Obviously I had to have a little play to see what the latest one would produce. I started with a piece cut from my corkscrew hazel bush which had fully opened catkins and the remains of a flower, now fading rapidly.
The MSN-202 has to be closer to the subject, about 32mm and really gets in close. These are the results of a focus stacking session.

As can be seen, especially in the first two stacks, there is a limit to the depth of field as the focus range has limits on the 70-200mm zoom lens I use on the 50D otherwise I am delighted with the results. I don't think this one will be very easy to use hand held, to say the least.
There is a MSN-505 with a diopter of 32 but with its subject distance of 18.5mm I don't think I will be tempted!
