I picked up my Canon 5D at one o'clock today. I brought my Carl Zeiss 50mm 1.4 ZE with me. I wasn't able to really take her out to see what she has... but I did shoot my desk at work. One thing you should know... My office is very very dark. In fact, we call it the Bat Cave. The below image was taken without a flash or tripod. Take a look at the camera data.
The photo isn't a great one by any means. But it shows well how far well it could shoot in low light situations. Keep tuned to far better photography from my 50D. And for the final shots taken with my Canon 30D.. Will I resurrect it in the future? Muah ha ha ha haaaaaaaa. (That's an evil laugh with my picky up to my lips.)
