EOS Bodies - For Stills / Re: How strong is the hotshoe?

Yes, it's entirely sensible to grab your kit by the cheapest most lightly constructed part.

Clue,  The body and lens are metal for a reason.

I hate to flame, but this really is a dumb question.

I don't think it's a dumb question. My 580EX flash feels really strong, I had no idea there was a designed fail-point there. I had assumed that it was strongly built, so  I've grabbed my camera by the flash before, but I won't anymore. Thanks for asking this question!

As others have mentioned, if you're doing head and shoulders in a studio use f 5.6 - f/8 on a FF, and make sure the backdrop is 6 - 10 feet behind the subject.

EOS Bodies / Re: 70D and Dxomark....

I'd like my Canon DSLR to do everything better than any other camera on the market: ergonomics, weather proofing, durability, auto-focus, resolution, speed, battery life, etc,etc ... including DR .

Unfortunately no manufacturer has a camera that wins at everything, and yet somehow an army of Canon users are pumping out award-winning photographs and films.

I shoot regularly with two photographers using D800's, and I've yet to see either of them produce an image I like as well as what I get from my 5dIII. ... and they can't touch me on video.

Thanks for the video!

Can you compare the high ISO video performance of the two cameras (from 1600 to 12800) ?

EOS Bodies / Re: Canon 70D - DEAD SENSOR PIXELS! Im not happy :(
« on: August 30, 2013, 05:56:37 PM »
The red stuck pixel is back. I guess manual sensor cleaning will not get rid of it. Luckily, I got this camera at Amazon so I can order another and send this back when they get it back in stock or wait until the local BestBuy gets it in stock so it's easy to return if I get another one like this. I have a feeling it may be a common problem that people aren't seeing because of the subject matter or where the bad pixel(s) are located. It's been in a different place on the two cameras I have has.

Is it just in video or both video and pics?
I had to return two 5DIII's because of this problem. I had bright red pixel's at low ISO.

My 5DIII (third one) has no stuck pixels. I am really happy with it, but I find it disturbing that I had to go through several cameras to get a good one. I've had quality problems with 6 of the 7 Canon DSLR's that I've had/have :

40D Bad LCD
40D Bad lens mount
60D diopter wheel very loose and will not stay put. Also the rubber grip peels at the edges after about 1 year.
5DII bad electronic board, replaced on warranty
5DIII two bodies with red pixels on the sensors

My current 5DIII is pretty much perfect.

I tried the pixel remapping suggested above and it fixed my red stuck pixel issue, looking at a few shots and a 3 minute movie. Thanks for that info.

In video, the red pixels are easier to identify by videotaping a dark scene (no black), and moving or panning the camera. Any stuck pixels will be obvious as they pass across the scene (the pixels don't move).

Did the remapping fix the red pixels in video? I am really curious because I have read that it doesn't work for video. I haven't run into the problem myself, but if I do I'm hoping this is a realistic fix.

Take it back and get a new one, you'll just get stressed trying to figure this one out.

BTW ... I don't think pixel mapping works properly for video, so even one stuck red pixel can ruin video

I know everybody has invested in lenses and accessories, so jumping ship is not practical, but here is what that 3 stop of extra DR can mean (5D3 on top, D800 on the bottom):



Is there really only one image on the internet that DR people use. This is the same image that gets posted every time D800 shadow detail is mentioned. I'm starting to think this whole issue is faked

Lenses / Re: Bought 24-70 f/2.8 II -Soft, owners, please advice
« on: August 27, 2013, 03:19:18 PM »
Hey there,

so I went on and bought a new 24-70 f/ 2.8 II. The strange thing in China (where I currently live) is that they don't let you test the lens before you buy it - nowhere. So anyway, I picked one finally after searching the whole day for a good price - and to be quite honest, I am very disappointed.

Here are two crops, 100%, everything is on neutral, no sharpening.
First one is AF-Live mode where I zoomed in on the 24 using 10x magnification. Second shot is using the normal way.
Lightning is not so good, but since on a tripod and with remote control I don't see any problem using slow shutter speeds.
I used AV mode - strange thing is that life-view gives me a different meter reading.

Any advice from 24-70 owners will be highly appreciated.

PS: I am shooting with a 5D3, newest firmware.

Using live-view, 1/4 f/2.8 ISO50 24mm

lifeview1

Using normal focusing, 0.3 f/2.8 ISO50 24mm

lifeview2

Both pictures are shot in jpeg, L mode. I usually don't shoot RAW so thats why I keep testing like this.
I don't see any differences in those two pictures except the exposure, which means that AFMA can't help me - Do I have a "bad copy" or can I fix this somehow?

What is your focal distance? This lens is known to fall apart at close focus distance

EOS-M / Re: Mount EF, EF-S or L lens on EOS-M --- Your thought???
« on: August 26, 2013, 12:03:53 AM »
I like the M for casual shooting. It's good to have an APS-C camera with an f/2.0 lens in your pocket for $299.

But it is still too slow sometimes. Focus is a little slow, and the camera itself is sluggish. For example it takes about 3 seconds before you can shoot again even when you change from AE to M mode. Getting out of menu to shoot again is also slow. There's no C1-C3, so you can't save any setup conditions. The movie mode also is not separated, so picture profile in photo mode is the same in movie, just like all other settings.

I could go on, but for me the camera is just a good point and shoot that's awkward and slow and is small enough to carry for an emergency back-up.

I hope Canon doesnt give up on it. They should produce a really compelling EOS-M II, but the first version is worth about the $299 fire sale price, and it won't replace my 5DIII on anything but late night pub crawls.

BTW ... I bought a genuine Canon EF adapter on eBay for $89, so it takes all of my other lenses, but I typically just use it with the 22mm f/2.0

PowerShot / Re: Canon PowerShot G16 Announced
« on: August 22, 2013, 03:26:15 PM »
No articulating LCD--feckin' edjits! I'm keep my G11 until Canon wakes up.

Where's the fully-articulated tilt-screen??????????????????

On the G1 X. 

1/1.7" sensor? What gives? It is 2013. Have they not bothered to strip down a Sony RX100 to learn how to do this properly (I'm not even a Canon-hater, all my DSLR stuff is Canon).

Also the G1 X, with the 1.5" sensor.

Canon is just providing depth in the G series.  The G1 X has the screen and the bigger sensor, but it is slower, larger, and more expensive.  If you want a smaller and faster, and a little cheaper, you get the G16.  There isn't anything wrong with this, although I think that Canon has somewhat orphaned the G1 X.  The G2 X will probably get the wifi treatment, maybe GPS, and hopefully the new sensor-AF -- but who knows when.  And it will probably still have a slower lens than the smaller G's, based on my understanding of the lens optics.

If the G2X has APS-C sensor from the 70D, a 15mm wide lens (24mm FF Equiv), and a fully articulated touch screen, I'll be there. Otherwise I'm waiting on a EOS-M II or something new from Sony.

While I love the idea of a 24mm, I wish they would put out an updated 50/85mm art series lens first. I absolutely love my Sigma 35mm, a lens I was predisposed to hate (I don't like owning non-canon lenses, mainly due loss of value), but I was so blown away by the 35mm I would jump on a new 50mm the instant it was available. The currnent Canon lineup at 50mm is abysmal at best, so I am sure a Sigma 50mm would be every bit as popular as the 35mm. While I would like to buy an art series 85mm, I'm happy enough with my Canon 85mm 1.8 that I would not likely upgrade to it.

The 85 1.8 is a good value, but it's delicate. Mine took I minor hit and wouldn't auto-focus again. I'm hoping someone comes out with an 85 f/1.4 IS .

Lenses / Re: Can 24-70/2.8 II replace 35/1.4?
« on: August 17, 2013, 12:56:01 PM »
Don't want to sell my primes even when they are covered by my zooms.
I love my 35L and 135L, they have their place when light is getting tricky or I want to have that 1.4/2.0- look.
My 2 cents.

I agree... I have 16-35 2.8 II, 70-200 2.8 IS II, and 24-105 f/4 zooms, and I have the 28 2.8 IS, but I keep wanting bigger aperture. My only large aperture now is the 50 1.4. My 85 1.8 was damaged, and I tried a 24 1.4 several years ago but it didn't focus reliably on my 5DII. Now with the 5DIII I'm going to give the 24 1.4 another try, and I'd like a 50 1.4 IS and an 85 1.4 IS.

Large aperture primes provide opportunities for unique shots that are not possible on the zooms.

Close focus, something I really like at wide angles, is apparently a problem for the 24-70 2.8 II.
But close focus is a strength of the 24 and 28 2.8 IS lenses, and probably also with the wide 1.4's
You are right, close focus on the 24-70mmL is poor at best.  Its awful.  Fortunately, my 100L is good for close focus.  My 24-105 which I've kept is also good at close focusing.
There is never a perfect lens.

How close can you go at 24 mm on the 24-70?
It's mostly in the wide that I need to focus close

The MFD of the 24-70 2.8 ii is 380 mm; at 24mm even a bit longer.
The MFD of the 24 1.4 ii is 210 mm

So close to a 2x difference

MFD is not the whole story. My understanding is that IQ at MFD is awful, so to get good IQ you have to have a subject some distance further than the MFD.

I wonder how far away the subject needs to be in order to get that excellent IQ the 24-70 2.8 II can deliver?
