EOS Bodies / Re: Canon EOS Rebel 750D Spec List [CR1]
« on: January 22, 2015, 09:36:10 AM »
If the were to use a 1.5 crop sensor instead of the 1.6, then the could make a variable aspect ratio like some of the micro 4/3 cameras for movies and still with the same angle of view.

I presume EF-S lenses are designed to just cover canon's APS-C frame, so they would likely have to disable the outer perimeter of a larger sensor, such as the ~24MP Toshiba used in the D7100 and D5200.

Yet more Canon fail  :'(

So the rumored cameras wouldn't sell well? I doubt that. Rather I imagine it will be a relative success.

I won't buy one.

Target and Walmart are popular.....that doesn't mean that they sell superior products.
No, they don't sell superior products to some other vendors. However, both are resounding successes.

That being said, which product is this non-existent camera demonstrably inferior to?

People who buy the Rebels don't know anything about cameras

heh

And why a new 24.2 MP sensor for this and not the 7D2?
Is this maybe a new sensor that matches Exmor?
One could hope. Although poor 7D2.

Let's pretend this isn't a rumor forum and take it as fact that the 750D has a 24.2MP sensor. I would assume that it would be substantially different from the 70D/7D2 sensor. I can't see a company like Canon, with its not-exactly-state-of-the-art sensor line, simultaneously developing and producing two sensors which only differ by a 20% delta in pixel count.

Rather, I would assume they serve different purposes. If the rebel has 24.2MP, I assume it does NOT have DPAF, for example.

Purpose matters.

Second, why does one automatically assume that a 24MP sensor is "better" than 20.2MP?

It's not an automatic assumption. A 24MP sensor indicates a new process, or a sourced sensor.

If the former, it is reasonable to hope (if not assume) that there have been improvements other than making pixels smaller.

If the latter, given existing partnership for compact cameras, it's not unreasonable to assume canon would purchase current Sony sensors, which are better on paper at some things than Canon's in-house line.

Lenses / Re: Fast lenses at a crossroads?
« on: January 21, 2015, 11:58:30 AM »
I see no evidence that Canon is abandoning fast lenses. Each design is a trade study. Wide apertures bring speed and shallow DOF, but add complications (particularly with edge sharpness), weight, and cost.

And the latest 16-35mm f4?  Ok, replaces the 17-40mm wonderfully, but what about the v2 16-35 that was barely better than v1?

Exactly! It's a tradeoff. Could they have made the 16-35 2.8 II as good edge-to-edge as the 16-35 4? .... maybe. At what cost? At a thousand or two more a pop, how many fewer would they sell?

The big differentiator between 7DII and this new camera will be (beside the AF) the FPS and the size of the buffer. The current Rebel's buffer is speced at 3 raw frames, the reality it is just 2 raw frames. The 7DII buffer is 31 raw. A big difference.

Just wait for all the complaints if the new camera gets the better Sony sensor.  The 7Dii sensor would then already be out of date with no replacement in sight for 4 years.

If a happy 7Dii owner becomes unhappy because a new camera comes out with a handful of better specifications on a datasheet somewhere, he's a fool.

If he was unhappy with his 7Dii to begin with, he's a fool for not having returned it.

If he is wise, he'll continue shooting the 7Dii to grab a higher percentage of hard-to-achieve images than the new camera even with its extra shadow detail, and continue using it in environments where the new camera would have to be left indoors.

EOS Bodies - For Stills / Re: POLL: Do you need 1/8000s shutter speed?
« on: January 06, 2015, 04:44:29 PM »
I use it occasionally, depending on how bright it is and whether I want to shoot wide open. In general use, I rarely shoot with shutter times shorter than 1/3200.

That is something a bit cool about the D810 type cameras, you get your FF (and at top most quality) and then you can go into a crop mode and get a decent reach...

Crop mode doesn't get you reach, it gets you smaller files.

Well, my laptops currently have 1.75TB expandable to 6TB.  Everything fits right now with about 500GB to spare.

Fair enough, but that 6TB will cost you significantly. I could go to 24TB today for under a thousand dollars (but god help my online backup solution if I have to).

Anyway, this is neither here nor there. Carry on with actual camera speculations :P

If this 52MP camera really is going to be the 5D Mark IV, then it really, really needs better ways to reduce file size in-camera, including cropping (i.e. 1.4x, 1.6x, 2.0x) and way better reduction methods than mraw and sraw, such as the ones used in the new DNG spec.  I'm not really interested in 100,000 100MB raw files.  That's 10TB!

I concur that better lossless compression would be welcome, but why does it matter what they call it? Seems weird.

Has nothing to do with what they call it.

Just making sure. The "if this is going to be the 5D Mark IV" leadin made it sound like you might live with large files in a for example 1DxS, but not a 5D4. 

I like having all my files with me, and I don't like "smart previews" as they are not full resolution and so can't be used to determine focus or motion blur.

I agree, they're not as good as having native data local, but they're great for archived stuff. At the very least, they allow me to see on my laptop (which only has 256GB capacity) my full library as-processed on my desktop (which currently has 12TB capacity using "only" 4TB drives in addition to two SSDs for software and workflow), and know what images look like without the annoying 'not found' error I'd get if I merely broke the link between the catalog and the data (i.e. viewed a standard preview without the native data local).

But hey, to each his own.

I keep four copies - two laptops that are sync'd and two backups on externals.  10TB would cost over $2,000 and be unable to fit in my laptops since the biggest laptop drive you can get is 2TB and my laptops can only hold three drives.

What are you using for workflow? If LR, now that it allows for the native files to be offline, you don't necessarily need to maintain them on your laptops. External drives + smart previews will save you a bundle in the era of 8TB drives for under 300 dollars.

I use mine with EF lenses in studio and landscape environments. If I know that's all I will be shooting, it's great. If I just grab a camera for general purpose my 5D gets the nod, and I don't hesitate to use it for landscapes.

I find the Sony a bit tedious to use, but the resolution with and ability to use it with canon glass makes it a fairly easy buy.

I suggest renting one first. At the Sony rate, they'll likely have a version 2 in the not to distant future.

Third Party Manufacturers / Re: Co-worker dumps $5k on Nikon

Good for her.  Most of us wish we could drop five grand on camera gear before a big trip. 

This. Hell, many of us with we could have a big trip, let alone spend $5,000 on gear FOR said trip.

Dilbert now why would you go posting something like that on a Canon forum. ::) ::) ::)

Because:

hahahahahaha

you guys make me laugh.

EOS Bodies - For Stills / Re: 5D III Playback Card keeps changing
« on: November 29, 2014, 09:33:59 PM »
This is a bug which I reported to Canon shortly after the 5d3 was released. However they only fixed it on the 1dx via a firmware upgrade.

Can you clarify the nature of the 'bug' to which you're referring, that was 'fixed' via firmware for the 1D X?   

My 1D X has the current firmware; card 1 is set for playback, but if I remove card 1 and close the door, it switches to card 2 for playback and stays there even after I reinsert card 1.  So I believe what the OP describes is the expected behavior.

I'd call it an annoyance, not a bug. It also seems like a solution in search of a problem. Pick it once. If the selected card isn't there, then play from the one that is.

Out of curiosity, does the 1Dx write video to both cards when set to write a copy to the secondary slot? The 5d3 only appears to write video to the playback card.
