Filters for the MS-Optical Sonnetar 50/1.1.

Now that I have a new lens cap for my MS-Optical Sonnetar 50/1.1 lens, I am also thinking of adding a protective filter to the lens as well.

I usually do not prefer filters, since a lens hood will do a good enough job to protect the lens, and modern optical coatings are so good that the lens surface can be cleaned easily if it in fact gets dirty. Actually, it is very difficult to scratch the surface when cleaning the lens if you know what you are doing.

That said, the fast F/# of this lens means that there is a very large front element, and I feel a little weary even in general handling.

There seems to be a few options when considering a filter for the lens and the hood.

I got this information from a very helpful post at EyesCoffee.com, but essentially you can put a filter on the three screw mounts available: 1) the lens side, 2) the smaller side of the hood, and 3) the larger side of the hood.

I plan on going with the 52mm filter on the lens, that seems to be the best way to take the hood off and lens cap on after shooting. We will see.
