i had a crazy genius idea

[craiglee]

so sometimes i need 2 lenses, but i don't want to waste time switching lenses. "can you hold on while i switch lenses?". very lame. so i had this idea of maybe a swivel thing that could hold 2 lenses and you just swivel a lens to the mount and the other lens would be on reserve. OR a rotating barrel like a revolver gun. i'm sure someone has thought of this before. i realize it would probably be heavy and big, but still it's an idea. anyone?

Kinda like the turrets holding multiple lenses on enlargers or movie film cameras

Problem is the EF mount lenses have contacts on them, whereas enlarger lenses or movie lenses did not have to have an auto diaphram mechanism or aperture setting from the body.

Or just carry a second body.

Franz Reichelt thought he had a genius idea too.

That turret ought to be arrested for being "ugly in public" ;):rolleyes:

In addition to issues with electrical connections you wouldn't be able to seat the lens into the mount on the camera body so it would be working like a macro extension tube causing you lose infinity focus.

it wouldn't mount onto the rig. it just a holster.

I'll second the second body.

And then there is the weight factor (with two lenses)

The revolving system isn't a bad idea but I don't see it being very practical. If only Canon had a system where if you purchase one body, register it and get another registered camera body for 20%-30% off, it would allow us photographers to work more efficiently. Then again, from a reselling point, it could be exploited...

Or just have an all in one lens. 16-200mm f/2. It would be the size of an elephant's trunk!

What'd be nice is a belt-system that allows you to strap/hang several lenses on your hip (think water bottle holsters), and easily have access to them (maybe just flipping open a cover or protector). I'd find that useful.

Or maybe such a product already exists?

ThinkTank, for one.

Kinda like this:

[edit] this page apparently does not allow you to link images. Copying this URL into the address bar displays a picture of an old RCA TV camera with 4 lenses on an axle.

There was a company that supplied what amounted to rear lens caps with 1/4" x 20 screws which were designed to mount into the tripod screw socket beneath the camera...

The rationale of this was that you could carry your camera with the shooting lens mounted on the camera with the extra lens mounted beneath the camera.

The idea never got off the ground. However it would be easy to fabricate one from an extra lens rear cap and a 1/4" x 20 screw..

My fear would be, that besides making the camera awkward and heavy, there would be a possibility of the lens becoming loose and falling to the ground. Imagine your chagrin if your new 17-55mm f/2.8 IS lens landed front element first on the sidewalk.

How do I shoot? I use two cameras on an OPTECH Dual Harness and this works perfectly...
