A good reminder to finally dig into the Servo customisation features of the 1DX; I quickly got comfortable with everything else the 1DX offers, but that's ... one heck of a large subject and coming from the 5D2 I still lack a lot of experience with advanced AF!

EOS Bodies / Re: Full Frame Vs Crop Sensor
« on: February 19, 2014, 07:19:45 AM »
My first and second DSLRs were also the 500D and 5D2, it was a great upgrade, build quality, handling, image quality ... everything except the AF (no, that's unfair, the 5D2's center point did really well in low light compared to the 500D) and frame rate. And yes, many lenses will behave better on full frame, although it depends on the lens and the criterion, for example vignetting is less of a problem with a crop sensor because you are not using the more-vignetted borders of the image circle.

The more I read, it seems that crop bodies have a singular advantage over full frame and that is the increase in focal length.

At the beginning it looks like an increase in focal length, but really you are just cutting away ("cropping") part of the image. The only advantage of crop sensors that is sometimes (!) relevant (except for price) is actually the higher pixel density.

EOS Bodies / Re: sotchi - canon prototypes
« on: February 18, 2014, 08:52:08 AM »
i know it sounds a bit crazy but i watch the games mainly because i want to spot canon prototypes (not much a fan of commercial sport events, especially olympia).

are some other crazys here like me who are more interested in the photographer crowd then the sport events?  ;)

It's spelled "Sochi".  I've not watched the Olympics very much...I liked the opening ceremonies, the light show.

It's spelled "Сочи". I don't watch any of it, the same old, year after year, and I trust that I'd read about any new gear on this site :-)

Is there some alternate meaning to 'fast zoom lens' that I'm unfamiliar with? The ad reads as if fast is a bad thing :o
Not really, the guy is saying that the lens is not as fast as others may claim, and that he has faster lenses, and therefore is getting rid of the 70-200 II, for being too slow.

And this raises a question.  If you really feel that Canon tries "to get away with absolutely the least they can for the most money they can", why in the world would you stick with Canon???
I'm not really the target of this, because I'm mostly happy with Canon, but let me say that in capitalism every corporation has to get away with the least they can for the most money they can because otherwise they could be sued by their shareholders. Unlike the customers, which can't sue them for not implementing easily done features. However Nikon, Sony and Canon are all corporations, so for me there's no big difference. I'm sure Nikon users are waiting for some feature that Canon products have just like we Canon shooters would like for example the zoomed histogram that even the entry-level Nikons sport. Anyhow, back to shooting with my quite nice 1DX, I've mostly stopped caring about it having less MP or DR than a D800, and even though I would prefer more MP, DR and less AA, I'm really like my Canon glass, the 135L, the 50L, etc :-)

EOS Bodies / Re: How can I choose between 1DX and 5D MARK III?
« on: November 06, 2013, 01:56:29 PM »
If money is no object, then get both.   ;D
Or get the 1DX for BiF etc. and keep the 5DII as backup and for light(er) weight hiking. For landscapes there shouldn't be much difference between the 5DII and 5DIII.

That's more or less what I did because the 1DX had a few features that I was really interested in; that said, I would also love to have the 5DIII's silent mode (the 1DX also has a "silent mode" but it isn't really silent).

EOS Bodies / New 1DX Firmware Version 2
« on: October 22, 2013, 07:43:13 AM »
Am I going crazy, or are they finally giving us a true Auto-ISO in M with exposure compensation?!?!?

That's a pleasant surprise!

EOS-M / Re: The rumored tele lens for the M

Moreover, if the solution to lack of EF-M lenses is to use EF and EF-S, then why even bother producing an EF-M 18-55 or 11-22 when there are adequate EF-S equivalents already?
One factor is the fact that the smaller flange distance allows smaller lenses only for wider angle lenses. (This is the "in a nutshell" of a very long explanation; for an example look at the 35L and a 35mm f/1.4 for Leica M-Mount; the difference in size is due to the 35L having to "compensate" for the larger flange distance of the EOS mount; I'm no expert on the field but I remember reading something about having to complicate wide-angle lens design once the focal length goes below the sensor diagonal (or some value that is a linear function of the sensor size)).

EOS Bodies - For Video / Re: 6d WORSE than 60d for moire/aliasing?
« on: October 11, 2013, 04:00:09 AM »
The 5D3 has little moire because of its strong AA filter. If the 6D has more moire because of not using all the pixels for video then it's just cheap. If its because of a weaker AA filter then hooray, I'd greatly prefer my cameras completely without an AA filter!

Fake would be in a studio or a zoo and trying to pass it off as if it were in the wild.  Fake is not setting up shots through painstaking planning. 
Interesting you say that, for I've had that exact experience. In the Adelaide Zoo about 10-15 years ago, walking around with a bunch of kids as part of some school-holiday daycamp thingy (something my then-gf roped me in to help with).
(...)
At least it sounds like they gave it an honest try before reverting to the zoo...

Third Party Manufacturers / Re: Nikon goes Medium Format?
« on: September 17, 2013, 10:10:07 AM »
Flash news, Nikon and Canon both introduce new medium-format camera systems with a single joint open-standard lens mount. Now THAT would be COOL!

The point of ETTR is to allow more light to hit the sensor.


No, the point of ETTR is to avoid blown highlights while not losing detail in shadows. It might mean less light hitting the sensor, if average metering was going to blow important highlights.


http://en.wikipedia.org/wiki/Exposing_to_the_right

In digital photography, exposing to the right (ETTR) is the technique of increasing the exposure of an image in order to collect the maximum amount of light and thus get the optimum performance out of the digital image sensor.


+1.  It's all about getting as much light as you can without clipping the highlights while reducing the shadows.  It's equivalent to an overexposure of around 1/3 EV.

You can't generalise ETTR in that way, whether and by how much it overexposes or underexposes depends on what the autoexposure does (since that's the frame of reference in this case) and on the concrete scene (the maximum difference between the "average" and maximum brightness).

A dark scene with one slightly brighter spot will need a few stops of overexposure; a normally lit scene with one very very bright object will need some underexposure.

So I'd say that Wikipedia is wrong; ETTR is a "technique" to ensure the best exposure without clipping the highlights. In some cases it increases the exposure, in others it decreases it. If ETTR were a simple overexposure or underexposure we wouldn't need a new term for it.

EOS Bodies / Re: An Update on the 75+mp Camera in the Wild

Klaus at Photozone and I have shown several times that  if one copy does not appear as it should we took another copy to test,  I tested 4 Canon 24-70 before I got one good example  and showed the test results  and so  did also Klaus  .
All brands have problems with the uniformity and quality, also Nikon
If I were reviewing a lens and I got a crap copy, I'd review the crap copy and give it a harsh negative review.  The fact of the matter is that a glowing of a review where three out of four copies are junk does not accurately reflect what a person is going to get when they buy one, statistically speaking.  If these manufacturers want to get good reviews, they should have better quality control.  This isn't rocket science.  They could trivially attach every lens to a test rig, measure it, and verify that it is within spec like pretty much every other professional hardware manufacturer does.  The fact that they obviously do not do this speaks volumes about their product quality, and I firmly believe that the reviews should reflect that lack of concern.
+1000!
This could be taken a step further by purchasing multiple copies, like now, but posting the review for the WORST out of the bunch! Or start reviewing one copy, and then see what the worst one that a reader of your's got is!

EOS Bodies - For Stills / Re: Why is metering not linked to AF spot?
« on: July 30, 2013, 06:20:07 AM »
It appears to be artificial product segmentation.

It seems to work in their favour, this feature was one of the reasons that made me get a 1DX over a 5DIII.

Of course some other people might have chosen a Nikon over a non-1-series Canon, we don't have the numbers.
