accross the sensor.

Whilst it is easy to make the read of each individual read very fast (thereby equivalent to only being 'exposed' for 1/50th, 1/250th, 1/2000th of a second) the speed at which the scan passes over the entire chip is relatively slow.

This means that the moment of the last line being scanned is visibly behind the first and intermediate lines being scanned.

You may also have heard this being called 'jello shutter'. 

If you have a dslr with video mode, do a whip pan left or right.  Vertical lines become diagonal lines as the slow scan rate of the sensor is betrayed.

In a global shutter the entire frame is read in the one instant.  So these diagonal lines disappear.

Now the if it's doing that to diagonal lines, what else is it doing to other details in the image?

So why is it a problem?

Well, increasingly press photographers have to also provide video, and with the advent of 4K video decent frame grabs become viable.  You could fill a magazine cover with an 8MP frame grab from UHD footage.

But not if all the details are wavy and distorted.

So, there are two benefits...  it will make video a lot better, rapid camera movements are now possible  ...it will make video grabs a lot better too.  Something Canon must see a requirement for in certain user segments.

And I think they are right.

And implement Global Shutter on a camera that shoots 4k RAW video and suddenly you have a camera that can take 8-10mp stills, in RAW, at 24-30fps. Your limitation is no longer the shutter, its the buffer.

How this works within the confines of auto-focus is, I'm sure, it's own interest problem. Its a non-issue on most 4k production cams because you are pulling manual focus anyway. But if that comes with auto-focus, thatd be impressive as hell, even at 24fps

EOS Bodies / Re: Canon EOS Rebel 750D Spec List [CR1]
« on: January 21, 2015, 09:55:07 AM »
Splitting the Rebel line would be strange, then Canon would have six APS-C DSLRs for sale: the 1200D, 100D, 750D, 760D, 70D and 7DII. Rather a lot, I think.
Especially when the only difference between the 750D and 760D seems to be the rear dial (and creative modes that are not useful). That'd be mighty odd to open up a new camera line just to add a rear dial...I presume with the intention of making users love it and want a 70D/7D? Wouldnt they just buy a 70D since they'll be the same price (actually, 70D will be cheaper) upon release?

Third Party Manufacturers / Re: Sony closing down?
« on: January 18, 2015, 10:17:38 PM »
Sony won't close down though. Their sensors are in the vast majority of cameras people are using today, so they can spin that off as a profitable business on its own. Especially since their major competitors rely on them. I'd actually argue their failure to produce a consistent lens line is a function of them not trying to overextend their camera division. Instead they let 3rd parties handle that and focus on making cameras people want. And ones that adapt to legacy lenses that are used in the industry (PL, etc)

I still wonder if the "hack attack" was a publicity stunt to get more people to see the movie. It is a second rate movie with second rate actors and never had a chance to be well viewed.... after the hacking stunt, I am sure it was seen by ten times as many people as otherwise....
Absolutely not. You're forgetting how many people go see comedies nowadays just because of who is in them. Nate Silver ran a prediction (based on similar movies, including Pineapple Express with the same cast) and it would have made $100mil. Heck, even if it made half of that, last estimate I saw was that the Interview might gross about $40-50mil now. So, at best Sony broke even on expectations, probably lost money in reality, and crumbled their entire studio in the process. Sounds unlikely to be a publicity stunt...

The fallout might cripple Sony Studios, but, truth is running a studio might not be a profit-generator much into the future anyway

Third Party Manufacturers / Re: Rokinon 12mm F2.8 Fish-Eye
« on: January 18, 2015, 10:05:35 PM »
Have anyone shot astrophotography with this lens?  I am trying to decide between Samyang 14mm f/2.8 and this lens.  :)
compare the two at Lenstip: http://www.lenstip.com/porownaj.php?co=obiektyw&ile=2&add0=1225&add1=920

That said, the 14mm is one of the standard go-to's for astro work. From the comparison I see, I'd prefer the 14mm for having less coma and for not having the fisheye projection

Lenses / Re: New Rebel & EF 11-24 f/4L USM Coming Shortly
« on: January 15, 2015, 04:22:05 PM »
not to mention 11-24 can also serve nicely as a UWA on a cropped camera body as well.
What a waste that would be when there are already great 10-xx and 11-xx options for <$500 on crop.

EOS Bodies - For Video / Re: Canon EOS-1D C Coming Down in Price Again?
« on: January 14, 2015, 09:07:14 PM »
can anyone tell the reason to use this body for photography? I watched the victorias secret fashion show and saw a couple photographers using the 1Dc you can tell by the little red C on the body, kinda stands out with a black body. just wondering why pay the premium to use it for shooting?
Because its a one-size fits all solution for them. The 1D-C is the 1DX, but with video capabilities for 4k as well. So, if you're a fashion photog, odds are you pretty much have to be able to do both photo and video today. 1D-C is uniquely positioned to do both, and of course, have the ability to shoot high frame rates for other pro jobs.

Honestly, if the new price is true, the question is why anyone would purchase the 1DX. For $1000 more you get 4K video, etc.

with the 4k video you can probably use screengrabs from any video it outputs as photos
yeah, but they are jpeg compressed and prone to motion artifacts. Its the RAW cameras where 4k is really interesting

EOS Bodies / Re: Camera ownership on Flickr: 2013-2014
« on: January 13, 2015, 08:13:09 PM »
Will anybody be using flickr in 1 or 2 years from now? 
Yes, for the same reason Myspace still exists and old photo sites like Photobucket, etc exist. People have TB upon TB stored there, it will survive for that reason alone.
