update on lightroom corruption

Since I started noticing the corruption of images in lightroom I stopped purging my CF card. Normally, once I had the images on the raid, and had taken a quick spin through them to make sure it was all there, I would purge the CF card back to empty. But that stopped it pretty quick. Recently I sat down to figure out how many were bad. A quick md5 comparison found nearly 1% of the raws (6 out of 596) that I had shot since moving to LR as my import mechanism were corrupted. This included 2 that I had not noticed the corruption visually in the thumbnails! That last bit kills me... I had honestly hoped the md5 check would have come back and confirmed that I had caught all of them visually in LR.

Not sure how I'm going to deal with this for the 5D2, since I'm currently converting to DNG on import to save space. Need to look into just how much space I'm saving... it might not be worth it.

5D mk II - first thoughts

So I've finally upgraded from a 20D to a 5D mkII. It's quite the jump. :) And also involved upgrading to all new glass for 2/3 of my favorite lenses, since they were EF-S. I've got about 50 clicks on it so far, almost 50/50 split between before/after thumbing through the manual. :) I wanted to capture some thoughts here on my impression of the differences, first the bad.

1. The shutter release. ick. I really don't like it. The 20D has a nice tactile feel and a difference in resistance when you pass the 1/2 depressed mark, and there is an audible click/pop sound. The 5D2 has no tactile response that I can tell, and no audible response. Overall it feels like shooting with thick wool gloves over that finger.

2. Weight. A lot of this is the glass, there's just more of it. But even the body alone is substantially heavier than it looks. I use a hand strap, not a neckstrap for my camera, and have hiked around for hours with the 20D in hand. Not sure I'll be doing that with the 5D2 so much. IIRC the 20D's inner frame was titanium... is the 5D2's steel?

3. CF door. Everything on the 5D2 feels solid, rugged, virtually indestructible. Except the CF door. It's pretty light and flimsy... I fear a quick CF change in the field could lead to it breaking.

4. information overload. There's a lot of complexity in the dozens of different ways to get information out of the camera. I stumbled into screens that looked awesome.. like the back panel showing the full data of the top display with all the settings. I have no idea how, and I can't find anything in the manual to help me get back there.

And now the good:

1. the rear LCD. OMGWTFBBQ?! is that how far we've come with LCD screens in that short of a time? WOW. it's beautiful.

2. operation noise. It's a lot quieter than the 20D... especially the mirror action. I just wish there was a volume control for the blasted focus bleep. I might have to go back to my olde solution of a small square of gaffer's tape over the speaker. Except that it's used for video playback too. Hmm. Guess I go with no beep and learn to rely on the green light in the VF.

3. I thought I would hate live view. And it's quite likely I will. But the ability to do a 10x zoom on it and focus manually.... that has some serious potential. I used to always zoom the lens in, focus, then zoom out to recompose. The problem is that the zooming out has negatively influenced the focus in the past. I don't know if these new lenses will have that issue or not, but that provides a chance to skip it entirely.

4. information overload. There's a lot of complexity to master, and the 5D2 seems to give much more access to the raw data to work from. I just need to learn how to process it in my head.

oh, and some other observations...

1. damn I need more and faster CF. (ordered)

2. I shoulda moved up to L glass a long time ago. :)

3. damn I'm going to need more raid array. (bah... firs step is DNGs, second step is blowing away some olde crap on my current raid array... I reckon half of it is candidate for a move to /dev/null)
