naughtygoat Posted November 27, 2016 Share Posted November 27, 2016 Hi all, I am getting a Polarising and a Close up filter for my rx100 i. i can see they will screw in to my filter adapter, but I don't understand the Threaded Type business. Could anyone please tell me how it pertains to rx100 i and/or screw in filters? Been looking high and low for this info... Thnks, Vickie. Link to comment Share on other sites More sharing options...
spacecadet Posted November 27, 2016 Share Posted November 27, 2016 Filter threads are a standard pitch and have been for decades. Link to comment Share on other sites More sharing options...

spacecadet Posted November 27, 2016 Share Posted November 27, 2016 Sorry, I can't think of another way to explain it. You choose a filter by thread diameter and that's it. There is no other parameter. The thread pitch does not vary. Does this help? https://en.wikipedia.org/wiki/Screw_thread#Lead.2C_pitch.2C_and_starts Link to comment Share on other sites More sharing options...
KevinS Posted November 27, 2016 Share Posted November 27, 2016 I'm pleased with how the Sony filter adapter works for this camera. The filter screws into the outer part and the inner part gets stuck onto the camera with the double-sided tape provided. Once attached, you can remove the filter by pinching the adapter with thumb and forefinger. It's well worth the added bulk for the convenience.

Allan Bell Posted November 27, 2016 Share Posted November 27, 2016 There is no filter thread on the Sony RX100 to my knowledge. Allan EDIT Did not know about an adaptor. ITMA So the adaptor takes a 49mm diameter thread filter. Allan Link to comment Share on other sites More sharing options...

I know I need a 49mm size filter. I want to know if it should be single or double thread. I might be confused. Don't really wanna know the ins and outs of screw designs! Vickie.

Allan Bell Posted November 27, 2016 Share Posted November 27, 2016 As Mark says above you need not worry about pitch, single or double thread as all filters are made to a standard these days. All you need is the diameter, which you have. Allan Link to comment Share on other sites More sharing options...

spacecadet Posted November 27, 2016 Share Posted November 27, 2016 Perhaps "single thread" means you can't screw another filter into the front of it, but I've never heard of such a thing. Link to comment Share on other sites More sharing options...
naughtygoat Posted November 27, 2016 Author Share Posted November 27, 2016 I think you might be right. I have just bought lovely cheap Hoya ones. Not double thread. I'll just change them when I want a different one. Thanks or your help. Link to comment Share on other sites More sharing options...

M.Chapman Posted November 28, 2016 Share Posted November 28, 2016 You may need to be careful using a closeup filter. The degradation in image quality can be significant if you buy too cheaply and may give problems with Alamy QC. The Marumi achromatic close-up filters seem OK though, so much so that I no longer bother carrying my macro lens with me. Link to comment Share on other sites More sharing options...
spacecadet Posted November 28, 2016 Share Posted November 28, 2016 +1. I wouldn't care to trust a single-element dioptre to QC. Doublets are much more expensive. Link to comment Share on other sites More sharing options...

spacecadet Posted November 28, 2016 Share Posted November 28, 2016 An achromat in good condition, yes. But I'd make sure I needed one first- that I couldn't get close enough with the lens I have, taking crop into account. Link to comment Share on other sites More sharing options...

Anyone know of one? Thank you, Vickie. Link to comment Share on other sites More sharing options...
