Is the photo for this item wrong? It should look like the photo for the General Brand 62mm-Series 7 Step-Up Adapter Ring: female 36 tpi threads for the smaller diameter Series 7 retaining ring and male 0.75mm pitch threads to fit larger diameter lens with its 0.75mm pitch female threads.
Asked by: James M
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.

question

Can this be used to screw in 58mm accessories to a series & lens like Leica R 90/2.8?
Asked by: Amit
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.

question

Will this adapter ring work with a Nikon P610, to use with a snap on lens hood?
Asked by: Leslee
It is our opinion that no this would not work and only result in the filter falling and breaking. There are third party adapters available elsewhere on the net so that you can put a 62mm filter on this camera.

Hello ! Is that possible to use this adapter + a Bay 50 to 52mm Ring to put 52mm filter on CF lens ?
Asked by: Leo
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.

question

I have a 58mm polarizer filter and now am purchasing a 62mm lens. Can I us a step-up adapter ring to make this work? If so which one do I want?Thank you.
Asked by: Anonymous
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).
