I figured I'd post this up in here, hoping some of you have been in the same situation. I would rather spend around $1500, but $2000 is my max. Right now I am shooting with a 30D that I purchased new several years ago, and the shutter is about to go on it. In fact, just in 45 degree weather last weekend.....it would barely take a picture. I literally had to rub it against me to generate some heat in it for it to work. I'll be sending it to Canon for servicing once I select and purchase another body.
I shoot alot of action stuff. From MX to drag racing, from RC cars to wakeboarding. I also do alot of car/portrait stuff, and even dwindle into landscaping types of shots (scenery). ISO performance is something I am lacking with the 30D, so a pro-level body would do me good. Even though some of the consumer level bodies have much better ISO performance than this older 30D, I do know that.
Several people have mentioned I should go for the 1DmkII. I have also considered the 7D as well. Does anyone have any recommendations? If I do decide to go with the 1D, it will obviously be used. What should I limit actuations to when shopping for a used pro-level DSLR?
When I send the 30D off for repairs, I will request an actuation count. I am going to go out on a limb and guess that I might be in contention for highest shutter actuations on a factory shutter.
