Hello, new to the forum and have spent lots of time browsing. Just got an S5is, and really like it so far. My question is...is it ridiculous to buy the lensmate adapter purely as protection for the time being until I really need filters, lenses, etc. And does it affect the quality of the photos? I have read that some people say it causes vignetting, shadows from flash, etc. but I am just a casual photographer (right now). Thanks!! BTW am leaning towards the 52mm cause I dont have any filters or lenses right now.
