Hasselblad 50mm CF B60 lens hood - useful, or too small?
Hasselblad 50mm CF B60 lens hood - it looks awful small to be of any use. I was going to order one off of eBay, but looking at it, it doesn't appear to be deep enough to shade anything.
Anyone have experience with this? Does it help, or is it a waste?
It helps, but is too short, yes.
It's made to be used on all lenses from 60 mm Distagon to 38 mm Biogon. So it is short enough not to vignet when used on the Biogon, but too short for the other two bayonet 60 wide angle lenses.
What i have done, is get bayonet 60 shades for the 80 mm lens, and shorten them.
Hasselblad was kind enough to calculate for me by how much for both 50 mm and 60 mm lenses: by 17 mm and 15.5 mm.
Mind you: the resulting shades are not much longer than the bayonet 60 38-60 lens hood. But the optimum length still.
Because original Hasselblad shades are rather expensive, you can get those Chinese "For Hasselblad" shades to play with.
They are rather soft, brittle plastic, compared to the original ones. And they don't go on as smoothly and securely as the originals. But they work. And are very cheap.
That seems like a good idea - did you just take a Dremel to it and cut around the edges?
I had planned to use a band sander. Put it on there and let the thing 'wear' it down. Thought that would be easiest, to get straight edges, evenly long on all 4 sides.
I took a metal ruler, and scored a line on all 4 sides using an exacto knife, to know where to shorten it to.
Then i found that the sharp knife did a good job, and ran it along the groove it created some more, until it was all the way through. Took a while, but not that long that i regretted doing it this way.
The rounded corners were a bit fiddly to do, but since i was almost done, i just kept on using the knife.
I did that first on an original Hasselblad shade, which is made of pretty hard plastic.
I did it again, the same way, on those Chinese hoods, and it took no time at all. Pressed too hard on one, and the side cracked. So take care.
I just got a 50mm in a trade from one of our great Apugs and being the cheap guy I am ordered one of the ebay $ 14.00 knock offs shades. It is the same size as the Hassy one, and agreed almost too short to be of serivce.
I've put my bellows shade on the 50mm and it is much bigger, covers more and looks rather sexy too. But it is very hard to lug about the trees and limbs in fear of puncturing the bellows. Much better shade coverage.

Thanks QG - Great information as always.
I agree Lee - the bellows shade is great but too hard to travel with. You'll love the 50mm btw.
I do like the 50mm, although see the new post living with old glass.

Lee - Just read that. Yeah, I send all of my "new" gear off for CLA now - I just plan on it when buying.
Dave Easterwood should be able to get you fixed up for well under $100. Using the lens with old gummed up lube could damage the workings long-term.
