Neuro, you had me up until that "ship is sailing along fine..." stuff.

Not trying to single you out, because I know you know better and I know you aren't guilty of the sin I'm about to attack. But, I can never figure out why otherwise intelligent people think a multinational, multi-billion dollar, profitable company is stupid.

Far from it.  My point is that Canon's current strategy is working.  They are doing their R&D, developing new cameras with improved features, releasing them into the market, and those cameras are selling like gangbusters.  I don't understand why otherwise intelligent people are clamoring for Canon to do something different, and be more like their competitor that isn't doing as well as they are in the market.

My point was not "the ship is sailing along fine," so Canon should be complacent.  They clearly have a strategy (ship), and are executing on that strategy (sailing), and are successful at it (sailing fine).

Also, do note that I did suggest that behavior might be short sighted.  I'm well aware of the parallels to Microsoft, another conservative company.   Just because it happened once, doesn't mean it will happen again; by the same token, just because it happened to another company doesn't mean Canon will learn from that lesson.  Usually, changes like this don't happen overnight.  Obviously, Microsoft did not respond to those changes appropriately for their business.  It remains to be seen how Canon will respond to a declining marketshare, but of course, first that marketshare has to actually decline. 

We heard all of these arguments about the D800, and the 5D Mark III is apparently outselling it by a wide margin.  Now the D7100 is the best thing since sliced bread, and while is does seem like a well-spec'd camera, I suggest we wait and see how well it sells, compared to a camera Canon may or may not release, before we declare victory for Nikon and claim Canon 'had their ass handed to them'.

Hopefully Canon is very scared - and taking Nikon's recent R&D push seriously.  They need to respond immediately...

Respond to what?  Sorry, but no, they really don't.  To those who say, "Nikon is handing Canon their asses," or "Canon should be scared," understand that at the most fundamental level, camera sales are what matter.  The finance and marketing divisons within a major corporation, especially a conservative one like Canon, are the voices that determine the ultimate output from the R&D side of the organization, in part because they control the input (i.e. funding) into that R&D. 

As long as Canon continues to sell more cameras and lenses than Nikon, the finance and marketing folks will continue to say that the ship is sailing along fine, it ain't broke and there's nothing to fix.  Is that short-sighted?  Possibly.  But as I've pointed out before, DxOMark has some pretty convincing data showing that from a sensor IQ standpoint, Nikon/Sony have been spanking Canon for several years now.  Has that pushed Canon to 'wake up'?  No - despite their 'crap' sensors, Canon has gone right on gaining market share at Nikon's expense. 

What Canon has done, consistently and successfully, is sell entry level (Rebel/xxxD) cameras to more people than Nikon.  We can debate up the wazoo about which $1200, $3000, or $6500 camera is "better" (whatever the hell that means, if it's even relevant since many of the people debating this aren't buying these cameras anyway).  But both Canon and Nikon sell far more entry level cameras than everything higher up in the lineup combined.  The fact that Canon is winning at the base of the pyramid means that more people are buying into their system, and that translates right on up the lines.  A bigger base means a taller, more massive pyramid.  While I'm sure there are exceptions, very few first-time dSLR buyers buy a $1200, $3000, or $6500 camera.  But they may spend that much on their second dSLR, or their third...and if their first one was a Canon (which by the numbers, it is for a majority of the market), odds are their subsequent (more expensive) dSLRs will also be Canon.

Why do people use shift lenses to capture stitched panoramas?

I'm not at all sure that most people buy TS lenses for the primary purpose of capturing stitched panorama.  While a TS lens can be used in a limited way for pano shots, it seems more of an opportunistic and incidental use.  As stated above getting a real multi-row pano setup offers much more flexibility for creating panoramic images.

...it doesn't mean that my opinions are irrational.
Price IS an issue for me, and based on ALL factors regarding cameras, i haven't been too thrilled with Canon's releases.

Your opinion was quite rational, as was your decision to switch to Nikon.  Personally, if my main purpose was to shoot landscapes, I'd be shooting with a D800, 14-24/2.8G and a PC-E 24mm.  Put that in a fanboy pipe and smoke it.   :P

The problem is when someone (and you're not the only one who does this) takes a statement like, "I think the recent Nikon dSLR releases are much better than the recent Canon dSLR releases," and somehow translates that into, "Most people think Nikon is dominating Canon."  First off, your opinion is not everyone's opinion, or even most people's opinion.  My opinion is not everyone's opinion, either, for that matter.  That's why I often bring up sales figures - it's an aggregate way of assessing everyone's 'opinion' based on their buying choices.  Sure, there are lots of factors that go into those buying decisions - features, cost, compatibility with current equipment, what their friends use, etc.  But it's an objective measure, unlike all of the hot air (or electrons, as the case may be) that we read on internet forums.

Another problem is the evaluation of the camera in isolation, or worse, basing an evaluation on sensor performance alone.  You state ALL factors regarding cameras, but both a camera and a lens are needed to take pictures.  Sometimes, a flash is needed, too.  It's the 'camera system' that takes pictures, not just a camera or a sensor alone.  So, it's important to view it in that light - consider your overall needs and budget for a system, and buy accordingly.  If one brand offers the best body in the world, but lesser lens choices, that's something to be aware of...

Finally, most of this really doesn't matter.  Sure, there are a few examples of images that can only be taken with Canon vs. Nikon gear (MP-E 65mm and 17mm tilt-shift shots, ultrawide shots with an image-stabilized lens, etc.).  But for the most part, it's much less about the gear itself than about the person using it to make images.

How come it's pentamirror,it says pentaprism on Nikon official website

Thanks, that makes more sense (and is why I questioned the person who posted that it was a pentamirror).

The sad thing is that Nikon is basically dominating all matchups(definitely on the lower end), at least in terms of specs, public perception(I understand pros love Canon for a reason, etc, i'm just saying.)

So, you're saying that "public perception" is that Nikon is "dominating" the matchups?  Is your definition of "public" taken to mean, "People who frequent internet forums devoted to Nikon cameras and people who frequent internet forums devoted to Canon cameras for the primary purpose of trolling?" 

Because the "public" who actually buy dSLRs, as opposed to those who just write about them on the internet, seem to buy a lot more Canon dSLRs than Nikon dSLRs, which is why Canon has been and, as of the latest available data, still is "dominating" the market.

I'm just saying...   ::)

Lenses / Re: Why aren't zoom lenses faster than 2.8?
« on: February 21, 2013, 08:52:04 AM »
It is quite easy actually. If you want to know what size it would require just divide the focal length with the required f-stop and you'll see what size the front element diameter would be. So, for a 100-400mm f/1.2 the front element would be 33,3cm in diameter. 

Actaully, that 'rule' applies to telephoto lens designs but not all lens designs.  Else, the front element of the 16-35mm f/2.8L would be only 1.25 cm in diameter.

The D7100 sure sounds like a good option for sports/wildlife shooters.  If only Nikon had an optically good 400mm f/5.6 lens (prime or zoom) to go with it.  ::)

Any idea why ts lenses does not have integrated collars, so this could be done by simply attaching the lense to a stand, then shift the camera around?

Probably because the main intention of shift is to correct perspective, and in that case, you want to shift the lens relative to the camera. As I stated above, using shift to create a panoramic shot negates the ability to correct for perspective in that shot.

I'm sorry but that particular comment is referring to shifting a normal lens, when a rail for panos is definitely required to avoid the different perspectives from moving the camera. I'm not sure you are getting the idea about what the shift function on a tilt+shift lens actually does. The camera stays immobile, but the lens element is shifting across the sensor and utilising the full image circle. You manually focus your first shift shot. On shifting the lens for the next shot you do not touch the focusing ring as the focus remains constant.

Sorry, Peter, but you're incorrect.  A shift-pano with a TS lens, where the camera isn't moved but the front of the lens is shifted relative to the camera, will result in parallax.  Whether or not you can see that in your image depends on the relative distances to and between the subjects in the image.  Old view cameras shifted the camera back with the lens fixed in place - no parallax.  TS lenses used as you describe shift the lens with the camera fixed in place, and that means parallax.  To avoid that, you need to either fix the lens in place for an optimal solution (DIY collar or the expensive Hartblei one), or use a macro rail to move the camera an equal-but-opposite distance as you shift the lens.

It's also worth mentioning that for architecture shots using a shift pano, for example, if 24mm isn't wide enough to capture the full height of a building, negates perspective correction - and that may be the very reason you used a TS lens.  So, to the OP - the primary determinant of 17mm vs. 24mm should be the focal length you need.  A sharper lens (TS-E 24L II) doesn't help if you have to cut off the top and sides of a building.

Personally, I went with the TS-E 24L II as that focal length works best for my style.

D7100 in the mix: -- let's take a quick first look -- the ...--100% pentamirror viewfinder...

Are you sure about that?  Pentamirrors are cheaper (which is why they're used in the Rebel/xxxD line) and dimmer than the preferable pentaprisms.

EOS Bodies - For Stills / Re: 5D mark III auto focus (newb) question!
« on: February 20, 2013, 10:40:09 PM »
Sounds like you want auto AF point selection, which picks the subject closest to the camera.  Press the AF point/mode select button (top right on the back of the camera) then turn the main dial (index finger wheel) to 61-pt auto (the parentheses-like icon, all the way on the right of the top row of icons).

Personally, I prefer to use the joystick to move the AF point where I want it, rather than let the camera pick my subject for me...

PowerShot / Re: Comparable Camera to the Sony RX100
« on: February 20, 2013, 08:37:40 PM »
I picked up the RX100 yesterday and finally had a chance to play with it. Here are my impressions:

IQ is great. Handles low light quite well. My gripe, not necessary Sony's fault, is my difficulty of holding the camera. It's a bit heavy for its size, since it is very well constructed. I have to remind myself from time to time to hold on to the camera tighter and not to drop it. It is a bit slippery since there is only metal facing in the front.  Since I have difficulty holding on to the camera, it was even more difficult trying to push the little buttons in the back in trying to change the settings and take the pictures manually. So it was best for me to just keep the settings on full auto.

It's a good little camera. But I think I'll either return it or give it to my daughter.

You can buy a little grippy thing that makes it less slippery and more comfortable to hold, if you wanted to try that.

Yep. Google "Franiec rx100 grip".

Well...darn, now I need a 12mm extension tube...  ;) If it works the same, that means the 1.4xIII-EF12-2xIII combo behind a 600/4 will give me 1680mm that reports as f/8 and will AF on the 1D X.

Yes, the 100L does a very good job as a portrait lens on FF (a bit long for my taste on APS-C, though, although it's ok outdoors).
