This review is for the K&F Concept 58mm Lens Filter Kit Slim, provided by Hi Shop for review.This kit comes nicely packaged with a travel case that fits the filters neatly and snugly in place. The filters included consist of 4 slim, well machined pieces and clear glass. The 4 filters included are ND4, FLD, CPL, and UV. The side of the filters is laser etched proudly with "Japan Optics", showing their level of quality with concerns to the choice of glass used. Japan has been a long time leader in photography optics and is well known for their quality of glass.This kit provides a diverse selection of filters, to allow those on the go the ability to select the right filter for the subject without taking up a lot of space in your camera bag.When compared to more expensive filters on the market, these appear to perform equally well without the high price tag attached.Pros:* Light weight and compact* A nice selection of filters* Well made with clear glass* Cheaper than more expensive products without sacrificing quality.Cons: As of now, there are no real cons associated with this product. For the money, you're getting a quality set of lens filters with a self-contained travel case.In conclusion, this is a nice compact filter kit for the money and will do well to compliment any photographers 58mm collection without costing them a lot of money. If you're in need of lens filters, K&F Concept so far has proven to be a viable option.
