I once ran into someone who bought a 7D + 85mm f/1.2 L + 580EX II as his FIRST ever kit. He had absolutely no idea what he was doing and took a lot of stuff that more experienced photog's could take with an iPhone.
I would only go as far as saying the equipment should match the skill level of the user. Both are equally important.
I agree both are important:
But unless this guy took a loan out from his kid's college fund, I find nothing wrong in his choice or his purchase. Looks like he did his research, zoned in on a prime lens (most noobs like me would try and get max coverage from 15mm to 400mmm regardless of the speed of the lenses...) that is fast and sharp.
Why should he be asked to buy a rebel kit lens when all of us would not... The only wrong thing I can see is if he thinks he can shoot like an Art or Ansel or any great guys on this forum without learning how to shoot.
I gave my 350d and kit lens to my 12 year old daughter trying to get her into this wonderful hobby... She might take 100 pics and have 10 turn out really great... but the limitations of the kit lens then comes into play... if she had better gear, those could have been even better....
I just got my first L lens a month ago... my skills are still the same as a month ago, but my successful rate has gone up significantly. For example: Pictures with L lens dont burn out highlights as much as kit lens do, I don't know why but no one told me this would be one reason to get an L lens...
I am not saying gear is more important than skills, but gear WILL make a difference, so kudos to that guy to get decent gear.
