The Sigma 35 mm f1.4 is a brand new lens. I purchased it in December last year. As I will visit Uganda in May/June 2013 and will visit some rough areas it seems to me a good idea to wrap this Sigma lens also in a protective LensCoat Cover.
As a LensCoat Cover for this lens did not exist I mailed with LensCoat and asked them about the possibilities.
They replied within a very short time they could make a custom made LensCoat Cover for me and so they did.
Within three weeks I received the LensCoat Cover at my address in the Netherlands. And it fits perfect.
As I will roam the rainforests and some (very) dry areas of eastern Uganda in May/June I am sure the LensCoat Covers of all my lenses will protect them from rain, dust and scratches.
Expensive? Yes, but worth it...
