Opps sorry, I didn’t spot the mention of a Sony DSLR in the initial thread, it slipped under the radar from the lack of capitals when I was scanning over the text!
No suggestions from me I’m afraid, not familiar with Sony DSLR. What are Sony DSLR like? How do they compare from your experiences with them?
Could you be convinced to buy the Canon 70-200mm f2.8 L IS USM? It’s probably THE most credited zoom lens out there, tried and tested and highly recommended.
There’s a sigma equivalent, and I use it for sports shots on a Canon body, but it’s light enough that it wouldn’t be awkward on a Sony DSLR.
I havent looked at the Sony alphas for a while, but if they’re followed on from the Minolta’s physically they’d be smaller than their canon counterparts. But the Sony body tends to be heavier due to the in-built opticial stabilzation – makes lens buying a lot cheaper when going for the 3rd party solutions, you don’t need to pick the IS/OS versions. Which is good, because the minolta w/OS in the body, and a standard lens is half the weight of a canon with an IS lens.
