Title: MF sensor cleaning
Post by: BernardLanguillier on May 07, 2017, 09:31:16 am
Hi team,

As I keep getting used to my H6D-100c, I re-discover issues long solved in the DSLR world such as... sensor dust.

I was wondering what MF owners consider the best in class sensor cleaning solution these days? Is Visible dust still the reference? If they are, which of their products are recommended for MFDBs?

Thanks.

Cheers,
Bernard

I use a little blower like this one. Works very well.

On the minus point, it looks like the product of an incestuous union between a medical device and a sex toy. The camera does not appear to care.

I use a blower and E-wipes. Most of the times blower can remove any specks from the sensor. Cleaning a sensor on MF bodies (where you can detach the sensor unit) is so much easier than on DSLRs. Unfortunately, none of my Nikon DSLRs have the sensor dust issue solved ;-), therefore I always drag the Visible Dust brush, fluid, swabs, and loupe with me when traveling with DSLRs. Loupe and brush can be useful with H6D as well.

Since I got the Iq3100 I have never needed to wet clean it. I use s blower often and that keeps it nice and clean.

It's in the user guide (from Hasselblad.com if you don't have it.)
I use e-wipes very occasionally.

Thanks.

I just did a quick search on E-wipes and found within seconds 3 reports saying that these leave very bad streaks on sensors, one user claiming that it was un-recoverable on his a7r. ;)

It is possible to clean anything very badly. it is easy to over wet. Streaks are better than scratches though.
With MF the sensor is right there in front of you. If you have streaks then you just do it again.

If someone used it on their a7r then they should sell it for whatever they can get. If Sony recommended e-wipes then they probably meant for TVs.

Cleaning MFDB sensors is relatively easy compared to a DSLR.  Rocket blower generally is all you need. Next step you can use a dedicated lens pen for quick touches. More thorough cleanings with a sensor cleaning kit.  See, https://www.digitalback.com/product-category/0-digitalbackcom/

E-wipes were once sold pre-moistened - they stopped (to my understanding) due to issues with the preservative used screwed with the latest CMOS sensor technology.

If a rocket blower can't get it, I've used both the Artic Butterfly product or the E-wipe setup Ken linked to from CI.

Thank you all for your kind inputs, I've ordered a set of Visible dust products.

Brad Kaye has written a very nice detailed article for medium format sensor cleaning that outlines some of the challenges, best practices, and practical solutions.

Thanks a lot Steve, I will at least soon own the recommended blower.

I use a blower and E-wipes.  Be careful though . Managed to get a tiny scratch still.Too late now though wish I had just used the blower brush which is what I usually did.

Do you know what caused the scratch? I got a tiny raindrop on my sensor last weekend as I was changing lenses which left a watermark on the sensor. I am debating whether to try to clean it myself or just send it to Hasselblad in New Jersey.

If it's a rain drop, a quick wet clean and you're good to go.  If you do the wet kit from CI they include a piece of plastic that should be the right width to let you do it in one quick swipe.

This is not rocket science. You are not cleaning the sensor or the technology. You are cleaning a piece of glass. I seldom clean the DSLR but MF is too easy.
You blow the loose particles away before you wipe if necessary.
The E-wipes are individually sealed. If you somehow managed to scratch the glass you probably ignored the instructions to only use the same piece of cloth once and were too vicious attacking it.

The sensor in the digital backs is quite easy to clean. I have done it a number of times. However, the sensor in the X1D seems more difficult to clean....not as accessible. It appears that one might easily damage the alignment of the sensor.

[Do you know what caused the scratch?]

I have this set up h3d11 39 since 2008 and give it a blow with a rocket before each shoot. I had a couple of marks could have been a tiny drop of moisture.  It was stubborn. Actually let it sit there for a few months and then I decided to get the magnifier out and look at it. Gave it a few blows then got out the wipes and took it easy a general overall wipe. it was still there so got out the sensor swab & fluid thats for getting into the corners and gave it a gentle wipe. Dust gone scratch there now. Its still almost €1k to get it replaced so will ignore it. More an annoyance .Scratch is marked on this pic
