Hasselblad filter converter?

jdhart73 · Jan 20, 2011

Does anyone have any recommendations for a filter converter for the 500CM with 80 and 150 lenses? I believe these both take the Bay50 filters? I have seen a few converters that will allow you to use screw in filters in 52 size and I have also seen some converters that are drop in that allow you to go with a 63 drop in type filter.

Opinions on easiest set up? I am mainly wanting to use ND filters for daylight shooting, possibly some color filters.

Thanks!

I've read on Photonet that 52mm may possibly vignette the 80 planar. This may be bunk but if you need to stack any it seems reasonable.

There are generic Bay 50 to 52mm but I'd look to go 58mm because if you use a screw on hood then a filter it seems prudent to go 58mm if possible.

What lenses are you looking to filter?
edit:
opps sorry see you have an 80 & 150
are these both "C"?

Hi Bruce,

As of right now just the 80 2.8 and 150 F4.

I meant are they the older "C" compur versions that were bay 50 (the newer "CF" Prontar are Bay 60)

I have mostly Bay 50 accessories now but when I was building my kit for my "C" Bay 50 lenses I went Bay50 to 52mm then 52mm to 58mm step up ring and I don't recall any vignette with my C Planar. This was with one filter inside a rubber 58 screw on hood.

The generic bay 50 to 52mm are about 5 bux on the auction site then about 3-4 bux for the 52 to 58mm step up ring. I had a bunch of 58mm filters so this made sense.

Maybe QG can comment, he'll know if the 52mm filters will vignette an 80 C Planar.

I have not noticed vignetting with a 52 mm filter on the 80, but it's certainly cutting it close. I also don't use filters too often, so it might be there without my taking notice.
There are adaptors around for larger filter sizes, which would be preferable.

Older C lenses are what I am speaking of.

Thanks guys!

I forgot to mention you could go with one of the Hasselblad Pro Shades . These have slots for square gel filters.
This would run you more but you would have an adjustable compendium lens shade for all your lenses in one.

Then there are the Lee or other square gel filter and holders that comprise of a screw on holder. You'd still need to get a Bay 50 adapter to whichever system you went with.

Thanks Bruce. The more I think about it the more I want to go with a 50 to 58 adapter so I can use standard Hoya filters. Like you mentioned I can get one for $10 on the Bay.

There often is confusion about Hasselblad filter sizes. And that confusion is used by providers of substitute filters.

Unlike other manufacturers/brands, they do not (!) list the size of the mount, but that of the filter glass.
So you have to add twice the widt of the rim to get the size as stated by other manufacturers: a bayonet 50 filter is the same size as a screw mount 57 mm filter, a bayonet 60 is the same size as a 67 mm filter, bayonet 70 is 77 mm.

So while a 52 mm filter may work on some bayonet 50 lenses, the proper size to get is 57 mm, using a bayonet 50 - 57 mm adapter.

P.S.

You can, of course, use even larger filters, but the lens hoods will no longer fit. They do with a bayonet 50 to 57 mm adapter (unless they made such a thing too wide - mine is o.k.) + 57 mm filters.

QG
Good point about the stock hoods.
I finally scored some hasselblad Bay 50 hoods for my 80,150 & 250 and they wont work (that I know of) with the step up ring solution I mentioned.

Bay 50 filters are the best way to go imo it just takes some patience to get them at decent prices. I've amassed a nice assortment for under 10usd a piece but it took diligent work for awhile. Polarizers and ND's go for more. The 'blad filters are high quality and the bayonet configuration lets them mount/unmount easily.

The Bay 60 filters go for a good deal more.

I got the B60 -> 72mm filter converter from the bay and two 72mm lens caps from the local camera shop to go with 'em. Think my total cost was around $25 for all. Quality was good and I had the 72mm filters already. I plan to just pop them off when using a hood. I also like the generic caps better than the Hasselblad ones. So far I'm pleased.
