Camera Lens Cleaning?


Recommended Posts

I have never used any cleaner on my lenses. I brush the dust off the lens and use a lens cleaning cloth in circular motions to remove any smudges. A clean cotton t-shirt has substituted for a lens cloth on occasion but I've never used a cleaning solution on my glass.

Mostly this but I use an eyeglass cleaning wipe after the brush, then the cloth.  I do my bino lenses the same way.  Regardless of the device, hold it so the lens you're brushing is facing down, so the debris loosened by the brush falls away.

I will add, don't forget to clean the inside of the lens hood while you're at it. Dust inside the lens hood can/will end up back on the lens if you put a dusty hood back on a clean lens.

I had bad experiences with this. For me and my sigma contemporary 150-600mm lens it pushed the dust to the sides which I believe is the cause of dust on the internal glass pieces (I got the lens with no dust) I switched over to using a hand-held blower to remove dust and then I used the cloth to wipe smudges off if there are any. Just my thoughts on this...

I think that dust on the inside of the lens is more likely to come from air(and dust) entering the lens body while zooming in and out. As you extend the lens air gets pulled in, then the air(and dust) gets pushed to the inside of the front glass while it tries to escape when the lens is collapsed. That's what I think happens and why it's not uncommon to see dust on the inside of the front element of a zoom lens. Quality zoom lenses might get less dust inside, but I think it's just the nature of a zoom lens to get dust inside while zooming in and out. One thing I know is that changing lenses in dusty conditions will also increase the risk of getting dust in your gear.
