Seems that the only thing of any real (potential) value in the add-on kit is the set of three filters. I looked at Amazon reviews for that filter kit, looking for indications of optical quality. I spotted two reviews where the reviewers stated that they degraded image quality when used with longer lenses. That's what I would expect if the glass is not optically flat, and with three 77mm filters for about $25 USD, well, they are not spending money on high quality glass.
I'd "focus" on buying from a reputable seller that is an authorized distributor. Anything extra you get in the deal is a bonus, and may or may not be worth anything at all. |
