This has been around for ever. It is true though. I personally am not one of those people that need to go into a clean room to clean off their lenses. I use my shirt. The qualifier to this I'll add is isolated bits of dust and dirt don't degrade IQ that much. Lots of fine scratches, like on the coating really do though. It's all just foggy.
The lens of my Ansco Memar Pronto lens is so hazed up the photos look like something shot with a pinhole, has a very dreamy effect. This favorable result is probably not the norm but I had several people want to buy the camera because of it. Nope I haven't sold it
Thanks, I do try to blow them all away but I seem to collect more every time I change lenses. It's nice to know exactly where the problem is though, I'll stop obsessively cleaning the front glass now! The big prob is I can't see them at the time, only later when I get the pics uploaded. I guess I just need to be a bit more careful.
I spotted a whole load of dandelion heads today at just the right stage for playing macro photography. I might nip out later and pick a couple up - I've never tried that classic shot yet.
Example of little black specks. There's one above the cloud on the right. What really annoys me is when I take a pile of pictures in a row, and these blobs are on them all in exactly the same place. Fixable but annoying! Cleanliness is the answer I suppose, difficult for one who spends so much time covered in a variety of unpleasant stuff.
I *think* I've got it clear now. If not I might take a wee trip into town and speak to some camera peeps. Interesting point about being able to see it at wider f/, never thought about it but all the blobby holiday pic were in France in bright sunlight so stopped down.
To celebrate the discovery of what they are and what I need to do I have bought a new lens on ebay - Canon FD 135mm. Just because. £15 inc postage
