The non-photographers might want to skip this blog post as it is a fairly detailed Tamron 70-180 v Canon 70-200 lens review for Sony E-mount cameras. There have been lots of reviews comparing the new Tamron 70-180mm f/2.8 Di III VXD (A056) against the Sony FE 70-200mm F2.8 GM OSS (SEL70200GM) and Sony FE 70-200mm F4 G OSS (SEL70200G) zoom lenses. These reviews are great, but I feel there’s a bit of gap as they assume you already have one of the big white Sony zoom lenses. I know many people that have switched to Sony over the last few years from Canon who have held onto some of their Canon lenses to use with an adapter. With the Sony 70-200 f2.8 currently costing £2149.00 quite a few I know have held onto their Canon 70-200 f2.8 lens, put off by the huge cost of the Sony equivalent. This was definitely the case for me.
