No issues whatsoever. Clear and renders color well. Do not tighten and over torque.

The product was delivered as promised. The packaging was good and filter its self felt solid. In early tests it seems fine.

特別、他のメーカーと詳しく比較したわけではありません。いままで、国内メーカーのフィルターのみでしたが、今のところ、違いを感じられません。ちゃんと使えます。長い間使うと差が出たり、詳しく比較すると何かが違うのか分かりませんが、私は、これで十分と思いました。価格はかなり安く、だからといって、品質に明らかな差を感じません。

(Text translated from my German version from Amazon Germany)I am an long standing HOYA-/B&W/Nikon-Filter user and fan. Never even thought of using anything else than these established brands. Only the fact that a load of filters I needed were not in stock brought around the situation for me, having to ‘’look around’’.Then, stumbling over this idea of ‘’buy filters- PLANT TREES’’- I had a good look at these GOBE-Filters – main thought in my head at the time was ‘’ well, if it’s rubbish I can always send them back’’….I ordered UV/C-POL and Flex-ND filters for various lenses – both from Amazon Germany and Amazon UK. Wanted to experiment. They were delivered fast and perfectly packaged. Looking at the Invoice I do have to say: wow – loads of money saved compared to what I am used to when I buy my Hoyas etc. – loads of brownie points with my wife this time round!Packaging is perfect, strong plastic filter box packed in an brown recycled cardboard cover. Inside of filter box is foam, very dense and holding the filter in place very firmly. I recommend that HOYA and the other ‘’big ones’’ have a very long look at this – and learn – since most of their filters are at times loose inside the filter box and can move around. There will be people criticising the rather obvious fact, that the plastic filter box can be a bit fiddly to open – I myself say: my filters are very safe, no filters falling out of badly closing containers and floating around my bag. These filter boxes are also extremely dust-proof. Highlight: every filter comes with an optical cloth – Hoya, Hoya Professional, B&W, Nikon and the others – hardly ever - at least not with mine.The filters have a vry slim build, but are I their mechanical make-up very accurate, surprisingly sturdy and fit into all threads of all my lenses ( metal and plastic threads ) without any hiccup. Glas rests neatly in the ring, no wobbling or clattering. The quality of the Glass seems fine and even the C-Pol’s do what they are designed to do. Although the filters have a very slim build, they do actually give an impression of reinforcing the (dodgy?) plastic threads of some lenses quite considerably. Fit is snug and perfect ( not always the case with all my various filters on modern lenses with plastic threads).The very flat/slim build of these filters can be a plusWe made a few technical comparisons with my Hoya’s, B&W’s etc.The Filter ring’s are thicker and heavier, which does not have to be good or bad. The optical comparison right up to print size of 50x70cm does not reveal any noticeable variations even if I try hard to find a fly in the ointment. I can not confirm any quality issues in comparison ti the known brands – even though this was expected and even ‘’hoped for ‘’ since we all are so loyal to our brands and hate to stray…. The usual thinking pattern of ‘’if it is cheap or reasonable it has to be is of inferior quality’ ’has – in this case – just gone out of the window and we really have to rethink that ‘’baloney’’ – myself first ,since I am right up there with ‘’them’’ thinking that way.Super! Up to here everything seems just perfect. I have no idea how GOBE do this, but to deliver such a quality and perfect packaging fur such ‘’small money’’ and then on top of that plant a load of trees in Madagaskar – I pull my hat in respect– this is the moment me old grumbling Brand-Nutter has to shut it and get on with it!I have now checked through the sizes from 77 down to 52mmand can not find any issues for daily use. I have been reading about grey and colour variations – I can not confirm any of this with even a single one of my 15 Filters I now own – absolutely nothing – even if I try hard ( which I tend to do). There seem to be issues with the C-POL filters not delivering – I honestly believe that these complaints are User based mistakes which can happen easily, since working with C-Pol’s is not always as straight forward as one would wish. Working C-Pol’s can be a challenge at the best of times, all down to situation and lenses used.Looking at the ‘’value for money’’ aspect of these GOBE filters they clearly outrun all the others – top position. When I look at the sums of money I have spent on all the big brands ( of which I really cannot see visibly quality differences to GOBE) I get a serious ‘’twinge’’ in my stomach and my circulation has a quick ‘’hiccup’’ ….I am not ‘’green’’ – by no means. But this concept, the idea of planting trees all over the place has touched me somewhat. Makes perfect sense, cannot be wrong and gives me a positive feeling – perhaps even soothes the ‘’whinges of my bad conscience’’ somewhere in the background – a little….It seems that a colleague within our PR – League has had a brilliant idea and has set it up just right. Well done, a very complete and round package.Summing things up: no minus points, all just right ‘’up there’’, absolutely NO REASON TO NOT PROFIT OF THIS PRODUCT – I recommend GOBE fully.But, should you still have this little voice in your head ‘’cheap, unknown brand, grumble, is this really good stuff, mumble’’ then get the SCHOTT Versions of the GOBE filters.We now are talking different league – Schott can easily be compared with Swarovski, Zeiss and Leitz – I know Schott from medical devices and astronomical use. In direct comparison to Schott the Hoya’s, B&W’s and even the Nikon’s could be in trouble – not much, but just that little bit!And even then the GOBE filter are a bargain!I have learnt a lot and am very happy with my GOBE’sRecommended, get’ em, plant trees.......

Pros :- Good built quality- No added color to the final resultsCons :- Mine came with lots of tiny dots in the glass ( Maybe defected item ) And it seems inside the glass itself!These dots makes the cam go out of focus ( coz it try to focus on the dots on filter surface all the time ):: Update ::The seller was very understanding, And sent me a brand new one that works really goodNow I can use the filter with very good results.No more focus issue, And the colors are naturalCPL works as expected now
