Thank you guys for the replys
I feel I should clarify about me falling down the stairs and hitting my head before I go any further. It has really nothing to do with why I am downgrading my equipment, it was my vague attempt to open with a joke on why I am taking this path rather than upgrading my gear. It was an accident not related to photography at all, and it doesn't really belong in this post. I apologize, my sense of humar is rather, special. But I'm fine now, tank you for your concern.
I realise I was unclear in my original post as to why I am doing this. The short answer is cost. I will try to clarify a little further.
I can't justiify to myself owning all this expensive gear when I only use it for what it's worth 1-3 times a year. It is great having one of the best camera bodies and some of the finest glass available at my disposal, but I know I don't really need it for what I am shooting, so I am looking to get by with cheaper equipment.
Size and weight has never been an issue for me, so I am definetly staying with the DSLR platform.
As one of the most significant things I shoot is for a local music festival I was thinking to concentrate my new, cheaper collection, around this. I have sort of already decided on a 1D Mark III, so that part is alright. But I am not sure about which lenses to get. I do want low light capability, so primes are my first thought. I have never really used prmes before except for my 50mm nifty-fifty. I am mainly looking for advice regarding the more affordable Canon primes, not excluding the 135mm f/2L as it is not too expensive to buy used. But the likes of 24 1.4, 35 1.4, 50 1.2, 85 1.2 etc are all out of the question due to price.
I know that for concerts I want something wide, and I want something for tighter shots close or equal to 200mm on full frame (135mm f/2L with 1D3?). I am thinking of keeping the 24-105 so I have at least one lens that is weather sealed. But other then that I am pretty clueless on which of the Canon non-L lenses to aim for.
I hope I managed to elaborate a bit better on what my goal is.
Again, thank you for your help.
