Do you change lenses on the street?

I know this might be a really stupid question, but do you change lenses on the street?

I have read many threads talking about carrying several primes, such as 50 mm, 85 mm, and 105 mm, like I do.

However, I usually carry two cameras to avoid changing lenses.

I am just curious about your ways of doing this.

If you do change lenses on the street, wouldn't you worry about the dust going into the lenses?

How do you deal with that?

Thanks!

I change my lens when needed.

Avoid changing lenses in dusty environments.

When outdoors try and shelter the camera and lenses from the wind.

What I do is, take the second lens out and place it standing on a flat surface (or use the space for the camera in my bag).

I loosen the rear lens cap, but, leave on the lens.

Then with the camera pointing down I remove the lens from the camera.

I set the removed lens next to the other lens, and immediately switch the rear lens cap, just setting it loosely on top.

I pick up the new lens and put it on the camera.

Then I tighten the rear lens cap on the lens I removed an put it in my bag.

The camera opening is always facing down, and the rear of the lens is only exposed for a moment.
Only when I'm using my camera to take photographs.

Thanks.

Dust is ever present, one should periodically use a Rocket Blower to blow off sensor dust. Depending on the camera and environments its used in, a wet cleaning from time to time. It's debris that is blown about in breezy and windy conditions that I try most to limit an open lens mount.

My reaction to people who reply that "don't worry about frequent lens changes" ... wonder what their sensor looks like?

My speculation is that with a proper test (f22+ overexposed at clear, cloudless sky ... then greatly increase the contrast of the RAW file), they'd be shocked by how much sensor dust is there.

Thank you, Doctor Experience.

Indeed, it will.
 
Cameras, have interchangeable lenses for a reason.

How do you think us pros get the images we do? By leaving the same lens on all the time? No but choosing the right lens for the right shot.

As for the condition of my sensor, it's pretty damn spotless. It has to be; I charge for my work.

Spotting out dust on a neg was always part if darkroom photography, now it's part of digital photography. A second in Photoshop and it's gone.

Life it too short to worry about it.

Like this. In my earlier post I noted that there's one spot I need to remove (the one at top left). It took me rather a lot of PP (more than you suggest) to show the other marks.

Shocked as in "Gosh, look how clean it is"?

Incidentally, if you want to be shocked this is what my original K-5 with the sensor problem looked like

Paradoxically, any lens that extends and contracts for focus and or zoom acts like a pump, drawing air that can carry fine dust. Your conservative approach might make you feel good but may be no safer than some changing.

Think about how much effort you just listed to be able for dust to show up in an image.

Canon's sensor cleaning system is amazingly effective. Couple that with good lens changing technique and I've never had to wet clean my sensors. And have only had to use a rocketblower once on my Canon XTi (purchased used).
