So, I'll give you a bit of background about me before I give my advice that I give everyone who asks... what camera should I get?
I am the owner and CEO of Big Ten Photo... Yes, the Big Ten Conference.
www.BigTenPhoto.com
We provide team photographers for all of the Big Ten Universities, cover all of the B1G Tournaments, and provide Team photographers for most NCAA events including many non Big Ten Teams.
Little schools you may have heard of. USC, LSU, Florida, Oregon, Texas... just to name a few. On average not including myself and staff, We hire anywhere from 40-70 additional photographers through out the year.
So... To answer the tougher question that it sounds as to what camera you should get... I always tell people a very simple answer... Find a good camera cheap on eBay... Right now, Canon's 1Dx is going for around $3,000...
The Mark IV is going very cheap...$1500 or so, The Mark III even cheaper, I just saw one for $300? Usually these cameras are very well kept as well as very well used. They are built to be used hard... You will get way more bang for you dollar doing this. Worst case scenario you get a body with a blown shutter... The most I've ever spent on replacing a shutter was $400. With a new shutter, the camera is virtually brand new.
As for lens... Well I can't talk enough about the need for good glass. That being said, you probably aren't looking to spend that kind of cash... There are a ton of alternatives to expensive glass out there. Just figure out what exactly you are looking to shoot. Canon and Nikon make mid level glass for just about every range. Generally speaking Prime (NON-ZOOM) Glass is always better than zoom. That being said, there is always use for a couple of good zoom lenses in the bag.
When I'm out, not working, I usually have a 14mm,24-70, and a 70-200. With all of that said... I also still carry a Holga Medium format camera as well... Just for fun. very cheap, plastic everything... But fun to play with.
