Title: 90V lens oil on shutter blades
Post by: vitdev on February 22, 2024, 12:21:41 PM
I've seen a few people here complained about 90V shutter sound. It's definitely louder than 55V, but I can't say it's louder than XCD 2.8/135, although it's much closer to the front glass and, thus, very visible.
I've noticed (I guess oil) stains on it as well as that blades are not in the same plane compared to 55V or 135 shutters. Have anybody else noticed the same?

Hasselblad responded that it's expected to happen as they use small amount of oil on the mechanism to extend its lifespan. Not sure if it should spread to shutter blades though. 


Does anyone who got 90V here have oil on shutter blades?

Same here but no incidence on the functioning of the shutter.

I asked Hasselblad about it but got an evasive answer.

Kind regards,

Same here! I asked B&H and Hasselblad. HB gave evasive answer, but they responded after B&H told me to return it, which I did.
I just received a replacement (three months later) and it has a similar issue, although less oil, and blades seem to be flatter (the first lens had space between shutter blades).

I also got 28P recently and shutter is pristine clean there too.

Could you upload a photo of your shutter blades?

Of course. Here is a picture of the shutter blades of my 90V.

In the past decades oil emerging from a central shutter always indicated a problem. None of my XCD lenses (not ,,V") has visible oil and none of my other lenses with central shutter have that. Actually I would like to hear an explanation from a Hasselblad engineer why this is no longer a problem if a fast moving shutter sputters oil inside a lens. Unless there is proof that this is not a problem, I would regard that as serious defect.

Naive question but how do you close the shutter like that?

Ditto for any oil on aperture blades; and if it's on the shutter, it will eventually find its way to them.  I still won't buy an older lens if there's oil present.  They eventually gum up and stick.

That's exactly how it is. Let's be honest.
Anyone would consider oil on the shutter or aperture blades of a used lens to be a serious defect.
 
Anyone would probably not buy this lens and if they did, they would only do so at a significant discount.
