Why aren't lens/body caps transparent?

No! You want opaque lens caps because: Keep light out of the camera when not using it. In film cameras, the sensor is effectively always on. The shutter should in theory block all light, but stuff ...

Can a camera be affected by fungus?

Cameras can be affected by fungus, but in real world usage they usually aren't as vulnerable as lenses. There are a few reasons for this. Most lenses that have a fungus issue have been stored for ...

Is there a way to remove fungus without dismantling the lens?

UV light will kill the fungus, so all you need to do is let the lens be exposed to sunlight for a few days. Be sure to remove any UV filter you might have attached to the front of the lens. ...

Should lenses be stored without their caps inside a dry cabinet?

Light is only beneficial for inhibiting the growth of fungi if it contains ultraviolet (UV) wavelengths. The primary source of UV light among common light sources encountered most places is sunlight. ...

Why aren't lens/body caps transparent?

Interestingly enough, optics made for hunting rifles often come with transparent lens caps for both the front and rear lenses. This allows the scope to be used, albeit with less optical precision, ...

Why aren't lens/body caps transparent?

Lens caps are opaque to keep light out of the camera. This is something you really want when there's light-sensitive film in it rather than a digital sensor. Most shutters work well, but a tiny leak ...

What are these branching, dust-like particles? How to prevent their spread?

This is a fungus. It should be ok to take pictures with that - but only you can check that. Take some test shots of blank surfaces with different apertures, focal lengths and light coming from ...

Can fungi transfer from a vintage camera to different camera/lens if put together?

Fungus spores are already everywhere, so your DSLR and its lenses are already infected (and probably were since construction). But fungus needs high humidity to grow (which is why it's relatively rare ...

What is the little "haze" on my lens?

The camera lens is comprised on a mix of positive (converging) and negative (diverging) lens elements. This is necessary because as the light rays travel through glass, each color takes on a slightly ...

Is there a way to remove fungus without dismantling the lens?

UV lamps are available in the market. It would be better to put the lenses in an ordinary stainless steel container and put the UV on for few hours; don't look at it while it's on. I think it's ...

Can a camera be affected by fungus?

Fungus spores are everywhere. They land, and if conditions are decent, they germinate. The result is a colony of fungi. The secretions are acid and thus corrosive. Favorable conditions are present if ...

Why does fungus form in lenses, and how to get rid of it?

The belief that a lens with fungus can infect others nearby is nonsense. The spores that cause fungus to develop are in the air around us at all times, only "clean rooms" are likely to be free of ...
