I've owned two 7D's, two 5D MK II's and two 5D MK III's. My 7D was mostly useful as a studio camera with good lighting, or outdoors with bright lighting. It suffered at high ISO 800 or over, but could be used at 1600 or even 3200 if you were immune to noise or used a lot of NR.

I always preferred my 5D MK II to the 7D's. Finally, I sold the 7D's and bought a used 1D MK II. What a improvement that made.

The 7D was certainly a good crop body, it had some significant good points in adequate light and suffered in low light.

BTW, you need only look at the resolution scores at Photozone, DXO, or any lens review site to see how much sharper FF images are than images from a crop camera. Even a old 5D classic will out resolve every Canon crop made including the 7D when tested using the same lens. The reason is that FF cameras are not as demanding of a lens as a camera with a small sensor. Just because a crop uses the center portion of a lens does not overcome the FF advantage except for vignetting.

And if you need the fps rate with the extra low light advantage and only have modest budget resources, the 5D3 answers both of those... albeit a little slower fps rate than the 7d, the 6fps are still useful... If it wasn't for budget restraints I'd love a 1Dx!

I'm still trying to sell my 7d, just haven't been able to do it quite yet. Still reaching for it in some of my sports work... the 8fps can still make a difference between getting the money shot or getting the shot right before or after the money shot! :

Hello,

is there anything known of some snnouncements at NAB? Maybe the 70d ?

The best source is to read the CR front page. www.canonrumors.com There were two pre-NAB announcements made yesterday.

However, the 70D would not be a product to introduce at NAB. Canon does announce equipment and products aimed at the Television Broadcast industry at NAB, they usually makes the 1D X look cheap. We're talking $45,000 $45,000 and up lenses, for example.

There is a massive thread on the issue, but I believe the 5D3 focuses much slower with the 600EX-RT flash or the 580 flash attached to it as opposed to no flash unit at all (or something along those lines).

I don't have either flash, so I haven't followed the discussion that closely, but I want to say Canon said they'd hopefully be fixing it soon.

Here's the loooong topic on the issue if you have time to burn

This interview with Shaun Williamson (Eastenders, Extras) and Mark Noyce (On the Ropes) discussing their latest film was shot with a Canon C100.

Some test scenes for the film have also been done with the camera and the results have apparently been really good.

Shutter count from jpg works with Nikon and with Canon does not provide that in a file, even raw, jpg it does not writes that exif input.

Thanks...not a viable replacement for the PW TT5's then at this stage.

nope but the yongnuo 622s might be worth a shot they seem to be pretty decent bang for buck at the moment
I'm not sure if they work on the 1Dx and i dont have them but there are a few threads here praising them

Nothing came of it...and perhaps we judge unfairly folks in some neighborhoods, a few stares and may be a comment or two... but it was the longest walk to the larger road from that pot-holed street. I have had a closer call close to my own house few years back, but that only goes to tell you perhaps neighborhoods don't matter afterall.

I pay more attention now to where I am and how I carry my equipment in less obvious ways.

On holiday in Phoenix we, my missus and I , went driving to and walking around various areas looking for / at various things of interest, including visiting a photography shop. When we went out later with our friends who are locals he said he only visits several of the areas we went if he is armed. During our 2 week stay there were 3 shootings in the areas we visited, ignorance is bliss, as I would now not visit the places I have great pics of.
Great subject, some lucky escapes for both people and their gear!
Thanks for being forthright about your misfortunes, hopefully some of us might also learn from you!

The 5D3 will trash the 40D at any ISO above 400 where the IQ on the 40D starts deteriorating. At anything above 800 ISO the 40D's image starts losing detail whereas the 5D3 will cruise up to 3200 ISO.

Kit · Apr 4, 2013

Dear All,
I would be extremely appreciative if anyone has a solution to this problem:
The Canon 5D Mark III sets its default focus point at the centre, but has many focus points for users to choose from. I've been trying to use some of the off-center points. However, every time I changed the focus point (by moving the red square away from the centre to one of the off-center points), as soon as I press "focus", the red square would shift back to the centre, and centre becomes focused instead of where I want the focus to be! And as soon as I release the focus button, the red square would return to the focus point I chose! I've tried this with 3 different lenses, all producing the same result. The Canon Technical Hotline said that it is most likely an issue with the camera settings, and advice that I reset everything to factory default. However, this would mean deleting all my other settings too. Does anyone have a more simple solution (and may be even an explanation) for the problem?
Many thanks in advance for your advice!!
Best wishes,
Kit

This is good to know, regarding the 17-40. Thank you all.

A friend announced to me yesterday, that he just bought the 16-28 Tokina, for his 7D. I hope to try it on my new 6D. Hopefully I will make the right choice. I have a feeling the right choice is to buy several lenses including a T/S, but I would rather not spend the money.

I wonder...does anyone ever try to correct rectilinear distortion? I guess I should google it. That distortion, is why people don't like shooting really wide angle. It's either that, or barrel distortion of a fish-eye...in some cases neither is preferable...which is where panoramas come in. But who has time to do stitched panoramas while visiting a national park or something? I would just wind up rushing it, and miss out on going to enough locations to take pictures. I'm always rushed...time is never on my side. Sort of like posting on here. I sign in to look around for 15 minutes, and an hour later I'm done.

Again, not a rumor -- just a certainty. 8)

This lens absolutely will happen in the near future (next 12-18 months).

"Near future"... I like that...as for me, in the near future, I am hoping to have Jetson-style flying cars released...and I define near future as few years, but over the course of this thread I plan to specify that to be about 5 to 30 years. Also, with 12-18 months you give yourself a rather wide berth there and one would hope it is tough to miss such a generous timeline.

But the irony might very well be that Canon's obduracy outlasts even your safer, longer, 18 month prediction.

It seems to me that Canon is focusing on opening up and expanding into newer, high end venues that were not even around a decade ago...such as mega-K cine platforms and its cameras and lens needs as an example.

Right now Canon has four 50mm models in its dSLR line up ...and their logic would be, though each has its own group of complainers and champions, there is plenty to choose from. I don't see Canon hurrying it up...in the "near future". However, I do not doubt that the 50mm's will be updated sooner or later (see I am being "high risk" just like you).

But all kidding aside, I will be cheering along with you should your prediction come true and may even consider buying the damn lens.

So, I haven't played with my camera above 25.6k, but I'd assume it's the same situation going above there as well?

Just like the L expansion is a digital pull, the H expansion settings are digital pushes, yes.

And, to follow up on neuro's point, because I know somebody will wonder and / or ask...yes, they're equally useless for knowledgeable photographers shooting RAW in manual mode, but they can be useful for those shooting in an autoexposure mode and especially useful for JPEG shooters.

The utility for JPEG shooters is especially pertinent because the 5DIII has such an awesome onboard RAW processor.

If you shoot JPEG in low light, you'd be a bit silly to not enable the H modes. If you shoot RAW and manually expose, there's no point to them.

In the same vein, the shallow DOF and bokeh "seen" wide open at f/1.2 through the viewfinder doesn't correspond in 85L with the image "captured" on the sensor which will have even shallower DOF than what you saw. Even stopped down to ~f/2.0 and even if you press the DOF button to preview, the DOF/bokeh "seen" doesn't change until you stop down to about ~f/2.0+. That is one full f/stop and then some.

But the final image on the sensor will reflect the actual f/1.2 or f/1.4 you set, generating more shallow DOF and bokeh than what you saw through the finder.

Somethings to keep in mind with such fast primes.

It's called shutter bounce and apparently can be an issue on some 1 ds mark III cameras, sigh.....off to cps repairs

East Wind Photography · Apr 3, 2013

No duh's ;D.... It's a lot to ingest. There are some very good white papers on Canon's DLP site on AF, mostly for 1DX. But since they share the same AF system, almost all of the settings function the same. Only iTR tracking and metering on the selected AF point are different.

AF4 on the menu. Manual page 98 under selectable AF point. The manual says when you manually select all 61 points, all will be used. It's only when you manually select AF points. It also says in a foot note that expansion will also still work regardless of this setting. I assume that the center point will always have to be a cross type point but the expanded points may not be.

Harv said:

East Wind Photography said:

AF accuracy on the 5DIII is slightly better than the 1D IV. AF speed might be on par or a little less but even with BIF shots I didn't notice the difference at all. The benefit of using the 5DIII is that you will also get closed loop AF with Canon's newer lenses such as MK II models. Those lenses now report AF position back to the camera. However, even with the older lenses, the AF accuracy is improved.

For best AF accuracy for action, you also need to set the firmware to use only cross type af points. If you have it set to use ALL of them, it's possible for the AF to be less accurate...It's fine to use ALL of them if you are shooting static subjects.

Most people using the older bodies are accustomed to using the center point only. While that is still a very good option for most, the 5DIII offers a few other AF modes that are an improvement over using just the center point....and with most modest lenses, a large block of the center AF points are all cross type.

Lots of benefits to using the 5DIII for action....but a lot more options to tweak based on what you are shooting. It's a bit overwhelming. I've been using a 5DIII for about 1 year now shooting almost exclusively wildlife and I'm still finding tweaks that are improving the numbers of keepers in certain situations. Steep learning curve but glad I have it.

BTW, got rid of the 1D IV and 7D. Now waiting for the 7DII to come out as my 2nd body.

Harv said:

I apologize if this has been covered in the past but I did a quick search on the subject and could not find what I was looking for.

I'm hoping that someone out there has some real world experience and can answer my question.

How does the 5D MkIII AF compare to the 1D MkIV? I'm particularly interested in the accuracy and AF lock-on speed. My primary use is action photography; motocross and birds in flight.

The lenses I mostly use, in order of time on the camera are:

70-200 f/2.8L IS II
300 f/2.8L IS
400 f/5.6L
135 f/2L

I should mention that I do not intend to replace my 1D MkIV, which I have been using for 3 years. If I acquired a 5D MkIII, it would be a second body to use primarily at the motocross tracks. Most likely, I would carry the 300/2.8 mounted on the 1D MkIV and the 70-200/2.8 or 135/2 mounted on the 5D MkIII.

I am also not concerned with the burst rate as 6 fps would be adequate. I normally keep my 1D MKIV set at 7 fps for motocross and it's been fine.

Any help would be appreciated.

That's great information. Thanks.

I read the paragraph above with particular interest in your comment regarding the setting in the firmware for using only cross type AF points. I have downloaded the manual but have been unable to find any reference to where and how that is done. Do you mean to select a point with expansion or a zone that would only include those?

Are you able to elaborate?

Got it. I think I must have stopped reading at page 96. Duh me. Much appreciated.

I have to come back on my promise to buy Eneloop XX's for flash use: according to this page (Dutch language), the standard Eneloops have a lower internal resistance, which means they can recharge your flash quicker. Having emptied six sets of AA's shooting indoors yesterday, I can safely say that to me, that's an important issue

CF > SD

Click to expand...

C'mon. Stop supporting CF tech. SD is catching up in a more reliable and convenient package and on top of that its less expensive. At the current speeds they both are way passed practical speeds from what current cameras offer. Let CF die...

Click to expand...

My d30 is CF only and I need to support CF until another format like XQD is adopted on canon. SD really sucks on the mk3.

Click to expand...

Haha I see : I just want camera manufacturers to stop CF slots. It'll save them space for other electronics and it'll make our end a lot easier when all cameras have the same standard and computers can easily take SD. ;D

Actually, I only see the SD physical interface as being more reliable than CF. I personally think the CF cards themselves (at least electronics inside) tend to be built in such a way as to be more reliable. An SD card has significantly smaller amount of space for NAND dies and controller, while the CF card has more room for more dies and potentially better controller which can do a better job of cleaning up space that's not being used to keep write speeds high.

Now, I very much can't wait to see XQD being widely adopted. Must faster theoretical throughput via PCIe, plus I think with a simple adapter I can stick it into my laptop's ExpressCard slot and read it at extremely high rates. Plus slightly smaller size than CF.

I hope the people at Magic Lantern get their hands on this and reverse engineer the technology for the 1DX and 5DMK3.

Click to expand...

Last I read, they have no intentions of ever bringing Magic Lantern to the 1DX, and explicitly stated they will never attempt to hack it to become a 1DC.

And I agree completely. It's not really a gentlemen's agreement, being one sided and all; more like a gentlemen's nod. As long as Canon doesn't try and stop them, and they've been WAY more generous in that regard than Nikon would ever consider, the ML team has no intention of pushing too far. Turning a 1DX into a 1DC in firmware would be too far.

They're (ML Devs) even speculating that a few "suspiciously convenient" hooks were left in recent Canon firmwares just for them. Which if it's true, means Canon isn't just turning a blind eye, they're passively assisting. That's huge, and bodes well for the future of ML. And shows that Canon sees the benefit of having them around, much like a robust 3rd party ecosystem benefits them.

Agreed completely. Also, since its been confirmed that the internals of the 1D-C are different than the 1DX, I think the ML crew would have trouble with overheating and have to worry about cameras getting damaged with the hack. It's one thing to be able to up a bit-rate or change frame rates...it's a whole other animal to offer much higher resolution, and in the case of 4k, 4x the resolution

FTb-n · Apr 3, 2013

For the past year, since buying my 7D, I thought it or the future 7DII would have a permanent place in my kit. Now, I'm not so sure.

I'm a two-body shooter. The 7D is now my second body, but I find myself shuffling lenses to shoot mostly with the 5D3, thus defeating the purpose of using two bodies. Need to payoff the 5D3 first, but I'm already considering a second FF down the road and will be weighing the merits (and price) of the 6D vs. another 5D3 for this purpose.

Curious side note. The full resolution JPEGs from the 5D3 volleyball shoot averaged between 5-6 MB. Those from the 7D averaged 8-9 MB. ISO for both cameras were mostly 3200. I'm guessing that extra noise accounts for the added data in the 7D files.

Also, I made a rookie mistake during the first game. In switching from RAW to JPEG, I inaverdently switched to Large compressed. But, even those images are cleaner than the ones from the 7D.

Funny that TrumpetPower mentions the 135 and 645 comparison. Decades ago I went from a Canon FTb-n to a Mamiya 645 1000s. When I first started playing with the 5D3 around the house and comparing it to the 7D, I did think "this is a lot like the Mamiya" -- only a tad lighter.

Justin "You are wrong about how good this lens is" - The 24 1.4 II is in desperate need for an upgrade!! This is not a lens you buy to stop down, this is a lens you buy to be able to use wide open in low lit conditions.

The vignetting I guess is something you to a certain degree must accept. But the level of Chromatic Aberration (purple fringe) this lens produces wide open is absolutely unacceptable.

The worst negative of this lens however is not the CA, but the coma distortion.

I work a lot in night/low light photography, and stars in the edges of this lens get distorted to the level that they look like "bananas". If you shoot wide open in contrasting light sources, eg. night photos of a city, the coma distortion in the edges is so bad that it is ridiculous!

A slight positive is that the 24mm 1.4 from Nikon is not any better. But that still does not mean that this lens from Canon is optically a good lens.

The Samyang 24mm 1.4 which I also own 2 samples of, may not be as sharp in the center as the Canon/Nikon 24, but it is virtually free of CA and coma distortion in the edges, and the Samyang even has more glass/lens elements!! Hence I more often tend to use my Samyang 24 than my Canon 24.

The Canon 24mm 1.4 II, as well as all other of Canons L wide angle primes (14mm 2.8 II/35mm 1.4/50mm 1.4/1.8/1.2) are in desperate need of upgrades! I wish Canon would start to prioritize the wide angle department, and not only focus on tele-lenses.

You're right about the Chroma, it's an issue but not one I've seen drastically reduced in any lens of this focal length. The Sigma 35 may be the best I've seen at equivalent apertures (but that's a different story).

The Canon 24 ƒ/1.4 L II was introduced in 2008, if we can assume a lens nowadays has about a 10-year shelf life I'm not sure you'll see an update from them until 2018.

However, good news is that Sigma is stepping up the competition with their "Art" series - it'd be interesting to see if they tackle 24mm next.

And my bad on the night-time photography, you have more experience in this than I, but I do recall seeing some incredible examples of night-scape photography taken with this lens, which is why I mentioned it.

Thanks!

This might be a bit soon, but.....does anyone have experience using this device/app with Android tablets? I've held off on CamRanger because I'm not willing to get an iPad when my Acer Iconia A500 is working fine (though the Retina display is quite nice). Wireless is very much a plus for me and the primary reason I'm considering the 6D over the 5D3. iUSBportCAMERA could sway my decision. I also use an astro modded 40D and a soon-to-be-modded 60D. I'm a patient person, my camera purchase is a couple months out anyway. CamRanger's website implies that Android support is 'coming soon' but I don't see any progress noted. Sanho has been very upfront about the lawsuit re: CameraMator and seems to be very proactive in responding to the market.

Click to expand...

At the moment no Android support ... but if you have Acer Iconia A500, you can use the $6.24 android app called "Remote Your Cam USB Pro BETA" ... I was using this on my Acer Iconia A510 for almost a year, it is not WiFi enabled, you basically connect it to your camera with the normal USB cable that came with your Iconia ... but their support kinda sucks and it has been under "BETA" status for well over a year now.

Click to expand...

You should check out dslrcontrollerby chainfire. Probably the best app for any sort of thetering and remote controlling application on theandroid market. It also allows for wireless controll between two android devices (via adhoc). Chainfire also actively answers emails and forum post over at XDA devs.

I wish someone would someone would release a slightly inexpensive wireless file transmitter myself. I guess it's a pipe dream for now.

Click to expand...

I had (and still have) the DSLR Controller, its also a decent app but I had a few issues with it freezing on my Acer Iconia 501A ... unfortunately this too has been under BETA status for nearly 20 months now (their last update was in September 2012) ... it does not work on all Android devices and you need special USB cable and/or adapters for it to work on your particular android device, but you can't blame Chainfire coz there are far too many devices and almost every device manufacturer "customizes" the OS to suit their hardware, posing a big challenge for software developers to come up with a stable app that works on all those android devices with different screen sizes and configs ... this is the reason I shifted to Apple devices - ok, lets not start a holy war on this issue ... it is my personal choice to go with Apple and I mean no ill will towards any Android users and I still have one Android tablet

Don't blame you. On the photographic front, it seems like Apple has the hands up despite what many people say or believe. Luckily for me, I haven't had any issues with DSLR controller (probably due to my phones and tablets having native USB support) and Chainfire has replied to my emails whenever I have had any issues with the software. That was a big plus for me.

Hopefully you find software that best suites your need.
