[quote user="Roland Scheiner"]1.) The camera only can take images when the AF has achieved focus although you press the shutter button straight down.[/quote] If you use the enable the AF-ON button, then it will take a picture every time the shutter button is pushed, even if the AF has not achieved focus. That is how I use my 5D2. It only takes

Anything that doesn't require phantom power and puts out a sufficiently strong signal (i.e. condensor, not dynamic) will work. I use the Rode VideoMic. The Sennheiser MKE 400 is smaller and works well. That will be better than the on-camera sound, but unfortunately you'll never get good sound because of the automatic gain control on the Canon

Nice concept but poor execution. One of my favorite videos in a similar vein is "Chimping Exposed" .

[quote user="BCalkins"]One thing I often wonder is if you are better to gain a shutter speed and underexpose to get more sharpness (at the expense of noise), or likewise go up an ISO stop. What is sharper looking in a print - faster shutter and higher ISO, or lower shutter speed/lower ISO?[/quote] I always choose fast shutter+high ISO over

It depends. Overall I'd say Xti with L lenses, but there are some cases where the 50D+28-135 will be superior, e.g. stopped down, large prints, with heavy post processing. The Xti+L will be better in most cases, such as faster f-numbers, normal print sizes, and less post processing. But again, those are just generalizations.

[quote user="Jon Ruyle"]I don't know how af works, but isn't it the DOF that matters, and not the f/ number? [/quote] The reason I specified the f-number was because the most accurate AF sensors are the f/2.8 sensors. Most of the time we use the f/5.6 sensors, which are not nearly as accurate, but I wanted to discuss the best case

First of all: do you shoot raw or JPEG? If you shoot JPEG, then the 1D IV is a no-brainer. The processing has improved a lot, particularly in noise reduction (though it's still far behind what you can do with raw). If you shoot raw, then the choice is a little more nuanced. First of all, you stated that the 70-200 f/2.8 meets 80% of your needs,

[quote user="Johnny Rasmussen"]I prefer The Imaging Resource for technical analysis. Do you think their methods are better?[/quote] Yes.

[quote user="Johnny Rasmussen"] I have been going through the reviews at dpreview, looking at the DR for most of Canon´s DSLR´s. [/quote] Let me stop you right there. DPR's section on "dynamic range" is based entirely on JPEG with default settings. It has nothing to do with the actually dynamic range of the raw files

I think the reason why DPP is turning out soft 7D files is because of a manufacturing defect: in each GRGB group of pixels, the gain and offset between the two green pixels is slightly mismatched, from 1% to 3%. This is enough to cause mazing artifacts in the demosaic algorithm. The way Canon is correcting it is probably to average the green pixel values
