I know this has been done to death, and yes I have used the forum search option before posting, but haven't found anything that specifically answers my questions!
I'm trying to decide what long lens to go for, I've got a Sigma 100-300mm f4 which I am in the process of selling and am looking to upgrade. I shoot quite a bit of aviation as well as a bit of nature (birds and badgers!)
The choices I have come up with are:-
Canon 300mm F4 L
Sigma 120-300mm F2.8
Now, with regards to the Canon my first question would be 'is' or not 'is'?
IS would come in handy for prop aircraft and would help somewhat with my panning, however they cost twice the price of the non-is version. I shoot quite a bit of the wildlife stuff using a tripod or monopod. But I'm sure there will be times that I need to shoot hand held.
Also I read somewhere that the non-is version of the 2.8 is no longer supported by Canon and as such would be nigh on impossible to repair - does this apply to the F4 version too?
Onto the Sigma, no IS for a start - but it is faster and gives the flexibility of a zoom. However there are all sorts of stories about poor quality copies of just about all sigma lenses. Also just how sharp is this lens at 300mm wide open?
Anyone who has experience or just an opinion please voice it!!
Basically it boils down to the fact that I have around £1k to spend and want top quality!! How would you invest it??
(body it will be on is a canon 7d)
Over to you!!
Regards
Neil
