View Full Version : Spinning Main Dial Really Fast

Hey guys... I have a 30D and always wondered...
Is there any harm to spinning the main dial (the one on top next to LCD) really fast? Like spinning it to make quick adjustments? It obviously feels notched, so there is some sort of gearing... but what do you guys think?
Am I hurting the main dial when I spin it real quick? Should I go easy on it (one notch at a time)?

I'm a "quick spinner," too. I've had a few film SLR bodies with the wheel, going back to 1994, plus the 30D----I've yet to have a problem.

The notches are detents so you can feel single increment changes. The wheel it self is just an electical position sensor pickup and so little to worry about with speed.

Nope, no issues. I've spun the QC dial on all my cameras pretty fast and never had any problems.

only thing maybe with quick spinning is the heat created with friction wearing down the notches. ?
as opposed to slower spinning thus not creating heat, albeit minimal i would suspect.
i'm a fairly quick spinner myself ;)

Mine's been rolled fast mostly every time I take it out for the past 2 years and it's still going strong :)

I don't think I know how to spin slow...

my finger doesnt know the meaning of spinning a dial slow just like my foot doesnt know the meaning of lightening up

I think you overestimate your sustained power delivery. You would have to spin mighty fast and mightly long to generate any kind of significant heat in the detent mechanism.

I'm going to go to the hobby store and see if I can find some similar sized detented wheels and mocking the sensor assemby for the main dial. I'll be able to run some tests at various spinning speeds and use my laser heat caliper that I have to gauge how much potential for damage can result from moderate to fast spinning. If I make an excel spreadsheet with the data, would anyone be interested in seeing the results? Just let me know and I'll post it for ya.

Sounds good, but will you use a filter? :lol:
