Your technique for switching lenses in the field?

[TexPhoto]

It's important to remember, your sensor probably had scmuck on it when you purchased it. Even if you never change lenses it will add more scmuck over time. You lenses are not air tight, and neither is the camera. The lenses grow and shrink as they focus, much more as they zoom. This sucks more air in and out, brining in fresh air and squirting it around in front of the sensor. As the mechanical parts of the shutter rub against each other, they shed little pieces and create tier own scmuck.

Feel better?

Body facing up with lens on it set down on something. First push button and losen that lens without pulling it off yet. Hold other lens next to it facing up, remove end cap from bottom. Then fast swap and hold the one you took off the same way it came off with the open end down. Then put that end cap on that one. If you always do it that way and fast enough it's hard to get anything in there.

With camera hanging around your neck ...

1. Place lens cap on
2. Reverse lens hood
3. Reach into bag and take out desired lens
4. Remove rear element cap and place in pocket, keep the new lens in left hand.
5. With right hand press button and remove old lens
6. Place new lens on the camera
7. With left hand now free place rear element cap on old lens
8. Place old lens in bag.

I'm not very good at it myself and if I can I use a table or flat surface. If it's windy outside I'll use the bag for cover.

Better yet, choose a lens and stick to it.

This is exactly the same way I do it.

If I need both hands I will put the lens not being mounted on a camera body into my bag with the rear element down, so that it is somewhat protected from rain or dust, when the rear lens cap is off, but the front lens cap is on.

Taking into account all people that are rushing around during my shooting or high chance of hitting the ground with the lens in my workflow, this solution looks quite odd to me

It might work for photographers who work in rather stable environments though

Always take off first lens Before you attach the Second lens. 8)

Looks good for certain types of photography. A couple of issues come to mind:

1. Weather proofing. If you have all your lenses hanging about like that and it starts to downpour - you could be in trouble!

2. Thieves... obviously you wouldn't want to walk around like this anywhere that you were expecting thieves... they would get quite good at just coming up to you and twisting one of your lenses off!


This solution seems best for wedding photography and other type of (indoor) event photography where you're not really expecting thieves and you have some control over the weather...

1. Set up portable clean room
2. Put on clean room suit (otherwise known as a "bunny suit")
3. Enter portable clean room
4. Remove lens from camera
5. Unscrew cap from lens to be mounted
6. Mount lens
7. Screw cap onto originally-mounted lens
8. Exit clean room
9. Remove bunny suit
10. Break down portable clean room

This procedure is somewhat involved, but I have never gotten dust on my sensor!

An easier solution for those with deep pockets is to keep a body permanently attached to each lens.

Turn the camera off.
Push on the button on front of the camera and twist the lens off.
Twist the new lens on.
If the sensor gets dirty I clean it.
If I drop the lens I send it to CPS and they repair it.

Very basic technique but it seems to work just fine.


Edit; This post adds 1 to my post count. I am not sure why there would be a reason to post to this thread otherwise.
