I have had a Master Tech for some time but am thinking about trying an extreme wide lens with the wide-angle focus attachement, for 55-65 mm lens. I have absolutely no experience with this device. I have seen some pictures of 2nd hand wa devices and read a few snippets in forum discussions and i know that the lens attach to the device on a 6x9 flat lens board
but after that is it just a matter of attaching the device by clipping into the lens board position and pushing the bellows all the way in - then focus ? Or is there more to it than that such as setting infinity.
can anyone share their experience with this device - how practical is it to use this in the field - also i have seen 2nd hand ones from time to time - are there different models is there a model particular to my Master Tech - thanks Anthony
