cleaning the sensor

[braver]

I've been swapping the digital back between the 503cw and 907x, and at some point left it in the bag without the cover -- don't know how it happened.  Then another day I reviewed my images and I see a worm, and I worry about a lens, but it's a small streak on the sensor.  I hope it's just a smudge.  How do you clean it?

I must say the design where the sensor is exposed is going to keep us all on the edge.

Would at first blow it out with the rocket airblower and afterwards wet cleaning with eclipse sensor fluid and swaps.

Usually it is only residue of something, actually it is quite hard to scratch the glas itself.

Most often, the application of an air blower is enough, and the wet cleaning step is not necessary. The sensor 907x is straightforward to clean as it is so accessible. I would use E-wipe for 907X, as it is suggested for H6D.

No need to be on edge about it, braver. Just handle the back as the piece of precision equipment that it is, cover the sensor with the cap when you are not fitting it to a camera, and all will be well.

I've blown some little speck or two of dust off the sensor with my Giottos Rocket blower two or three times, and I swap the back on and off my 907x and 500CM quite frequently. It's really no problem at all. Just treat is with ordinary care and it will be fine.

Well if you change the baks in the field there's always a risk to touch the exposed sensor.  The body has sharp metal protrusions, you can drop it, etc.  This is my first digital back, or any back at all as I got the 503cw for this (with the film back:), and I'm amazed at how much more vulnerable the setup is in the field.  I try to change lenses carefully but this is next level of care.  I wish it had the dark slide equivalent that you'd insert before detaching the back to ensure the sensor is never exposed.

I guess I just don't worry too much. I'm very familiar with handling precision tools and optical devices in the field and have never nicked or damaged anything through attention and care. Just try not to juggle too many things in your hands at once and stay focused on what you're doing, that's all.

Exactly, yes.  I've been fortunate so far.  So I had the sensor cleaned and looks like it got the streak out.  Whew.  Now always to cover it if not attached and right away.
