The truth is that the product is amazing, but it came with a lot of dirt. I had to give it a very thorough cleaning and I will still have to take it to a specialised shop to have the lens and mirror cleaned as I am seeing black spots of dirt on the viewfinder. I was hoping that BackMarket would at least deliver a clean product even if it was used but it seems that is not the case. Anyway, the product is very good and works better than I thought it would. So if you don't mind paying extra for cleaning, you can buy it.
