Hi team, Quite desperately need to upgrade my gear. Bit of background - I shoot predominately equestrian sports and I've found over the last year I seem to be deleting a lot more photos than I use to! Not sure if this is a lens or a body issue and both are fairly old. I shoot with a Nikon D7000 (which I must have purchased about 5 years ago) and a 75 - 300 VR which I purchased 2nd hand (with minimal use) about 2 years ago. So my question. Do I upgrade my lens and get a 3rd party (due to half the price) Sigma or Tamron 70 - 200 f2.8 ? Do I upgrade lens and get Nikon 70 - 200/2.8 (Or another lens for horses! throw suggestions at me! I really want to achieve that blown out background more!) Do I upgrade body and if so then what?! Full frame or crop etc! I was originally thinking the D750 but it doesn't seem like much of a sports body.
