I have a Nikon D70. I found out that the transition from film to digital is not always so simple. My lenses that used to work great on film started to seem to have soft focus on a digital camera. Shortly after I noticed this, Shutterbug magazine ran an article about this same subject. Seems as though many "film" lenses will allow light to reflect between the image pick up device and the rear elements of the lens, producing a soft focus look. It seems to be much more noticable on telephoto lenses. The "cure" is to use telephoto film lenses at small aperatures. (Which can cause another set of problems). "Digital Optimized" lenses have additional coating on the rear lens elements to limit this reflection. Beyond that the D70 produces amazing images. And so do comparable Canon Cameras. I do not use a tripod or monopod when shooting motorcycles on the track, but I have always felt I had a very steady hand and can maintain a pan very well on a moving motorcycle or car. The rule of thumb when using telephoto lenses has always been, if you are using a 400mm lens, use at least 1/400th shutter speed. When using telephoto lenses on some digital cameras, remember to bump that by 1 1/2 because of the field of view multiplication factor due to the size of the image device in many digital cameras is smaller than the area of 35mm film.
I only shoot in the fine/large mode in .jpg. I have not tried the Raw format. It is my understanding that Raw is better if you are going to do a lot of work in Photoshop with your images. A lens protector lens is always a good idea. Sorta like wearing your sportbike gear. Sometimes you may find a polarizing lens to be helpful.
And like motorcycles, seat time helps. So get a lot of memory and start shooting.
Don't confuse me with facts, my mind is already made up.
