That is true. Shooting digital makes everything a lot easier, the only problem I see is that some people do not know the difference between quality and quantity. I visit several photoforums, and some people post 30 picsor more from an event or happening, while only 5 are really good. The others are not bad, but just normal pics, not special ones.
Yes, it is nice to have the best equipment, but I doubt that I will make better pics with a fully professional camera than my semi-professional. I'm not that good to see the difference. At least I'm glad you bought a good lens since that is the most important part of makeing a picture, some people buy an expensive camera, but a crappy lens, that won't give you perfect pictures under hard conditions.
Did you also buy a UV filter to protect your lens? You can just srew it on the lens, does not effect your pictures, but if something goes wrong you will scratch the filter, not the first element of the lens. just screwing a new filter on the lens is cheaper than replacing the front element of it. But same with filter, if you have a professional lens, do not budget on the filter. My B&W UV filter cost me 70 euros, but that is because the lens had a 82 mm wide, the other lens I have is 77 mm wide and then the filter cost me 50 euro.
btw, I have:
Canon 20D + Sigma 24-70/2.8 + Sigma 70-200/2.8 + Sigma 1.4x converter.
I wish I had the money to buy the original Canon lenses in these ranges, but those cost 1200 euros each. Sigma is a little bit less quality, but only half the price
Tomorrow will be my first Ferrari-meeting with this camera, I will post some pics
