That era saw the influx of Polaroid style cameras iirc.
I had a Polaroid as a teenager at the time but I don’t have any recollection of filters being used with them.

Good guess, I see where you’re coming from!Tamron sp500 cat (mirror) lens?
I called it a cat lens especially for you.Good guess, I see where you’re coming from!![]()


Looks like it's sharper than mine!Shot of the exhaust pipe on my bike from about10 feet away.
I'll need to practice using it as it really does have some reach especially on an M4/3 sensor. It'll also get a go on the ME Super and I'll try out those filters.
It is lighter and shorter than I expected and with the tripod mount it just sits ion the hand very easily.

So those filters sit on the rear element presumably?
What effect does that have on focusing?
Ive never used filters at the rear of a lens but have read comments how some LF togs use the method.
Seems that the focus distance changes( similar effect to that of LF telephoto lenses perhaps ?)

Sounds like close up work on 10x8I can tell you the depth of field is about as wide the the edge of a Rizla which makes accurate focusing fun.
