Was looking at lens in a shop that doesnt sell indian food despite the name,the sales chaps idea of selling me a lens was to slag off tamron repeatedly,to jab a biro into the lens, and the d300 camera i was also looking at,to come out with techinical terms like colour washout,at the edges, and that tamron was only suitable for people who didnt care about photography, but just took pictures of machinery,(like i do, steam trains etc)the classic was tamron lens where made of plastic and poor qulity glass
He then told me i needed a dedicated 39 quid sd car for a basic video camera, as tghats what it said on the sd card, video sd card.
Oh ive got a sigma 70 to 200 zoom,on a nikon d40, nice lens and got a free filter from the nice helpful chap in Jessops,just for asking.
