Flip-Mounts are available for most of the common macro lenses, but the different models do not fit for all the lenses!
To give the best possible result, the macro lens should be as close to the port as possible and therefore we design the different models so that the lenses are as close as possible. Even if some holders are able to hold most different models of macro lenses it is recommended to order the right Flip-adapter during the order process! This will ultimately give you better results! Also note that some macro lenses are significantly different in size and will not fit on all the different adapters. Please check during checkout that you have ordered the right model!
