I’ve wanted the Cokin filter kit for a while now. And why’s that, you ask? It's because there’s a reason landscape photographers seem to like the Cokin system so much. The idea is great: rather than screw special filters onto every lens, just buy a filter holder and slot any filter into that holder. Simple. It’s much better than having to buy a filter for each lens or even buying a big filter to use with step down rings for various lenses.Enter this filter pack from K&F. Unlike the Cokin equivalent, it comes with not just the holder but screw on adapters for almost any lens size in addition to all of the filters you possibly need. It is honestly fantastic value for money.Now here’s the rub. I’ve tried the Cokin system in the past because my husband uses it. Having now used this K&F, I honestly can’t tell the difference. The filters are plastic which means they won’t shatter and the effects you get are gorgeous.I’m not a professional but I’m a keen amateur and I think that the creative options that this pack gives you is amazing value for money. All of the filters come in filter wallets and, as I say, step down adapters are supplied for any filter thread size you can imagine.This saves so much time because it means that any size you possibly need (even for lenses you don’t yet have) is ready for you when you do.So for example, I have a 52mm lens, and it’s no problem. Pop the adapter on the lens and then the filter holder. Pick whatever filter colour I like and away I go. It’s actually makes for a load of fun out in the field because even messed up shots now have entertainment value.I’ve read some people say that Photoshop can do the same thing. Erm excuse me, but do they know how much Photoshop costs on a monthly basis? Not everyone uses Photoshop or even wants to, so I don’t find that point valid at all.If the argument is that you can simulate filters using an iPhone app I’d say yes but only to a degree. To my eyes the results from iPhone apps do not look as gorgeous as with these filters and often they just look weird. In my view there is no substitute for real filters and there is definitely not anywhere near as much joy in using the real deal.As you can probably tell, I think this product is brilliant.
