how could you ever live to regret such a paltry investment ;-)I may live to regret it but I purchased a cheap one off ebay for just over £10, if I don't get on with it then i'll get the Kipon at a later date, I can always leave the cheap one on the small lens
My tip is this:tried it a music festival, I struggled with the focusing but I think I need more practice
I would imagine its the same steamer, we were in the right place at the right time when we saw it sailing into the isle of WightHi Martin,
Nice shot. I seem to remember taking a trip on a paddle steamer called Waverley back in the 1960s when it was on the Clyde. You could go down to the engine room and watch the pistons. Could this be the same vessel?
@gnarlydog australiaSquare bokeh balls were OK for some subjects but really became a bit much in most cases for me: I wanted round speckled highlight, not hexagonal, round!
The commercially available adapter for Pentax-110 lenses with aperture has been reported as a bit rickety and finicky to operate.
I wanted simple but good
So, I sourced a diaphragm with the potentially right dimension to be inserted between lens and DIY adapter.
Luck was on my side and the whole retrofit of my existing mounted 70mm f2.8 lens went smooth and fast: a couple of hours and I had this:
the diaphragm is an inexpensive Chinese offering on evilBay. It required minimum adaptation and I love the high-count blades aperture gives round bokeh balls even stopped down a bit

hmmm, a C-mount adapter on its own has some thickness and that will leave you with very little room to work with...@gnarlydog australia
I have decided to make an adapter with a diaphragm. I am going to machine some aluminum to make a piece that I can attach the Pentax 110 lens mount to. I will put a diaphragm in the aluminum bit and then glue the aluminum bit to a c-mount adapter. They I can use it on all my 100 lenses.
I want to be sure I understand the math correctly. The flange distance for my GX85 is 19.25mm and the flange distance for the Pentax 100 is 27mm so I need to make the total depth of my adapter 7.75mm from the back flange of the c-mount adapter (that sits against my camera body) to the back of the glass on the lens. Is that right?
I was planning to make the inside of my aluminum adapter 16mm and I am buying a 16mm diaphragm.
