Bay77 for Hasselblad F2.8 150mm?

ame01999 · Jan 6, 2025

I'm eyeing a long lens here, and was thinking of buying a filter/filter adapter in advance:

[Mint] Hasselblad Carl Zeiss Sonnar T* 150mm f/2.8 FE Lens - From Japan (#4) | eBay

[Mint] Hasselblad Carl Zeiss Sonnar T 150mm F/2.8 FE Lens From JAPAN #4 - An item that's hard to find, even in Japan. It works properly. ■Functional.

www.ebay.com

But my chatbot told me the lens requires a Hasselblad Bay77 size filter. I couldn't find any in existence on eBay. Is my chatbot wrong, or are such filter sizes exceedingly rare?

On another note, I couldn't find a section for Hasselblad lenses on Igor's site, just the bodies with included lenses. Let me know if I missed something obvious. Thanks!

Check the nomenclature. I think B77 is really the same as Bayonet 70. The latter are rarish but available.

Yes B70 is the size that you probably will need. Look for used B+W and Hasselblad filters to start otherwise you will need step up adapters.

I have a Planar T* 2/110 F with data bus which has the same filter setup. I use a fotodiox Bay70 to 72. There is also a Bay 70 to 78.
The 72 might be an issue if one stacked filters with the wide angle CFi FLE f/4 50 mm Distagon, but it has never been an issue for me.

Just to be sure the lens you are looking at is for the focal plane shutter Hasselblads, eh?

Also the lens in the ebay ad does not have electronic data bus connectors in the back. Is it really an FE?

No it is obviously an F-lens, not an FE as advertised.

The Filter size is B70. I had the luck of buying some for very little money many years ago. They are very rare.
