Window in Kraków, 2016. I took several hundred pictures on this trip and this is my favorite. X-T10 straight out of camera, XF 56mm.

I imagine the reason for not retasking the delete button is to avoid people accidentally deleting shots when they want to change some menu item.

Then you don't want to put any filter on that lens. It's a decent optic as it is, but it's not the most flawless lens out there and with the pixel pitch of the Fuji cameras, any additional glass you put on the front will either soften the image or increase glare and ghosting, depending on the nature of the filter. A simple coated clear protective filter will do the least damage—Hoya, B+W and Tiffen all make good ones—but even that is going to degrade the lens somewhat. It's not physically possible to add more glass to the front and maintain the same image quality. Simply keeping the lens hood on does fully protect the front element from knocks by the simple act of physically blocking anything from touching it, and it won't decrease image quality at all. (Or in fact can help, in the case of preventing glare and flare.) If you want to keep the image quality the same, that really is the only thing that will do it. 

I wouldn't put any filter on that lens. Leave the lens hood on and the front element will be protected from everything, unless you purposefully pour water down it.

I could, but it probably won't install on my Pentax K-5ii. And since the thread says "I'll test it for you...."
