Today, equipment bought in Europe are covered by the warranty here, but not the US bought items. Hence, the risk has gotten higher, since you now have to ship the equipment to the U.S. if anything goes astray.

So if I live in Norway, take my camera with me to Los Angeles for a four week holiday and have an issue with it early on in the trip, I can't have it repaired under warranty at Canon service center in Irvine, California? (Irvine is part of the greater Los Angeles metropolitan area.) If so then that sucks. Rinse and repeat if I change the country in which I live within the warranty period of newly purchased Canon equipment.

Not sure if it goes that way. If you bought it in Norway, I am not sure what kind of warranty you would be covered under during your holiday. It is rather that for equipment bought in the US taken back to Norway that are not covered in Europe anymore (a thing they implemented two years ago to stop people from buying in the US).

I am really not sure. I know it was implemented to prevent us from buying in the US, but if you are a resident....?

Technical Support / Re: Color Space: sRGB vs AdobeRGB

« on: October 20, 2012, 05:17:25 AM »

When you have (for example) a JPEG file, each pixel is characterised by 'red', 'green' and 'blue' numbers.

The colour-space defines how these numbers map to an actual colour - it is what allows you to determine that { 90, 90, 10 } represents a particular shade of 'burnt-yellow', for example. sRGB and AdobeRGB are just different ways of mapping those numbers to actual colours. AdobeRGB is a mapping that can encompassed a much broader range of colours - including colours that can not be represented in sRGB at all.

Every method you have for displaying your images will have some limitations on the colour space. For example, a printer may be limited by the ink colours that it has, and a monitor by the particular characteristics of its phosphor or LCD filters.

Generally, it is easier to display sRGB images - partly because the smaller range of colours means that more output format can show the image as you intended, and partly because for historical reasons sRGB is widely used. However, some output formats (or image processing software) may be able to use a broader range of colours than sRGB can represented - in which case using AdobeRGB is a better bet.

Note that if you shoot in RAW, the CR2 files have a colour space that is defined by the colour-filter array on the camera sensor - the broadest colour space possible, but specific to any given make/model of camera. However, when you process the RAW files you can choose to re-map this to sRGB, AdobeRGB or any other space that you choose.

Interesting. I always shoot in Raw exclusively on my 5D II and 1Ds III (are there differrences on these two sensors in what type of color they can receive in Raw on the sensor?). My main question is this: Would it not make sense to always shoot in AdobeRGB? As I understand it, you can always change the colorspace in post-processing in program such as CS or Lightroom, thus giving you the best, and enabling you to use it the way you want, as opposed to the opposite where you shoot in sRGB because you wanted to produce for web, and then find out that you would like to do more with the picture (apart from the extra space the AdobeRGB takes, which is not relevant for me)?

I find it interesting to read this thread. I live in Norway, and like most europeans know, the U.S. and Canadian prices are very low compared to the rest of the world, Japan included. B&H, Adorama and others have priced several of their Canon products the last few years so cheaply that running a camerastore in other parts of the world becomes very hard. It's a known fact that for the most high end products from Canon, a person can order a round trip with hotel to New York, buy the stuff you wanted and still have saved money. An example: Last Christmas B&H had an offer for the 17mm TS F4.0L to a price of 12.500 NOK, while in Norway the same lens costs 21.500 NOK (3795 usd today currency exchange). A roundtrip from Oslo - NY cost about 4400, and plus cheap lodging you have saved money, had weekend in NY, and that is just one of the lenses. The only risk you run is that the customs in Norway may force you to produce proof that this lens was bought in Norway previous to your trip. If caught, you need to pay taxes that equals the price of Norway. Until two years ago the US warranty was also valid for Norway. Not so anymore. Today, equipment bought in Europe are covered by the warranty here, but not the US bought items. Hence, the risk has gotten higher, since you now have to ship the equipment to the U.S. if anything goes astray.

EOS Bodies - For Stills / Re: Full Frame Sharper Than Crop?

« on: October 19, 2012, 05:11:50 PM »

I suspect it may simply come down to the size of the photosites on a crop sensor. They tend to be smaller than those on full-frame sensor and thus the laws of physics and diffraction come in to play sooner on a crop sensor.

For a fuller and more in-depth answer just hang on, I see our friend Neuro on the horizon with his usual top-notch explanations for the witchcraft that is optical physics.

Pah! Just as I type this, there he comes!

I have a question also. Diffraction. I have read about it, and there are several places that warns against closing the lens too much (some say you should not go to F22, but stay at F16 due to diffraction. Does anyone have a practical example on how this would alter a picture, besides a theoretical argument? Otherwise, when shooting landscape for instance, why would one not go minimum aperture all the time, given that you control the other factors?

I need a zoom lens that covers that range.   (Plus I'd like circular fisheye on the wide end.)
Very cool, thanks.

Thanks. I just told a friend the other day that my dream walkaround lens should be 14-500 F2.8L IS II USM, and that the weight should not exeed the 70-200 II, and the price should not be higher than the latter lens, lol

I know that view, from Akershus Festning  you from Norway?

Yes from Oslo, Norway. It's not from Akershus Festning, but higher up (right above Sjømansskolen on Ekeberg:)

Lenses / Canon 800mm F5.6L IS USM experiment

« on: October 13, 2012, 04:03:55 PM »

I am lucky enough to borrow the 800mm this weekend. I wanted to see how far it reaches, and also how far it reaches with help. The series are from 16mm to 2560 in effective focal lenght. The last picture is cropped a 100%. The distance from where I was standing and the building over the Oslofjord is approximately 9 kilometres.

EOS Bodies - For Stills / Re: Ideal choice for second body?

« on: October 06, 2012, 02:55:47 AM »

1D mk III, isn't that the one with a APS-H sensor and 8 frames per second? Do you need speed in a wedding? and do you need the crop for anything that a 70-200 cannot cover? Given your list, I would actually opt for a used 1Ds MK III. It is an awsome camera, and was the flagship camera for full frame until the 1Dx was released.

Software & Accessories / Re: Need help on neck/Shoulder Strap for camera body...!!!

« on: October 05, 2012, 10:33:41 AM »

I have now had the chance to test out my two new Black Rapid RS 7. I have to say I have mixed feelings here... I did a shoot where I had them both on in a cross with two cameras and lenses attached. It worked fine. Why the mixed feelings? It feels a little plastic, and the other day I was using one of them with a 1Ds III with a 200 F2.0L, and it made a continous squaking noise, that made me fear that it could actually brake because of the weight. Second, it slips down again after I have raised the straps (to have it in hip height) and that's a bit annoying. I think I will actually test out the Sun Sniper straps (more expensive, but seems more solid (in addition to having the steel wire inside).

Since you are renting and you don't have the pressure of being the first shooter, why not also have some fun while testing the gear? I would rent three lenses and not two... 24-105L, the 70-200L IS II, and the 85L II
