I do fashion and glamour photography.
I do at least 45 girls a month.
Averaging 400-500 Photos per girl...
That's 270,000 per year.
The 1D X has a life of 400K.
So I should be replacing the shutter in about 2 years.
My old 1D IV had 270,000 on it after 2 years of use. I had Canon replace the shutter for only $250 at a CPS Gold discounted price.
Not bad for basically getting a brand new camera.
Don't be afraid to shoot.
