Most of my lenses (Canon) have a 58mm filter but I have one lens with the 52mm thread. When the supplier offered me the opportunity to sample one of their kits I was happy to give it a go. The lens hood seems fine to me – it screws onto the lens or the filters easily & doesn't feel like it is stripping the thread as some cheap accessories do. It is difficult to assess its performance given that it is February and there isn't much sunshine around. The pinch-centre lens cover will attach even with the lens hood on (although it isn't very secure). You can't put on a conventional Canon lens cover with the hood in place nor, unlike the official Canon hood and another aftermarket one I have, can you reverse the hood and store it on the lens.An initial check of the filters for scratches and blemishes didn’t reveal any problems. The four filters are CPL, UV, ND4, FLD. I don't have much use for an FLD filter although you can play with it to get some interesting effects. I use UV filters as lens protectors and this one is fine. The CPL also seems fine to me, doing the job as expected. So far I haven't had much opportunity to try out the ND4 – but I enjoy landscape photography and use this type of filter regularly so I will test it out in due course. All the filters are threaded both sides. They are slim and have a quality feel about them and so far haven't revealed any flaws. The filters also accepted two other lens hoods I had as well as the one included in the kit. The lens pouch isn't bad either – reasonably well padded and easy to slip into a bag.I have a mix of expensive and cheap filters and rarely notice any difference between them. If you are new to using filters this would be a good set to start off with. If I were the supplier I would offer the set with an alternative to the FLD filter – maybe an 81A warm up filter but this is obviously a personal preference. One other thing to note is that the references to particular camera brands in the description could lead people astray – you need to look out for the thread size relating to the lens(es) you wish to use the filters on which is much more relevant than the camera manufacturer.
