Cognisys products - anyone used them?

The title really sums up the thread, I might be able to scrape together enough to afford some Cognisys products - sadly they make such a good range that I'd rather want all of them (even though I can't afford them).

So I'd be interested in hearing if any here have used them and what their experiences are of them. The Stackshot would seem to be a very good choice for a macro fan (esp as I do like doing focus stacks when given the chance) - though of course then comes the question of regular VS extended rails.

The other items such as their stopshot present a massive wealth of options for timed or tripped shots and I also notice that they have some simple all in one beam setups on the market as well now - even more interesting is their external shutter for aid with highspeed photography during brighter hours.

I have the stackshot and it works great. I use it with microscope objectives. A regular macro rail would not be precise enough on it's own to move the camera is the tiny increments that are required.

I know some build their own, but I am not really handy with these sorts of things. I thought it was "cheap" enough to save the hassle of trying to fiddle a set up since I was also starting from scratch.

I have not used it that much, now with my twin boys, I do not have much time to set everything up. Also, I do not have a proper x,y,z platform for subject positioning and it gets really frustrating. I need to complete the set-up, it is on my list of things to do!

You can find a lot of discussion of their StackShot macro stacking system in another forum, by using their search function:

I hope this suggestion is helpful.
