I have bought quite a few items from Calumet over the past few years because of the convenience (their Manchester branch is just over the road from where I work), the staff are helpful and friendly with a personal touch - not quite "Norm!" from Cheers but they know who I am - the prices are competitive and there is a wide selection of equipment that can be inspected much more easily than on a website. If equipment does need to be ordered it is there within a day or so and they let me know when it has arrived which is great. Their 0% interest deals from time to time are a great way to spread the costs of equipment and I have used them to buy a body and lens over the past couple of years All in all, if I do need anything photographic Calumet is the first place I check out and go to.
