You know how silly you are sounding?  I've shot with the 10d all the way to 7d and 5d's. all the prior cameras had even less DR than the 5d3. I've shot landscape, portraits, weddings, aviation, macro, etc. I know what I want and how to get it and I don't blame my gear. I know how to get what I want with what I have, and that used to not be much. I couldn't care less how much DR a camera has, as long as I can get what I want

goody for you, not everyone can get all the DR they need for all types of shots, if you never shoot that fine but don't pretend that is the case for everyone

I'm really surprised that photo software companies aren't jumping all over GPU acceleration. When you can make things go faster using the hardware everyone already has it seems silly not to.

to make real use of it the task must be highly parallel.
then there is the memory problem. memory access and amount of memory.

and GPU coding is not for every java coder out there.
tools are getting better but it´s still not easy.

lots of image processing is highly parallel though

Maybe by then, Intel will have a superfast processor and SATA express will be out.  Current SSD's are limited by SATA III to about 500mb/sec, and huge image files take a lot of time to process.
At least Canon has options for sraw that you can select when you don't want full blown resolution.  With the D800, you get those huge files every time if you want to use raw.
That way a user would have a choice.

Yeah but sRAW isn't really all that RAW and with Nikon you can use crop mode FULL RAW which is great for wildlife since you maintain reach while not wasting storage on all the outer border areas so I'd actually WAY rather they went to the Nikon way of handling it.

I'd rather it be 39MP for perfect video and keeping 6fps than 47 or 50+ and being less than 5fps and having worse video.

Crop mode on my D800 crops the image away.  That's not useful to lose part of your FF image.  Its a feature added for those using the old DX lenses and turns the D800 into a 16mp crop camera.  I could use a 7D and get a cropped image with more pixels than a cropped D800.
If I had 1500 images to edit from a large MP sensor, I'd certainly try sraw or mraw.  I went looking for the feature after I got my D800 and had a day to edit 500 images, it was not fun to spend that many unplanned hours.

It's VERY useful to crop away part of the FF image if you are reach limited since you get a small file PLUS full on true RAW (sRAW and mRAW are not the same as real RAW files) and without loss of reach as you get with sRAW and mRAW. So you get everything you want without any loss whatsoever and save space.

Well, you are welcome to defend it as a business decision. However, Canon's policy of going out of their way to cripple their lower end products does make them less attractive (and difficult to recommend to someone on a tight budget!)

This is where we disagree.  The SL1 is no more "crippled" by the lack of AFMA than the 5DIII is "crippled" by the lack of creative filters and scene modes.

Canon has a nice 2,500 word article on their web site on AFMA and how to do it.  That's about 5 typewritten pages, single-spaced.  Who has time for that?  Advanced users and pros ... and no one else.

Tell the typical buyer of the SL1 that they can "micro-adjust the autofocus" and they will say, "I don't need that."  Tell the typical buyer of the 5DIII about all of the creative filters and scene modes they're missing on the 5DIII, and they will also say, "I don't need that."

AFMA would be no more of a selling feature on the SL1 than creative filters and scene modes would be on the 5DIII.  Some people here would scream in protest if creative filters and scene modes showed up in their 5DIII.  That would be a case of more features making a product less attractive.

When Leica introduced a "snapshot" mode on their $6K rangefinder, that feature was greeted with ridicule and scorn by their user base.  It was something they would never use.

The lesson for the manufacturer is that you don't include features just because you can, or just because they're cheap.  That approach is as likely to turn away some buyers as it is to attract others.  Instead, you choose a package of features that make sense for the intended user and how they're likely to use the product.  Camera makers don't just compete to offer more features, they also compete to offer more intelligent, more coherent design.

You can add creative filters, with much higher quality, AFTER the fact. You can't refocus all the soft images after the fact from poor AF calibration. One doesn't affect the ability of the body to perform to spec the other one does. So I'd say that one of them is a bigger cripple than the other.

But you can't add the exact same creative filters, or as easily, if you have to process them on your computer.  You need time ... and a computer.  Oh, and you need to find or buy the creative filters somewhere.  More time/money.  So omitting them is an obvious loss for 5DIII users.  Likewise, you can't fix all of the blurry images after the fact because you lacked the proper scene mode.  Again, a huge loss for 5DIII users.  ;) SL1 users can instantly dial in the proper scene mode and get the shot.  So why not include those features in a 5DIII?  Are they just "crippling" the camera for the few users who would find those features valuable and possibly necessary?

As I've said before, the Rebel cameras do perform to their spec.  Your theory that they have poor AF calibration and don't perform to spec is based on a different spec shared by a few people on gear forums.  This is like a Ferrari owner complaining that a Kia doesn't perform to spec, especially at the race track.

Yeah you can find the same only better and who uses a DSLR and doesn't own a computer????
Plus, they are a bonus. MFA is fixing something that is broken, totally different.

Yep, when clients are reacting when they see the photos from my 5d3, we ALL know they say "damn that's too bad you didn't have more DR or a 36 mega pixel camera". But, what one of my top models DID tell me that she hated my camera because it has too much detail and shows all her imperfections. Rebel is a rebel, no more no less. Whatever did we do when we had the 10d, 20d, 30d, 40d, 5d classic... The 60d has no reason it shouldn't have afma, but if the 70d doesn't have it, then panic

Yeah well maybe get out of the studio for once and shoot some giant landscapes that can't be lit with flashes or umbrellas....

You just dont get it [/shakes head]...  The day landscapes pay me the money studio does, then I will look at things differently... then again, when I do go out and about, I know what i'm doing, i know what filters I need and I dont fret DR...

Wow so basically unless it makes money it may as not even well be considered photography right?
And maybe if you did get out and try some other types more often you'd realize that the filters you refer to only work for a very few specific types of scenes/scenarios.

I normally use Sandisk Extreme Pro CF cards in my 5D M3 and then several people told me that they don't fill the buffer using a 1000x CF card.  I tried the Lexar 1000x card and the buffer still fills up.   I seem to get a few more shots before the buffer fills with the Lexar 1000x.

Has anyone tried other cards that are fast enough so that they buffer never fills?

Thanks

You want to avoid RAW+JPG though as the buffer for that can still fill fast. JPGs go without filling up. RAWs go for a long time. RAW+JPG can hit the buffer pretty easily.

While we are on the subject... I have a Sandisk and a Lexar UHS SD card... so class 10, but basically 45 to 60 mbps... and I was shopping for CF cards the other day and I think the fastest I saw was 1000x in my budget range. 

So my question is how much faster is the cf card than the sd card?  Is it the write speeds which makes the difference and not the reported read speeds?

On the 5DM3 or just in general?  On the 5DM3, the CF slot is the racehorse. The SD slot is not UHS-1 enabled, and seems to max out at about 25% of what the CF slot can do (with the fastest CF card = Lexar 1000X)...

I knew the mkiii didn't do uhs... which ticks me off, but it's more fake anger.  So a 4:1 ratio... ouch.  I wish there was resale value to my SD cards... but they don't have much of a draw.

Yeah, I will never understand why Canon did that to the SD slot... They have UHS-1 on a Rebel, for goodness sakes! If you write to both cards, for insurance, the SD will slow you down considerably...

I've read that in this case it actually wasn't Canon crippling something but that their chip supplier for Digic, TI, simply didn't make the basic core for the digic with two full speed interfaces and if it had a fast CF interface then the SD slot had to be slow.

With RAW it eventually fills with any card, although Sandisk 1000x 32GB (I think some of the smaller sizes are slower?) it takes longer and, in real world usage, with this card I all but never buffer out (with other cards I would at times, especially for surfing and a long ride with lots of tricks and so on, although a super long barrel can maybe still hit it, but it's way better than before and for the most part no longer an issue).

2172
Should we expect new full frame bodies any time soon?

We just got the 5D3 and 1DX and 6D  :D so I highly doubt before late 2013 or early 2014 at best. Next one might be some sort of higher MP body hopefully finally with a new process sensor that has better DR.

Anyone else interested in trying to figure out if the T5i really has MJPEG support or if DPReview made an error, or do ya'll just wanna fight and argue over a camera that, if it doesn't suit your needs, you're welcome to not purchase it.

Cause I gotta say, while I wouldn't replace y T2i and T4i for a T5i due to it only being an incremental update, a T5i with 4:2:2 MJPEG would be pretty nice for starting DSLR film makers looking for something 'not too expensive' but with decent features.  Right now I'm rendering green screen footage I filmed in a Crown Victoria Police Interceptor on a T2i and I can tell you, it'd be nice if it had been shot on MJPEG instead of h.264.

Why do you think it would be 4:2:2 even if it used MJPEG?
It seems hard to believe they suddenly bare to give away 4:2:2 in a rebel first.

EOS Bodies / Re: AFMA – Easy or Not

Just want to add something that hasn't been discussed before: it is pointless to do microadjust zoom lenses (unless you have the latest models that actually allow to do that) - the amount of correction you will need for smallest/largest focal lengths will be different.

Not necessarily at all. So far for all of my L zooms and my tamron zooms it's been nearly the same value needed at either end, although for one canon non-L it was problematic with the older MFA system since the ends were very different, but I could at least fix one end on the spot to get by in the meantime.
