Bought a Hasselblad Glassless Filter Mount!

[Daniel Unkefer]

Hello All,

First one of these I've ever seen, just bought it! The Glassless Filter Mount B104 for the 40mm F4 C Distagon. I've cobbled one together, using parts and some black electrical tape, but this is the real item

Paid for and should be shipping soon:

Congrats Daniel. I've never heard of a glassless filter mount....how do they work and what kind of filters to you attach to them?

You unscrew the front ring, and drop-in (carefully) the glass disc, then it screw it back together. The Filter Mount bayonets onto the front of the 40mm F4, and works with the "Buick Tyre" Lenshood, as we affectionately call it around here.

From my previous experiments, I'm fairly confident that my 103mm Sinar Norma Glass Filters will tightly fit in the #50628 Filter Mount 104, as it was called. I have UV, Light Yellow, Medium Yellow, Dark Yellow, Orange, Yellow-Green, Light Red, Dark Red, and ND filters in this size. You can also cut down 4" Kodak Wratten Gelatin Filters of all sorts to fit the Filter Mount. I have some 4" circular pro filters which also might fit.

So I am set. I particularly like the Sinar Dark Red with the 40 F4 Distagon so far.

Here is my Final Solution - Sinar 103mm to 40CT*

After many tries, here is my final solution to putting Sinar 103mm Glass Filters onto the Hasselblad 40CT* Glassless Filter Mount.

Applied adhesive-backed foam (made for camera light-trapping) of the appropriate thickness, cut with my rotary trimmer. Applied the sticky backed foam all around the Sinar Filter, and it fits very tightly, so I am pleased with the end result, shown here:

Here's an Instant Proof shot with the Red Sinar Filter

Fuji 3000EI Speedy, Very Overcast Day. Minimum Focus Distance, 500C/M with #52051 Meter Prism Finder moved forward until in proper focus. Sinar Dark Red Filter. See No Vignetting! The dark red filter lightens the dark red flower petals, of the "burning bush" in my front yard. The NPC Polaroid Back produces a "light leak" from the release button on the front. I will soon be covering the inside of the back with black wide vinyl tape, that should seal the leak.

I'm also using a 4X Neutral Density in Sinar 103mm with the 40mm F4 C Distagon. Great Lens!
