Oh yeah it ' s definitely not the same density as the East coast . But that ' s the whole reason why the west is how it is . Just people freaking out is all <| sep |> The term organic is really just about branding anyway , as I see it . It ' s a restricted term that can only be applied to certain products , and it will always appeal to a certain segment of the population . Whether or not it actually means anything is irrelevant . Some people buy organic stuff for no other reason than that it ' s organic . <| sep |> I like it . It feels very solid and the results so far are nice and sharp much sharper than the tokina 1116 mm 2 . 8 I was using previously which didn ' t really work below about 15 mm after I went full frame with the 5 D . This pretty much completes my Tamron zoom set already having the 2470 mm 2 . 8 , 70200 mm 2 . 8 and 150600 mm . Not many complaints all round and saved a fortune getting most of it second hand .
