A camera or lens?

Hey all... i wanted to ask you guys on a new camera or lens purchase.

At the moment i use a 1D Mark IV with:

Canon 50mm f1.8
Canon 70-300mm
Sigma 12-24mm f4
Sigma 24-70mm f2.8
Sigma 70-200mm f2.8

Now my brother is at Thailand now and a 5D Mark II cost £1200 brand new and as i never had a full frame i always wanted a camera

On other hand i could go for the CANON EF 8–15MM F/4L FISHEYE USM as i never had a fish eye either.

question is i don't know what i should go for a lens or another body?

please advice

what do you shoot?

Heavy metal concerts and festival along with travel photos

In my opinion, you have got one of the best camera body's but have mwahh lenses. I would look which lens you like the most on your current kit and switch to a Canon L lens. A 70-200L from Canon does have much better IQ. More contrast better colors and probably sharper than your Sigma 70-200.

Maybe you could sell your 1DIV for a 5DII or 5DIII if you want to go FF and use your cash for some nice lenses.

I have been borrowing a 1d4 for the last week or so from CPS and I'm happier with the overall IQ from my 5d2 and 5d3. And the 5d3 to me has a better performing AF, even in crappy light. Right now you could probably trade the 1d4 for a new 5d3 and maybe get some cash out of the deal... Then have fun with whatever lenses you add to it

Without question in your position I'd be sorting out the glassware. You've got a real muddle of lenses.

I myself would get myself an L lens..

I'd be looking for more/better glass if I had a 1DmkIV also.

If you are happy with your current lenses IQ, you don't need to change them for L.. Also i think that wasn't your original question... I really don't understand why always when somebody ask a question like this, and if he doesn't use L lenses always the answers are, change your current lenses..

OP wasn't asking if his lenses are so so or not..

So your question was a 5d2 or 8-15 I would say, why not think about what you want more? If you have always wanted a FF and go with the 8-15, the initial WANT will be there.. So, why not get that FF so you can try all the lenses on a FF also. And maybe later add the 8-15 ?

As the owner of the Fisheye, I have to say that it is a very specialty lens....
Yes it is great, but I don't use it a heck of a lot...

Just my 2 Cents
