The reason I ask is because for instance a 12mm extension tube will probably already be too much for 14mm, putting the focus plane at "infinity" already past the front element.
OK, I just tried a 12mm extension tube on the Samayng 14mm ...... and even with the subject touching the front element ....... it's still little blurred ... but not by much !!
6mm would probably be about right ..... maybe they exist as dumb versions ??
There is an original Nikon 8mm extension tube in Australia for 40 euros + postage ..... and I found a 5.8mm one as part of an expensive manual set (€99+post) .......
....... maybe I'll give it a miss .....
