Hi,
I started with my photography experience with the 350D/rebel 11/2 years ago with the kit lens, now previously i had canon point and shoot film cameras for holidays and stuff and could could take it or leave it.
My husband and I decided to buy the 350D cos we had the spare cash rattling about and it had the kit lens. Because the images were so much better to start with it inspired me to use it more,, that made me get better and I really started to understand the camera more. I know we are not discussing whether a beginner should buy a Pand S before a good camera ... so its not quite on topic.
I blame digital and the fast learning curve you get from it as the reason i came to love taking pictures so much and why i had to empty my bank account to buy the 5D.
It was actually having the 60mm prime and 'needing' a replacment prime for my 5D ( thats what i told my husband) that made me realise that i was going to love the 135L and I wasn't wrong. (I am agreeing with you again!) Still loads of room for improvemnt though which is the most fun part. and what i find amazing is that I was able to sell my 60mm, 10-22 and rebel for 70-90% of what I paid for it. So its not like buying high fashion you can sell the stuff it doesn't work out (thats what i tell my husband), maybe think of it like rental!
anyway back on topic .. I think using the kit zoom lens is the most useful, if you get a prime you can't experiment with different focal lengths. I do agree that a prime 50mm is a good choice so add that to the kit bag.
It was not until I got my 60mm prime that i had to start thinking hard about the composition, not just sitting on my behind pressing the zoom in and out. That was really useful
I have been in forum asking for advise about what lens i should go for and the advise has been useful, very frank most importantly..made me think about stuff. Some people advised me to try rental which was great advice..
as i got to try the 14mm canon 2000 dollar lens over a weekend at death valley, now that was too rich for my blood but a lot of fun for 80 dollars. it confirmed that I would like a wide prime or the 17-40 for my 5D next as I really enjoyed the wide angle and it gave me my best picture of the weekend.. (14mm too wide for me on balance).
I feel I am still a beginner AND I am spending a lot of money on lenses, but so far I think i have made the right choices with the help of the forums ...only regret was buying the 10-22, most people help you think carefully about choices which is why i love this site.
and I will not buy a crappy lens just cos i haven't got years of experience under my belt.
on the whole i agree though.. as i did start with just the kit lens for 10 months, later choices were well considered and with the help of the forum.
