Well…so far this is it!
Surprise, isn’t it? There was over 300 manufacturer in TLR world in its hey day.
But only handful of variations…pretty much disappointing. In short, they are all look the same and works the same,
with similar or lower quality spec than Rollei.
How come, such a singularity possible in such fiercely competing business area?
