Fotodiox Bayonet 60 B60-67mm Step Up Filter Adapter Ring for Hasselblad, Anodized Black Metal Filter Adapter Ring

Excellent value - 60mm bayonet side fits tight on my Hasselblad CF lenses, 67mm threads are smooth for Tiffen filters. Enables me to use same filters for Hasselblad 500C/M and Nikon F2AS (with step up ring for Nikkor lenses).

this thing works perfectly. when i put it on at first, it was a little loose. all i did was squeeze the mounts a little bit, and it fits great! blazing fast shipping, SO worth it.

This product works well, and seems to m=be well made. It is aluminum, and should be ok for a long time. I wish it were brass but that is probably just me. This adapter lets you use easy to find 67mm filters on your Hasselblad. The Bay60 filters are not always easy to find.

It does the job well at a reasonable price.

Fit the B60 Hassy lens with no problems. Allows me to use standard threat filters instead of the more expensive bayonet style.

I've purchased Fotodiox items before and have been relatively happy however this adapter is a disappointment. The bayonet teeth are small and do not fit the lens very well. I'm getting about 1/8 of an inch turn onto the lens which does not instill confidence in leaving a filter on the front. In addition, the metal (aluminum?) of which the adapter is made is thin and tends to bind with the filter so repeated attempts to mount are required. I do not recommend this adapter.

So now I'm stuck with two of these things, the 62mm and the 67mm. NEITHER ONE WORKS. This one is heavier than the 67mm,but it's so loose it spins back and forth without ever getting tight like a hasselblad filter does. The 67mm is very flimsy and turns exactly 1/4" and then falls off. Just another pissed off Amazon customer here. Off to Adorama or B&H RIGHT NOW. These go in the garbage where they belong.UPDATE: Amazon customer service is good, so I returned both items to be replaced. The 62mm was exactly the same, a pronounced wobble, a lot of play in it, truly unusable.The 67mm actually goes on quite easily but never becomes secure. A slight touch and it starts to unscrew, so I secured it with a couple of pieces of gaff tape on the end of my lens and kept it while I got another one, not from Amazon, which works absolutely perfectly. A few dollars more than this junk, but how nice not to have pieces of tape hanging on the end of your lens. So the "new" 67mm goes back tomorrow, making me 0 for 4 on this item. I do see a few positive reviews here, and I'm glad some were luckier than I was. If you're thinking of buying one, I do hope your results are better than mine. Meanwhile, may I suggest a quick look at Adorama's website?

The step up ring is well constructed. It fit my bayonet mount lens perfectly. And is easily removed.
