I'm worried by the quality of the Tamron 70-300mm lens but would it still be a step up from my Fujifilm s8000fd?
Any thoughts purely on the quality of images/features of the camera? (especially in comparison to my existing camera)
(I still realise I need to go into the shop to try them out but I'm worried if they only have one of my options in stock I might get over excited and plump for the first one I see and regret it later :bonk
I'm never going to be able to spend much at all on future lenses

so it will always be photography on the cheap. If this could be kept in mind before recommending £500+ lenses.
