I recently purchased a used sigma lens. Te advise given in the shop was very good and the assistant helped me pick the correct lens for the job. I am so pleased with my purchase. However I feel duped on the price of the lens, the assistance assured me the price of the lens new would be £400 plu. The used lens was priced at £270 which appeared a very good price. When I went home I checked the price of the lens online for a new lens and was shocked to find new lens priced at £300. Whilst the service in the shop was very good I don't think I will be a return customer as I feel the assistant mislead me regarding the value for money the used lens was.
