I have just won a Sigma AF 135-400mm F4.5-5.6 APO lens on ebay as I wanted a telephoto lens for when I shoot motorsports. It sold for £200 however I could have bought a TAMRON AF 70-300mm f4-5.6 Di LD Macro for £90! Can anyone tell me if me paying the extra £110 will be justified and will I notice a big difference with the extra 100mm reach. I’m worried I may have made the wrong purchase.
Yes, you will notice a difference, particularly if shooting from behind a fence. the larger the zoom, the less the fence will be visible. I use a sigma 150-500mm and was at the Aus GP this year. The 500mm photos are much better than the 300mm ones. can i upload photos here?
