EOS Bodies / Re: One other hoped-for feature on the 7D2
« on: July 29, 2014, 07:47:21 PM »
on the 5diii and 1dx you can program the set button to activate ISO on one of the wheels.  Forget auto ISO since you will ultimately get more noise than you want.  Use full manual and adjust ISO with set button and top wheel.  I've even learned to fire the shutter with my middle finger when speed is of the essence.

Software & Accessories / Re: Rain protection for 5D3 and lens
« on: July 14, 2014, 02:10:44 PM »
I have a 5D mark 3 and use it for airshows with a 70-200mm f2.8L IS II or a Tamron 150-600mm f5-6.3.

Looking for some rain protection that will cover both lenses (whatever one is attached at the time) and the body as I often have to shoot in rain and don't want the camera and lens getting soaked.

Any suggestions without breaking the bank too much?

In the past I have relied upon the "wife+umbrella" technique but wife will be missing from the next few airshows!

Cheers
Scott

I too have bought a number of rain covers...cheap and expensive.  For the 5D3 and weather sealed lenses, I now just use a towel or two.  Throw them over the lens and body and roll with it.  I've used that many times shooting soccer games.
 
If you end up being in a real gully washer, your not going to get much in the way of pictures anyway and thats the time to bag it or pop open the umbrella and wait it out.  Gotta dry it all out too before long term storage...no caps in this stage.

EOS Bodies / Re: The new APS-C Champ. (My wild guess).
« on: June 23, 2014, 10:35:10 PM »
Since most of the rumors coincide with “new” sensor technology, and significantly lower noise; My guess is that Canon has further evolved the Dual /( Multi) CMOS technology to acquire more light, while maintaining resolution???

Perhaps distributing pixels over multiple sensors, with a method of acquiring “even” light to each sensor element.   ( The only “current” manner of lowering APS-C noise is to reduce resolution/pixel-count.

Canon has a history of “field testing” new technology in lower priced cameras, hence the 70D.

I do expect that the 7D MK II will be a big improvement over the mk I. 
I do not expect more than one sensor in the camera, why would they use multiple sensors?
 
You cannot acquire more light by splitting a pixel in pieces, they gather photons according to the area, so you receive approximately the same number of photons overall.  The 70D does not acquire more light, but uses the dual pixel for phase detect autofocus.  Otherwise, its the same as other Canon sensors.
 
The split pixel technology potentially allows some other tricks like improving DR, and probably some that I'm not aware of.


Maybe dual sensors could be used, but not for what you think.  I could see a use to have multiple sensors, 1 for imaging, one for AF, one for the hybrid viewfinder (or maybe a dual pixel sensor that can perform AF and feed the hybrid viewfinder.

I would be willing to bet that the new models will just do away with the phase detect sensors that we know and have loved for all of these years.  A better full time contrast detect with higher speed AF with focus points anywhere across the sensor field.  Higher end models would be fully programmable on AF patterns.  Lower end would be fixed patterns.

We have already heard rumors of the 7D replacement having a larger "bump" on top.  How about a specialized prism that can split the image into multiple paths to multiple sensors.

It just seems to be the next logical progression from the dual pixel technology.

EOS Bodies / Re: New Sensor Tech in EOS 7D Mark II [CR2]
« on: June 20, 2014, 12:52:05 PM »
This has been another informative thread -- I'm learning a lot. Thanks guys and gals, especially jrista and others on the in-depth tech talk. Very cool stuff.

My guess is that if there's a big improvement in image quality from the sensor, it's probably produced on a new fab. That could also explain the delay in getting the 7DII out the door and perhaps the absence of patents that would point to something totally new.

On the patents things, there is another way they could bring something "totally new" (at least for Canon). They could license or buy a patent from another company. Any thoughts on this? Does Canon take too much pride in their own development to do this? Do they not need to because of the technology they're already working on? Is it still just market dominance that allows them to not need to make a huge leap? (Something tells me that while market dominance might mean they don't need to release a new leap in tech, it doesn't mean they aren't furiously working on developing new tech all the time.)

Anyway, I'm still guessing new fab, but what do you think? Any chance some other company's patent technology shows up in a new killer sensor for the 7DII?

Not sure how informative all of the opinions actually are.  I would be more interested in the opinion of the guy testing it at the world cup.  Short of that, all I want to know is when I can place my pre-order.

Technical Support / Re: 5D3 Focus Screen Replacement - Alignment
« on: June 19, 2014, 10:58:54 PM »
Thanks, that is very helpful. Do you think removing it and blowing on it with a Giottos Rocket Air will be harmful? I would also like to confirm it is a mark on the focus screen and not somewhere else. Maybe looking at it with a sensor loupe?

I've found the OEM part for $15.88 shipped from http://myfriggincamera.com/store/. It seems easy enough to replace if I don't have to worry about shims.

What does the superfine Matt do for you? Better manual focus? I would not mind some kind of improvement in that area with something like a split focus when I'm manually focusing.


If it's an OEM screen then you wont need to add/remove/replace shims.  Even the screens at the site I posted are actual OEM screens that have been modified and put in kit form to work in the 5Diii.  Although I'm note sure it yours is actually a 5D3 or not.  They have ones for other models.

I would not deal with blowing anything into the camera body at all.  There is so much crap that is collected at the bottom of the sensor due to ultrasonic cleaning that a puff of air could lodge dust into the AF sensor.  As I stated I would just replace the screen or have Canon do it.  There is a LOT of risk in doing ANYTHING to clean it other than replace.  Even then there is some risk that dust will get on the new screen during installation.

I chose the superfine matte to allow me to get better focus on my faster lenses, particularly my 100 L macro.  However it does darken the view a bit and it's bothersome in bright sunlight.  I believe somewhere on their website they state the amount of light loss with the screen and that equates to a loss on your metering and hence overexposure.  It's the price we pay to use a different screen.

There appears to be either a small scratch or a hair that won't move. In reading about the subject, I see that this screen is very fragile and can be easily damaged by cleaning it. The hair/scratch is not in focus and has always been there just off the center focus ring. Since it is not in focus, I presume it is on the face of the focus screen? I should have taken care of this when I first noticed it, but thought it just needed to be cleaned. There are also now several small hairs that are in focus (damn cats). Can I remove the focus screen with the proper tools (JIS screwdriver, plastic anti-static tweezers), blow it off and install without affecting alignment?

None of these show in photos, so my only worry is resale value. I asked CPS twice to clean this mark and it returned still in tact and no word on what it is or what they did or whether they even looked at it.

I want to know more about the alignment and using shims. Would a stock replacement part number ( CY3-1655-000) require shims and advanced equipment to adjust the alignment or are the shims that Canon installed OK for any stock replacement? By that I mean are the shims based on the camera, the focus screen or a combination of both?

Again, my only real concern is resell value as anyone looking through the viewfinder will see this mark and several new hairs and reduce the value - or not even buy it. I may not even sell it, but just looking to the future possibilities.


So generally speaking the focus screen is not cleanable.  Any attempt to clean it will just deposit more dust somewhere else which is why Canon likely just left it.  Next time you should just ask them to replace it and not to clean it.

There are 3rd party focus screens available and they come with the tools and everything you need to do it yourself including shims.  The shims are used as spacers to adjust the position of the focus screen in relation to where the camera is focusing as in focus is off when you manually focus any lens.  Generally you dont need to mess with shims as they are added at the factory.  Sometimes they are needed when you use an aftermarket screen.

I got my super fine matte screen at http://www.focusingscreen.com

I lose about 3/4 stop on exposure in metering so everything is generally overexposed by that much.  However at least on the 5DIII I like that better for the way I shoot and post process.

I hope that was helpful.

Well lots of advice from everyone.  However i will say that afma will not work as expected with the setup that you have.  The camera will ultimately use the ruler in some af calculations.

The best way without buying reikan focal (and i have never had much luck with Focal) is to tape a full sheet of news print on a wall and take 5 shots at each major afma setting 0 5 10 15 20 and 25 as well as the negative ranges.  Use 100% view on a computer to evaluate the images.  Once you determine the clearest ones then you can do then same + and - for every afma step 5 up and 5 down from that major setting.

Dont eval on the lcd screen or you will never get it right.

Another factor is to focus at the farthest distance your setup will allow.  Some lenses also have different afma settings depending on your focus distance.  Quite annoying.

Hi Folks.
Is there anyone that doesn't want AFMA? I know a few of you say that you need no AFMA on your lenses, but when you do get a lens which is not perfectly matched to your camera you will find it invaluable.

Cheers Graham.


But unless he really needs AFMA (and maybe he does - I have no idea),

particularly when you use your lenses wider than f8.

Do you guys know if ML does Focus bracketing (very helpful for Macro for example).

Yes, I know. Yes, ML does it.

Btw concerning easy installation: There is an implicit reason for this not being 110% advertised, next to the devs hating to write docs: If you cannot install ML with the current procedure you most likely won't be happy with it, it's not completely "works out of the box" and does need some getting into.

Id be happy to work on docs over the summer.  July timeframe.  Would need a path to get additional info on some functions and settings.  I'll drop you an email in private and we can see where we are and where we want it to go.

Extremely kind of you !

i am  a big ML user and not a developer.  Personally i could care less about in camera documents.  i usually carry all of my gears canon docs on my tablet.  though i could concede that a camera function should have some kind of description.  such as "dual iso - single shot HDR module".

I used to borrow a T3i from my brother. Now I have saved up some money to buy a camera body for myself. I dont wanna use a rebel body coz my friends are all semi-pro bodies user. They look great and are more sturdy in their built.

For the money I have, I can afford a 50D, 60D or a 7D body.

Locally in Toronto, I can grab a 50D for $400, a 60D for $550 or a 7D for $750.

I made some inquiries responding to some CL ads and got some exciting responses.

1. A 2 years old 7D with under 10k actuation with original everything for $750. It comes with a 16gb Cf card as well. I like the built, the speed and the badge. That's my no.1 choice.

2. A 6 months old 60D with may be 4k actuation with 2 years extended warranty. No card but come with an additional third party battery. Seller told me he bought it during last boxing sale for $800 plus tax with 18 200 kit lens but now will keep the lens and sell the body for lowest $530 to me. The good point is the like new condition and warranty. But it is not the 7D and no AFMA if I need it.

3. A 50D with 14k, seems well used. Asking $450. Obviously, it's least attractive to me.

My camera will be mainly for landscape and portrait shooting. Little chance to do sports and wildlife etc at this moment. I may start learning to shoot video as well. I have access to some nice lenses. Family members are generous to share. I will buy a few primes later.

Then. Which camera body should I buy?  Which  one will hold better value? I don't want a T4i, T5i  or an old FF 5D and I can't afford
A 70D. My choice seems limited. I guess I will go for one of the above.

Help me with my choice please.

Of those three i would choose the 7d.  It is the best choice ofmthe three and will suit you well when you switch to video.  The 7d build and firmware is much more capable than the other consumer models.  The 7d may come down in price later this year when the 7d mark ii is announced.  If you dont need it right away then wait a bit and see.  Otherwise just buy it and enjoy shooting.

EOS Bodies - For Stills / Re: Rant about 5DIII
« on: May 31, 2014, 10:48:32 PM »
Never thought I'd be writing this, but I want to write it and get it out of my system so I don't have any more ill-feeling left about this little guy:
1. Truly surprised about the difference between 8fps and 6fps. I was shooting a commencement ceremony and trying to get the 'toss the mortarboards' shot. Boy, was it getting frustrating catching the mortarboard while still within the frame (and yes, I started clicking even before it was being tossed). Nothing like this with my 7D. Could the frame rate be restricted under certain conditions?
2. The lack of AF point illumination in Servo mode is very annoying. With dimly lit subjects in a mostly dark background, I kept losing them. And I had to stick with f/2.8 because I was using 200mm (so at least 1/250) and ISO 1600. I know pros would be fine with these, but I was terrified I shall miss the moments by focusing somewhere else...
Ok, I'm done. It was all right eventually. Just too nerve-wracking at the time.

So yes there are other conditions that can affect frame rates.  Many of the settings can slow it down, particularly those that wait for focus before firing the shutter.  In low light the af can slow down and hunt more often.  Also ive noticed a condition at least when using a grip that if the battery is less than 50% drive mode slows way down.  Dont know if thats the case without the grip as i always use one.

So a couple of things that can help you out.  I comfigre the depth of field preview button (the one in front by your grip fingers) to toggle between servo and one shot.  When im in a situation where servo is not cutting it either with af hunt or inability to see af points, i just push to toggle one shot and get the shot.  You can release it fast enough to go right into drive mode once you have your af point where you want it.

Not ideal but it does help quite a bit.
