Congrats. That is great. I think you will be very happy with that set up.


Others may know who makes the Promaster UV filter and how good it is, but that is the one thing I would suggest checking. Just aim the lens at a light at a slight angle and snap a picture with it on and with it off and compare. You might also take a few other pictures of a subject with detail in it. Many UV filters are very good. Some, not. And you don't want a UV filter to impede the quality of the lens. Many here use B+W MRC filters.


Here are some example photos:

No UV filter, just the lens:
