I recently found myself in need of a lens cloth as most of my lenses had some form of dirt or oil residue on them (well the filters rather than the lenses themselves) and so I decided to compare some of the different ones available to find the best one for my needs. Luckily comparing lens cloths is quite easy for me as I work in a camera shop and we use the ones we sell in store so I could give them all a 'test run' to pick the right one for me. The hama micro lens cleaning cloth was one of the ones I tested.
The lens cloth comes packaged in a small triangular cardboard box, with a little 'viewing screen' in the middle to allow you to see the cloth. It opens via a little tab on the back and can then fold out flat, this means that you can continue to use the packaging as storage for the cloth to stop it getting grubby between uses, but this is more fiddly and less rugged than something like a plastic container.
The cloth itself is 80% polyester and 20% polyamide, 20cm square and a drab grey colour. The 'weave' of the material is quite fine but easily visible and if you run the cloth across the back of your hand it feels very smooth, however if you touch it with your finger tips the texture seems much rougher. Due to the nature of the material it doesn't shed fibres, so you can be sure your lens won't end up dirtier than it started!
Now comes the important part - how does it perform in terms of keeping your lens clean? Personally I found the material is perfectly fine for 'dry' use such as simply removing dust although as the cloth seems to create no static so it can take a few swipes to remove all traces of dirt. The main problem I discovered is that it is not suitable for using for a wet clean. It's quite common to get water marks or grease on the front element/filter of a lens and in the case the best way to get rid of it is to use a lens cleaning fluid such as ROR (residual oil remover) and wipe with a cloth - this particular cloth isn't at all absorbant and leaves streaks across the lens, making it next to useless for this particular application.
Price wise this can be purchased for around £3 to £4 in the shops.
Overall I probably wouldn't recommend this lens cloth - while it isn't bad, it's only suitable for dry lens cleaning and isn't really any good if you have any watery/oily marks and this is a pretty major issue for me.
