I always enjoy my visits to Calumet - I use the Hagley Rd. branch, Birmingham. The staff are extremely knowledgeable and friendly and manage to pitch their explanations a levels to suit their customers' understanding. The shop is well stocked and staff are always happy to offer alternatives for comparisons to be made before the customer makes their choice. I was very pleased to be allowed to take a 150-600mm lens into the street to see what it was capable of, I didn't think I would be able to do that. Calumet offers a high quality and friendly service, stocks a wide range of top end products and gives customers the time to browse and exchange ideas, questions etc. Professional but unhurried. Keep up the good work Calumet - it's a pity every retail experience isn't this pleasant!
