any shops that allows the customer to try the lens w/o the obligation to buy? I have tried quite a few shops already and some of these shops are considered by CS as reputable shops. I want to buy a Tamron 17-50m f2.8. I have read alot of good reviews and it's highly recommended. But still, these are still opinions and I feel that image quality is still subjective.
hope you can recommend a shop that does this for their buyers. thanks!
