Sigma announced a new kind of protection filter. It’s made of Ceramic Glass and is water-repellent, scratch resistant and 10 times stronger than conventional filters:

Interchangeable lenses are the most important element of photographic expression, and to the photographer they are a valuable personal asset. To help photographers continue to use for many years the lens systems in which they have invested their time, knowledge, and budgets, SIGMA has developed original lens filters that meet the company’s high standards of excellence. In developing its new protective lens filter, SIGMA has leveraged an unprecedented cooperative relationship with a glass manufacturer, resulting in a completely new type of glass called Clear Glass Ceramic. Featuring this advanced material, the SIGMA WR CERAMIC PROTECTOR is a highly reliable filter with outstanding protective capability.

With many applications in aerospace and other industries, glass ceramic is an extremely tough type of crystallized glass that serves as the foundation for Clear Glass Ceramic. While featuring the high transmittance required of optical devices, this advanced new material combines greater hardness than chemically strengthened glass and greater flexibility than sapphire crystal glass. These qualities make Clear Glass Ceramic the ideal material for protective lens filters.

Reality Scanner: “I think Lumix-users should know, that they can do easy focus-stacking (like the Olympus E-M1 now does in camera) from their Lumix 4K-Post-Focus files now with the latest version of HeliconFocus-software.

Johannes: “Nikon and Canon are doing quite a good job giving the newcomers affordable excellent glass with the Nifty Fifties. It is hard to find something comparable@ µ43.  I recently did quite a bit of work and photos to experience the Nifty-Fifty-ness as well as looking for a solution for the µ43 community. I did 6 blog entries on this topic, 6 are related to µ43 and 2 are related to get the APS-C and FullFrame experience with the Nifty Fifty.
The summary is the last blog entry http://delightphoto.zenfolio.com/blog/2015/12/-43-for-photographic-beginners-part-6-the-comparison-of-the-sigma-s
But the other ones are nice as well:
