Lenses / Older L lens repair 400mm 2.8L II (non-IS)
« on: October 02, 2012, 01:41:28 PM »
I own the pre-IS 400mm f/2.8L II and see that it is not listed on the CPS repair eligible list. My lens is working great at the moment, but I am concerned that if the USM fails or something else goes wrong that I am going to have a very expensive paperweight. I am considering selling it while I can.

Does anyone know where I can get it serviced? Parts availability?

EOS Bodies / Re: Canon 5D3 vs. Nikon D600

5dmk2 and d800 same exposure time, f-stop base iso
5dmk2 developed in camera raw and DPP and d800 in camera raw so that details/information can  be seen equally in the white  house wall and in the white  towel  in front of the garden house =high lights reproduction.
Then we look in the shadows, low levels , an area is selected in the low levels and auto contrast is laid, auto contrast are showing  levels , details, noise in the selected area , no personal influence , photoshop is calculating  the signal level from the pixels values. This is the  results of  2-3 extra stops DR  in low levels.  And how to use it- it is up to the photographer and  the skills to use photoshop
PS
I have lent the  raw files to a number of talented members at dpreview , they  have  all checked  and verified the results by them selves.

Great comparison of noise at 100% scale vs. 66.7%!

I've seen good advice about what to try in the future, but regarding the photos you've taken...if you drop the exposure all the way on the RAW file is it possible to get the faces to look decent? If so, you might try double RAW processing the image in PhotoShop.

EOS Bodies - For Stills / Re: Adobe RGB or sRGB please?
« on: September 27, 2012, 08:42:41 AM »

I think you just made a really good argument for leaving the camera set to sRGB. It's the smaller color space so if you don't see any clipping in the tiny, questionably precise histogram in sRGB, you damn well won't have any clipping in the image when processing the RAW file.

Nah it just means you crippled RAW even more than you had to (although if all you ever care about is final sRGB output I suppose not).

I don't see how this would cripple the RAW output. The setting only affects the preview, so at worst you take a picture, look at the sRGB based histogram and decide the exposure was good, when it might have been possible to push the exposure a little bit more.

Now look at the converse situation. You set the camera to AdobeRGB, take a picture, look at the histogram and see that it is at the very limit of the cameras dynamic range...any more exposure and you would have clipping. Now you import the RAW and when output to sRGB find that there is clipping.

Honestly, the margin we're talking about (if not imagined) must be tiny.

Others have pointed out similar predictions for a comet in 1973 that turned out to be much dimmer. I'm not an astronomer but look forward to taking an amateur's stab at it should the predictions prove accurate.

Canon General / New comet spotted. Will be visible to naked eye in late 2013

"...on 28 November 2013, current predictions are of an object that will dazzle the eye at up to magnitude —16. That's far brighter than the full Moon."

You know, this has me thinking (a dangerous pasttime, I know...).  I've often made the argument that the in-camera jpg settings do matter if you shoot RAW, indirectly, because the in-camera settings are applied to the JPG preview image that's reviewed on the LCD and used to generate the histograms.  So, to the extent that you make exposure decisions based on the preview image, histograms, or blinking highlight alert, those JPG settings matter. 

I wonder...what is the gamut of the camera's LCD, would sRGB vs. Adobe RGB make a difference in color channel saturation, a difference in the histogram or highlight alert calls, etc.?

I think you just made a really good argument for leaving the camera set to sRGB. It's the smaller color space so if you don't see any clipping in the tiny, questionably precise histogram in sRGB, you damn well won't have any clipping in the image when processing the RAW file.

I do 99% of my RAW conversion with Aperture because it does a good job and is easy to use, however I keep DPP around because sometimes I can get a better result on a tricky image.

Also, don't forget to grab the update: http://www.usa.canon.com/cusa/professional/products/professional_cameras/digital_slr_cameras/eos_7d#DriversAndSoftware

Choose Mac OS X and then OS X 10.7 (regardless which version  you are running)

How Digital Photo Professional report it? That should be your true test.

My best guess would be that a change to the way the new firmware saves lens info in the RAW file isn't being correctly interpreted by Aperture.

I'd report it here: http://www.apple.com/feedback/aperture.html

I love my 5D Mk III, but for the price it should have been something more.
-Canon had touch screen technology ready a few months later in the T4i... I would love pinchy/zoomy/swipey navigation through my shots.
-Build cost estimates for the Nexus 7 tablet show the Wifi/BlueTooth/GPS chip as costing $11...come on Canon, this the new 5D, INCLUDE IT!
-USB 3.0?
-SD-UHS?
-Interval shooting?

Besides pros, the market for the 5D MK III is well-healed enthusiasts like myself. We live and work in the gadget age and expect high-end gear in 2012 to have all the bells and whistles. The 5D Mk III met my requirement of 5D MK II IQ and 7D speed, so I preordered it immediately. However, I really hoped it would be something next-level. Canon missed an opportunity to have another wild hit and I think that is where better leadership could help.

As others have said, the camera was probably set so that you must push the "AF On" button on the back of the camera for AF to start. Some people prefer to separate focusing from light metering, both of which happen by default when you half-press the shutter button. When set this way,  you can aim the camera at your subject and press AF On to focus, then recompose the shot and touch the shutter to light meter the scene as recomposed before taking the picture.

Anyone think a preemptive petition is in order? Maybe if Google sees some early groundswell in support of the plugins they will be less tempted to axe them.
