Viewfinders for Hasselblad SWC/M bodies

[Michael Mutmansky]

Folks,

I am looking for a groundglass adapter and viewfinder for a late SWC/M body with the CF lens (I have the later rangefinder for it) and am trying to figure out what my options are.

As I understand it, any of the normal VFs will work on the 41050 ground glass adapter, so I am covered with the PM45 that I have (or the WL finder as well), but I thought I might be better off with a smaller reflex finder to keep the SWC/M kit smaller.

So, I am looking around and see the chimney finder (don't recall the catalogue numers for those) and the other reflex finders that don't fully invert the image (L-R is still inverted). These are:
47070
72530

Not sure if there are others... I am trying to determine what the differences are between those two. I think it may be vintage, but maybe also the magnification?

Looking for a little insight and recommendations for these on a late SWC/M...

Thanks,


---Michael

...Also, I realize there is also the 41057 ground glass adapter for the cameras... which is the last version, but I am wondering if it will work well with the biogon lens... I think the Acute Matte D screen is worse with wide angle lenses than the older A-M screen? The biogon is going to be the most wide-angle-ish of all the lenses since it isn't retrofocal, so I doubt that it will be all that useful to spend the additional money on the 41057 over the 41050.

Input from knowledgeable Hasselblad users is appreciated.

Mine has "FOR HASSELBLAD" inscribed on it with a split ring in the center and no other markings. I suggest that you make a call to KEH as ask.

Sirius,

That is (I think) a Chinese knockoff. You can seee them on Ebay to see if they look like what you have. I was thinking about them as well (after I spotted them on Ebay), but I wonder about the ground glass focus depth accuracy and then also how well they work with the biogon (corner falloff when using a viewfinder).

What's your opinion on it? Is it the one with the gridded GG? That is a must for me (shooting architecture with the SWC is probably about the only time I will pullout the GG adapter anyway).

Thanks,

Mine may well be a kockoff. It does not have the grid background. I have had no problem with falloff or focus accuracy when used with the 903 SWC.

OK, to circle back on this, it appears that the 47070 and 72530 are identical. They must have renumbered it based on some product introduction. I was initially thininking they renumbered it when they introduced the electronic dispaly in the 203 bodies, but photos I've seen appear to look identical (with a cutout) in both product numbers, so that doesn't appear to be the distinction. Everything I am seeing points to them being identical, but there may be some subtle differences that don't appear physically.

The 41057 ground glass adpater is the newest but it appears to have been made in parallel with the 41050 and I suspect that is because the 41050 will work better for the wide angle lenses (in particular the biogon) because of the fresnel lens that they use with it. The 41057 uses the stock/standard screens. That is great if you want to change the focus aids or don't want the gridded screen, but I think it is a compromise for the wide angle lenses somewhat. I've read a few comments that they don't work the best with the shorter lenses, in particular the 38mm biogon.

I don't know how well the Chinese versions work. I think it really depends on the fresnel focal length they use and how coarse the fresnel pattern is whether it will be a good or better option than te Hasselblad version. They are 1/2 the price, though.
