Thinking of getting a lens for long reach for some wildlife shots, money is limited so I have looked at the following two
(1) Tamron 200 - 500 f5-6.3 SP AF DI
(2) Sigma 150-500 f5-6.3 APO DG OS HSM
Has anyone used or tried the above any opinons welcome, have researched both but no to sure on which might be best both have good points and bad Tamron slow focus but have extra ring for filters Sigma faster focus but feel it might be softer at full 500 end
