Third Party Manufacturers / Re: Great interview about the Samsung NX1

Well, scale up that BSI 28 MP aps-c sensor to 42 MP full-frame, then we might have something really intriguing to talk about  :-\

First impressions, the 5D III takes warmer images, with more vibrancy than the A7r. However, I feel the A7r colors are more realistic (this is when using them on Camera Neutral, and importing with Camera Neutral in LR).

That's a little unexpected, as others (including myself) feel A7r colors are a bit further from neutral than Canon.  I personally found both deviate from what eyes perceive but Canon closer than Sony A7r, coming in from almost opposite directions. 

Since installing Magic Lantern 1.2.3 on 5D III, I have noticed that my files shot at 0 EV exposure comp are wrongly tagged as either +1/3 EV (seen in Digital Photo Professional) or "+1 Step" (in Windows Explorer window, flickr). 

Files shot with +1/3 EV are wrongly tagged as +1/2 EV (DPP) and "+0.5 Step" in Windows explorer and +1 EV in flickr.  A files shot with +2/3 EV actually showed as nonsense under flickr EXIF,  "-1/2 EV"

Has anyone noticed similar problems since installing Magic Lantern 1.2.3. on 5D III?  Any way to fix this or could this possibly be some other issue, although the only change has been Magic Lantern?

Below are examples:

the IQ is a lot better then the 7D and I compared it to the 1dmkiv and it holds its own against that camera.

Since 7D II RAW images are unlikely supported yet, are we basically looking at the difference between in-body JPEG engines?

Is there difference between Mac and Windows?
On my Win 8.1 machine with Photoshop CS 6.0, I do not get the check box "Tone in ACR."  In its place is check box "OK," which then gives me an image to view in photoshop but no step to tweak things in ACR, such as shadows  ???

Still waiting for Nokia's 1020 successor to come to Verizon myself for photo goodness  :D

Speedlites, Printers, Accessories / Re: YN-622C and 580EX II MAJOR issues
« on: September 11, 2014, 09:17:43 PM »
I have four YN-622Cs and three YN-568EX II flashes for my 5D3.  zero issues -- the system doesn't miss a beat and has worked flawlessly.

When my 580EX died I decided to go with all Yongnuo hardware.  What would have cost me nearly $2K in Canon cost me under $700.

I have a bunch of YN-622C's which I use with Canon 580EX II, 430EX II, Yongnuo 578EX II, which all work with no issues. 

I will say I cannot say the same for Pixel Kings, which definitely had issues.

Lenses / Re: DXOMark Reviews Zeiss Otus 85mm f/1.4
« on: September 10, 2014, 05:26:40 PM »
I have to but ask for whom is 85mm Otus meant? I mean, where is the significant difference (when there is significant PRICE difference) in optical perfomance to its peers?

Well, according to Mr. Thein at the link review above:

"I’m sure many keystrokes will be wasted to explaining why alternative X at $1000 is better. If you have to even ask why, this is not the lens for you."

Nice, eh?

Sums up Sony nicely for me, not a company with the right mentality for any kind of long term vision beyond selling the next cool gadget.

This is a real shame for consumers because Sony does make some cool gadgets.  Sony exec's need to pick out a few notable products to market and STICK with long-term, along with proper lens/speedlite/trigger/accessory support.  As things stand right now, one can buy a cool Sony camera, and before he even had a chance to even fully discover the lack of proper accessory support, the next cool camera has been introduced  :'(

For goodness sake, Sony is still selling the HVL-F60M speedlite without addressing the clearly-reproducible overheating issues Sony customers have been complaining about for a year and a half!

Personally, if I owned Sony stocks, I would be selling them pronto  :o

PowerShot / Re: Review: G1 X MK2 by DPReview
« on: August 31, 2014, 02:47:16 PM »
that the sensor performance is reported to be the same or slightly worse than the G1X sensor is a bit disappointing of course.

It's the usual Canon Sensor story  :'(

Quote from DPReview:

"These examples (and our test scene on the coming pages) suggest that the RX100 II's sensor is so much better than the G1 X II's that it cancels-out much of the dynamic range and high ISO noise advantages that the G1 X II's larger sensor should bring...

Overall, though, the larger sensor in the Canon is much of the reason that the camera is so much less pocketable than the Sony, yet the full benefits of that additional sensor size are not realized: the Canon's image quality advantage isn't proportionate with its greater bulk."

MP-E 65 is a beast of a lens.  Having no focus ring and having to move the camera back and forth to focus takes some getting used to, not to mention the extreme stability needed at high magnification. 

Frankly, I find my Canon 100L like 10x easier to use, so I end up using the 100L with an extension tube to boost the magnification beyond 1:1 a bit.  Still, if one loves a challenge..

Photography Technique / Re: Is RAW worth it?
« on: August 25, 2014, 08:36:40 PM »
I only shoot RAW for all the reasons enumerated before, and I will add that it's even MORE imperative to shoot RAW on smaller-sensor cameras such as Canon S95..S120, G series, etc because the inherently worse high ISO noise, less robust metering and AWB means much higher chance of saving photo's with RAW.   

Speedlites, Printers, Accessories / Re: Laptop Editing - Best Setup
« on: August 24, 2014, 01:27:08 AM »

Are you sure about that on all systems? I think that is how it used to work.

I personally believe that depending on what card you have and what system you have it does switch automatically.

I know mine does.

Nvidia Optimus, as it comes, does switch automatically, but one can go into Nvidia control panel and select to use the Nvidia card for each particular program. 
I have tried this with Photoshop in past, and unless one is doing 3D rendering, Nvidia card does not speed things up for usual 2D photo editing.  Using the Nvidia card does make the laptop run hotter, resulting in the fan kicking in faster and louder  :'(
