Re: Wide Angle Set Up for Sony a6xxx

My first version of a 3D printed ring to get focus going on the Samyang Rokinon 12mm initially (8mm later), after some refinements to get it to properly stay on the lens) worked out great only for the first few seconds of trying.

Then the realisation set in that the ring simply was not deep enough the rubber gear needs to be hard supported all the way out (or in, towards the diver so to speak) underneath the rubber teeth. if not the rubber gear (the one for the 10-18) is flexible enough and the manual focus on my 12mm moves hard enough (which I like, just hard in comparison to an e-focus lens like the SEL1650) so that manual focussing works until at some point the gear teeth flex out of the way (w/o the gear itself being pushed out of location. I tried to keep that 3D printed ring such that I can leave the ring on the lens pretty much permanently (since in order to get it to not slip I made it a split ring, rubber coated the inside and low profile cable tie-wrapped it hard to the lens and to get it off it is necessary to cut the tiewrap, which i would like to avoid (multiple times?) on a trip.

Anyway, a second attempt with the support ring supporting all the way out to the very tooth end of the gear shall be done... in due time (no diving in sight for a while...)
