I haven't seen the dictionary Stefan refers to, but again all those I have seen, and also Encyclopaedia Britannica, all use "lens"
Even the town in France called Lens has no e on the end!

It's only since the advent of internet forums that the spelling lense has crept in at all. I presume it's because some writers have mistakenly taken the plural lenses to indicate a singlar of lense.
I think we can take it that in our context lens is the correct spelling.

I've had several long tern saved searches and the system has worked very well.

Against the light shots will be the enemy of that scratch, but mostly you should be OK unless it's very bad. The traditional cure is to paint a scratch out with black paint. This stops it relecting light and causing flare.
How easy that would be is a different issue.

Your zoom lens doesn't change the size of the glass as it zooms, so the aperture value changes.
There are ways to keep a constant aperture with a zoom, both mechanical and optical, but these are expensive solutions, hence a higher price. Most zooms have a variable aperture.
