I picked up a Konica Big Mini from a charity shop today for the very reasonable price of £5. Pleased!
It did have a very unsightly accumulation of dust in the lens, or at least behind what appears to be some sort of filter, or lens protector on front. I was a little concerned initially, but it turned out to be two screws and a very quick job.
There are two screws, one either side of the extended lens.
Unscrew these and pull the front part of the lens off. Bit of a blow and a wipe and all the nasty little bits of fluff were gone!
Put it back together and I have a nice clean lens!
Im looking forward to trying this camera out, I’ve read a lot of very positive opinions on it. I shall post my thoughts as soon as I have had a chance to run a film through it.
