Hi All,
Thanks for the feedback.
I am delighted with the converter, it is a superb addition and takes seconds to fit and use (just remember to have the current firmware and turn on the setting for the 50mm).
I have used this lens for some portraits as well and it renders superb images with no noticeable loss of quality, it is a very good investment for any X100 series users looking for a slightly longer lens, it is also well balanced and I think I paid around £160.00 for it at the time but see they are now around £200. still worth the investment though.
They are a lot smaller than images make you think and come in a nice soft bag with rear cap and a nice sturdy lens cap, I would like to get a lens shade for it as the front element is large and can be a tad prone to flair - still a great lens for the price!!
