She doesn't look anywhere near that old.  Maybe it's the hat and glasses?   ;)

Lenses / Re: Best Lenses for Canon EOS 5D Mark III according to DxO
« on: May 16, 2013, 09:44:21 PM »
The only thing more useless than DxOMark's Sensor Overall Score is their Lens Score.

I do find it interesting that they rank the Canon 70-200 II so highly.  When they first tested it, they said it was not quite as good as the MkI version of that lens.  No one else agreed with their assessment, but they stuck to their results.  But looking at it now, on the 5DII they have the MkII scoring a 24, and the MkI scoring a 21 - so now the MkII is better.  They didn't bother to correct their text review, though, where they conclude: "...these 2 lenses are both excellent telephoto lenses, but the overall scores come out slightly in favor of the previous version of the Canon EF 70-200mm f/2.8L IS USM, especially for Travel and Sport photography, which are the main use cases of these telephoto zoom lenses."  Scroll down to the comments on the linked page to see their denial that there's anything wrong with their results - results they now seem to have quietly changed to reach the opposite conclusion.

Sales drive revenue. Revenue drives profit. Profit is a major driver of share price and shareholder value.  Share price and shareholder value determine whether a public company thrives, survives, or fails.

Betamax was better quality than VHS.  VHS sold better. Betamax failed and was abandoned.

On a more DSLR related note, Olympus came out with 4/3 format. It was going to be a worldwide standard. Many things about thier cameras were ahead of what the Canon and Nikon crop bodies offered at the time. They had beter user interface, beter weatherproofing, arguably better sensor performance, and faster autofocusing..... and where is it now? ( 4/3... not micro 4/3 ).  Sales sucked, product not stocked by retail stores, death spiral, gone.

Well, the Olympus E5 got a DxOMark Overall Score of only 56.  That must be why it didn't sell.  ::)

sold and sold, nokia sold their telephones, and now we know whats happens, you and Jrista are so  indoctrinated so you can not keep apart what is discussed, why are no Canon sensor at the top 10 in DXO  ranking and start at 17e place?

Oh, we can tell the difference. But, DxO Scores have no relevance to camera sales.

Yes, we know about Nokia.  So come back after Canon drops to the bottom of the market share rankings.  In the meantime, there's nothing to show that's what is going to happen, nothing to show that Nikon/Sony/et al., are beating Canon where it counts (selling cameras), and thus nothing to show that all this babble about sensors and DR has any meaningful impact on the bottom line - camera sales. 

Fortunately for Canon, their customer base is just a little bit bigger than you and the rest of the minuscule group of DR-obsessed forum jockeys.  ;)

I agree, Canon sensors are to late

Gee, I guess it's a good thing that Canon sells cameras, not just sensors....and they continue to sell more of them than their competition.

you can think what you want, the rest is easy to catch up, speed, AF ergonomic  etc  but not the sensor, and there are the Canon Inc  hopeless bypassed by Sony, Aptina, Panasonic, Toshiba, Omnivision, Renesas, and many more  today
And , bigger companies has fallen than Canon when they are not up to date.

Ahh, yes...the rest is so easy to catch up, and lenses, flashes, etc., too. That must be why Nikon, Sony, et al., are selling so many more dSLRs than Canon.  Oh, wait...they're not.  The thing is, if it was 'so easy' than Canon would have been losing market share ever since their sensors 'fell behind'. But they've been gaining.

Also, it's easy to fall into the trap of thinking that the opposite of better is bad.  The opposite of better is worse, and in the case of Canon's 'not better' sensors, worse is still pretty damn good.

Canon have  lived on a long time  on their name and early cmos  sensor tech since 2004, sorry but this tech is old 2013 which can been seen if you compare to   Nikon, Pentax, Sony =  DXO scores etc  why are no Canon in the DXO list over best sensors at all ?
Do you have any nuanced view at all or whats going on  ?

Who needs a nuanced view?  Every year for which there are sales data and during which Nikon sensors beat Canon sensors on DxOMark, Canon sold more dSLRs.  Nuances aren't helping your case.

EOS Bodies - For Stills / Re: 6D accessories?

I've owned the pro "spider holster" for a couple of years, but have not used it much.  Opinions on it or similar?  The thing I don't like about it, is if there is a heavy lens on the camera, it seems like it's putting a lot of stress on the camera-lens interface, as I walk around...the mass of the lens pulls on the mount.  Maybe it's just in my mind, but it seems like it could stress the mount over time.  This is also true of other types such as "cotton carrier", since the camera is mounted or hung on the carrier via its tripod receptacle...while none of the lens' mass is supported by these types of "wearable camera support" gear.  A solution would be some kind of strap or harness that could wrap tightly around a portion of the back half of the lens...but I guess that's too difficult or costly for these companies to design?

My solution is to use Arca Swiss type plates on body and lenses with tripod collars.  I use Blackrapid straps, with a Kirk 1" clamp on the end, so I can easily connect it to body or lens, or remove it for tripod/monopod use. I shied away from the Spider Holster system because of the need to directly attach to a tripod socket. But then they came out with their Arca Swiss plate, and I picked up a Pro holster (which I wear on a Lowepro belt). It works great, I just move the Spider Arca clamp from body plate to lens plate as needed.

Regarding flashes and accessories: I think I'm interested in small flashgun mounted softboxes, but not sure.  Once they get larger than 6x8 inches, they seem too cumbersome to use while mounted on the camera, without extension brackets, etc.  I've had the "omnibounce", liked it, but I want to try some kind of larger box.

I started with a Lumiquest Softbox III, attached with their Ultra Strap so I didn't have to stick Velcro to the flash. It worked, but was a bit flimsy and the attachment wasn't robust. I now use a Lastolite Ezybox Speedlite - attachment is very robust (a Velcro strap that goes around the back of the flash, instead of a band encircling the head), works great.

I've used my 1D X with a 600/4 II and 2xIII to track birds in flight, sometimes handheld. It does fine.  However, when shooting small birds in thickets (branches in front of and behind subject), where the bare 600 II locks onto the bird easily, with the 2x it hunts a bit - in that situation, it behaves a lot like the bare 100-400L.

Well it's good to see it's not just me.
CPS acted like they never heard of this happening.

Yeah, you're always the first one...then there's a firmware update just for you.  ::)

Shouldn't really be necessary though ideally. Also I believe the recommended testing distance is 50x the focal length if possible?

Never used Reikan Focal. Can anyone tell me how much it is to buy and how difficult it is to use? How does it work? Think I should give it a try.

Does the fact that I can get reasonably sharp results via Live View mean the inaccuracy is down to my camera and not due to any fault with my lenses?

Manufacturing tolerances for bodies and lenses make it necessary. Every hear of Canon Professional Services (CPS)?  One of the main reasons CPS was started was for pros to send their set of bodies/lenses in for focus calibration.  AFMA puts one way to do that into our hands.  It's not usually noticed with wide/normal/short tele consumer lenses - the narrow apertures mean a deep DoF that masks focus errors.  But with fast lenses, and long lenses with close subjects, the thin DoF (especially on FF) means small focus errors are easy to see.

FoCal is great.  http://www.reikan.co.uk/focalweb/  Some tips are print the target with an ink jet (not laser) printer, have a good tripod on a stable surface, and lots of light (>10 EV reported by the test, and be sure it's sun or tungsten/halogen, not standard fluorescent or AC-powered LED lighting).

Could be body and lenses, each combo can be unique.  AFMA lets you adjust for each lens (and multiple copies of the same lens, with current bodies).

I am looking for the 300mm 2.8 L II lens. But instead of getting chepaer, the price rises and rises...

Yeah! Canon, milk us

Must be an EU thing. In the US, it's flat and cheaper than at launch (the increase at the left side was before launch when they raised prices relative to what was announced as expected retail pricing).

1.) Why did Canon raise the price of other lenses too? 500,600,800...  are about 500-800$ more expensive overnight.

2.) Are there alternatives for the 500,... lenses? Sigma?
Half of the price. How good are they?

1.) Not as far as I can tell. The 300 - 600 II lenses haven't seen a price change in several weeks, and they're a couple to a few hundred cheaper than at launch.  They did all see a big increase in between announcement and launch - but that was a 12-18 month interval, and IIRC there were currency issues then.

2.) The Sigma 120-300/2.8 is reportedly very good, although not quite the IQ of the 300 II. But longer offerings from 3rd parties don't come close to the Canon supertele lenses.
