Lens Cleaning

It totaly agree this has gone totaly off subject all I wanted to know was. "When the time comes should the rear optic be cleaned the same as the front optic or should it be left to a professional? Any special precautions or useful links etc would be greatly appreciated" Kind thanks for all the a...

The straighforward answer is treat the rear element the same as the front element.

The straighforward answer is treat the rear element the same as the front element. Good idea John.... put a UV filter on it :shock: :wink:

I am now confident that it's OK to use carefull normal methods to clean the rear optic the same as I do the front. Because of the risk to the mechanics of the lenses, if required I will only use cleaner fluid by putting it on the cloth rather than spraying it onto the lens. Thanks to all David

I suppose porous is a bit too broad to describe the surface of glass? :shock: The correct term is hydrophilic If it's hydrophilic, it attracts water**. So why is that ROR product aimed at removing residual oil? Has anyone here actually used it? TBH, I don't think I'd take the chance - as...

ROR is superb stuff and my daughter uses it to clean her sight trial lenses, don't think Optometrists would use snake oil. Lenspen make a microfibre cloth that comes in their Lenspen sets, strange then to read the last few words of this paragraph Micro Klear - Deluxe Microfibre Suede Cleaning...

ROR is superb stuff and my daughter uses it to clean her sight trial lenses. Great that we have an actual user! Can you be a bit more specific, about why it's so good (and what are sight trials?)? I take it these lenses don't really let three times as much light through after cleaning with ROR...

Not sure about the three stops claim, but certainly works well on my lenses. Spray a small amount on a lens cleaning cloth, lightly rub in circular pattern centre out and they are crystal clear with all smudge marks removed If you wear glasses try it on them, not exaggerating when I say it makes yo...

Lens Cleaning

The rear element of the lens should need very infrequent cleaning as long as you keep a rear cap on when not in use, even then a blower should be sufficient to remove dust, "muck" should never really be a problem on the rear element if you look after the lens. As for the front element I use "wet"...

Nice to hear that leytono. It would probably be on a lens like this that you would gain several stops, especially if it was dirty :shock: Edit: Just noticed on the link to the distributor that Mannesty gave: Until now, the majority of lens cleaners have been simply silicone, alcohol or...

It would probably be on a lens like this that you would gain several stops Algi, I hate to keep banging this gong, but you're driving me bonkers! :D Are you aware that a 1.5 stop gain means almost 3 times more light? So if the cleaning fluid gains you 1.5 stops just by removing muck from the s...

Question is, or does overzealous cleaning do more harm than good. Ok nobody wants fingerprints, but a bit of dust isn't the end of the world. I'd love to see some evidence of a 1.5 stop gain. That it gets the lens clean I can believe, but almost anything will do that.

It takes more than a scratch or two to show up in an image, usually as flare. Ironically, the "blooming" of uncoated lenses by age resulted in reduced flare and increased contrast, which is how coating of lenses came about. A 1.5 stop gain is a pretty wild figure I think. Blooming does increase t...

I use a microfibre cloth or a Calotherm cloth. Or if its really greasy a drop of Eclipse and a pec pad. Eclipse fluid specifically warns against its use on lenses and filters. Personally, I'm using 20 year old Selvyt cloths.

if you are referring to Selvyt, printed on the side of the Eclipse bottle: 'READ CAREFULLY! Eclipse fluid is not recommended for use on filters and lenses.'

if you are referring to Selvyt, printed on the side of the Eclipse bottle: 'READ CAREFULLY! E2 is not recommended for use on filters and lenses.' OTOH: the bottle of Eclipse (not "Eclipse E2") that I bought from "Just" (AKA "Camea Clean"), see http://www.cameraclean.co.uk/product-detail.php?cat=11...

Perhaps they've changed their mind like they did with which camera sensors you could use the various versions on.
