I have a TS-optics Telephoto Camera Holder, as described here:
https://www.teleskop-express.de/shop...etail-bar.html
I have used it a few time with my Nikon D5300, but as I move away from imaging it is no longer required and should go to a new home where it will be used.
Note that the sliding barrel in the back adjusts up and down to hold the camera body via the usual tripod mounting screw. The lens ring in the front is large enough to support lenses of 90mm in diametre. The lens ring moves fore and aft on its slide to adjust to fit the lens used.
A new one would cost you about $126 AUD plus shipping etc frtom Germany. I am offering mine here for $90, postage paid to any Australia address. If your interested just PM me here on IIS. Thanks for looking.
