Astron 2x teleconverter

I picked up one today at an op shop, came home to do some googling and to my shock google doesn't know everything! Has anyone got one? It's manual but that's fine because I'm hoping to use it with my M 50mm to do some bokehrama shots. There's a few out there with Minolta mounts but nothing here or out there on Pentax Astron teleconverters.

You are right: Nothing much to be found on the net. I only found a brief note somewhere, that Astron lenses were Japanes made and quite commonly sold together with Pentax from some major warehoses in Australia during the 80'ies.

SO: Do us all a favour and write a brief review (positive or negative) in the PF Third-party lens review section once you have tried it. Then you will be the first - and google/the net will learn something new.........

I'll also be trying it out on my 55-300 for astrophotography, I've just started getting into that as well. I'll get some test shots and do a review in the next few weeks, good idea!
