If you try to tap the piece loose you can momentarily lose control of your tool (probably a straight blade screwdriver) and you could scratch/gouge glass or bugger up the spanning slots. Look carefully at what you’re needing to do and TAKE YOUR TIME! Rushing this, especially as a noobie, will probably lead you into a regretable mistake. I’m sure most of us don’t have such tools and don’t intend on buying them…so if you do it carefully enough there should be no issues. This will be a test of your nerve and willingness to take the risk for this DIY repair. WARNING: When disassembling a lens you will likely need to remove lens elements that usually require a spanning wrench. I took picures and video every step of the way, just in case I spaced out a set of screws, the re-positioning of a part or the order of reassembly. I took apart a couple old, cheap, beat-up prime lenses recently and they worked fine when I was done, so I set out to clean the haze off my lovely “new” zoom. I took it out to shoot some bird video with my GH2 and got very nice footage, but couldn’t get the haze issue out of my head…it’s not s’posed to be there and I didn’t want to spend more on getting it cleaned professionally than I paid for the lens itself! I paid a paltry $127.50 for it, probably due to the seller describing the presence of noticeable haze on the rear element.
I received an almost pristine Canon FD 85-300mm f/4.5 lens today, bought on ebay. When putting the screws back, don’t over-tighten them. Do NOT try to blow off the dust with your breath or canned air – use Giotto’s Rocket Blower instead. When using the blower, keep a safe distance, so that you do not accidentally hit anything. Be very careful during the process and make sure not to touch any lens parts or lens elements from the inside. Just zoom out to 24mm so that the element moves down towards the rear, then blow off the dust from it using the same rocket blower. You can also remove the dust from the next lens element that sits inside the lens. All you need to do is remove three screws from the rear wall of the lens mount, then gently lift the rear lens element and use a rocket blower to remove the dust from it. Now for the brave souls that decide to do this: the process is actually fairly simple. See my “ what to do with dust inside lenses” article for more information.ĭISCLAIMER: I take ZERO responsibility for any potential damage that you might cause as a result of opening the rear lens element.
Do not attempt this if you have a couple of small dust specks in your lens. WARNING: Opening your lens will void your warranty if Nikon finds out you did it.
#Professional blower dust removal system lens how to
In this video, I will show you how to remove dust from the rear element of the Nikon 24-70mm f/2.8G lens in less than 5 minutes. I did not feel like waiting for a couple of weeks and paying a hefty sum to get mine cleaned, so I decided to do it myself. Nikon only removes dust from lenses if you pay for the service, because the normal lens warranty does not cover dust removal. While for the most part it does not affect my images, after my last trip to Utah, I ended up with a large dust particle that somehow made it into the lens. I often get plenty of dust behind the rear element of my Nikon 24-70mm f/2.8G lens.
