I bought one for spectacles but will buy another for camera lenses
on 23 July 2012
I bought this as a solution to the problems caused by the cleaning cloths supplied by opticians with new spectacles that shed significantly more fibres than you are trying to remove, and then smudge the lens in the process.
Although I have used the same optician for about 20 years, the style of cleaning cloths he provides appears to change every few years. Some are good, a few really excellent and some, such as those currently provided, are truly awful. I formerly used the 'Calocloth' cloths, which appear no longer to be available, and they were very good for about 1-2 years before needing to be replaced. I tried washing one which was at the end of its life and it was useless afterwards.
The Pentax cloths are an entirely different product. They are microfibre so will not scratch a lens if the hard grit is first removed, preferably with a dust gun or blower of some description. They will remove most smudges, if not too heavy, and can be used with a good lens cleaner fluid if you wish to remove the more stubborn grease marks. Once they become grubby, they are washable but, although the instructions do not say so, never use a fabric conditioner or a detergent that includes one as they will affect the fabric.
The cloth is not excessively large, at around 6-inches square, but is large enough for normal use. If you do not want to return it to its original packing after every use, I would suggest using a small self-seal poly bag to keep it as clean as possible.
