Now that I have an ultra-wide-angle lens with a bulbous front element on the way, I'm thinking about how I will care for that semi-sphere of coated glass.
Since purchasing my first quality lenses back in 2005, I've had the habit, for better or worse, of using UV filters to protect them. Over time I did learn to remove the filter when shooting with harsh backlighting or side-lighting, but I've kept the UV filters on 90% of the time outdoors.
Because of salt-spray, the beach is one place I've always kept the UV filter attached, but there is no doubt that I will need to clean that bulbous beauty from time to time after trips to the beach.
I like the idea of Purosol and microfiber and/or Kimwipes. (Have I gone off track already?) But I don't understand how Purosol works--if it does. We use up plenty of Zeiss spray in our home, but mostly for eyeglasses.
And of course when I clean my lenses, I'm 99% of the time cleaning the UV filters.
What works without affecting the lens coating? What works for typical dust and light grime, and what would be needed for more stubborn sticky stuff, such as tree sap?
Finally, has anybody invested in an air-compressor that blows clean without using propellants?
Thank you!
