General Brand 58mm-Series 7 Step-Up Adapter Ring (Lens to Filter)

The Leica Telephoto 90mm f/2.8 Elmarit R 3-Cam Manual Focus Lens has a 55mm filter thread. Use this adapter to mount Series 7 filters to it. General Brand 55mm-Series 7 Step-Up Adapter Ring (Lens to Filter) B&H # GBAR55S7. Use this retaining ring to hold the Series 7 filter in the adapter. General Brand Series 7 Retaining Ring B&H # GBRRS7.

As the 58mm filter you own is smaller than the 62mm filter threads on the lens you wish to purchase, you would need to purchase a 62-58mm step-down ring, such as the Sensei 62-58mm Step-Down Ring, B&H # SESDR6258. Do note that when using a filter with a smaller filter thread on a lens that has a larger filter thread, you may encounter some vignetting due to the smaller filter thread size. (not guaranteed, but it is a possibility of which you should be made aware).

You would need a 58mm to 72mm step up ring:https://www.bhphotovideo.com/c/product/809629-REG/Sensei_sur5872_58_72mm_Step_Up_Ring.html

No, this ring is to attach to a lens with 58mm filter threads.

Unfortunately, I am not certain. The above is a general brand item, and the image used may be an example of the step-up adapter ring, but not be the actual adapter ring that is received. That being said, if you purchase the above item, the step-up ring you receive would be designed to allow a series 7 accessory to be used on a standard 67mm filter thread.

No, the General Brand Hasselblad Bayonet 60-Bayonet 50 Step-Down Adapter Ring (Lens to Filter) enables a filter with an attachment size of Bayonet 50 to be used with a lens with an attachment size of Bayonet 60. You cannot use it with a 52mm filter.

This adapter ring is not female to female.

This General Brand Hasselblad adapter allows a filter or hood that has a Bayonet 50 mount to fit on a lens with a Bayonet 60 mount, therefore it would be the opposite of what you need.
