GCab Posted October 18, 2008 Report Share Posted October 18, 2008 I am normally paranoid about changing lenses quickly but for some reason I took off my 50mm lens and left it lens-cap side down on a mantelpiece OVERNIGHT (d'oh) - basically forgot I hadn't put the cap on the sensor-side part. I cringed when I saw it the next day and sure enough there is visible dust. Now the question is, do I just dab at it with standard lens fluid/cloth, or does it need specialist cleaning (or products)? Obviously it's glass and not as fragile as the sensor, but equally I don't want to use an optical wipe etc. if the chemicals might attack the sensor once I re-attach the lens, or if the dust removal won't be good enough. I've kept the lens off the camera until I'm sure - any help appreciated. The body is a D300 and the vibrating dust removal seems to work OK under normal circumstances, but I don't want to introduce a night's worth of dust into the system by using the lens until I'm sure it's as clean as I can get it.

bazza_g Posted October 18, 2008 Report Share Posted October 18, 2008 Have you got a 'blower' to remove the dust? I've done this before and used a dry lens cloth to remove the last couple of specs Link to comment Share on other sites More sharing options...
GCab Posted October 18, 2008 Author Report Share Posted October 18, 2008 Good tip - found an aerosol blower from Jessops and used this at a safe distance and without shaking (so you don't get propellant droplets over the glass) and it worked a treat :D Had it in the house from old astronomy telescope days, but hadn't thought of it - thanks bazza Link to comment Share on other sites More sharing options...
