  1. I have exactly the same problem with a Lenovo T61 and original Eye One Display. I was actually going to write up a post about it when I saw yours.

    The default LCD calibration is atrocious -- just horrible to look at, let alone attempt to do any sort of photo editing. Calibrated, the screen looks okay. Unfortunately, in any colour managed software like Photoshop or Lightroom, blues are shifted to purple. Pure blue (0,0,255) is a lovely shade of purple. This is a MAJOR problem for me.

    I fully understand that laptop LCDs are usually pretty lousy, but after calibration, they are generally quite usable for non-critical photo editing. Having blues shift to purple is a crippling defect, since many of my photos include lots of snow. The Firefox 3 betas have the option of colour management, and enabling it makes sites with blue schemes look purple. I'm essentially stuck with either a calibration that is hard to look at, or purple blues. Having the majority of colours accurate at the expense of one major colour being completely inaccurate is not an acceptable solution to me. I have actually been considering buying a completely new laptop. It's extremely troubling to see that a new Macbook Pro has the same problem.

    There have been several threads on photo.net about this issue. It is always the blues shifting to purple. It is not limited to any particular brand of laptop or calibration hardware. The same laptop calibrated with different hardware exhibits the same colour shift. Unfortunately, nobody has ever proposed a solution, so there is simply no way to fix it that I know of. I am surprised that no calibration hardware manufacturer has ever addressed the issue. Another forum member and I sent our monitor profiles to Gretag Macbeth, but I'm not sure anything ever came of it.

  2. I bought an 8GB Extreme III for my 5D. It can't really take advantage of the extra speed, but the card was only $5 more than the Ultra II, and my card reader can use it. Plus, I know I'm likely to be using the card in other cameras I own (like my 40D) or will buy in the future. I'm still using a 4GB Ultra II card in my 40D that was bought in March 2006 for use with the 30D I owned back then. I did consider the Extreme IV or Lexar equivalents, but they weren't really worth the extra money to me.
  3. I've always been annoyed that the cheaper Canon primes are often SO cheap that they feel like toys. When Canon switched to the EF mount, many of the early lenses were released with similar sort of build quality, no USM, etc., and have never been updated. Nikon took a different route and designed even the cheap primes at a higher level of quality, and somewhat higher price point. I'd certainly be happy to pay 40% extra to get a 35/2 of the Nikon build quality. The Nikon 50/1.8 is only $15 more than the Canon toy!

     

    The mk I version of the 50/1.8 is somewhat less crappy, but they have always commanded silly prices on eBay and such, especially if you consider that the MINIMUM age of any sample is over 17 years!

  4. I also took advantage of the Canon Canada double rebate program (5D and 430EX). At $1700, with no new full frame in sight, I couldn't pass it up. I also own a 40D, which will also see lots of use on the tele end, but even the 5D's viewfinder convinced me I'd made a good purchase.

     

    I miss the 40D's large LCD, live view, 6.5fps, etc., but having my lenses work at their proper focal lengths and having a nice big bright viewfinder makes it worth it to me. I don't have any problems with the AF speed or accuracy with respect to to the 40D, and I am extremely pleased with the image quality.

  5. RRS says the BH-40 is suitable for the 70-200/2.8, so I'm sure it would be fine with the 100-400 as well. I use an Arca Swiss ball head for my 100-400, and the tripod mounting itself is rock solid. I actually find it a lot more difficult getting the lens itself stable in the tripod mounting, because the centre of gravity moves so far from the ring at the 400mm setting. Using a battery grip helps quite a bit, but it is still not really adequate compared to most tele lenses.
  6. Slide film just isn't economically feasible here in Canada. We don't have cheap slide mailers, and having a roll developed locally costs about $12. This might go down to $10 in a major city like Toronto. The idea of actually BUYING the film here is a joke, too -- a roll of Velvia 50 costs $12, as opposed to about half that at B&H. For anyone keeping track, that means it would cost $27.34 with tax to buy a roll of Velvia and have it developed here. $20.50 if I tack the roll onto a B&H order.
  7. I just heard back from David Yau by e-mail. In his opinion, the problem is caused by either a faulty release mechanism, or a blockage of the release mechanism. The former would take a few minutes to fix, and the latter an hour or two and cost twice as much. Whatever the cause, he will be able to fix it for me on Monday.
