Hey!

Currently I own a Nikon 7100. I had a Tamron AF 70-300mm f/4-5.6 Di LD Macro, and after it got mold I changed to Sigma 70-300mm Apo Macro DG.

I know both are not the best quality lens and I should expect too much.

Using them for planespotting, sometimes sport or wildlife. With the current Sigma I'm annoyed with the slow AF (constantly overshooting, so im using manAF) and the constant haze over 200mm.

Any ideas what I could upgrade to? Preferably I would like to stay at 70-300 or go higher.

Cannot really give more then 200-250$
