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?

Third Party Manufacturers / Re: Nikon D750 to be Canon 5D3 competitor?
« on: September 08, 2014, 12:07:17 PM »

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."

Lenses / Re: Canon MP-E 65 f/2.8
« on: August 30, 2014, 04:34:28 PM »
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  :'(

EOS Bodies / Re: Are These The EOS 7D Mark II Specifications?
« on: August 23, 2014, 04:38:44 PM »
...but I do think Canon should have demonstrated that they are still capable of competing on the sensor IQ front.

 Still...it'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.

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  :-\
