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.

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  :'(

EOS Bodies / Re: Are These The EOS 7D Mark II Specifications?

...but I do think Canon should have demonstrated that they are still capable of competing on the sensor IQ front.'ll suck, if the 7D II really doesn't hit with a better sensor, to have to wait ANOTHER couple years to see if Canon is going to do something on the sensor front. :(

Hate to say it, but "couple years" may be being too optimistic seeing how Canon obvious does not read or care about  Canon Rumors  :'(

Oh, and Photography only.  No video, or plans to go that direction.

Any thoughts?  Thanks in advance.

I would not get a high end gaming laptop for photo editing, since a lot of your money will go towards a nice video card for gaming, which is not all that relevant for photo editing.  My laptop has the Intel video card AND an Nvidia card, and even using Photoshop 6 with 36 GB RAW files, the graphic card doesn't even kick in (Nvidia Optimus function). 

Also 15.6" screen is just not close to being adequate for photo editing.  I bought the Dell 17R SE 17.2" laptop with "full HD (1920x1080)" screen, then installed a Sandisk Extreme II 480  GB SSD.  This was the best 17.2" screen I could find that covers essentially all of sRGB color space.  There is an extra hard drive bay for a second drive if you want.  This setup is lightening fast for photo editing with very fast Windows startup times. 

Reviews / Re: Tony Northrup - D810 vs. 5D Mk3
« on: August 08, 2014, 04:18:41 PM »
If i had to start over today, i'd go with d810 over the older 5d3.  But i don't want to go through the hassel of selling all my lenses so i'll wait to see how Canon responds.  Competition is great for all us consumers and Canon could use a hard kick in the butt like this to start stepping up.

This is probably how most people feel about D810, myself included.  If I did night photography for a living or printed huge landscapes, I might actually switch from 5D III to D810, but otherwise, there really is no pressing need to switch, given how I still prefer the Canon lens lineup and own many. 

A very detailed, thoughtful review of the interesting Pentax 645Z, with comparisons to Nikon D810 even and a serious effort to look into video capabilities.

Canon General / Re: What do you Cheap Out On?

Long ago, I used a Salt container, Pringles container, and a milk jug.  I now have more expensive versions but less fun.

Lenses / Re: How many years before we see a 50L II
« on: July 26, 2014, 03:11:12 PM »
It's actually the field of curvature and is especially prominent at close distances from about f/2.8 to f/4.5.  The lens will back-focus and there is pretty much nothing you can do about it.

What, people use the 50L at narrower than f/1.8 or so ??  ;)

Lenses / Re: Selling my two Zeiss lenses. Your advice?
« on: July 26, 2014, 03:05:49 PM »
Canon... has very similar qualities and has autofocus, is lighter and cheaper.

That is exactly how I feel about Zeiss lenses I've had in the past.  They are sturdy and cool-looking, but they don't do anything Canon lenses can't do (and Sigma it turns out), and they are heavy, expensive, and lack auto-focus  :-\

Third Party Manufacturers / Re: A7r Arrived - Meeting New Buddies
« on: July 16, 2014, 08:24:07 PM »

I definitely had to learn this the hard way even though it was something I fully suspected prior to ordering. Lol.

Anyhow, based on my very brief experiences so far, I'm finding that the only thing I really enjoy about this thing is the manual focus aids. Quite honestly, I wonder how much more I would like the xt1 if it were possible to mount EF lenses and maintain aperture control.

Funny thing is as soon as I returned my A7R, I installed Magic Lantern for the first time on my 5D III, including the manual focus aids.  I don't understand why Canon doesn't provide focus peaking, etc, in stock firmware  :o

Looking back, what I really enjoyed about my Sony experience was the FE 55mm f/1.8 lens.  Oh, that was a sweet lens; Wish Canon had a 50 mm at that price with comparable color, contrast, sharpness, bokeh, and AF accuracy.  Its compact size was fantastic, too, but I guess Canon's version cannot be as small due to the mirror box  :'(

-IQ is not noticeably better than my other rigs as some would have you believe.
-The DR madness has yet to make a difference in any of my first 100 shots. I did however deliberately under and over expose a few shots to see how flexible the files would be in post (they were very clean and resolved a lot of detail). This however doesn't really translate into better photos as it was only a real tangible benefit when I deliberately used the wrong exposure for my shots. Time will tell if I actually enjoy having the extra DR as much as I hoped.

Yup, these are things one cannot convince oneself without first-hand experience.

I, too, remember taking an underexposed shot from A7R, pushing the shadows up more than I ever do, feeling impressed and giddy.  However, this was totally useless in my normal shooting with competent exposure.  Same thing with 36 MP resolution; it's neat to zoom into little hairs and such, but it didn't improve my photography at all. 

THE Most important information seems missing:  improved AF speed with the Mk IV adapter? 

This is disappointing as well:
"A third party zoom lens may need to be registered with the Smart Adapter first in order to detect its maximum aperture. Autofocus is disabled for most third-party lenses.
Only Canon-branded lenses introduced in or after 2006 are officially supported. Autofocus may be disabled for older Canon lenses and most third-party lenses, including most Sigma, Tamron and Tokina lenses and all Contax N lenses modified by Conurus."

The auto-gamma is one single massive improvement in V4, in my opinion.

Wow, DPP 4.0 Auto-Gamma has been an eye-opener for me.  I have never liked the results of "Auto" anything previously, including Photoshop's "Auto" tone, contrast, and color, but DPP 4.0 Auto-Gamma is giving me some well-judged, natural-appearing results.  I just used it for a set of photo's shot under mid-day sun by poolside with strong sun highlights and building shadows, and Auto-Gamma gave me fast, natural results, which I copied the recipe and pasted on to others for a very efficient post-processing workflow  8)

Lenses / Re: Canon 135L F2.0 - Am I expecting too much
« on: June 29, 2014, 01:22:00 AM »
135L is a wonderful lens but getting rather old.  Use Canon DPP's DLO (Digital Lens Optimizer) which is the best I've found at correcting aberrations, improving clarity, etc.

Someones (Damien Demolder ) personal opinion on the D810:

Just IMO, but that article just seems to be trying very hard to come up with all kinds of tiny reasons to justify why the D810 is the latest and greatest, even better than the "best-ever" D800/E, making it greatest-than-greatest-ever.  :P
